The Four Horsemen of the Carbon Apocalypse
First image:
Black and white sketch of the famous Four Horsemen of the Apocalypse (figures in Christian religion that are symbolic warnings of the death and destruction that will occur at the end of days) in the style of Greek and Roman depictions of gods and goddesses and shows them armed with sword, scythe, bow, and scale, violently charging toward Earth at the end of the world.
Game Theory
First image:
Cartoon with a single stick figure alone on the page, line pointing from head to words above "Yes, from the evidence it looks pretty likely to me that we're causing global warming on a horrific scale. But with Science you don't need to argue. It doesn't matter who wins the debate - it's about reality. By just waiting a little longer, we'll get to see who was right. It feels unethical, but I find myself wanting to keep quiet about the science just to know for sure. As terrible as it sounds, the state of the world isn't really my responsibility. I'm just thrilled to get to watch. If the scientists are right --- and if we keep people from understanding just a little longer --- we'll enjoy quite a ride. And pragmatically, on the outside chance that they're all wrong, I get saved the embarrassment of having spoken up."
Understanding Carbon Lock-in
First image:
Ed. Note: Graph showing that CO2 parts-per-million and the Dow Jones Industrial Average (DJIA) have increased substantially together since the industry index's inception just before 1900. Both reached their highest points in history in recent years. CO2 measurements were at 294ppm in 1900, and the DJIA was at 48.6. After steady rises over 100+ years, CO2 was at 412.5ppm and the DJIA was at 28,600 in 2019.
Detail: Graph actually has no vertical (Y) axis, but the bottom or X axis ranges from the years 1799-1900-2020, with 1900 and the DJIA number for that year shown as 48.6, which is the starting point for a line that begins to rise approximately 40 years later, takes some jagged rises and dips until around 1980 or so then rises dramatically, with some market index plunges shown into the early 2000's, then a steep rise to 28.6 thousand, almost straight up with only a few minor dips, in 2019. Above this line is a comparative line showing CO2 parts per million, starting in 1799 at 282.8, then staying mostly flat with little change until 1900, where it has risen to 294.2ppm, and then around 1960 beginning a steady rise upward to 2019 where it rose to 412.5ppm.
Second image:
Three-panel cartoon depicts two stick figures, one on left with no hat and carrying a book, the other with a hat and not carrying anything. First panel: Figure with book says to the other: "I'm trying to fix a problem with the world. Can you help?" Second panel: Figure with hat says "It's obvious you don't actually care. If you did, you'd be trying to fix this Bigger Problem instead." Final panel of cartoon: Figure with book saying: "OK, want to help fix the Bigger Problem?" Second figure to the right (with hat) says "No, for another reason I'll think of later."
Change Is Here
First image:
Large-scale, full-page illustration of the sky superimposed with a chart. The sky is filled with thunder clouds or smoke, which grow in size in conjunction with the Y-axis of the line chart. There are 4 separate data lines on the chart - illustrating the increases over time, from Earth’s creation to present day - between rising carbon dioxide concentration, ownership of vehicles in the U.S., annual carbon dioxide emissions from coal, and cumulative plastics production. All of these emission sources have increased dramatically in modern times, especially over the most recent 120 years.
What Is Carbon?
First image:
Graphic shows one large square, divided into 545 small gray squares, representing the gigatons of carbon contained within various types of life on earth. There are 450 gigatons, depicted as 450 gray squares, of carbon contained in all plant life. In contrast, the graphic depicts bacteria with 70 squares, Fungi with 12 squares, Archaea with 7 squares, Protists with 4 squares, and animals, including humans, with only 2 squares.
Global Greenhouse Gas Emissions by Sector
First image:
Horizontal Bar chart showing the human sources of greenhouse gas emissions, broken into four major categories. Based on records of emissions from 2016, humans were responsible for 49.4 gigatons of greenhouse gas emissions.
Summary: "Energy" production and usage, broken into several sub-sectors, contributes the greatest share (73%) of global greenhouse gases at 36.1 gigatons. The next-largest component is much smaller, with "Agriculture, Forestry and Land Use" at 9.08 gigatons. "Industry" contributes 2.58 gigatons and "Waste" at a bit more than 3% (1.57 gigatons) of the total human-caused greenhouse gas emissions during that year.
More detail: Starting with the TOP or FIRST "Energy" graph, this category as a whole is responsible for 36.1 gigatons of the 49.4 gigatons in total CO2 emissions from all human activity. It is subdivided into Road Transport as the longest bar on the chart at 5.87 gigatons of CO2, then Residential Buildings at 5.38, Other Industry, 5.23, Unallocated Fuel Combustion, 3.85, Iron and Steel, 3.55, Commercial Buildings, 3.26, Fugitive emissions from energy production, 2.86, Chemical and Petrochemical, 1.77. Aviation, just under 1 gigaton at 0.93, is the next bar down on this first chart, then Energy in Agriculture and Fishing, 0.83, Shipping, same, then 6 other areas all under 0.34 gigatons each, ranging downward from Non Ferrous Metals to Paper & Pulp, Machinery, Rail, Pipeline and the last bar in the "Energy" category, Food & Tobacco, responsible for 0.04 gigatons of CO2 emissions. The SECOND Graph down is "Agriculture, Forestry and Land Use" carbon dioxide emissions. Of this category's 9.08 total gigatons, Livestock & Manure is the largest bar/portion at 2.86 gigatons. Next in order are Agricultural soils, 2.02, Crop Burning, 1.72, Deforestation, 1.08, Cropland, 0.69, Rice Cultivation, 0.64, and finally Grassland, at 0.04 gigatons of carbon emissions. The BOTTOM TWO charts of 4 on the page show "Industry" sources of carbon totaling 2.56 gigatons, with only two components, Cement at 1.48 and Chemicals, 1.08 gigatons of carbon emissions. The final chart at BOTTOM shows the "Waste" category, with two bars only also: Landfills responsible for 0.93 and Wastewater for 0.64 gigatons of carbon emissions.
Energy Production and Carbon
First image:
Ed. Note: The Energy Production and Carbon article references 5 separate, yet related graphs and charts below it. All highlight the links between energy production and carbon emissions, especially their relationship to dramatically increased human energy consumption since 1950.
Bar chart shows global primary energy consumption by source, as of 2019, with types of power sources shown in order of relative size, and includes the percentage of the total energy consumption for each source. Oil is the largest source at 33.1%, Coal and Gas follow it at 27% and 24.3%, respectively, of consumption by source. Other sources include Hydropower at 6.4%, Nuclear energy at 4.3%, Wind, 2.2%, Solar, 1.1%, Biofuels, 0.7% and all Other Renewables comprising less than 1% of global primary energy consumption sources.
Second image:
Pie chart summarizes the prior exhibit by showing global energy consumption as being 84% Fossil fuel-related and 16% from Non-fossil fuels.
Third image:
Line graph shows renewable energy vs. fossil fuels, with the line representing fossil fuels rising rapidly along the X axis (years from 1950-2019) to 148,000 TeraWatt hours of power produced in 2019, while the line representing renewables rises much more slowly to 25,000 TeraWatthours in 2019.
Fourth image:
Line chart shows "Total emissions, 1950-2019" with emissions from all energy sources rising from 5.9 gigatons more than six-fold to 36.7 gigatons during this timeframe.
Fifth image:
Line chart shows the top emission sources in gigatons from 1970 through 2020. Oil, at 6.8 gigatons, is the top source, and line, in 1970, with coal following at 5.7 gigatons, and gas at 1.8 gigatons. The chart shows that in 2020, coal has surpassed oil as the top energy emission source at 14 gigatons, oil at 11.1 gigatons and gas at 7.4 gigatons.
Construction’s Carbon Debt
First image:
Bar chart titled "Manufacturing and construction emissions'', shows that building use of electricity and heat is nearly double the next-highest emissions source, material manufacturing, at 6,855 megatons of CO2 vs. 3,430 MtCO2, respectively. Other sources on this chart are Building use of natural gas, oil and coal which, combined, total less than one-third of the top two sources. The chart shows that building construction is the smallest source of emissions.
Second image:
Pie chart shows "Energy-related emissions" with two segments: "Manufacturing & construction" (all of the emission sources shown in the “Manufacturing and construction emissions” bar chart) at 38% of all energy-related emissions, and "All other sources", 62%
Third image:
Line chart titled “Buildings climate tracker,” measuring the decarbonization index trend for buildings and construction. The X axis covers 2015 to 2019 in one-year increments. The line representing the decarbonization goals to reach zero carbon building stock by 2050 bisects the chart. The second line starts by tracking the goal but then falls annually, showing the building sector’s actual progress. The index finds that annual decarbonisation progress is slowing down and has, in fact, almost halved from 2016 to 2019. While the number of building sector CO2 emissions reduction actions are growing, the rate of annual improvement is decreasing. To get the buildings sector on track to achieving net-zero carbon by 2050, all actors across the buildings value chain need to contribute to the effort to reverse this trend and increase decarbonization actions and their impact by a factor of 5.
Fourth image:
Single panel cartoon showing a middle-aged couple doing gardening/yard maintenance in their front yard, one with the handle of a rake in his gloved hand. This man is pointing at their next-door neighbor, rake on the ground at her feet, with her gloved hands and arms stretched around a corner of the house next door in a loving embrace, with hearts emanating from her closed eyes and a smile on her face. The man in his yard gestures toward the happy neighbor behind him and says to the woman next to him - as she's placing their own yard's clippings into a recycling bag - "She's been acting like that ever since she made her home energy efficient."

Why Are the Greenhouse Emissions Numbers So Confusing?
First image:
Two pie charts found online and used in several carbon emissions related articles, intended to demonstrate carbon dioxide sources by sector and sub-sector. As the caption indicates, one is often considered to be difficult to understand, and one is often considered to oversimplify the data.The “complex” pie chart shows the sources of carbon emissions, with “energy” comprising 73% of the pie. Another circle is drawn outside of the pie and shows the breakdown of various subtypes of the various sources in the base pie, and there are two more circles outside of that attempting to break down the information even further. The simpler pie chart categorizes carbon dioxide emissions in a way so that “electricity” is 25% of the pie and does not show the overlap that exists between activities in real life.
Second image:
A complicated infographic that attempts to illustrate the multitude of ways a typical company emits greenhouse gases, both directly and indirectly. The chart has three different layers. From bottom to top, the first layer divides activities a typical company undertakes in reporting Upstream and Downstream carbon emitting activities. The second layer of this illustration attempts to group activities under Upstream/Downstream activities, except some activities cross-over between more than one, with the exact amount undefined. It shows a series of arrows, corresponding to "Scopes" 1-3 indicated by "U-shaped" arrows displayed across the page. These scopes are further divided into indirect and direct functions, which are themselves comprised of individual activity areas, i.e., "Purchased Goods and Services", "Business Travel", "Company Vehicles" and "Transportation and Distribution" are four of eighteen areas shown where a typical company generates emissions. Then, the third layer, at the top of the graphic, shows seven greenhouse gas elements, represented by images of clouds and scientific labels, from CO2 on the far left to HFCs in the middle and NF3 (Nitrogen trifluoride - an extremely strong and long-lived greenhouse gas used in the production of flat-panel displays, photovoltaics, LEDs and other microelectronics) on the far right.
The Plastic Lifecycle
First image:
Line chart shows the expansion of global plastics production from 1950-2015. From around 2 million tons near the beginning of this period and then extending upward at a consistent, steep angle of approximately 45 degrees until 2015, the chart line shows total global plastics production has increased 1900%, reaching 381 million tons across the sixty-five years measured.
Balance in the Earth’s Carbon Cycle
First image:
Two illustrations accompanying this Carbon Almanac article. The first is a sketch of a large wooden barrel, with a huge amount of liquid entering it and splashing over its top. It's labeled "carbon-cycle imbalance" and flowing into the top of the barrel are "emissions", labeled as 700 gigatons of carbon released into the atmosphere. At the bottom of the barrel there is a very small spigot, which is labeled and draining out "Net removals" representative of carbon removed from the atmosphere. More detail comes from a line chart positioned directly below the barrel illustration, showing the "difference between emissions and sinks (carbon imbalance) over 7 decades." This chart displays the years from 1950-2020 along its bottom, X axis. Running on a fairly steep curve upward during nearly every portion of this annual progression, the top line on the chart represents "Carbon Emissions", which started in 1950 at 3.1 gigatons of carbon dioxide per year and reached more than 3 times that amount, or 10.4 gigatons/year, in 2020. The bottom line of the graph represents amounts removed from the atmosphere by "Carbon Sinks", beginning with 2.7 gigatons in 1950, and it has risen and fallen several times per decade from then until 2020, when carbon sinks removed 6.1 gigatons per year. Text between the two lines reads: "excessive carbon in the atmosphere is pushing us out of balance". Though more carbon is being removed now than 70 years ago, carbon emissions have increased at a higher rate. In fact, the gap between the two in 2020 is much larger on an actual and percentage-difference basis than it was in 1950.
Carbon Dioxide on Earth over Time
First image:
Line graph shows Carbon dioxide concentrations in the atmosphere along its X/bottom axis from 800,000 years ago until 2019. The line on this simple chart shows substantial rises and falls over the millennia, with a low point shown of 171.6 parts per million (ppm) of CO2 around 650 thousand years ago, during a glacial ice age, and then a high point in the ancient period occurring approximately 350 thousand years ago, when carbon dioxide concentrations were at 300 ppm. As the line moves through the last 200 years, it trends up very sharply and consistently to a 2019 average CO2 concentration of 409.8 ppm in 2019, at least 30% higher than ever measured previously.
Food Loss and Waste
First image:
Pie chart titled "Contribution to greenhouse gas emissions." 'Food waste and loss' represent the smallest portion of human-caused greenhouse gas emissions, at 6% of the total. The next-largest component is emissions from 'Food eaten', at 20%, and the largest slice of the "pie" , at 74%, is human-caused emissions categorized as 'All other sources'.
The Five Scenarios Outlined by the IPCC
First image:
Line chart with 5 lines, the estimates of carbon dioxide emissions that would follow each of five future emissions scenarios - or Shared Socioeconomic Pathways (SSPs) - projected for the world by the IPCC, from 2050 forward, based on actions that (might be) taken today - or not - by people and governments of the world. It shows the baseline in 2015 for each scenario at just over 39 gigatons of CO2 emissions, with the first scenario (or SSP) "very low emissions" trajectory trending from there to 2100 on a sharp downward path, with a projection reaching 1.9 gigatons, or near-net zero carbon emissions, or even lower, to a potential removal of 13.9 gigatons of CO2 from the atmosphere. The second and third scenarios show similar results, but not quite as positive projected impacts, at 2.6 gigatons to a potential of -8.6 gigatons (below net-zero) and 4.5 to 9.7 gigatons, respectively. The fourth and fifth SSP lines display much higher endpoints on the chart, with the second-highest and highest carbon emissions projections of any of the five scenarios, at 7.0 to 82.7 gigatons and 8.5 to 126.3 gigatons for the very worst projected IPCC SSP carbon emissions outcomes.
Second image:
Table showing each SSP scenario number and its projections for change in average world temperature with a description of actions that might contribute to achievement of each scenario. Below that table are two separated, large illustrations of both "Low" and "High" emissions IPCC scenarios. In the left panel of this illustration, the Low emissions scenario is depicted with a polar bear standing on arctic sea ice, with a rain cloud and a typical rain pattern coming from it at top and verbiage "2.4% increase in global average precipitation over land." The other key indicators accompanying low emissions are also shown: a thermometer with the words "1.4°C increase in global surface temperature", and an arrow pointing upwards and labeled "0.38 meters rise in global mean sea level”. Below the arctic ice ledge where the bear is depicted at sea level are the words "2.4 10⁶ Km² of September minimum Arctic sea ice". The right panel depicts the High emissions scenario. It shows a cloud raining heavily over a barren and much thinner ice ledge atop the Arctic sea. Verbiage above the cloud reads "3.5x worse" in bold type, then in normal type "8.3% increase in global average annual precipitation over land." Other indicators in this illustration are a thermometer showing a higher temperature than in the first, Low emissions illustration. Next to it it says, in bold type "3.1x worse" and then "4.4°C increase in global surface air temperature." Below, an arrow points upward next to, in bold, words reading "2x worse", then "0.77 meter rise in global mean sea level." Finally, below sea level, much closer to the surface to illustrate more significant melting, is printed in bold "8x worse" and then "0.3 10⁶ Km² of September minimum Arctic sea ice."
The Climate Cost of Gas-Powered Leaf Blowers
First image:
Side-by-side illustration depicts "The Climate Cost of Gas-Powered Leaf Blowers" by showing a handheld gas leaf blower with the words “1 hour of leaf blower use” on the left, an equal sign in the middle, and a drawing of a car on the right and the words "1770.278 kilometers driven in a Toyota Camry." to show that each of these disparate activities are roughly equal in carbon emissions impact. This is quite surprising because at 60 mph/37.2823 kph, this means the car would be driven for almost 47.5 hours to generate the same carbon emissions as the gas-powered leaf blower in one hour!
The History of Systematic Measurement of CO2
First image:
Line chart represents "CO2 parts per million (ppm), 1958-present" and is based on measurements taken at Hawaii's Mauna Loa Observatory. Beginning in 1958 at 214 ppm of measured CO2, the single trend line on the chart rises at a fairly sharp angle until 2021, when the concentration of carbon dioxide reached 416 ppm according to the Mauna Loa instruments. One other note on the chart along its bottom shows the "Baseline average over the prior 800 thousand years" as being 275 ppm of CO2 in the atmosphere.
Understanding the Five Scenarios
First image:
Line chart illustrates the following statement: "A sea-level rise of nearly one meter could impact the lives of nearly a billion people living in coastal regions, islands, and areas currently prone to flooding." Two scenarios are depicted, each with higher/lower outcome estimates from the years 2020 through 2100 shown on the X/bottom axis. One scenario incorporating sea-level rise estimates for Shared Socioeconomic Pathway (SSP) Scenario #1 shows that the projected increase in temperature of 2.6°C (above pre-industrial temperatures) for this scenario by 2030 and continuing at this temperature level or lower through 2100 will result in a sea-level rise of 59.8 cm. There are dotted lines to show the results if estimates come in at the higher or lower ranges of this projection. The same approach is taken to display the estimates for SSP Scenario #3, which at its midpoint would include a temperature increase by 2100 of 3.6°C above pre-industrial levels and additional carbon emissions of 7 gigatons per year vs. 2015 levels. These two factors combined are projected to raise sea levels by 83.8 cm by 2100.
Heat and Health
First image:
Table shows the "Health impacts of exposure to extreme heat", separating these into "Indirect" and "Direct" Impacts on the left and the right of the table. Indirect Impacts include Accidents (indicated by a drawing of a drop of blood falling from a pricked finger) such as Drowning, Work-related accidents, and Injuries and poisonings. The next Indirect impact is Transmission of Food and waterborne diseases and Marine algae blooms (including drawing of a pig), the last two Indirect impact types are Disruption of Infrastructure (Power, Water, Transport, and Productivity - all indicated by a drawing of an electric power transmission tower) and Health services including More ambulance call-outs and slower response times, Increased number of hospital admissions, and Impact on storage medicines. A drawing of an ambulance illustrates this final Indirect Impact type. On the right side of the two-part table, Direct Impacts are shown as Heat Illness - indicated with a drawing of a thermometer and an upward moving arrow and including Dehydration, Heat cramps, and Heat stroke, then Hospitalization (hospital drawing with a cross in center) including Stroke, Respiratory disease, Diabetes Mellitus, Renal disease, and Mental health conditions. The final Direct Impact of human exposure to extreme heat listed in this table is Accelerated Death, illustrated by a skull drawing. This category includes Respiratory and cardio-vascular disease, and Other chronic diseases (mental health conditions, renal disease.)

Human Migration Away From Inhospitable Land
First image:
Bar chart titled "Weather-related human displacement in 2020" shows six principal causes of such movements: 30 million people were displaced in 2020 by climate related events. Storms and Floods represent the largest segments, affecting 14.6 million and 14 million respectively. A very distant third on the list is Wildfires at 1.2 million annually, and Landslides (102 thousand), Extreme temperatures (46 thousand) and Droughts (32 thousand) are the last three bars on the chart.
Second image:
Bar chart ranks the "Five countries with the most new displacements by disasters in 2019". Five countries are shown with the top being India with 5 million people displaced by disasters, then Philippines and Bangladesh (both 4.1 million), China (4 million) and United States (0.9 million).

Job Transition from Fossil Fuels
First image:
Satellite photo-based illustration of the United States, showing the individual counties in each of the 50 states, each shaded to represent the percentage of residents employed by the fossil fuel industry. Darker shades of gray have a higher percentage of residents working in the fossil fuel industry, and the map shows this in known petroleum-producing states like Texas, Wyoming, Pennsylvania, Louisiana, West Virginia, and Oklahoma, plus Alaska, Colorado, North Dakota, and "lighter" shaded states with some fossil fuel employment - Montana, Utah and California.
Second image:
Graphic illustrates total jobs in several energy-producing industries by using multiples of individual human solid stick figures in groups of 25, stacked on top of each other by category. Each represents 50,000 jobs among the World Total of 11 million jobs in this general sector. The largest category is Solar Energy, with 4.45 million, or more than a third of the worldwide energy industry employment total. Continuing down the list are Bioenergy (biomass, biofuels, biogas) at 3.2 million, Hydropower and Wind Power (both 2.05 million), and Geothermal (100 thousand).
The Impact of Global Tourism
First image:
Line graph depicts "Transport-related CO2 emissions" (in millions of tons). X axis ranges from 2016-2030. During this time, projections for transport-related tourism emissions (using present usage figures and patterns) are highest for Domestic Car travel, starting from 550 million tons in 2016 and increasing to 627 million tons by 2030. Just below this total are emissions from International Air transportation, projected to increase substantially from 397 million in 2016 to 616 million by 2030. Domestic Air travel, the third line on this chart, was responsible for 282 million tons in 2016 and is expected to reach 376 million tons by the 2030 end date for this study. One related infographic sits next to this chart. It's a drawing of a suitcase with an extended handle, bearing "stickers" on its side showing all the activities which comprise global tourism, ranked by percentage of the total emissions for the industry. 49% Transport, 12% Goods, 10% Food and Beverage, and 29% in "Other" tourism-related categories.

Hot Droughts
First image:
Vertical bar chart depicts the percentage above or below normal of "Summertime highs in the American Southwest", with shaded bars representing below normal and dark bars for above normal temperatures. This chart begins in 1910 and ends in 2021. It shows that from 1910 through the end of the century, Summertime high temperatures in this region frequently dropped as much as 50% or more below average and only occasionally edged close to 50% above average. After 2000, it became common, as noted by the majority of dark bars on this portion of the chart, for temperatures to exceed averages by 30-50% and in about 5 years leading up to and including 2021, to reach 70% or more above normal high temperatures for the summer in the Southwest.

The caption reads “CO2 emissions for each of the passengers on a commercial space flight would be between 50 and 100 times more than the one to three tons of emissions that are generated per passenger on a long-haul airplane flight.”
Impact to Peatlands
First image:
Vertical bar chart titled "Global Distribution of Peatland" notes the four countries which collectively hold 81.9% of all peatland on Earth. Russia is the first and largest with 1.4 million square kilometers of peatland within its borders, followed by Canada with 1.1 million square kilometers, then Indonesia, 266.5 thousand km², USA, 223.8 thousand km², and all other countries, containing 664.2 thousand square kilometers of peatland.
How Much Land Would It Take to Power the US through Solar?
First image:
In addition to a table showing the amount of land required for generating electricity, categorized by source, there is also a graphical representation of the 48 continental United States as part of the article "How Much Land Would It Take to Power the US through Solar?" This graphic notes that of a total of 9.834 million square kilometers of land in the continental US, an area of solar panels smaller than the size of the Mojave Desert, or 124,000 square kilometers (8 million acres) would be needed - and only for five hours - to generate enough electricity to power the United States for an entire day.
Greenwashing & Recycling Theatre
First image:
Line chart showing "Percentage of waste recycled by material type" with the X/bottom axis showing years ranging from 1960-2018. Three lines begin at 1960 along various slopes showing the percentage of specific materials that are successfully recycled. The top achiever on this list is paper and cardboard, which began at 17% in 1960 and in 2018 reached the 68% recycled mark. Glass is the next highest starting at only 2% in 1960 and rising to 25% recycled in 2018. The final line on the chart - representing plastic - shows how there was zero recycling of this material in 1960, and just 9% recycling of plastic waste by 2018.

Chart titled "Energy Distribution" shows predominant types of materials that have been used to produce energy between 1810 and 2019, which is the distance in years across the bottom of the chart. Wood was by far the largest energy producer from 1810 until the end of the 19th century, and then began to decline. Coal (shaded in black) surged into use beginning in the mid-1800s and gained prominence over Wood at the beginning of the 20th century, beginning to decline around the 1980s, then dropping substantially and leveling off thereafter at roughly 35-40% of its peak. Oil is the next source profiled (in a shade of very dark gray) and it emerges on the scene in the late 1800's and within a few decades equals Coal's output as a fuel and has remained the largest source thereafter up to 2019. Natural gas emerged and grew steadily in usage from the early 1900's until it plateaued at approximately 20% of overall power output. Finally, Renewables are shown as a relatively recent source of energy, and a note to the right of the chart states that Renewables make up 15% of energy sources as of 2019. The other sources listed previously make up the other 85% of all energy produced.

Three line graphs with the heading, "Change in CO2 emissions and GDP per capita over time." Each chart has a solid line showing change in GDP between 1990 and 2020 and a dotted line showing CO2 emissions over the same time period. The first country, Nigeria, shows a dip in both GDP and CO2 in the late 90s/early 2000s, followed by a steady increase in CO2 emissions (up 63%) and a more uneven increase in GDP (with many ups and downs) at 51% increase over 1990 levels. The second country, Romania has seen a steady decline and then leveling out of CO2 emissions, down 41% since 1990. Meanwhile GDP has risen steadily, with a few dips, ending at +117%. The third country, the United Kingdom, held CO2 emissions steady through approximately 15 years of economic growth and then began steadily cutting emissions so that they are down 34% relative to 1990. The UK's GDP is up 37% over 1990, having taken a dramatic hit after Brexit.

Summer 2012, I read headlines about a global warming "pause" and hope that maybe things aren't so bad. 2013-2021, I read more about climate science and get steadily more alarmed. Spring 2016, I read the 1982 Exxon Report. June 2020, Global 60-Month average reaches +0.94 degrees C. Easton, PA is 2 degrees C hotter than normal for the fifth year in a row. Today." Just above today is an X enclosed in a circle and labeled "1982 Exxon prediction."

How Much Carbon Are We Talking About?
First image:
Graphic stretching the length of the page and comprising 10,000 small dots. All but 4 of these dots are light gray. Three in the middle of a column are black, which represents the amount of carbon in each breath of air. The remaining 9,997 parts of a breath of air are other elements. Close to the three black dots is a fourth black dot, representing the increase in carbon since 1968.
What Do I Get for 1kg CO2?

Ten line art drawings showing how CO2 is produced during common activities. All activities have been scaled to 1kg CO2. Shower: 10 minutes, 40 watt light bulb: 25 hours, 73 Emails, 200 Google Searches, 10 average size Apples, 180 plastic grocery Bags, LED light: 125 hours, Owning a dog: 1/2 day, Walking: 24km, Mobile phone: 0.016 iPhone, Raising a child in North America: 12 minutes, Jeans: about 10 square inches of denim, Boeing 737-400 plane: 7km/passenger, Bus ride 80% passenger load: 9.5km, Car ride: 8 km, Cycling: 48 km, Beef: 35 grams, Charcoal BBQ: 22 minutes, 2 average size Avocados, 2 kg Broccoli, 100g Cheese, 5 average size Eggs.
Our Choices Can Have a Lethal Impact
First image:
Infographic titled, "How many people does it take?" shows how many theoretical people it takes in the United States, Brazil, and Nigeria to produce 4,434 metric tons of CO2. United States: 3.5 people; Brazil: 25 people; Nigeria: 146 people. 3.5 Americans produce as much CO2 as 146 Nigerians.
10 Myths About Climate Change
First image:
Bar graph shows the changes in the global average surface temperature (in degrees Celsius - °C) since the beginning of the industrial revolution. From about 1880 until 1940, the average surface temperature change fluctuated but all fell below 0.0°C baseline . From 1940 to about 1980, there were periods of change that fluctuated above AND below the baseline of up to 0.2°C. Since 1980, the trend in average surface temperature shows that all anomalies were in excess of the baseline, ranging from an increase of 0.2 to 1.0°C where we are today.
Second image:
Line graph shows the changes in the price of electricity from new power plants per kWh from 2009 to 2019. The price for a new coal fired power plant is nearly unchanged ($111 to $109 in kWh during this period. The price to build an offshore wind farm has dropped from $359 per kWh to $41 per kWh. The cost to produce solar (photovoltaic) power is down from $135/kWh to $40/kWh.
Third image:
Illustration depicts a large recycling receptacle with a steady stream of many different recyclable materials flowing into it. The large number 9 is the percentage of plastic (regardless of the symbol stamped on the plastic) that is recycled, emphasizing the small fraction that is actually recycled while the rest is left to be incinerated or accumulated in landfills or oceans.
Smoke Signals: A Global Warning from Australia
First image:
Line graph shows the historical changes in the temperature in Australia. The baseline is the historical average. The data starts in 1910 and through most of the 1950s, the change in surface temperature is largely below the average. The trend then moves above the average steadily increasing from the early 1970s up to nearly 1.5°C above in 2020.
The Relationship between Population Growth and Emissions
First image:
Circle made up primarily of human figures, with one sector filled instead with images of cornstalks. The image evokes the Pacman character of the popular video game, which is essentially a pie with one slice removed, to represent Pacman’s mouth. Human figures comprise the Pacman, and cornstalks fill its ‘mouth.’ The image invites the reader to ask: Is the population growing larger and larger and will there be enough food (represented by the corn) to sustain life?
Second image:
Line graph compares the CO2 concentration in the atmosphere and the global population throughout history. Starting in 5000 BCE, with a population estimated at 5 Million, the global population is represented by a flat line, showing very consistent population levels until the industrial revolution where the line turns 90 degrees straight up all the way to 7.7 Billion people. Over the same time, and following the same trajectory, the CO2 concentration in the atmosphere is a flat line at 258.1 ppm (where it is stable for 1000s of years) until it curves sharply upward to 412.5 ppm in the 21st century.
The True Cost of Plastic
First image:
Infographic illustrating the percentage of plastic that is successfully recycled. In this image we see the number 8300 in an extra-large font (the number of million tons of plastic produced). Of that 8300 million tons, 5800 million tons of the plastic (shown in a slightly smaller font below) is used only once. The number 500 in yet a much smaller font represents the 500 million tons of plastic that is recycled each year. Beneath that, in the smallest font, only 100 million tons of plastic are successfully recycled and still in use.
What Is an Ecosystem?
First image:
Four frame comic strip, beginning with two stick figures pointing to a line graph. Line graph shows time on the bottom X-axis, and the Y axis progresses from “good” to “bad.” The line graph shows a clear upward trajectory, with “now” labeled as just below the “bad” delineation. The figures say, “Here’s the situation: This line is here. But it’s going up towards HERE,” as one points to the “bad” section.
In the second panel, a bystander in a hat says, “so things will be bad?” Presenter says, “Unless someone does something to stop it.” Bystander says, “Will anyone do that?” Presenter says, “...We don’t know. That’s why we’re showing you this.”
In the third panel, the bystander is out of the frame, but their words float back, “So you don’t know, and the graph says things are NOT bad.” Presenter answers, “But if no one acts, they’ll BECOME bad.” In the final panel, the bystander says, “Well, please let me know if that happens!” Presenter says, “Based on this conversation, it already has.”
The Diffusion of Innovations
First image:
Graph of a bell curve illustrates the speed at which people adopt new ideas. True innovators make up only 2.5% of the population, and make up a small portion of the left side of the curve, very close to the X-axis, which is 0%. Next, early adopters make up 13.5% of the population, shown by the upward slope of the curve. The next group to embrace new ideas or innovations are the Early Majority at 34% of the population, with which the bell curve reaches its apex. These first three groups represent half of the population. The remaining half of the population is the Late Majority group (at 34% the same size as the Early Majority), and, as the curve slopes down and ultimately reaches the x-axis again, the Laggards are depicted at 16%.
What is Climate Change?
First image:
Stylized line graph depicts the Y-axis as a thermometer, starting at 0°C and moving up to 1°C. The X-axis is the severity of the weather. Instead of a traditional line, there is an illustration of a storm. On the left side of the illustration, the top of the clouds lines up with the 0°C of the Y-axis thermometer. The top of the rain cloud rises up to the 1°C mark of the thermometer as the severity of weather increases along the Y-axis. As the graph progresses, the severity of the weather increases, showing heavier rain, thundershowers, lightning, hail, and cyclones, typhoons and hurricanes as the earth's temperature increases by 1°C. The weather severity is illustrated with increasing intensity in the clouds, as well as in the precipitation and wind.

Understanding the Greenhouse Effect
First image:
Image shows the earth, its atmosphere, and the sun twice, right next to each other. The earth on the left shows a thin dotted line as the atmosphere, and represents the earth before humans began burning fossil fuels, when heat easily escaped the atmosphere with just a little bit being reflected back onto the earth. The caption on the left reads, “Before humans began burning fossil fuels, heat easily escaped the atmosphere.” The earth on the right shows a much thicker dotted line as the atmosphere. The caption to the right reads, “As greenhouse gasses accumulate, more heat is reflected back into the atmosphere.”
Carbon Inequality, Climate Change, and Class
First image:
Infographic depicts one large person superimposed on a large gray arrow, pointing upward, with the value of 15% in the arrowhead, illustrating that the richest 1% contribute 15% of global emissions. Next to this image, there are five rows of ten human figures that together are the same height as the single large figure. The arrow that they are superimposed on is smaller, with the value of 7% in the arrowhead, showing that the 50% of the poorest population together contribute only 7% of the global emissions. The caption reads, “The richest 1 percent of humanity was responsible for 15 percent of global emissions compared to 7 percent from the poorest 50 percent. That's more than double the emissions from a small fraction of the people.”
Urban Heat Islands
First image:
Image of a dense urban skyline surrounded by arrows that symbolize energy, heat, and emissions that are directed back down on the city in an arc. The caption reads, “Cities trap heat due to pollution from factories and transportation, and materials such as concrete and asphalt. And the air conditioning used to cool us down emits more heat and even HFCs.
Heating the Outdoors with Patio Heaters
First image:
Line graph of the Google search interest in the phrase "patio heater" from 2017 through the end of 2021. From a baseline of interest in 2017, you can see a substantial pick up in interest in the fourth quarter of each year (as winter approaches) which then drops back down as the weather warms up. In 2020, there was a spike of interest in the second quarter, and then in the fourth quarter, interest picked up by about a factor of three in magnitude. Interest in 2021 did not return to the baseline until midway through the year, and the fourth quarter spike of interest was less than 2020, but greater than that of 2017, 2018, and 2019.
The Energy Cost of Plug Loads

Image shows an arrow labeled O3 (the chemical symbol for Ozone) pointing down to a wilting flower.
Where Does All the Carbon Go?
First image:
Pie chart shows 25% of carbon dioxide is absorbed by water, about 30% of carbon dioxide is absorbed by plants and the associated soil, leaving about 45% of carbon dioxide produced that is not naturally absorbed.
Temperature Change on Earth
First image:
Line graph shows the average annual temperature of the years between 1961 and 1990 of 14°C (57°F) as a straight horizontal dotted line. This is used to allow the viewer to compare this to the variation of the average surface temperature over the last two thousand years. The annual average temperature changes show a predictably cyclic style of peaks and valleys, that range between the comparable 14°C at the highest end, and 0.4°C below that for one thousand years. The range decreases then until the high point is roughly equivalent to the low point for years 0CE through 1,000 CE, until it begins steadily increasing around 1900 CE, and spiking to 0.7°C above the comparable average of 14°C.
The annual actual temperature (in recent years where we are confident of its accuracy) sets the "zero point" for the Y-Axis for temperature change from average. It is quite significant to see substantial variation in the average temperature over the centuries following a predictably cyclic style of peaks and valleys that are associated with longer term weather patterns. The cycle takes a large and significant increase in the temperature increase of over 1°C in about 100 years that is not consistent with the patterns of the last two millennia.
Second image:
Line graph compares the global temperature and the amount of sunlight that reaches the earth during the period from 1880 to 2020.There is a mild inverse relationship between the two through the early years, suggesting that new equilibriums are reached as the greenhouse gas production increases. There is a dramatic increase and divergence between the two beginning around 1960 and accelerating around 1990, showing that while the radiance from the sun has decreased since 1990, the global temperature has increased.
Beyond the Polar Bear—Animals on the Edge of Extinction
First image:
There is an image of each of the listed endangered animals next to the name. The left hand column lists Tigers, Bumblebees, Whales, Asian Elephants, African Elephants, Snow Leopards, Mountain Gorillas, Polar Bears, Monarch Butterflies, Giant Pandas, and Sharks. The column on the right hand side lists Giraffes, Insects, Coral Reefs, Ringed Seals, Atlantic Cod, Koalas, Leatherback Sea Turtles, Adelie Penguins, American Pikas, Orange-spotted Filefish, and Green Sea Turtles.
Carbon Feedback Cycles
First image:
Illustration of the carbon feedback cycles (positive and negative) on the earth in a circular image. The concentration of atmospheric carbon (shown at the bottom of the circle) influences climate change as measured by temperature increases (at the top of the circle) directly by radiative forcing (through the circle).
The circle is labeled in four places as Climate Change at the 12 o’clock position, Land Carbon at the 9 o’clock position, Atmosphere Carbon at the 6 o’clock position, and Ocean Carbon at the 3 o’clock position.
There are four arrows labeled as Carbon Uptake, Partial Pressure,Fertilization Effect, and CO2 Solubility.
An arrow arcing down from Climate Change points to Land Carbon, (the total vegetation and soils). The surface temperature affects the CO2 solubility and human respiration. The CO2 released by human respiration is absorbed in the Land Carbon, (the vegetation and soils on the planet). From Land Carbon, an arrow labeled Carbon Uptake points to Atmosphere Carbon. The changes in CO2 solubility impact the carbon that is absorbed by the ocean. The ocean solubility is also affected by the partial pressure of the atmospheric carbon. When the amount of carbon in the atmosphere is not in equilibrium with the ocean and land, it cannot be absorbed, increasing the Carbon content in the atmosphere, contributing to climate change.
Meanwhile, an arrow labeled Fertilization Effect points from Atmosphere Carbon back to Land Carbon. The amount of carbon the land can absorb is impacted by the Fertilization Effect, and the carbon that is not absorbed by land contributes to the Atmosphere Carbon, which impacts the Fertilization Effect. Similarly, another arrow labeled CO2 solubility arcs down from Climate Change at the 12 o’clock position on the circle, down to Ocean Carbon at the 3 o’clock position. An arrow labeled Carbon Uptake points from Ocean Carbon down to Atmosphere Carbon at the 6 o’clock position, while an arrow labeled Partial Pressure points from Atmosphere Carbon to Ocean Carbon.
As the atmospheric carbon increases, the plants are less healthy and are unable to absorb more carbon.
Paving the Planet
First image:
Image of the country of Germany that shows every road that has been built in the last 200 years. Population density is clear based on the number of roads depicted. The significance of this type of map is that the geography and the population distribution of the country is illustrated based on where the roads are. No matter what country you live in, what state, or what city, we see that we are defined by our roadways. While no other features are marked on the map, the hills and valleys are obvious as the roads traverse around them, and the sparser web of roads are the less populated areas. How does this make you feel? Is your life defined by the miles you drive? Are there changes that you are now thinking about making?
The Impact of Thawing Permafrost
First image:
Image of a melting earth in an ice cream cone. The earth has a frowning face and steam or smoke above it. The reader is invited to consider if the earth is angry that it is melting. How do you feel about this?
Flooding
First image:
Line graph shows the sea level increase between 1880 and 2020 as measured by a change from the weighted average sea level over the 15 year period from 1993 to 2008. It fluctuates a little bit, but is largely a straight line increase between 1880 and 2020. In 1880, the sea level was 18.3 cm BELOW the weighted average sea level and in 2020, the sea level is at the highest point measured at 6.2cm above the 1993-2008 average. This is a total of 24.5 cm increase over the 140 year period.
Hurricanes, Typhoons, and Cyclones
First image:
Multi variable line graph showing the number of three unique global weather-related disasters (floods, extreme weather events, and landslides) over the fifty year period from 1969 to 2019. Each variable is plotted alongside a dotted line running straight from the 1969 number to the 2019 number, so show the increase over time. There is little variation from the average in the number of landslides (22) over the period. Extreme weather events (85) show an increase over time, showing that more of these events happened in later years. Flooding (170 events) shows the greatest increase in events, especially in more recent years. As noted in the text with this article, extreme weather events are more frequent, more intense, and last longer, compounding the damage they cause.
Snowfall and Melting Arctic Ice

Marine Heat Waves
First image:
Bar chart shows the length of the Marine Heat Waves for each of the listed major oceans over the last 10 years, and for comparison also shows that recorded marine heat waves from 1980 to 2010 totaled between 10-50 days. The ocean with the highest marine heat wave incidence (at 357 days) occurred in the Northeast Pacific between 2013 and 2015. The Southern Ocean had 183 days of Marine Heat waves, the Tasman Sean had 175 days in 2015 and 2016, and Western Australian was 101 days in 2011. Rounding out the chart are the Indo-Australian Basin (2016) with 90 days, the Southwest Atlantic (2017) with 82 days, and the Northwest Atlantic (2012) with 57 days.
Extreme Precipitation
First image:
Bar graph shows the worldwide increase in annual precipitation (measured in inches) over the period from 1901 to 2019. In the first half of the twentieth century, 80 to 90% of the years had precipitation below the global average.The range of variations was between -2” to +1.5”. From about 1950 through 2019, 20 to 30% of the years had below average precipitation, with the range of variability increasing to -2” to +4”.
The remaining years are all above average with two points worth noting. The amount of the actual increase above average is significantly larger (up to double in some years) than in the first half of the century, and that there are many groupings with five or more consecutive years of above average annual rainfall. Intense rainfall events in a single region or country do create these world wide impacts. The article notes that flash floods, deaths, and loss of property and livelihoods result. What else can you envision?
Impact of Carbon Exports & Imports
First image:
Bar graph shows the distribution of carbon exports and imports across nations. The USA, Japan, and the UK are the three largest importers of carbon. Only six nations are listed as exporters of carbon. China is the largest exporter of carbon by far, with Russia, India, and South Africa next in line, followed by Iran, Ukraine, and Qatar.
Soil Loss

Population Growth
First image:
Line graph that compares how the world fertility rate (live births per woman) have changed since 1950 through today and as forecasted through 2099. There are three lines, one for the annual average of low income countries, one for the annual average of high income countries, and one for the average of the world. Low income countries not only had the highest initial historic birth rate (6.3), but it actually rose slightly for a period of maybe 3 decades before it began to fall. The fertility rate of these low income countries is expected to continue to fall slowly but at its expected value of 2.1 at the end of the 21st century, it will likely remain above both the world average and that of high income countries. The high income countries had a fertility rate of 3.0 live births per woman in 1950, and while it remained flat for 10-20 years, it started to drop quickly and is expected to stay around 1.8 through the end of the 21st century.
Second image:
Stacked line graph that shows the worldwide population growth from 1.5 Billion in 1960 to a projected 10.9 Billion in 2100. The graph shows the cumulative global population in a stacked manner to show how Asia, Africa, North America, Europe, South America, and Oceania contribute to that total.
The first region that is shown as the base of the graph is Asia. Initially it had a very large rate of increase in population from 1960 to 2020, but the rate is slowing down and the population total of Asia is expected to drop about mid century. The population history of Africa is layered on top of Asia. Starting with a smaller initial population, and the fastest rate of growth, the population in Africa is expected to surpass that of Asia by 2100. North America, Europe, South America and Oceania are layered on the chart above Africa, and contribute a consistent portion of the worldwide population through 2100
Wildfires
First image:
Map of the United States, including Hawaii and Alaska of course, with a black rectangle with flames covering the middle half of the continental United States. Text superimposed on black rectangle states, “Wildfires affect a yearly total of 400 million hectares of land worldwide - about half the size of the United States.”

Third image:
Line graph of Self-reported Food Waste from November 2019 through April 2021. As the pandemic swept the world and people were locked down, this measure of self-reported food waste dropped by almost 50% in April of 2020, down to 13.7% as compared to 24.1% in November 2019. It increased to 18.7% in April 2021, but food waste remains lower than before the pandemic.

Food Production and Availability
First image:
Photograph of what is believed to be a Banksy street art mural in London. The mural is on a low concrete wall at a site occupied by climate activists during London protests. The image depicts a young girl wearing a head covering, possibly hungry and in threadbare clothes.. She is kneeling in the dirt with a shovel and a small plant and is looking up towards writing on the wall. On the wall the words read "From this moment despair ends and tactics begin". The girls holds an object with an image of an hourglass in a circle, which is known as the Extinction Rebellion logo. The reader is invited to wonder, “What is she holding? Will the tiny plant near her grow? Why is food so unequally available? (To learn more about this mural, look up both Banksy and Extinction Rebellion.)
Food Price Spikes
First image:
A grocery receipt from the fictitious “Price Hikes” store, located on “Planet Earth”. Four items are listed: Maize, Rice, Wheat, and "Other crops". In place of a price for each item, instead the projected decline in growth and the projected increase in price is listed. The growth rate for maize is expected to drop by 12%, leading to a potential 90% increase in price. Similarly rice production is expected to decline by 23% with an 89% increase in price, and wheat production is expected to decline by 13% with a 75% increase in price. Other crops are expected to decline in yields by 8%, and show an 83% increase in price.
Threats to Coastal Communities
First image:
List of large coastal communities that are especially vulnerable to rising sea levels and the effects of climate change. Each city name is partially obscured by a small artistic wave. The cities listed are Tokyo, Mumbai, New York City, Shanghai, Los Angeles, Calcutta, Buenos Aires, Lagos, Bangkok, Venice, Basra, Jakarta, Rotterdam, and Ho Chi Minh.
Displaced Human Communities
First image:
Map of the world that shows the distribution of millions of people who have been or will be displaced by climate change. The artist uses circles of differing sizes that correlate to the magnitude of the population displacements in addition to the estimated value. The values shown on the image are as follows: Sub Saharan Africa 86 million, South Asia 40 million, East Asia and the Pacific 49 million, Latin America 17 million, North Africa 19 million, and Eastern Europe and Central Asia 5 million. It is notable that only North America and the Australian continents do not have expected population displacements due to climate change.
The Economics of Rising Temperatures
First image:
Table listing the projected decreases in GDP for each region in 4 different scenarios. A bar illustrates the magnitude of the decrease so the values are readily comparable. The column labeled “Paris target” shows the projected decline in GDP as ranging from 2.8% to 5.5% should the global average temperature increase less than 2 degrees Celsius. More likely scenarios show that at a 2 degree increase, GDP will decrease between 6.9% and 14.9%, and at a 2.6 degree increase, GDP will decrease between 7.4% and 21.5%. In the most severe scenario, an increase of 3.2 degrees, GDP will decline by 9.5% to 27.6%.

Carbon and the Oceans
First image:
Graphic depicting three analog clocks in a row on a wall, all with the hands showing the same time, 12 noon. The first one is a circular clock, and is labeled "clock". The second is labeled Cuckoo Clock and has a pendulum and doors that open to allow a mock cuckoo bird to emerge. The third clock on the wall looks like a cuckoo clock, but is labeled the CO2 Clock. Instead of a bird tweeting as it comes through the doors to alert, there is a small globe that pops out which is on fire. Next to it is a quote by Patrick Odler about the time to act, being NOW.
Ocean Acidity
First image:
Line graph depicting the change in ocean acidity from 1988 to present and splitting into five potential paths on how the acidity of the ocean could change over the next 80 to 100 years. The main line shows that since 1988, the acidity of the ocean has dropped from just over a pH of 8.1 to a pH of about 8.03. It may seem a small number, but a small change in pH has a big impact on the acidity and on the ecosystems of the ocean. The ocean is getting more acidic due to the CO2 it is absorbing. Other lines diverging from the main line show that by 2098 the current ocean PH could drop more but recover to above 8.0 pH. Some lines show ocean pH dropping to as low as 7.66 pH by 2098. Scientists are working to determine what the impacts of these changes might be. We know for sure that reducing CO2 in the atmosphere will have a positive impact on the oceans.
10-, 50-, 100-, and 1,000-Year Climate Events
First image:
Graphic depicting dot matrix grids of 100 dots each. Each dot matrix represents the likelihood of heat waves represented by dark dots. The first dot matrix represents the period of 1850-1900 with 10 black dots to represent the likelihood of heat waves.The next four images are the scenarios for today, with a 1°C increase in global temperature, and three possible futures expected 10 years from now (1.5°C, 2°C, and 4°C). The dot matrix representing today depicts more than double the number of darkened dots to show that the likelihood of heat waves increased to 2.8 times the 1850-1900 average. Heatwaves are 4.1 times, 5.6 times, and 9.4 times more likely 10 years into the future if the temperatures rise by 1.5°C, 2°C, and 4°C, respectively.
Second image:
Graphic depicting five dot-matrix grids of 100 dots each. The first matrix shows ten black dots amid the 90 remaining gray dots to represent the heavy precipitation days between 1850 and 1900. The next four matrices are the scenarios for today, with a 1°C increase in global temperature, and three future emissions scenarios (1.5°C, 2°C, and 4°C). Today, we are 1.3 times as likely to have a major precipitation event on land in any given year as we were before 1900. The three possible future scenarios show the likelihood increasing to 1.5 times, 1.7 times, up to 2.7 times. This means that in the worst scenario, a precipitation event could happen more often or be up to 30% wetter in the worst case scenario.
Third image:
Graphic depicting five dot-matrix grids of 100 dots each. The number of darkened dots on each matrix represents the likelihood of major droughts. The first matrix represents the frequency of droughts between 1850 and 1900. The next matrix shows the scenario for today, with a 1°C increase in global temperature which makes droughts 1.7 times more likely. Three future scenarios represented with progressively more darkened dots demonstrate that a 1.5°C increase in global temperature will make droughts 2 times as likely. A2°C increase will make droughts 2.4 times as likely. A 4°C increase will make droughts 4 times as likely. In the worst case, the droughts could be up to one standard deviation more intense in terms of soil moisture.

Graphic depicting dot matrix grids of 100 dots each. Each dot matrix represents the likelihood of heat waves represented by dark dots. The first dot matrix represents the period of 1850-1900 with 6 darkened dots to represent the likelihood of heat waves before 1900.The next four images are the scenarios for today, with a 1°C increase in global temperature, and three possible futures expected 50 years from now (1.5°C, 2°C, and 4°C). The dot matrix representing today depicts more than double the number of darkened dots to show that we are 2.8 times as likely to have a heat wave in any given year. The three alternate scenarios show the likelihood increasing to 8.8 times, 13.9 times, up to 39.2 times. The dot matrix representing the scenario of a 4°C increase in global temperature is almost completely darkened. This means that in the worst scenario, a heat wave would be likely almost every year.

What’s All This Talk About Carbon?
First image:
Image depicting the many things in our world that produce carbon emissions. There is an airplane in flight, a semi truck and a long line of cars.. There are also many electrical appliances such as a space heater, a laptop, a hair dryer, and a clothes dryer all shown connected to an electrical grid, which receives power from a coal fired power plant.
Weather vs. Climate
First image:
The sketch is of a desert, with mountains in the background. There is a snowstorm happening, and snow is accumulating on two cactus plants. Snow on cactus plants in the desert doesn't quite sound normal to me. Does it sound normal to you?
The Greenhouse Effect
First image:
Graphic depicting a small portion of a city, and the Earth's atmosphere. The sketch shows how greenhouse gasses accumulate in the atmosphere and not only reduce the amount of light from the sun, but that infrared radiation is reflected back to earth because heat and carbon dioxide are unable to escape to outer space.
How Much is a Metric Ton (Tonne)
First image:
Image depicting two different stacks of bricks. The stack on the left depicts 6,300 bricks which is approximately the weight of greenhouse gas emitted per person annually in the United States. The stack on the right depicts 400 bricks which is approximate to the 2050 goal of per person greenhouse gas emissions.

Fast Facts and Definitions
First image:
Image depicting how crude oil might have been formed. Illustrated on the left hand side as 400 million years ago, under the ocean, a magnifying glass shows seawater brimming with microorganisms. As they die, they fall to the bottom of the sea. The right hand side image shows the same ocean as 100 million years ago with sand and silt and mud on top of the decaying micro-organisms which is how sedimentary rock is formed. The decay is anaerobic and with pressure (from increasing layers of sedimentary rock) pushing down and with heat from the core of the earth, crude oil forms deep under the ocean floor.

This image is of a gas pump. The gasoline pump handle is off, and a single drop comes from the fueling nozzle, signifying that gasoline supplies will eventually run out.
Climate Change Actions From Large to Small
First image:
Infographic depicting a clipboard and a pen. The clipboard contains what appears to be a checklist of birds that someone who is bird watching or doing a population tally. Some of the birds don't have any hash marks (or tallies) next to them, indicating that none exist in this area. The significance of this image is that tracking bird populations and seeing changes in the bird population is an important part of understanding the impacts of climate change.

Infographic shows the time we spend getting to a new city using two different methods. The first, shows getting to the airport terminal, waiting for two hours for a 1 hour flight, spending another 30 minutes getting to the hub of a new city for a meeting. The total carbon that is produced for each passenger on the plane is 82 kg/passenger and it takes a total of 3 hours and 30 minutes. The second transport is using a train. The wait at the train station is only 15 minutes, a 3 hour and 30 minute train ride, which places you directly at the city center. This scenario takes only 15 minutes longer, but produces only 13 kg of carbon per passenger. The message is that every choice we make has an impact. Can you spend 15 additional minutes traveling to cut your carbon emissions for the trip by a factor of more than 6?
Role of Finance
First image:
Bar graph lists ten large banks and shows the distribution of fees earned on energy related loans between Renewable projects and Fossil fuels. The bank with the highest percentage of loans on Renewable projects is HSBC at nearly 35%, followed by Sumitomo Mitsui Financial at 31%. The bank with the lowest percentage for Renewables is Wells Fargo with only 6.1%.
Second image:
Chart showing the change in the allocation of energy sector debt from 2014 to 2020. In 2014, about 5% of the debt issued was for Renewables. In 2020, debt issued for Renewable projects neared parity with fossil fuels, but overall debt since 2014 for Renewable projects was still only a third of the total energy debt. As the total debt issued fluctuates from year to year, the distribution will be important to watch to ensure that investments are being made appropriate with climate goals.
Share of Global GHG Emissions Covered by Carbon Pricing Systems
First image:
Bar chart with years on the x axis showing the approximate share of regional participation carbon pricing systems. The chart shows that only Europe had a carbon pricing system in 2005 (covering about 5% of global emissions). Since 2012, North America, China and Other regions have implemented carbon pricing systems. The chart shows that the overall percentage of GHG emissions covered by carbon pricing has increased but only 21.5% of global emissions are covered by carbon pricing systems.
