Ten Selected 2025 Super Facts

I started this blog, superfactful, in August of 2024. The goal of my blog is to create a list of facts that are important, not trivia, and that are known to be true yet surprising, shocking or disputed by large segments of the public. I determine what is true by evaluating the evidence I find in reliable reputable sources and if a longstanding scientific consensus is available that certainly helps. In some cases, I have expertise in the subject myself, which also helps. Whether a fact is important and surprising or disputed is a judgment call. In some cases, there are polls to help me determine how surprising or disputed the fact is. I am trying to avoid trivia and click bait, and I am only focusing on what is true, important and mindboggling.

It is a project I hope to learn a lot from, and I hope others will also learn something from reading it. We are all drowning in misinformation, false beliefs and unsubstantiated assumptions. We often know and understand less than we think. I have been bamboozled in the past and I am pretty sure you have too. If this blog can spread a little bit of light, I am happy.

In 2024 I posted 25 super facts and in 2025 I posted 53. I am hoping to one day to have collected 200 super facts. I have also made 64 other kinds of posts on this blog such as book reviews for educational books as well as other fact related posts. Below are ten selected super facts from 2025. To read the full post click the links.

That Earth is round was well known long before Columbus

Super fact 28: That Earth is round, or spherical (or closely spherical) had been known for at least a couple of thousand years by the time Columbus set sail. Columbus did not set sail to prove that earth was round, and he knew it was round.

I’ve realized that this comes as a surprise to some. To read the post click here.

EV Cars Indeed Emit Less Carbon Pollution

Super fact 29: EV Cars emit less pollution than Internal Combustion Engine, even considering manufacturing, disposal and EV Cars being charged by dirty grids.

There is a lot of misinformation about EVs including that EVs are not better for the environment. To read the post click here.

The histogram graph show that if you consider construction of facilities, manufacturing of vehicle and battery, production of fuel, vehicle operation as well as disposal the total average greenhouse gas emissions from EV cars is 52% less.

Scientists Agree that Global Warming is happening and that we are the Cause

Super fact 34: Climate Scientists agree that Global Warming or if you call it Climate Change is happening, and that it is caused by us primarily because of our burning of fossil fuels. There is a long-standing scientific consensus on these two facts because the evidence is conclusive. Typically, studies show an agreement of at least 97% or 98% among climate scientists.

Polls show that most American are unaware of the consensus among climate scientists. To read the post click here.

There is almost total agreement among climate scientists that global warming, or climate change, is happening and is caused by us. To understand why, you need to know a little bit about the impressive evidence, which for all practical purposes is conclusive. Take a look at this post “Global Warming is Happening and is Caused by us

The green graph is going up slightly starting from 46% in 2009 and ending in 58% in 2023. The black graph starts at 33% in 2009 and ends in 22% in 2023. The yellow graph starts at 2% in 2009 and ends in 2% in 2023.
The green graph corresponds to “most scientists think global warming is happening (%).” The black graph corresponds to “there is a lot of disagreement among scientists (%)”. The yellow graph corresponds to “Most scientists think global warming is NOT happening (%)”. Graph taken from the Yale Program on Climate Change Communication.

Time Dilation Goes Both Ways

Super fact 38 : If two observers are moving compared to each other both will observe the other’s time as being slower. In other words, both observers will observe the other’s clocks as ticking slower. Time slowing down is referred to as Time Dilation.

Clocks slow down as you travel at high speeds. However, the person travelling think they are standing still. It is the other person who is travelling. This is confusing. To understand it click here.

Emissions of ozone-depleting gases have fallen by 99 Percent

Super fact 41 : Largely thanks to the Montreal Protocol in 1987 the emissions of ozone-depleting gases have fallen by more than 99%, 99.7% to be exact, according to Our World in Data. This has resulted in halting the expansion of the ozone holes and the reduction in emissions of  ozone-depleting gases is saving millions of lives every year.

A gigantic victory for the environment that few are aware of. To read the post click here.

Sulfur dioxide pollution has fallen by 95 percent in the US

Super fact 44 : Sulfur dioxide pollution in the US has fallen by approximately 95% since the 1970s. This significant reduction is primarily due to regulations like the Clean Air Act. Global sulfur dioxide pollution has also fallen but not as much.

Another big victory for the environment that we seldom hear of. To read the post click here.

We Exploded Thousands of Nuclear Bombs

Super fact 48 : Since 1945 we have set off more than 2,000 Nuclear Bombs corresponding to a yield of an estimated 42,000 times that of the Hiroshima Bomb.

That we have exploded these many nuclear bombs was a surprise to me and perhaps to you too. To read the post click here.

The Euler Number Math Magic

Super fact 53 : The Euler number denoted e, is an irrational number, which like the number pi is extremely important in mathematics. In addition, the relationship between the Euler number and pi; seemingly unrelated numbers, is quite amazing, especially if you throw the imaginary number: i = square root of -1 into the mix. Euler’s formula e^ix = cos(x) + isin(x), where x is degrees expressed in radians, is mind blowing to say the least. Radians means that 180 degrees is replaced by pi, and 90 degrees is replaced by pi/2, etc. A simpler special case, but equally amazing is Euler’s identity e^ix = -1, or e^ix + 1 =0. This is amazing math assuming you understand it.

One of the most amazing math facts explained. To read the post click here.

The Bermuda Triangle the Big Non-Mystery

Super fact 56 : The Bermuda Triangle mystery is a myth. There is not a higher risk of disappearances in the Bermuda Triangle. To be specific, disappearances do not occur in the so-called Bermuda Triangle, or Devils Triangle, with any higher frequency than in other comparable regions of the ocean. The “mystery” of the Bermuda Triangle is largely a manufactured one, perpetuated by sensationalized accounts that often misrepresent the facts and downplay the role of natural hazards like storms.

A surprise to the people who are convinced that there really is a mystery. To read the post click here.

Evolution is a Fact

Super fact 63 : Evolution is both a fact and a scientific theory. It is a fact that life has changed over time. This is supported by overwhelming evidence, while the theory of evolution provides a comprehensive scientific explanation for these changes, using processes like natural selection.

Yes, there are scientific facts, and that evolution is happening is an observed scientific fact. To read the post click here.

There Are Scientific Facts

Super fact 62 : Facts exist in science; a scientific “fact” is an observation of a natural phenomenon that has been repeatedly confirmed by independent observers and is accepted as true for all practical purposes.

Outside of mathematics and logic nothing is ever the final truth, not in science, and not anywhere else. However, there are facts that have been so well confirmed and are so basic that there is no reason to doubt them. Earth is not flat like a pancake, and the sun is a star, are two examples of astronomical facts. Most dogs have four legs is another fact. The speed of light in vacuum is the same for all observers is a fact in physics that is surprising if you didn’t know it before. Scientific facts are verified by repeatable careful observation or measurement by experiments or other means. It is possible that we are all living in a virtual reality, like in the movie The Matrix, and that Earth is really flat like a pancake after all, because all of reality is a dream. However, for all practical purposes, it is not the case.

This blog, super facts, deal with facts that are surprising, strange, or disputed by non-experts, and yet true because they have been verified, for example, in the case of scientific facts, by repeatable careful observation. Anyone is free to object if you think I am wrong about a fact.

My next super fact is going to be “Evolution is a fact”. Evolution is also a scientific theory, but it means something different from when you say evolution is a fact. Moreover, a Scientific Theory is not a guess, as commonly but incorrectly assumed. I am bringing this up because many people who are typically unaware of the evidence behind a fact will use arguments such as “science does not know everything”, “it is just a theory”, etc., in efforts to dismiss a well-supported claim.

I should say that this post is inspired by a Facebook post by “The Credible Hulk”, a Facebook page managed by a group of anonymous scientists opposing misinformation around vaccines, global warming, evolution and GMOs. I did not save the post, but it went something like this:

One of the commentors said : “Calling evolution a “fact” defeats your argument. The Theory of Evolution is by definition a theory not a fact. It’s the currently agreed upon hypothesis but not a fact”

What the commentor did not realize is that “Theory” in the context of science does not mean what he thought it did. I am using past tense because he got “schooled”. To his credit he did not respond with insults and neither did the Credible Hulk, which does not seem to be standard on Facebook. However, his comment illustrates something that drives scientists like those who created “The Credible Hulk” nuts, and that is the widespread lack of understanding of the difference between a guess, a hypothesis, a scientific fact, theory as used in common language and used when talking about a scientific theory.

Rather than having this discussion over at my upcoming “Evolution is a fact” post, I am making a separate post about it. I consider “There are Scientific Facts” a super fact because it is true, and yet the confusion around it and what a Scientific Theory pertains is massive, and it is an important topic.

What is Science?

Science is the process of learning about the world through systematic observation and experimentation to gain knowledge about how things work. It involves observing phenomena, forming testable ideas (hypotheses), systematic studies, conducting experiments, and collecting evidence and facts that support or refute those ideas, ultimately leading to a deeper understanding of general truths and natural laws. If an idea/hypothesis correctly predicts and explains facts, it becomes a theory, which is something that is very different from a guess.

The process of making observations, formulating testable hypotheses, conducting experiments, analyzing data, and drawing conclusions to understand phenomena and solve problems is referred to as the scientific method, and there are different types of scientific methods. Some involve experiments, other involve analysis historical artifacts or existing data. Objectivity, reproducibility, falsifiability, and predictive power or problem solving are essential.

What is a Scientific Theory?

When people hear the phrase “evolution is a theory,” many mistakenly assume it means evolution is just a guess or speculation. In science, however, a theory is far more than a guess. A scientific theory is an explanation of an aspect of the natural world that can be or that has been repeatedly tested and has corroborating evidence in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. In other words, it is a well-tested, comprehensive explanation of natural phenomena, supported by an extensive body of evidence.

The evidence for evolution is both vast and compelling. It is not just the massive fossil record, it is in DNA, anatomy, there’s geographic evidence, and evidence from dozens of other scientific fields, not to mention that evolution is directly observable. There is a Theory of Evolution, that is the well supported explanation for evolution, or evolution by natural selection. There is also “Evolution is a fact” referring to, for example, the fact that we can directly observe it. It is true for all practical purposes, and that does not mean that evolution stops being a scientific theory as well as a fact.

Afterword

Even though science is constantly evolving and our knowledge is evolving and sometimes our understanding and scientific theories on a topic needs to be updated, scientific facts exist. Some scientific facts are extremely unlikely to change. For example, Jupiter has multiple moons, galaxies exist, global warming is real and is caused by us, and evolution is a fact. Before you decide to dismiss such a fact make sure you know what “theory” means in science, and most importantly educate yourself on the relevant evidence. There might be a whole lot more than you imagined, and you may discover that the evidence you thought was contrary is not evidence.

You often hear “science does not know everything”. That’s true. If science knew everything it would stop. However, the collective knowledge created by science is enormous and as individuals we know next to nothing. So be humble and learn from scientific evidence presented by reliable sources.

What change, big or small, would you like your blog to make in the world?

I have two blogs, Leonberger Life and this one called Superfactful.

Leonberger Life feature amusing and heartwarming stories about our late Leonberger dog Bronco, as well as other Leonbergers. It also has a lot of information about the Leonberger breed, the history, care, training, Leonberger organizations, etc. I also wrote a Leonberger book, which I am featuring in the sidebar. With my Leonberger Life blog I want to spread information about the Leonberger breed, a rare, large, furry, friendly and fun dog breed and also bring attention to my book The Life and Times of Le Bronco von der Löwenhöhle, stories and tips from thirteen years with a Leonberger.

The goal of Superfactful, which is this blog, is to create a long list of facts that are important, not trivia, and that are known to be true and yet are either disputed by large segments of the public or highly surprising or misunderstood by many. I call these kinds of facts Super facts because they could potentially be very impactful on how we view the world.

Humans have accumulated an enormous amount of knowledge. Science does not know everything, but it knows a lot. The same cannot be said for us as individuals. We know next to nothing and harbor a lot of false beliefs. I think that is pretty much true for all of us, including me, but we may not know it. With this blog I am trying to correct some of that, at least regarding important facts. In addition, along the way, I am hoping to learn a lot myself and have some of my own false beliefs corrected.

In short, the change I would like to make in the world with my blog is to correct as many false beliefs as possible and educate my readers, and myself, about facts that are both important and mind blowing.

What is a Super fact?

A super fact is:

  • An important fact but it can be simply stated.
  • Very surprising, shocking, widely disputed, misunderstood, or mind-blowing.
  • Yet it is true with a very high degree of certainty.

The first two criteria are subjective. The last criteria can be determined from longstanding scientific consensus, my own expertise and education (valid for just a few topics), agreement between multiple reliable online or offline sources such as agreement among research papers, reputable scientific organizations, NASA, NOAA, Pew Research Center, Our World in Data, etc. I should say I also link to less academic sources such as Wikipedia, but I do not solely rely on them.

You can read more about how I choose super facts here. Also, I am open to challenges based on good data (not opinions), as well as questions. With that I don’t mean that you cannot give your opinion in a comment. I just won’t update or remove a super fact based on an opinion. In addition, I am happy to receive suggestions for super facts. I am trying to collect a few hundred super facts and need all the help I can get. In the end I want to pick the 100 best ones. I might use a poll for that.

Sometimes a super fact involves doing myth busting of a popular myth and sometimes a super fact is stating something that is well known but disputed by many. In these cases, the evidence is likely to be conclusive, but the fact is still disputed by those who don’t know much about the evidence, or don’t want it to be true. In this case, I will include a substantial amount of evidence, and it might be lengthy. People get bamboozled all the time, and that includes me. It is not easy to admit that you have been bamboozled. You can read about my own experiences with that here.

Examples of Super Facts

At the time of posting this I have made plans for 150 super facts and so far, I have posted 54. I will post a lot more. Below I am listing a few of my first 54 super facts.

Superfact 5 : Two events may be simultaneous for some but not for others. Click to visit post.

Two events may be simultaneous for some but not for others. This means that two events that are simultaneous to an observer may happen at different times to other observers. If two lamps A and B turn on at the same time according to observer #1, lamp A may turn on first for observer #2, and lamp B may turn on first for observer #3. All three observers are correct because time is relative.

The picture shows three pairs of lamps and three people. The setup is used to show three situations.
Amy is traveling at a high speed to the left compared to two lamps A and B. Alan is standing still compared to the lamps. Adam is traveling at a high speed to the right compared to two lamps A and B. Alan turns on the lamps at the same time. After considering the travel time of the light she sees, Amy concludes that lamp B turned on first. After considering the travel time of the light he sees, Adam concludes that lamp A turned on first. I should add this non-simultaneity can only happen if the lamps are separated by a distance.
Superfact 7 : Poverty and child mortality has been sharply reduced worldwide. Click to visit post.

Extreme poverty as well as child mortality has been sharply reduced the world over. The countries that are the worst-off today are still better off than the countries that were doing the best at the beginning of the 19th century. Over the last 20 years extreme poverty and child mortality have continued to decline sharply.

Superfact 25: Global Warming is Happening and is Caused by us – click to visit post.

Global warming is happening. Or if you call it Climate Change or Climate Disruption is indeed happening. And it is happening very fast. We also know that it is caused by us primarily as a result of our burning of fossil fuels. There is a long-standing scientific consensus on these two facts because the evidence is conclusive. Check the evidence in the post.

Superfact 28: That Earth is round was well known long before Columbus – click to visit post.

Climate change worsens wildfires in the US

Super fact 52 : Climate change, including increased heat, extended drought, and a thirsty atmosphere, has been a key driver in increasing the risk and extent of wildfires in the United States, particularly the western United States during the last two decades. The number of Wildfire acres burned in the United States has significantly increased even though the number of wildfires has not. Another important factor is forest management.

The graph consists of blue bars corresponding to a year starting in 1983 with the last bar being 2020. The bars show the number of million acres burned per year in the US. In 1983 and 1984 the bars show between 1 and 2 million acres burned. The following three years more than 2 million acres were burned. From 2015 to 2020 the number of acres burned annually is between 5 and 10 million acres | Climate change worsens wildfires in the US
Wildfire acres burned in the United States. Number of acres of wildfire burned in a given year in the United States. This is shown from 1983 onwards, when consistent reporting began. Data source : National Interagency Fire Center (NIFC). Presented by OurWorldinData/natural disasters.

To some people this does not come as a surprise. However, due to the complexity of the issue combined with political spin, this is a surprise to me, or even something they refuse to believe. I’ve come across many people who are surprised to hear that there really is a connection between climate change and wildfires in regions of the world which are getting dryer and hotter due to climate change. There are also others who are surprised to hear about the complex picture and the importance of good forest management. In any case, since it is a surprising fact to many, and an important fact, I consider it a super fact.

As super fact 52 above states, Climate change is a key driver in the worsening of wildfires in the US, particularly in the American West. A 2016 study published in PNAS found that human-caused climate change caused over half of the documented increases in fuel aridity since the 1970s and doubled the cumulative forest fire area since 1984. I can add that we know that Climate Change, or if you call it Global Warming, is Happening and is Caused by us, primarily due to our burning of fossil fuels. I can also add that Scientists Agree that Global Warming is happening and that we are the Cause.

Wildfires and the Complex Statistical Picture

In general, you can’t look at wildfire statistics and draw conclusions without considering the context. Below are some considerations.

  • Wildfires are not started by climate change or poor forest management. They are started by lighting, falling powerlines, campfires that are not properly put out, and sometimes by arson. That doesn’t mean that climate change and poor forest management does not increase the risk and extent of wildfires.
  • Research organizations such as NOAA recognize that wildfire is a natural part of the western US ecosystem. However, climate change is significantly exacerbating the problem by creating conditions more conducive to intense and widespread wildfires.
  • Suppression of fire in certain ecosystems may in fact increase the likelihood that a wildfire will occur.
  • There are wildfires started intentionally to prevent future wildfires.
  • In the past, forests evolved with frequent, low-intensity fires that helped clear out underbrush. They can have ecological benefits. Therefore, the number of wildfires may not have increased over the last 100 years.
  • Local conditions and forest management have evolved through time complicating the wildfire statistics around the world.
  • In the past reporting was not always consistent.

That does not mean that we don’t know whether climate change worsens wildfires or not. Research organizations such as NASA, NOAA, NOAA (again), NOAA on LA fires , Ohio University, are all in agreement on the fact that Climate change has been a key driver in increasing the risk and extent of wildfires in the United States. Other organizations such as AccuWeather, Texas 2036, the Nature Conservancy, IFAW, American Progress, and the New York Times concurs.

Fix Our Forest Act

Climate change is a huge problem that is going to take decades to tackle and the whole world needs to be involved in that effort. However, we can quickly address wildfires here in the US, especially the American West by addressing the other half of the problem, forest management. There is currently a bill in congress called the Fix Our Forest Act that does that. It streamlines and enhances forest management based on the science. In the house of representatives, it has the number H.R.471 and in the Senate it is S.1642.

I was recently in Washington DC to do volunteer lobbying for these bills. You can read about it here.

Developed nations have successfully reduced carbon emissions

Super fact 42 : The developed nations (rich countries) have reduced their carbon emissions since the 1990’s despite continued GDP growth, even if we take offshore production into account. In addition, many developing countries have succeeded in reducing their emissions as well. Other fast-growing developing countries have flattened or at least slowed their increase in carbon emissions. Many countries have decoupled economic growth from CO2 emissions. In other words, we do not need to increase carbon emissions or burn more fossil fuels to grow the economy.

This is good news as well as a surprise to many people who falsely believe that to grow the economy (grow GDP) you need to burn more fossil fuels and an increase in carbon emissions is inevitable if you want to grow the economy. The data shows otherwise. This is important news that is difficult to believe in for many people. It is a super fact.

Carbon Emissions and GDP

In the past carbon emissions were strongly correlated with national wealth. The wealthier a nation was the higher its carbon emissions were and as the economy grew so did the carbon emissions. This has not been true since the 1990’s. The developed nations of the world have continued growing their GDP whilst reducing their carbon emissions.

You may think that the reason is that we shipped much of our manufacturing overseas and that if you consider the consumers in the importing country responsible for the overseas emissions this decoupling of GDP and emissions would disappear. But you would be wrong. Even if you make the consumers in the importing country responsible for the emissions during production in the exporting country the emissions have gone down. One example taken from this article in Our World in Data is the United Kingdom.

In the graph below for the UK the GDP (adjusted for inflation) grew by 53.26% between 1990 and 2023 and the emissions were reduced by 57.66%. If make UK consumers 100% responsible for the emissions in China and India, etc., caused by the production of goods imported to the UK the reduction until 2022 was 38.59%. That is not as much but it is still impressive and demonstrates the decoupling between GDP growth and carbon emissions.

The graph shows three plotted graphs, a dark blue one showing GDP per capita, a light blue one showing UK carbon emissions per capita and a red one showing trade adjusted carbon emissions per capita. The GDP graph is increasing by more than 50% over 33 years and the CO2 emissions per capita graph is decreasing by almost 60% and the trade adjusted carbon emissions decline by almost 40% | Developed nations have successfully reduced carbon emissions
Data source: Data compiled from multiple sources by World Bank (2025); Global Carbon Budget (2024); Population based on various sources (2024). Note: GDP per capita is expressed in international dollars at 2021 prices. Graph taken from Our World in Data.

The text in the graph above is difficult to read so I’ve copied it below in larger text:

  • Consumption-based emissions: Consumption-based emissions are national or regional emissions that have been adjusted for trade. They are calculated as domestic (or ‘production-based’ emissions) emissions minus the emissions generated in the production of goods and services that are exported to other countries or regions, plus emissions from the production of goods and services that are imported. Consumption-based emissions = Production-based – Exported + Imported emissions.
  • Fossil emissions: Fossil emissions measure the quantity of carbon dioxide (CO2) emitted from the burning of fossil fuels, and directly from industrial processes such as cement and steel production. Fossil CO2 includes emissions from coal, oil, gas, flaring, cement, steel, and other industrial processes. Fossil emissions do not include land use change, deforestation, soils, or vegetation.
  • International dollars: International dollars are a hypothetical currency that is used to make meaningful comparisons of monetary indicators of living standards. Figures expressed in constant international dollars are adjusted for inflation within countries over time, and for differences in the cost of living between countries. The goal of such adjustments is to provide a unit whose purchasing power is held fixed over time and across countries, such that one international dollar can buy the same quantity and quality of goods and service no matter where or when it is spent. Read more in our article: What are Purchasing Power Parity adjustments and why do we need them?

Below is the same type of graphs for the United Kingdom as well as France, Germany, Sweden, United States and Finland. The numbers for these countries are as follows:

  • United Kingdom: GDP growth 53.26%, CO2 emissions reduction 57.66%, trade adjusted CO2 emissions reduction 38.59%.
  • France: GDP growth 39.74%, CO2 emissions reduction 40.64%, trade adjusted CO2 emissions reduction 28.82%.
  • Germany: GDP growth 49.04%, CO2 emissions reduction 46.72%, trade adjusted CO2 emissions reduction 33.95%.
  • Sweden: GDP growth 56.00%, CO2 emissions reduction 48.45%, trade adjusted CO2 emissions reduction 34.75%.
  • United States: GDP growth 68.05%, CO2 emissions reduction 29.25%, trade adjusted CO2 emissions reduction 17.04%.
  • Finland: GDP growth 45.69%, CO2 emissions reduction 50.54%, trade adjusted CO2 emissions reduction 42.79%.

Note these are emissions reduction numbers per capita (growth for GDP) not carbon emissions per capita. For example, the United States has three to four times larger carbon emissions per capita as, for example, Sweden or France.

All these graphs show the same trends as the UK graph.

Many Countries Have Reduced Their Carbon Emissions

However, the story does not end with these six countries or even with the developed world. The 30 graphs below all demonstrate significant reductions in carbon emissions as GDP is growing, demonstrating a decoupling between GDP growth and carbon emissions. Note that Azerbaijan’s GDP grew by 93% as its carbon emissions was reduced by 7% (all carbon emissions below are adjusted for trade).

This is 30 small graphs featuring a blue and red line. The blue line shows GDP growth since 1990 and the red line carbon emissions since 1990. All blue lines point up and all red lines point down | Developed nations have successfully reduced carbon emissions
Data sources: Global Carbon Project & World Bank. There are more countries that achieved the same, but only those countries for which data is available and for which each exceeded 5% are shown. The graphs are from Our World in Data <<Link-1>>. All carbon emissions in the graphs above are adjusted for trade.

The World’s Carbon Emissions Per Capita Has Flattened

World GDP per capita has increased by 83.54% since 1990 while carbon emissions per capita have grown by 9.48%. That may not be as impressive but note two things. That is still a decoupling between economic growth and if you look in the graph, you’ll see that carbon emissions were higher in 2008 to 2019. The curve has flattened and gone down a bit. Global Warming caused by our burning of fossil fuels may be the greatest environmental challenge in recorded history, but we are slowly and steadily turning things around. We are not doing it fast enough to avoid major damage to our eco systems and perhaps civilization, but we are still turning things around.

The graph shows two graphs. The dark blue one shows GDP growth per capita and the light blue the carbon emissions per capita.

China’s Carbon Emissions

One reason the world’s carbon emissions per capita have not been reduced much despite the fact that so many countries have reduced their emissions is that the world’s largest emitter China, has grown their carbon emissions steadily since 1990. Between 1990 and 2023 China’s GDP per capita (and adjusted for inflation) grew by 1,245.28% and their emissions grew by 288.43% per capita. Remember that China has 1.4 billion people so that is a big carbon blast for the world.

However, before you blame China too much remember that China’s carbon emissions per capita is less than that of the United States and that of many other developed countries, and the country with the largest cumulative carbon emissions is the United States. China’s economic growth has been immense, and its immense population of 1.4 billion people explains its huge impact on the world’s carbon emissions.

Fortunately, it now appears that China’s emissions have finally peaked.
