Orbital Cycles are not the Cause of the current Global Warming

Superfact 122: We know that the current global warming, or if you call it Climate Change, or Climate Disruption, is caused by us primarily because of our burning of fossil fuels. It is not “natural causes”, and it is not orbital cycles, so called Milankovitch cycles. These orbital cycles include changes in orbital eccentricity, axial tilt, and axial precession.

Three illustrated orbital cycles. On the left orbital eccentricity, in the middle is the axial tilt and on the right axial precession.

The evidence that the current rapid global warming is chiefly caused by our burning of fossil fuels is extensive and for all practical purposes conclusive. One of the steps towards understanding this evidence is understanding why no known natural cause of climate change can explain the current warming, and that includes orbital cycles. Therefore, this post is just one small step towards preparing you for the evidence that the current rapid global warming is chiefly caused by us. However, there is a lot of disinformation around this specific topic.

Very briefly; Earth’s orbital cycles, called the Milankovitch cycles are largely responsible for the ice ages, but they are not responsible for the current warming because the current warming is too rapid for the orbital cycles to be the cause, and the way the warming is happening is incompatible with how a warming caused by Milankovitch cycles would have happened. In addition, according to the Milankovitch cycles we should be cooling, not warming.

I am considering this a super fact because a lot of people have been fooled by the disinformation on this topic, and there is also a lot of gaslighting from less than reputable organizations and from politicians. They have bamboozled a lot of people. About 15 years ago, I was bamboozled by the disinformation myself. That was before I took the time to try to understand the topic. Understanding a topic, and understanding the evidence makes all the difference, and that is why climate scientists are near unanimous the world over that climate change / global warming is both real and caused by us.

Ask yourself, why would the climate scientists and the atmospheric physicists around the world, including scientists at NASA and NOAA, not investigate orbital cycles and other natural causes for climate change as a possible cause for our current warming? They are the experts on orbital cycles and past climate after all. We know that orbital cycles are not the cause of the current global warming, and this is important to know. Therefore, I think it is a super fact.

What Are Orbital Cycles?

One type of important type of climate forcing that’s been the cause behind the multiple ice ages that we’ve had over the last two million years are earth’s orbital cycles, or the Milankovitch cycles. There are primarily three orbital cycles, orbital eccentricity, change in axial tilt, and axial precession. Could they explain the current warming? No, they can’t because they are too slow, we are currently in a cycle that should be cooling the planet, and the way orbital cycles would warm the planet if they were responsible for the warming is very different from what we are witnessing.

Changes in Eccentricity

Earth’s orbit is not a perfect circle. Earth’s orbit varies from nearly circular to slightly elliptical and this change can cause climate change. This shift in Earth’s orbit takes place over periods of about 100,000 and 400,000 years. Click on the video from NASA below for an illustration of Earth’s eccentricity.

Changes in Obliquity (Tilt)

The angle Earth’s axis of rotation is tilted as it travels around the Sun is known as obliquity. Obliquity is why Earth has seasons. Over the last million years, it has varied between 22.1 and 24.5 degrees with respect to Earth’s orbital plane. The greater Earth’s axial tilt angle, the more extreme our seasons are. In addition, a larger tilt angle favor periods of deglaciation. The changes of Earth’s obliquity have a period of 41,000 years. Click on the video from NASA below for an illustration of the changes in obliquity.

Axial Precession (Wobble)

Earth wobbles slightly as it rotates, like a slightly off-center spinning top. The axis of Earth’s wobble changes slowly and is called axial precession. The corresponding cycle spans 25,771.5 years, or approximately 26,000 years. Click on the video from NASA below for an illustration of the changes in axial precession.

Video Explaining Earth’s Orbital Cycles

The video below from PBS gives an explanation and overview of earth’s three orbital cycles.

Orbital cycles are far too Slow to Cause the Rapid Global Warming Happening Today

The changes in Earth’s orbit and tilt operate over 20,000+ to 100,000-year periods, making Orbital Cycles unable to drive the sharp temperature spikes seen in a single century.

The graph shows the temperature since the last ice age. There is a maximum temperature about 6,000 years ago, then a cooling and then a sharp uptick in temperature.
Global temperature going back twenty thousand years, a hockey stick graph. Notice the stable temperature during the last 10,000 years, coinciding with the development of human civilization, and also notice the sudden sharp increase at the end. Orbital cycles can’t explain that, and it certainly does not look natural.

Orbital Cycles Predict Slow Cooling, not Rapid Heating

About 6,000 years ago Earth’s temperature was a bit warmer than it is today largely due to the climate fluctuations caused by orbital cycles. The warm period in the beginning of the Holocene epoch is referred to as the Holocene climatic optimum. Natural causes for climate change caused Earth’s temperature to slowly cool off until the recent very sudden uptick in average global temperatures.

The graph shows wild swings over the last 50,000 years and then a very sharp uptick at the end, which as indicated in the graph is caused by us.

Below is a video that explains in greater detail why orbital cycles cannot explain the current warming. You can also read more about it here.

The Cooling of the Upper Atmosphere Tells Us the Current Warming is not Caused by Orbital Cycles or the Sun

Yes, the cooling of the upper atmosphere (specifically the stratosphere above the troposphere) is a key sign that current global warming is not caused by Milankovitch cycles or changes in the sun. Instead, observations show a warming lower layer (troposphere) and a cooling upper layer, which is the exact “fingerprint” of human-caused greenhouse gases. Other evidence that the warming is caused by greenhouse gases and not orbital cycles or the sun is the distribution of the warming across the globe and over time.

A Couple of Videos

The video below is a short one-minute overview of the causes behind global warming.

The video below from NASA is a bit longer, 13 minutes, but it gives a more detailed overview. Click here to see the page from where this is coming from.

Conclusion

We know that Orbital Cycles are not responsible for the current rapid global warming because Orbital Cycles operate on tens of thousands of years or hundreds of thousands of years, not a couple of centuries.

We know that Orbital Cycles are not responsible for the current rapid global warming because the effects of Orbital Cycles are slowly cooling Earth, not warming it.

We know that Orbital Cycles are not responsible for the current rapid global warming because if it was orbital cycles (or the sun) the upper atmosphere would not be cooling and the temperature increases would be distributed differently across Earth and distributed differently with respect to time.

The Mysterious Vanishing of Bronze Age Civilizations

Superfact 121: Between the years 1200BCE and 1150BCE (3,200 years ago) major civilizations in the Mediterranean and Near Eastern civilizations vanished or collapsed completely, notably Mycenaean Greece, the Hittite Empire, the Canaanite city-states, civilizations in eastern Libya, Balkans, and Babylon suffered a severe political decline and eventual fall during the Late Bronze Age collapse. Other civilizations such as the Assyrian empire and Egypt survived the Late Bronze Age collapse but emerged severely weakened.

The Mediterranean and Near Eastern civilizations were powerful, important and wealthy, and their sudden collapse is one of the most consequential and mysterious events in history that ended in a dark age that lasted several hundred years, including the Greek Dark Ages, which lasted from c. 1200 BCE to c. 800 BCE.

The reason for the late Bronze Age collapse is being debated but climate change, droughts, and invasions by the so called Sea Peoples are considered to be major reasons. The Trojan war, which is mostly fiction occurred around 1200 BCE. If you watched the recent 2026 movie the Odyssey, you probably notice the frequent references to the Sea Peoples. One of the Sea Peoples was the Philistines. If you want to take a deep dive into the late Bronze Age collapse, click here, or here.

Most of us know about the collapse of the Roman Empire around 400-500 AD and perhaps the fall of the Byzantine Empire in 1453 AD, but the late Bronze Age collapse may come as surprise to many despite it being so consequential, at least I was very surprised when I first learned about it. It was not just civilization collapsing but many at the same time. The collapse is also mysterious and shrouded in mythology. That is why I consider it a super fact.

The Collapse of Mycenaean Greece

The collapse of Mycenaean Greece stands out. No other part of the Eastern Mediterranean suffered a civilizational setback quite as intense as in Greece. I think most of us are aware that after the Mycenaean Greece came other periods in Greece’s history, the Greek Dark Ages, the Archaic period, and classical and Hellenistic periods, Alexander the Great, Plato, Aristotle, etc.

I learned in school that there was a Dorian invasion of Greece that displaced its original population and this led to the Greek Dark Ages before a rebirth of Greek civilization. This is most likely not true. The Mycenaean Greeks were not replaced by modern Greeks; they were the ancient Greeks. What likely happened was that climate change and drought resulted in crop failures, which in turn resulted in people movements and a range of invading peoples around the Mediterranean and the Near East. This is what may be remembered in Homer’s account of the Trojan War.

Super Rich

Superfact 120: The amount of wealth owned by the billionaires is roughly double as much as the poorest half of the world’s population. The amount of wealth owned by the 12 richest billionaires is more than the wealth of the poorest 50% of the world’s population. The richest 1% of the global population owns approximately 38% to 45% of the world’s total wealth.

There are at the moment of this writing 3,428 dollar billionaires in the world worth 20.1 trillion dollars together. For comparison the poorest 50% of the world’s population holds between $9 trillion to $12 trillion dollars of wealth (about half). According to this report the amount of wealth owned by the poorest half of the world is less than the amount owned by just the 12 richest billionaires. By the time you read this the numbers have probably changed (likely upwards). You can also read more in Wikipedia.

I am specifying that it is in dollars and not let’s say in the Iranian Rial. With respect to the Iranian Rial, I am also a billionaire, and you are probably too (if you own a phone or computer). One dollar can buy roughly 1,300,000 to 1,600,000 IRR. You just need $700 to be a billionaire in the Iranian Rial.

I should say that initially I was just going to list interesting statistics about the super-rich. However, I found myself surprised by the statistics, and I am sure I am not the only one. Therefore, I picked a couple of facts I decided super facts.

Wealth share of the richest 1%

The richest 1% of the global population owns approximately 38% to 45% of the world’s total wealth, which is more than what 95% of humanity own according to Oxfam. The richest 1% of the global population is not about billionaires, it may very well include you and me. Our World in Data has collected and analyzed the statistics for each country in the world. The top richest 1% in the United States own 34.78% of the wealth in the United States. The top richest 1% in Russia own 48.99% of the wealth in Russia. The top richest 1% in Sweden own 27.49% of the wealth in Sweden. The top richest 1% in the Netherlands own 13.98% of the wealth in the Netherlands. See the graphs below from Our World in Data.

As you can see from the graphs below the extreme inequality is nothing new. Europe was extremely unequal in the 19th century. The 1% owned 58.01% of the wealth in 1900. The United States was relatively equal in 1978 when the 1% owned 21.79% of the wealth. Russia became very unequal since 1995. I suggest that you play around with the graphs yourself .

High Wet-bulb Temperatures the Mass Killer in Heat Waves

Superfact 119: Heat waves are becoming significantly more frequent, intense, and longer-lasting globally due to human-caused climate change. The combination of a high temperature and humidity can create a high so called wet-bulb temperature that you cannot survive unless you can find a way to cool down. High humidity and heat can make it impossible to cool off through sweating, which rapidly leads to heatstroke. It is estimated that this kills about 500,000 people annually.

Imagine that it is a hot and humid day, but you want to go for a hike for a few hours. It is 104 degrees (40 Celsius) and humid, but you don’t know how humid. You are concerned about the Wet-bulb temperature. You use the Wet Bulb calculator and you find out that a relative humidity of 70% will yield a Wet-bulb temperature of 35 Celsius, which is deadly. You won’t survive that. A relative humidity of 45% will yield a Wet-bulb temperature of 30 Celsius, which is very dangerous but survivable for a healthy person.

How would you find out how big the risk is? The wet-bulb thermometer above is in Japanese and pretty cryptic but Amazon has wet-bulb thermometers that you can easily understand. Here is another one also on Amazon. I promise, I am not trying to sell Web-bulb thermometers for Amazon. I am just pointing out that we may need to start paying attention to Wet-bulb temperatures and perhaps buying these products as heat waves are becoming significantly more frequent, more intense, and longer-lasting due to our burning of fossil fuels.

The graph shows the increased risk for 10-year heavy rains, 10-year droughts, 10-year heat waves and 50-year heat waves at differently increased global average temperatures, +1.0 Celsius, +1.5 Celsius, +2.0 Celsius, +3.0 Celsius, +4.0 Celsius,
Large increases in both the frequency and intensity of extreme weather events (for increasing degrees of global warming) are expected. RCraig09, CC BY-SA 4.0 https://creativecommons.org/licenses/by-sa/4.0, via Wikimedia Commons.

I should say that the Wet-bulb temperature of 95 Fahrenheit / 35 Celsius is more of an upper limit for survivability, like a suicide temperature. Wet bulb temperatures below 35 Celsius can also be very dangerous, at least for some people. As mentioned, excess heat and humidity kill about 500,000 people annually. You can read more here or here.

I was first made aware of the Wet-bulb temperatures when I read a science fiction novel focused on climate change, a so called Cli-Fi novel, the Ministry for the Future by Kim Stanley Robinson. It was a dystopian novel with the premise that 20 million Indians died because the Wet-bulb temperature became deadly in a large area in India, and not many people had air conditioning. Also, animals including wildlife and cattle died because, well obviously they did not have air-conditioning.

What followed was international crises, revenge and terrorism by the survivors against those whom they believed to be most responsible for our global warming / climate change, and desperate geo-engineering solutions to cool the planet. At first, I thought it seemed exaggerated but then I learned that dozens of places have already reached deadly Wet-bulb temperatures. Hopefully, a catastrophe like that will never happen but it is not entirely implausible.

The existence of the Wet-bulb temperature scale was a surprise to me. I knew that if you got locked into a Sauna for a long time you would not survive. Accidents that like that have happened in Sweden where I grew up. I did not know that the same thing could happen at natural temperatures. It made me realize that the more frequent, intense, and longer-lasting heat waves we are experiencing is a serious issue. I consider this to be a super fact because it is a true and important fact that many are unaware of.

What is the wet bulb temperature?

The wet bulb temperature is the lowest temperature to which a body can cool down through the evaporation of water (like sweating). It is measured using a thermometer covered in a water-soaked cloth. Because evaporation absorbs heat, the wet bulb temperature is lower than the actual air (dry bulb) temperature. When it is dry outside, sweat evaporates rapidly, keeping you comfortable. When it is humid, the air is already saturated, making it difficult for sweat to evaporate.

The humidex index, real feel and the wet-bulb all take both temperature and humidity into account, but Wet-bulb is focused on the body’s ability to cool down and is a safety measure. For example, if the Wet-bulb temperature is 28 Celsius then a body hotter than that (a human body is 37 Celsius) can lower the temperature via evaporation (sweating). So, a Wet-bulb temperature of 28 Celsius is not a problem (in that regard).

However, if the Wet-bulb temperature is 37 then the human body cannot use evaporation to cool down. Sweating won’t do anything. You’ll overheat and die. A Wet-bulb temperature of 35 is close enough to 37 for your evaporation system to fail and you’ll die. Basically, humidex is about feel, and Wet bulb about whether the body’s cooling system will work.

Our emissions seemed to have peaked, what is the worry ?

I have stated in other posts that thanks to the expansion of renewable energy our carbon emissions have taken a different path lately and that it looks like our emissions have started to go down, so what is the worry? It is important to understand that the average temperatures are not directly tied to our emissions but to the total amount of greenhouse gases in the atmosphere, for example, CO2 (an important greenhouse gas) leaves the atmosphere very slowly, and any level of excess CO2 emissions will keep accumulating.

Before we humans came along there was a balance, the soil, volcanoes, etc., added CO2 and roughly the same amount left the atmosphere. The so called carbon cycle. Imagine a bathtub with a drain that is slowly emptying water and a faucet adding about the same amount. Then we came along and sped up the faucet. For example, humans add roughly 60 to 100 times more CO2 to the atmosphere each year than all the volcanoes on the planet combined. Note: Our current administration is trying to censor climate science related information from NOAA and NASA, so tell me if the link in the previous sentence has stopped working.

A faucet is filling up a transparent glass bathtub with water, and a drain is emptying it but much slower.
The faucet is adding water to the bathtub faster than the drain is emptying the water, so it keeps filling up. The same is true for the CO2 in our atmosphere. Our emissions correspond to the faucet. I generated this picture with the help of ChatGPT.
Again a faucet is filling up a transparent glass bathtub with water, and a drain is emptying it but much slower. The difference between this picture and the previous is that in this picture the faucet is a bit slower than the faucet in the first picture, but still faster than the drain. | High Wet-bulb Temperatures the Mass Killer in Heat Waves
The faucet is adding water to the bathtub a little bit slower than in the previous picture but still faster than the drain is emptying the water, so the bathtub still keeps filling up, but a little bit slower. That is why the problem with heat waves will keep getting worse despite us doing a little bit better with our emissions. I generated this picture with the help of ChatGPT.

There are more than 100 million forcibly displaced people

Superfact 118: There are more than 100 million forcibly displaced people in the world, including more than 30-40 million refugees, 9 million asylum seekers, and more than 70 million internally displaced persons. The number of refugees in the world has almost tripled since the year 2000 and the number of internally displaced persons is estimated to have more than ten doubled since the year 2000.

According to Wikipedia the number of refugees is 41.6 million worldwide, 72.1 million internally displaced persons, 8 million asylum seekers and 122.6 million forcibly displaced people in total globally. The number of refugees in the year 2000 was 12,129,600 and the number of internally displaced persons in the year 2000 was 5,998,500.

According to the refugee council of Australia there were 117.8 million forcibly displaced persons in 2025 including 34.4 million refugees, 9 million asylum seekers, and 73.5 million internally displaced persons. According to Our World in Data a record 83 million people globally were living in internal displacement at the end of 2024.

I should explain that a refugee is someone who has been forced to flee their home country to escape war, violence, or persecution. A refugee who acquires a new citizenship or returns to his country stops being a refugee. An internally displaced person is an individual who was forced to leave their home or place of residence but did not cross an international border.

It should be noted that World War II was the largest forced displacement event in recorded human history. 65 million people were forcibly displaced in Europe alone according to the Imperial War Museum. The partition of India and Pakistan in 1947 resulted in 12-20 million people being forcibly displaced according to this article. The Afghanistan war resulted in around 10 million people being forcibly displaced according to this article.  Today most refugees (65%) come from just five countries Syria, Venezuela, Ukraine, Afghanistan, and Sudan.

Having tens of millions of refugees and forcibly displaced persons is nothing new. What may come as a surprise to many is first of all the size of the numbers and the fact that despite the reduction of causalities from wars in the 21st century compared to previous centuries; the refugee and forcibly displaced persons problem has grown significantly larger over the last couple of decades. Since this is an important but surprising reality, I consider it a super fact.

Where Are the Internally Displaced Persons ?

The map indicates that there are several million internally displaced persons in countries like the Democratic Republic of Congo, Chad, Sudan, Ethiopia, and Somalia. | There are more than 100 million forcibly displaced people

You may wonder how come there are internally displaced people in countries such as Japan and the United States. The reason is that natural disasters can also be a source of internal displacement. In fact, my in-laws were internally displaced persons after a tornado devastated our neighborhood in Dallas in October 2019. Notice that the Africa is where you have most of the internally displaced persons.

Where are the Refugees ?

The graph shows the number of refugees in three countries Iran, Turkey and Germany, over the period 1951 to 2024. Other than the sharp uptick for Iran in early 1990 the graphs are sharply increasing over the last 15 years.

The three countries with the most refugees are Iran (3.49 million), Turkey (2.94 million) and Germany (2.75 million). Next comes Uganda, Pakistan, Chad, Poland, Ethiopia, all Bangladesh, all with more than one million refugees. Iran has a lot of refugees because of the refugees from Afghanistan pouring into the country, and Turkey has a lot of refugees because of the refugees from Syria, and Germany has a lot of refugees because of their generous immigration and refugee policy. The big spike in the number of refugees in Iran around 1991 was due to the Gulf war and the Afghanistan war.

As for other Western countries, France has 722 thousand refugees, United Kingdom 516 thousand refugees, the United States 435 thousand refugees, and Spain 429 thousand refugees. By clicking here, you can play around with the graphs and compare all countries in the world.
