The goal of this blog is to create a list of super facts. Important facts that are true with very high certainty and yet surprising, misunderstood, or disputed by many. This blog aims to be challenging, educational, and fun, without it being clickbait. I determine veracity using evidence, data from reputable sources and longstanding scientific consensus. Prepare to be challenged (I am). Intentionally seek the truth not confirmation of your belief.
Category: Super fact
This post is about a super-fact. The goal of this blog is to create a list of facts or insights that are important and not trivia, known to be true, and yet highly surprising, shocking, amazing, or widely disputed amongst the public but not disputed among the scientists or experts in the relevant fields. However, not all of my posts are super-facts. This category distinguishes posts that are super-facts.
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.

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.
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.
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.

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.
Super fact 51 : In 1968 5,033 Americans died from a drug overdose. In 1978 5,506 Americans died from a drug overdose. In 1999 16,801 Americans died from a drug overdose. In 2022 107,941 Americans died from a drug overdose. 82,000 of those deaths involved opioids (about 76%). The number of people who died from an opioid overdose in 2022 was 10 times the number in 1999. More than half of all opioid deaths in the world were Americans despite being only 4.2% of the world population. The hardest hit demographic is white males.
Note the data in the super fact above is taken from Wikipedia, which in turn took it from CDC. However, the data across multiple sources look roughly the same (CDC / CDC, NIDA/NIH, Our world in Data, Wikipedia). I think this is a super fact. I should add that the statistics seem to have improved a little bit in 2023 and 2024.
I’ve posted about good super facts in this blog several times:
However, unfortunately there are also bad super facts, like this one.
The Severe Drug Overdose Epidemic in the US is a Super Fact
We recently went to the funeral for the young son (in his 20’s) of good friends of ours. He died from a drug overdose. The same thing happened to another friend of ours not too long ago. Despite all the talk about drugs, the war of drugs, and the “just say no campaign”, in the 1980’s I don’t remember this happening to people I knew when I was young, so I looked up the statistics. I knew we had an opioid epidemic with Fentanyl being the greatest culprit followed by Heroin. I just didn’t realize how severe it was and how American it was. This is important and shocking and the sources behind the data are reliable, which is why I consider this a super fact.
The United States Has by Far the Highest Death Rate from Opioids
If you play around with this graph from Our World in Data you will notice that the United States has a very high rate of deaths from drug overdoses, especially opioids, much higher than any other country. For example, take my home country Sweden, where 283 people died from opioid in 2021 (398 all drugs, data from IHME). Compare that with the United States, where 55,452 died from opioid in 2021 (70,893 all drugs, data from IHME). Adjust that for the population in each country you get a rate of 16.3 deaths per 100,000 inhabitants for the US and 2.7 deaths per 100,000 inhabitants for the Sweden. Sweden and the US are both open wealthy democracies in which certain opioids are legal for medical purposes but otherwise illegal. The graph below has slightly different numbers but notice that the year (2024) is different.

Some illustrative Graphics on Drug Deaths
The graphs below illustrate both the sharp rise in drug related deaths, especially opioids, as well as how hard hit the United States is compared to the rest of the world.
The population of the United States is 340 million.The population of South America is 438 millionThe population of Europe is 744 million.The population of Asia is 4,800 million.This graph shows the contribution to US deaths from specific drugs including synthetic opioids (Fentanyl), Heroin, prescription opioids, and cocaine. Notice that the vertical axis shows the death rate per 100,000 people and not the total number of deaths. Data source : US Centers for Disease Control and Prevention WONDER. Note: Opioids include prescription pain relief drugs, synthetic opioids, excluding methadone and other opioids such as heroin. The graph is taken from Our World in Data.
Super fact 50 : There are hundreds of types of beer but in general they fall into two main categories, ales and lagers, and these two categories are not differentiated based on color. The ales are not necessarily dark and lagers light. There are light colored ales and dark, even black ales. There are light colored lagers and dark and almost black lagers (Schwarzbier). The difference between ales and lagers is the type of yeast used and the fermentation temperature. Ales are typically made with top-fermenting yeast at warmer temperatures. This result is a wider range of flavors and aromas, often with fruity or spicy notes. Lagers, on the other hand, are made with bottom-fermenting yeast at cooler temperatures making them crisper and more subtle. Ales have been around for 6,000 years. The lager is a more recent invention.
I consider this a super fact, first, because even though beer is a well-known drink that a lot of us drink almost every day, a lot of people don’t know what the two basic kinds of beer are. They don’t know what an ale is or what a lager is. Even beer fans and many people who drink beer every day are often clueless about this, the most basic fact about beer. A lot of people say that they like light/blond beer or they like dark beer. In my native country Sweden, which I admit is not a true beer country, I often hear people say that they prefer “ljus öl” (light/blond beer) rather than “mörk öl” (dark beer), or the other way around, which is like saying that you like blond / light colored food rather than dark colored food. It doesn’t make sense.
This is a so called Schwarzbier that I drank some time ago. Das Schwarze a German Schwarzbier from Dinkelacker-Schwabenbräu, ABV 4.9%. Some roasted notes, sweet caramel, light flavor, a bit fizzy, somewhat thin but good enough. This is a Lager but notice a how dark it is, basically black. I did not put black dye in it. It is how they really look despite being Lagers.
I am in the process of learning Franch, and I’ve discovered that this confusion is even baked into the French language. Well as you might guess France is not a true beer country. If you use Google Translate and you type in “Lager” in the English edit box the answer you get in French is “Bière blonde”, even though French and Belgian beer that are labeled Blonde frequently are Ales not Lagers. I’ve read a lot of French language sites mentioning beer, and unless the author has some beer expertise, they make the same mistake as Google Translate. Blonde / light beer is not Lager, and dark beer is not necessarily Ale.
I had a discussion about this with one of my French teachers and despite me having talked a lot about beer in class and having previously shown him that I knew something about the topic, he had a very hard time accepting the truth. After a Google search he finally accepted the truth, but he was very surprised, perhaps even shocked.
The confusion is immense, it is worldwide, and the truth is surprising to some people. I should mention that Americans for the most part get this right. In general Americans know that Lager isn’t necessarily blonde and vice versa. They know that IPAs, which are not Lagers but Ales, typically are light colored. Perhaps because of the prominent craft beer industry in the US. I should also mention that there are also hybrid beer styles and beer styles that are hard to classify as lager or ale. More about that later.
This is Ba Ba Black Lager, an American Schwarzbier. I had sushi with this Schwarzbier.
Secondly, lagers, especially pale bland mass-produced lagers have become so common that when people taste an ale, especially if it is a little bit different, like fruity, tart, have chocolate or coffee flavors, etc., they don’t even consider it a real beer. In their minds real beer is a bland tasting lager. Never mind that we have had Ales for 6,000 years, and that Ales dominated beer drinking up to relatively modern times. Nowadays 90% of beer consumption worldwide is lagers (87% in the US), but throughout most of human history nearly 100% of beer consumption worldwide was ales.
This is an IPA called Cold War. IPAs are NOT Lagers. However, notice how light the color is. IPAs are popular in the US, which I think is one reason Americans are better educated on the difference between lagers and ales to countries that are not part of the European beer countries (Germany, Britain, Ireland, Belgium, the Czech Republic, etc.)
What is an Ale?
As mentioned, an Ale is a style of beer, brewed using a warm fermentation method. Ales are typically made with top-fermenting yeast at warmer temperatures. This result is a wider range of flavors and aromas, often with fruity or spicy notes. The word ale is an English word which in medieval England meant a drink brewed without hops (it is not what it means today). Some popular ales include IPA, Pale Ale, Stouts, Porter, Scotch Ale, and Barley Wine. Below is a more complete list of Ales. The list is from the beer advocate. Despite the 120 styles listed the list is not complete. It should be noted that I’ve added a few that were missing.

Trappist Westvleteren from Brouwerij Westvleteren (Sint-Sixtusabdij van Westvleteren) a Belgian Quadruple might be the most renowned beer in the world. I’ve had it many times and it is heavenly. However, it is very difficult to get in the US. A Quadruple is a type of Ale.Plutonium-239 from the Manhattan Project Brewing Company in Dallas, Texas. It is a strong-tasting Porter with coconut flavors. (chocolate, coconut and coffee). There is no clear definition on the difference between porter and stout, other than porters are in general milder and not as strong as stouts. From that perspective Plutonium-239 is really a stout.
Wild Ales and Sour Beers often have fruity flavors. This can be achieved by adding fruits or berries to them but often fruit flavors emerge naturally from the fermentation process, which, at least if you use wild yeast, produce esters (fruit flavors). Wheat beers often have banana or pear notes and just as for Wild Ales these flavors emerge naturally from the fermentation process (esters again). Some of the IPAs also have distinct fruit flavors, especially the New England style IPAs, but in this case the fruit flavors come from the hops.
Jester King in Texas brews a Wild Ale called Atrial Rubicite. It is a Wild Ale infused with raspberries. The fermentation process uses “wild yeast” to create a tart and fruity base but raspberries are added to enhance the fruit flavor resulting in a thick full raspberry flavor which most people describe as heavenly.
What is a Lager?
As mentioned, lagers are made with bottom-fermenting yeast at cooler temperatures making them crisper and more subtle. The word lager (German) means to storage or storeroom and used to refer to beers stored at cold temperatures. Sometime in the 15th century cold fermentation yeast emerged, and people started using it to do fermentation at cold temperatures. As time went by this form of fermentation became more popular. It was brought to the US in 1840 and between 1860 and 1870 it became the most popular fermentation process in Bohemia. As mentioned, today 90% of beer consumption worldwide is lagers.
Below is a more complete list of Lagers. The list is from the beer advocate.
Pale Lagers: American Adjunct Lager, American Lager, Czech / Bohemian Pilsner, Czech Pale Lager, European / Dortmunder Export Lager, European Pale Lager, European Strong Lager, Festbier / Wiesnbier, German Pilsner, Helles, Imperial Pilsner, India Pale Lager (IPL), Kellerbier / Zwickelbier, Light Lager, Malt Liquor.
Dark Lagers : American Amber / Red Lager, Czech Amber Lager, Czech Dark Lager, European Dark Lager, Märzen, Munich Dunkel, Rauchbier, Schwarzbier, Vienna Lager.
Specialty Lagers : Japanese Rice Lager, Chile Beer
Paulaner is a so called Festbier (or Octoberfest), which is type of Lager made especially for Octoberfest in Germany.
Finally, there are also specialty beers that are hybrids, or neither or that can be both.
Hybrid (Ale/Lager): Bière de Champagne / Bière Brut, Braggot, California Common / Steam Beer, Cream Ale.
Neither lager or ale, or can be both : Fruit and Field Beer, Low-Alcohol Beer, Rye Beer, Smoked Beer, Herb and Spice Beer, Kvass, Gruit, Happoshu, Pumpkin Beer.
That’s 120 styles of beer. I’ve had 110 beer styles. How many have you had?
Super fact 49 : The top one-meter (3.3 feet) of a typical 10 meters (33 feet) by 40 meters (131 feet) garden contains 2 kilograms (4.4 pounds) of Uranium. For comparison, the Hiroshima bomb contained 64 kilograms (121 pounds) of Uranium. Certain rocks such as Granite and Shale contain much more Uranium than soil. Uranium also exists in the atmosphere and there is 4.5 billion tons of Uranium in the ocean.
The numbers above come from the IAEA (International Atomic Energy Agency) and Stanford University . I should mention that the numbers vary depending on Geography, type of soil, etc. For example, there is much less Uranium in the soil in Florida compared to the soil in the Midwest.
This may come as a surprise to many people. Isn’t Uranium radioactive? How come we are still alive? That’s why I call this a super fact. The answer is that even though Uranium is used in nuclear bombs and nuclear reactors, it is by itself not very radioactive. You can hold natural uranium in your hand without much risk. The radioactivity from, for example, nuclear explosions come mainly from the fission process and the radioactivity from nuclear reactor waste is mainly from other isotopes created by the fission process in the reactor rather than the uranium itself.
If Uranium is not very radioactive, how come a nuclear bomb spread so much radioactivity. The answer is that the radioactivity comes from the fission process and the resulting new isotopes, not the uranium.
What Are Isotopes?
Before I explain some facts about the radioactivity and decay rate of Uranium, I should explain what an isotope is. Atoms consist of a nucleus and electrons surrounding the nucleus. In the nucleus there are protons and neutrons (and some other stuff). Neutral atoms have an equal amount of electrons and protons, which determines what kind of element it is. Hydrogen has one electron and one proton. Helium has two electrons and two protons. Oxygen has eight electrons and eight protons, etc. The number of protons/electrons is called the atomic number of the element.
The number of protons plus the number of neutrons is called the mass number. Atoms of the same element but different number of neutrons are called isotopes. Uranium-235 or U-235 has 92 protons and 235 – 92 = 143 neutrons. The number if protons/electrons determine the chemical properties of the element. The number of neutrons determines nuclear properties such as the stability of the nucleus, radioactivity, etc., as well as the weight. Therefore U-238 and U-235 are identical chemically and look and feel the same, but U-235 is more radioactive, and you can use U-235 for fission but not U-238.
This is a simplified Bohr model of the Uranium atom. There are 92 little blue balls circling a nucleus in the middle of the atom. Those are electrons. In the nucleus there are 92 protons. Those are the red balls with plus signs. In addition, there is a yellowish smudge around the protons in the nucleus. Those are the neutrons. Depending on the isotope, there are 143 neutrons for U-235, 146 neutrons for U-238 and 142 neutrons for U-234. Shutterstock asset id: 1999370450 by Patricia F. Carvalho
The decay rate of Uranium
There are three main Uranium isotopes. Uranium-234, Uranium-235, and Uranium-238. Uranium-238 is the most common. 99.28% of natural Uranium is Uranium-238, 0.72% is Uranium-235 and 0.0057% is Uranium-234. Uranium-235 is the isotope we use for nuclear weapons.
The different isotopes have different decay rates and different levels of radioactivity. The half life of a radioactive isotope is the time it takes for an isotope to decay so that only half of it is left. The half-life of Uranium-238 is four and half billion years. That means that it will be around for a very long time, but since its decay rate is so slow, it is not very radioactive. The half-life of Uranium-235 is 710 million years, again it will be around for a very long time, but again, since its decay rate is so slow, it is not very radioactive. The half-life Uranium-234 is 247,000 years, a little bit faster but it still has a pretty slow decay rate.
This should be compared to Cesium-137, which has a half-life of roughly 30 years. In other words, it decays 150 million times faster than Uranium-238 and 23.7 million times faster than Uranium-235. Since Cesium-137 decays so much faster than the Uranium isotopes it means that each atom of Cesium-137 will send out radioactive particles much more often than a Uranium atom will, making it much more radioactive.
If you want to read about when I was walking around a whole day with a Cesium-137 sample in the back pocket of my jeans, click here. Radon-222, an extremely radioactive isotope of radon, which seeps into our basements from the inside of earth. It has a half-life of 3.82 days giving it a decay rate that is 430 billion times faster than Uranium-238 and 68 billion times faster than Uranium-235.
What makes it possible to make a nuclear bomb from Uranium-235 is not because it is very radioactive. It is not. It is because it has properties that make it perfect for bomb making. Each nucleus emits more than one neutron, in fact more than two on average, and the neutrons colliding with other Uranium-235 nucleuses can be made to travel at the correct speed to cause fission. In other words, it is fissile. It is a goldilocks situation. It is just right. Below is an illustration showing a chain reaction. Observe, the picture indicates that Uranium has 95 protons. This is wrong. Uranium has 92 protons. When I have the time, I will fix this picture.
This is an illustration of a chain reaction with fission of a Uranium-235 isotope. Notice the atomic number (number of protons) is incorrectly stated as 95 in the picture. It is 92. When I have time, I will fix that. Shutterstock Asset id: 73714504 by Mpanchenko.
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.
According to the Arms Control Association there’s been 2,056 nuclear bomb tests. According to the UN there’s been more than 2,000 nuclear bomb tests, and according to Wikipedia there’s been 2,121 nuclear bomb tests, totaling 635 Megaton. Using the typical yield estimate for the Hiroshima bomb of 15 Kiloton that corresponds to more than 42,000 Hiroshima bombs. I think most of us know about the Hiroshima and Nagasaki bombs and we know about nuclear testing. However, I think the number of tests and the large total yield will come as a surprise to many, at least it was a surprise to me. That is why I consider this a super fact.

Nuclear Landscaping
It may also come as a surprise that many of these tests were not for military purposes. Another usage for nuclear bombs is nuclear landscaping. Towards the end of the 1950’s the existing Panama Canal was thought to be insufficiently large and some people, including Edward Teller, the father of the Hydrogen bomb (Thermonuclear bomb), suggested that a new wider and deeper canal could be built simply by using nuclear bombs to blow multiple huge holes across Panama. The US was also interested in creating a new harbor in Alaska using nuclear bombs.
Thus, Project Plowshare was created to achieve this. As part of the Project Plowshare 35 nuclear warheads were detonated. The Soviet Union also had a similar program named “Nuclear Explosions for the National Economy” that included 124 nuclear bomb tests. Due to concerns over radioactive fallout the nuclear landscaping projects were eventually put to rest. The last Plowshare detonation was on May 17, 1973. The book Atomic Awakening by James Mahaffey recounts the history of nuclear testing and nuclear landscaping in greater detail.

Project Orion
Another non-military use of nuclear bomb testing was Project Orion. Project Orion was a study conducted from 1956 to 1964 by the US Air Force, NASA, and DARPA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft. A thick steel pusher plate would catch the blast and accelerate the ship forward.
The “Pascal B” shot in Operation Plumb Bob in 1957 was the first nuclear weapons test of the pusher concept. The Limited Test Ban Treaty of 1963 made it difficult to continue with the project. According to the book Atomic Awakening, if the design had been successfully completed, we could have created an interstellar spaceship that could have taken a crew and a large load to other planets and stars.
I can add that According to Atomic Awakening, in addition to Nuclear Landscaping and Project Orion, Nuclear Blasts were a tourist attraction.
Number of Nuclear Tests by Country
Below is a list of countries and the number of nuclear tests that they’ve performed according to the Arms Control Association and Wikipedia.
The United States – 1,030 – According to Wikipedia – 1,032
The USSR/Russia – 715 – According to Wikipedia – 727
France – 210 – According to Wikipedia – 215
United Kingdom – 45 – According to Wikipedia – 88
China – 45 – According to Wikipedia – 47
North Korea – 6 – According to Wikipedia – 6
India – 3 – According to Wikipedia – 3
Pakistan – 2- According to Wikipedia – 2
However, it should be noted that partially due to nuclear arms control legislation such as; the Limited Test Ban Treaty (LTBT): Signed in 1963, the Threshold Test Ban Treaty (TTBT): Signed in 1974, and the Comprehensive Nuclear-Test-Ban Treaty (CTBT) opened for signing in 1996, the number of nuclear tests have been significantly reduced. This is illustrated by the graph below from Our World in Data. The last nuclear test was done by North Korea in 2017.
The biggest nuclear bomb ever exploded was RDS-220, or AN602, or Tsar Bomba. It was detonated by the Soviet Union on October 30th, 1961, on the arctic island of Novaya Zemlya, and yielded more than 50 Megaton. In other words, it was 3,300 times more powerful than the Hiroshima bomb. According to Atomic Awakening, windows in Finland 1,900 kilometers (1,180 miles) away shattered. There are no cities large enough to match the size of the explosion. This is the kind of bomb that could obliterate states or small countries.
Tsar Bomba was a so-called thermonuclear device, or a hydrogen bomb as they are typically called. Hydrogen bombs are much more powerful than fission bombs, such as Uranium bombs or Plutonium bombs. To read my related post called “Ukraine Gave up Thousands of Nuclear Warheads” click here.
