I would like to think we are entering a saner time with the second Trump presidency, a better energy policy, perhaps a chance at reeling in the insane Federal deficit, some respect for the constitution and the rights elucidated in said document, and perhaps we can end some of the homelessness and poverty and the general death cult that has enveloped not only our nation but the world.
The biggest challenge I see in our future though isn’t global warming or poverty, or freedom, it is polarization. People are so polarized now that we can’t even communicate the areas we agree upon and perhaps act favorably upon those.
My concern for the future of humanity is less that we’re going to fry ourselves in an overheated planet, more than we’re going to run out of commercially viable fossil fuels and not have a replacement. Then we won’t be able to grow distribute food let alone do all of the other activities necessary to our survival.
Let me discuss a few myths, and explain how I’ve come to the conclusions that I have. First, you often here quoted that 97% of Scientists agree that human caused global warming by our emission of greenhouse gases is an existential threat is a falsehood. It is a lie spread by those with heavy investments in these fuels to create artificial scarcity thus driving up prices and enriching themselves. It is probably true that 97% of scientists would agree that global warming is in part exacerbated by human activity, and that we play at least a minor role, but probably less than 3% agree that it is an existential threat or that it is anywhere near that which mainstream media portrays. I am inclined to agree with this view though I also would say it is a source of unnecessary disruption that could be largely avoided.
Let me explain some of the reasons for my beliefs. First, there is a lack of good data. Oh you can say yes we have direct temperature readings going back more than 100 years, and these records show significant warming. What most people don’t know is that almost all land weather stations are in heat islands, near busy airports or in busy metropolitan settings that are on average 3-10 degrees Fahrenheit warmer than average temperatures. And satellite temperature readings tend to suggest a decrease, and it is argued this is because they are measuring the upper atmosphere above where the heat is trapped. Both of these things are true, and the result is we do not have good reliable temperature data. Thus we have nothing to test models against that is reliable and thus we can not determine how reliable models are.
And then there are psychological factors. Every year somewhere we beat all time temperature highs. But by the same token every winter somewhere we break all time temperature lows. Psychologically this feels threatening, but the truth is that weather is a fractal pattern sitting on top of cyclic variations, and thus the longer the sample time the greater the excursions. There is also much media hype suggesting an increase in the frequency and strength of tropical storms and of forest fires, neither is true. If you look at data that only goes back to 1980 you can see a rise, but if you look back to 1900, you’ll see 1925-1935 is the absolute worst period by a wide margin for both.
So let’s talk about physics for a minute. First, methane though it might be a much stronger greenhouse gas in terms of the spectrum it can trap, it only lasts on average 12 years in the atmosphere, this means it is NOT a long term threat. It is claimed carbon-dioxide lasts hundreds to thousands of years, again not born out in the data, there is considerable variation between summer and winter in the Northern hemisphere because three fourths of the worlds lands masses are in the Northern hemisphere and thus there is significant differences in photosynthesis over the course of a year, and since these variations make a significant difference in only a fraction of a year, one can surmise that the lifetime of carbon dioxide is much shorter than advertised, especially since increased CO2 has resulted in radically increased photosynthesis removal of CO2, but photosynthesis is only a minor removal of CO2, the majority removal mechanism is marine life. Marine life uses CO2 to build it’s calcium-carbonate shells, these creatures then die and their shells fall to the seafloor. The seafloor eventually subducts under a another crustal plate and with the exception of a small amount of CO2 returned to the atmosphere when a small portion of that crust melts and returns to the surface via volcanism. This process is in fact what is mainly responsible for the decline of carbon dioxide levels from 3000-5000 parts per million near the beginning of the time of dinosaurs to the 280 parts per million around the beginning of the 20th century. And this process ultimately will be what terminates life on Earth.
Another reason I believe that the cause for CO2 caused warming is exaggerated is the physics involved. Gases do not absorb radiation over a broad spectrum, they absorb along narrow spectral lines. When those lines fall near the maximum wavelength of black body radiation for the Earth’s temperature, they have maximal effect. When the temperature rises or falls such that the peak of the black body radiation no longer corresponds with the absorptive spectral lines, then they have less effect. And carbon dioxide is already at a level where these lines are saturated by approximately 12 feet off the ground. Adding more carbon dioxide will slightly broaden these lines but it will not increase their depths. It is for this reason that adding additional CO2 is NOT a linear but rather a diminishing effect.
There is much talk of a “tipping point”, a point beyond which there will be a runaway green house effect, and Venus is actually often referred to as an example, but there are gross misrepresentations here. First, Venus receives 50% again as much solar radiation per square meter of atmosphere than Earth does. Second, Venus has an atmosphere approximately 100x as thick as the Earth’s, no matter what it’s makeup that’s a much thicker insulating blanket. Lastly, Venus has no plate tectonics, no photosynthesis, and no marine life to remove CO2, and no water cycle to remove it via mineral weathering. So this is an Apples to Watermelon comparison, two entirely different systems. Venus didn’t runaway, it NEVER had any method of removal. All fo the CO2 EVER put into Venuses atmosphere is still there. Earth on the other had started out with mostly nitrogen, then CO2, and then a small amount of argon in it’s atmosphere and over time has become 78% nitrogen, 1% argon, 21% oxygen, and just a smiggin of CO2.
All that said, the Earth is very good at homeostasis and there are mechanisms that somewhat counter the effects of the increased CO2, for example, there is 15% MORE area that has green plants since 1900, this is because plants have little pores called stomata to take in CO2 which is their food, and when CO2 is sparse they have more of them and they are opened longer. This results in greater water loss resulting in no survival in arid regions, but as CO2 increases, they produce fewer stomata and they do not keep them as open as long. This results in better water retention and better survival in arid regions. As a result we see greening of what used to be deserts. We also see more CO2 dissolved in oceans which up to a point results in marine life removing it faster, and we also see faster weathering of rock, also removing it faster, all of these mechanisms means the CO2 we put into the air will be removed at a higher rate than it has in the past.
Now there are some aspects of the Earth’s systems that are negatively affected, and these are greater concern I think than warming per se’. For example, you hear of Arctic ice, especially Greenlandic and Icelandic glaciers being removed at a faster rate, well it is true they are calving at a higher rate but also there is more snow being precipitated resulting in a net glacier growth. This might seem to be a good thing but where Greenland is concerned it is not, because the difference in salinity is what drive the so called Atlantic circulation belt, and all the fresh water being added is slowing that belt, this means, less warm water is being brought up from tropical regions into the subtropical, temperate, and arctic zones. So what we get is not global warming but global heat redistribution. Particularly we get a cooling not warming of Western Europe. But because of the increased precipitation of snow we do not get the huge global warming people predict in the near future.
This is undesirable, this is a point I think we can all agree upon, but then there is the question of solutions. The most extreme solutions is what the World Economic Forum is pushing for, lock us all into 15-minute prisons, forbid travel, forbid the use of the majority of the Earth’s land masses, have us all eat even less non-nutritious artificial food so we’ll die sooner, and if that doesn’t kill us, generate some deadly diseases and introduce them into the population, and if that doesn’t spread naturally enough to kill enough of us, inject us with it. Not a solution I would favor. The next favored solution is to produce all of our energy with wind and solar and electrify all of our transportation, this is better but not economically viable, and not viable from a standpoint of the mineral resources required both for production and storage of energy this way, primarily lithium and rare Earth’s, neither can be obtained in sufficient quantity economically.
So what is left? Well, start by cutting out waste. If we didn’t waste so much energy on military that would be a big plus right there. Next thing, we need new base load energy sources. We are on the cusp of three potentially viable new sources, one source and one I would want to see developed for reasons beyond energy, is molten salt breeder reactors. These can burn thorium indirectly by breeding it into Uranium 233, but they can also burn all the actinide waste from existing spent fuel, and this is the long term nuclear waste. You burn it up and it leaves only short term fission products that only need to be kept isolated for about 300 years rather than 100,000 to a million. Three hundred years is realistically doable, 100,000 isn’t. Thorium is 3x as more abundant in the Earth’s crust than Uranium and 100% of it is usable not just the .6% of Uranium that is U-235, also with this technology the other 99.4% of uranium that is U-238 would become usable. Yet another advantage of molten salt reactors is that molten salts also being used as the heat exchange mechanism, these can be stored in tanks when power isn’t required and then used to provide peak power beyond the reactors capability when load demands it. This makes them a perfect adjunct to intermittent sources like Wind and Solar.
Another technology that has been in the works for a long time is nuclear fusion, and for many years we were unable to reach scientific break even let alone commercial break-even. But Wendlestein-7x stellarator recently achieved a gain of 320, that is it produced 320 times as much energy from fusion as that which was required to initiate the reaction. Now there is still engineering work to be done, but the science is there.
And yet another technology involves a new form of drilling that involves a megawatt maser microwave source. This new technology makes drilling holes deep enough to reach geothermal resources virtually anywhere viable. But even without this technology, here in the United States, we have a huge national resource of geothermal energy near enough the surface to easily tap known as Yellowstone but federal law prohibits tapping it. This is beyond ludicrous.
At any rate; if we cripple our economy in order to “save the planet”, we cripple our ability to put in place these new technologies and ultimately make the problem larger in the long run, or we guarantee our extinction and fix it that way. Neither seems desirable to me. But one thing I am sure of, we can’t get to a better place by constantly fighting each other. We need to be willing to discuss, determine what things we can agree upon and at least pursue those.
