Molten Salt nuclear Reactors operate under Atmospheric pressure conditions, no risk for explosions. Materials subjected to high radiation tend to get brittle or soften up. Molten Salt Thorium nuclear reactors operate under atmospheric conditions so the choice of materials that can withstand both high temperatures and high radiation is much greater, leading to a superior and less expensive design. There is no high pressure gas buildup and the separation stage can be greatly simplified, leading to a much safer design. (From Wikipedia:)
The LFTR needs a mechanism to remove the fission products from the fuel. Fission products left in the reactor absorb neutrons and thus reduce neutron economy. This is especially important in the thorium fuel cycle with few spare neutrons and a thermal neutron spectrum, where absorption is strong. The minimum requirement is to recover the valuable fissile material from used fuel.
Removal of fission products is similar to reprocessing of solid fuel elements; by chemical or physical means, the valuable fissile fuel is separated from the waste fission products. Ideally the fertile fuel (thorium or U-238) and other fuel components (e.g. carrier salt or fuel cladding in solid fuels) can also be reused for new fuel. However, for economic reasons they may also end up in the waste.
On site processing is planned to work continuously, cleaning a small fraction of the salt as often as practical and sending it back to the reactor. There is no need to make the fuel salt very clean; the purpose is to keep the concentration of fission products and other impurities (e.g. oxygen) low enough. The concentrations of some of the rare earth elements must be especially kept low, as they have a large absorption cross section. Some other elements with a small cross section like Cs or Zr may accumulate over years of operation before they are removed.
As the fuel of a LFTR is a molten salt mixture, it is attractive to use pyroprocessing, high temperature methods working directly with the hot molten salt. Pyroprocessing does not use radiation sensitive solvents and is not easily disturbed by decay heat. It can be used on highly radioactive fuel directly from the reactor. Having the chemical separation on site, close to the reactor avoids transport delays and risks and keeps the total inventory of the fuel cycle low. Ideally everything except new fuel (thorium) and waste (fission products) stays inside the plant.
One potential advantage of a liquid fuel is that it not only facilitates separating fission-products from the fuel, but also isolating individual fission products from one another, which is lucrative for isotopes that are scarce and in high-demand for various industrial (radiation sources for testing welds via radiography), agricultural (sterilizing produce via irradiation), and medical uses (Molybdenum-99 which decays into Technetium-99m, a valuable radiolabel dye for marking cancerous cells in medical scans).
Mo-99 is used in hospitals to produce the technetium-99m employed in around 80% of nuclear imaging procedures. Produced in research reactors, Mo-99 has a half-life of only 66 hours and cannot be stockpiled, and security of supply is a key concern. Most of the world’s supply currently comes from just four reactors in Belgium, the Netherlands, Russia and South Africa, and recent years have illustrated how unexpected shutdowns at any of those reactors can quickly lead to shortages. Furthermore, most Mo-99 is currently produced from HEU targets, which are seen as a potential nuclear proliferation risk.
With the Mo-99 having a half-life of 66 hours and being continuously separated out from the fertile core in a LFTR, this seems to be the ideal vehicle to cheaply produce ample supplies of this valuable medical resource.
While LFTR reactors can be built today safely and profitably, much work remains to be done to achieve the full eight to ten thousand times reduction in TRU waste and maximize the breeding rate of U-233 for optimal speed of expanding the Thorium program.
Molten Salt Thorium Reactors are earthquake safe. Thorium reactors have a very simple and compact design where gravity is the only thing needed to stop the nuclear reaction. Conventional nuclear reactors depend on external power to shut down after a SCRAM, where poison rods fall down to halt the reaction. The next figure shows the concept of a Thorium reactor.
The idea is to empty the fissile U-233 core through gravity alone. All that is needed is a melt-plug that is constantly cooled by cold air. In an earthquake or complete electric failure the cold air flow automatically shuts off, and since the fuel is already molten, it will melt the plug, and the molten fluid will run down into channels like pig-iron into heat exchangers that absorb the residual heat.
As we can see the reactor hardened structure is compact, and can be completely earthquake and tsunami proof. What can be sheared off are the steam pipes and external power, but even then the reactor shutdown will be complete safe without any additional power.
One of the advantages of the LFTR reactor is that the fissile compartment is always kept just above critical point for needed power delivery. This means, once it starts draining, the fission process ends immediately. The only nuclear reaction remaining is that the Protactinium generated in the fertile blanket and separator gets converted to U-233 over time, but the amounts are so small that it is always in the safe range.
Thorium based Nuclear Power does not produce much Plutonium-239, which is the preferred material used in nuclear bombs. The higher Plutonium isotopes and other TRansUraniums are about as nasty as they get, need expensive protection against terror attacks, and need to be stored for a very long time.
One anecdote from my youth. The time had come to apply to University, and to my delight I was accepted to Chalmers’ University in Sweden as a Technical Physics major. I felt, maybe I can do my part by becoming a Nuclear Engineer and help solve the energy needs of the future. The Swedes at that time championed the heavy water – natural Uranium program together with the Canadians and to some extent with the Indians. Sweden was and to some extent still is a non-aligned country, so it was not privy to any nuclear secrets, it had to go it alone. They settled on the heavy water moderated natural Uranium process because Sweden had an ambition to produce its own nuclear bomb. Officially this was never talked about, and I was not aware of it at that time. They could have gone with Thorium instead, but a Thorium based nuclear reactor produces very little Plutonium, and what it produces is nearly all Pplutonium-238, not fissile and as such not suitable for bomb making.
I was excited to learn about all the possibilities and signed up for a couple of nuclear classes. One lab was to design a safety circuit, then run the heavy water research reactor critical and hopefully watch the reactor shut down from the safety circuit before the system safety circuit shutdown. About that time the word came that U.S. will sell partially enriched uranium at bargain basement prices if Sweden agreed to abandon the heavy water project and sign the nuclear non-proliferation treaty, a treaty being formulated by U.N.
Sweden was in awe about U.N, all the problems of the world were to be solved through it, and it had such a capable General Secretary in Dag Hammarskjöld, a Swede. I looked at the light water, partially enriched Uranium nuclear power plants being developed and decided to have no part with it, not due to safety concerns but it was the design that produced the most nuclear waste of any of the available designs. At that time there was still optimism that fusion would be ready by about the year 2010 or so. The cost of maintaining spent fuel in perpetuity was never considered, so light water reactors became the low cost solution.
India on the other hand refused to join the nuclear non-proliferation treaty, kept their heavy water program going and had by 1974 produced enough plutonium for one nuclear bomb, which they promptly detonated. They still use heavy water moderated reactors, but since India is low on Uranium but rich in Thorium they have now converted one heavy water reactor to Thorium with a Plutonium glow plug. It went on-line in 2011.
They are also developing molten salt Thorium reactors, but full production is still a few years off.
There we have it. We could have gone with Thorium from the beginning, but the cold war was on, and the civilian peaceful use of nuclear energy was still all paid for by nuclear weapons research and development. Once all the bombs we could ever wish for were developed the greatest asset of nuclear power became its greatest liability.
Radioactive waste from an LFTR (Liquid Fluoride Thorium Reactor) decays down to background radiation in 300 years instead of a million years for U-235 based reactors. Initially LFTRs produce as much radioactivity as an U-235 based nuclear reactor, since fission converts mass to heat, but the decay products have a much shorter half-life. See the figure below.
Where is the storage for spent nuclear fuel and other nuclear waste now? Look at the map, it is scary.
And these are just the U.S. installations!
Many years ago I studied Engineering at Chalmers’ University in Sweden and I thought I would become a nuclear engineer. Sweden had at that time a peaceful heavy water based nuclear power program together with Canada and India. The advantage with heavy water as moderator is that it can use natural, un-enriched Uranium. One of the end products is of course Plutonium 239, the preferred material to make nuclear bombs, but it could also use Thorium, and the end product is then mostly Plutonium 238, used in space exploration, and we were dreaming big. One of the advantages of Thorium as fuel is that it produces about 0,01% of trans-Uranium waste compared to Uranium as fuel. About that time the U.S. proposed we should abandon the heavy water program and switch to light water enriched Uranium based nuclear power. They would sell the enriched Uranium, and reprocess the spent fuel at cost. They also had the ideal final resting place for the radioactive waste products in Nevada. This was an offer the Swedish government could not refuse, at the height of the cold war. This was in the 1960’s! India on the other hand did refuse, and they eventually got the nuclear bomb. Since that meant Sweden was never going to use Thorium as nuclear fuel, and I could not figure out how to get rid of all the radioactive waste products, I switched my attention back to control engineering.
.What did President Trump mean with innovative approaches?
Is this where Thorium comes in!? Thorium solves many problems with nuclear energy. Meanwhile the Biden administration and Congress keep hoarding nuclear waste in local storages.
Thorium nuclear power is the only realistic solution to power space colonies. To form space colonies, power has to be provided to sustain the colony. This means that Liquid Fluoride Thorium Reactors (LFTR) have to be fully developed and operational here on earth before serious space colony development can even begin. It need to get started in earnest NOW!
Kirk Sorensen has provided an intriguing teaser on the case for Thorium nuclear energy.
A Thorium based nuclear power generator produces Pu-238 as one of the final TRansUranium products, which is in short supply and much in demand for space exploration nuclear power.
NASA relies on pu-238 to power long-lasting spacecraft batteries that transform heat into electricity. With foreign and domestic supplies dwindling, NASA officials are worried the shortage will prevent the agency from sending spacecraft to the outer planets and other destinations where sunlight is scarce. Thorium reactors produce PU-238 as a “free” byproduct. In 2009 Congress denied a request to produce more Pu-238 by traditional means, instead relying on Russia to sell us the plutonium. (Remember the Russian reset?) Russia made their last delivery in 2010. PU-238 production has since been restarted by converting Ne-237 to Pu-238 at a cost of over 8 million dollars per kilogram. The Ceres-Dawn spacecraft used over 22 Kg of Pu-238 as electricity generator.
To get the best efficiency of generating Pu-238 out of a molten salt Liquid Fluoride Thorium Reactor, the excess U-233 and TRansUranium products have to be extracted continuously while the reactor is running, and this technology is not yet implemented, but is necessary to implement before we can also have Thorium power on the moon, and Thorium Power is the only viable solution if we are ever going to have a moon colony, so we should rapidly develop the technology privately and with the cooperation of the Space Force and NASA.
Uranium or thorium, or any combination thereof, in any physical or chemical form, or ores that contain, by weight, one-twentieth of one percent (0.05 percent) or more of (1) uranium, (2) thorium, or (3) any combination thereof. Source material does not include special nuclear material. For additional detail, see Source Material.
Thorium 232 has a half life of 14 billion years, about the same as the generally accepted age of the universe until the dell telescope discovered much more than was known
Uranium 238 has a half life of 4.5 billion years and Uranium 235 has a half life of 700 million years.
In addition Uranium has as its first transition Thorium generation on its path down to the final stable state, Lead. This means that Uranium is at least four times as radioactive as Thorium.
It is interesting to observe that in the decay path of both Uranium and Thorium they pass through Radon and emit two alpha particles on the way.
The definition for Source material should therefore be changed to:
Uranium or thorium, or any combination thereof, in any physical or chemical form, or ores that contain, by weight, one-twentieth of one percent (0.05 percent) or more of (1) uranium, 0.2 percent of (2) thorium, or (3) any proportional combination thereof.
Why is this important? The U.S. used to be world leader in rare earth metals production. Then when the regulation on Source Material was instituted, mining rare earth metals with a small amount of Thorium became unprofitable and China took over, and developed a near monopoly on the market, in effect making rare earth metals single sourced. Rare earth metals, as well as Thorium is of great strategic value.
Here is an example:
This is the Mount Weld Rare Earth Mine in Western Australia. It is owned by Lynas Corporation. The mined ore, after concentration is shipped to Malaysia for final refining. The concentrated ore contains 30% rare earth metals ready for separation, but the ore also contains 0.16% Thorium. For the moment, only the most sought after rare earth metals are refined, the rest are left on the slag heap, which includes Thorium. This makes it nuclear waste according to a multitude of protestors, after all it is source material. To complicate matters further, China is looking to grab the mine, so they stir up as much trouble as possible
This is insanity. In 2011 the Oak Ridge Laboratories had a stockpile of 1400 kg U 233. They have been busy downblending it into depleted uranium to render it useless, and there is now only about 450 kg left. Unless this insanity is stopped asap Thorium nuclear power will be set back immensely, since U233 is used as the startplug for the cleanest Thorium nuclear power production
The bill is introduced. It should be immediately passed in the Senate, and be passed in the house without amendments. Any delay is critical. It is that important. We gave the technology to the Chinese so they can build up their naval fleet with molten salt Thorium nuclear power. Meanwhile we still have some u-233 left, worth billions as a National Security asset. At the very least, we must stop downblending immediately, even before the bill is passed.

To provide for the preservation and storage of uranium-233 to foster development of thorium molten-salt reactors, and for other purposes.
IN THE SENATE OF THE UNITED STATES
May 18 (legislative day, May 17), 2022
Mr. Tuberville (for himself and Mr. Marshall) introduced the following bill; which was read twice and referred to the Committee on Energy and Natural Resources
A BILL
To provide for the preservation and storage of uranium-233 to foster development of thorium molten-salt reactors, and for other purposes.
Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,
SECTION 1. Short title.
This Act may be cited as the “Thorium Energy Security Act of 2022”.
SEC. 2. Findings.
Congress makes the following findings:
(1) Thorium molten-salt reactor technology was originally developed in the United States, primarily at the Oak Ridge National Laboratory in the State of Tennessee under the Molten-Salt Reactor Program.
(2) Before the cancellation of that program in 1976, the technology developed at the Oak Ridge National Laboratory was moving steadily toward efficient utilization of the natural thorium energy resource, which exists in substantial amounts in many parts of the United States, and requires no isotopic enrichment.
(3) The People’s Republic of China is known to be pursuing the development of molten-salt reactor technology based on a thorium fuel cycle.
(4) Thorium itself is not fissile, but fertile, and requires fissile material to begin a nuclear chain reaction. This largely accounts for its exclusion for nuclear weapons developments.
(5) Uranium-233, derived from neutron absorption by natural thorium, is the ideal candidate for the fissile material to start a thorium reactor, and is the only fissile material candidate that can minimize the production of long-lived transuranic elements like plutonium, which have proven a great challenge to the management of existing spent nuclear fuel.
(6) Geologic disposal of spent nuclear fuel from conventional nuclear reactors continues to pose severe political and technical challenges, and costs United States taxpayers more than $500,000,000 annually in court-mandated payments to electrical utilities operating nuclear reactors.
(7) The United States possesses the largest known inventory of separated uranium-233 in the world, aggregated at the Oak Ridge National Laboratory.
(8) Oak Ridge National Laboratory building 3019 was designated in 1962 as the national repository for uranium-233 storage, and its inventory eventually grew to about 450 kilograms of separated uranium-233, along with approximately 1,000 kilograms of mixed fissile uranium from the Consolidated Edison Uranium Solidification Program (commonly referred to as “CEUSP”), divided into approximately 1,100 containers.
(9) The Defense Nuclear Facilities Safety Board issued Recommendation 97–1 (relating to safe storage of uranium-233) in 1997 because of the possibility of corrosion or other degradation around the storage of uranium-233 in a building that was built in 1943.
(10) In response, the Department of Energy published Decision Memorandum No. 2 in 2001 concluding that no Department of Energy programs needed uranium-233 and directed that a contract be placed for disposition of the uranium-233 inventory and decommissioning of its storage facility.
(11) The Department of Energy awarded a contract for the irreversible downblending of uranium-233 with uranium-238 and its geologic disposal in Nevada, which downblending would create a waste form that would pose radiological hazards for hundreds of thousands of years, rather than to consider uranium-233 as a useful national asset.
(12) All 1,000 kilograms of CEUSP uranium-233-based material have been dispositioned (but not downblended) but those containers had little useful uranium-233 in them. The majority of separated and valuable uranium-233 remains uncontaminated by uranium-238 and suitable for thorium fuel cycle research and development. That remaining inventory constitutes the largest supply of uranium-233 known to exist in the world today.
(13) The United States has significant domestic reserves of thorium in accessible high-grade deposits, which can provide thousands of years of clean energy if used efficiently in a liquid-fluoride reactor initially started with uranium-233.
(14) Recently (as of the date of the enactment of this Act), the Department of Energy has chosen to fund a series of advanced reactors that are all dependent on initial inventories and regular resupplies of high-assay, low-enriched uranium.
(15) There is no domestic source of high-assay, low-enriched uranium fuel, and there are no available estimates as to how long the development of a domestic supply of that fuel would take or how expensive such development would be.
(16) The only viable source of high-assay, low-enriched uranium fuel is through continuous import from sources in the Russian Federation.
(17) The political situation with the Russian Federation as of the date of the enactment of this Act is sufficiently uncertain that it would be unwise for United States-funded advanced reactor development to rely on high-assay, low-enriched uranium since the Russian Federation would be the primary source and can be expected to undercut any future United States production, resulting in a dependency on high-assay, low-enriched uranium from the Russian Federation.
(18) The United States has abandoned the development of a geologic repository at Yucca Mountain and is seeking a consenting community to allow interim storage of spent nuclear fuel, but valid concerns persist that an interim storage facility will become a permanent storage facility.
(19) Without a closed fuel cycle, high-assay, low-enriched uranium-fueled reactors inevitably will produce long-lived wastes that presently have no disposition pathway.
(20) The United States possesses enough uranium-233 to support further research and development as well as fuel the startup of several thorium reactors. Thorium reactors do not require additional fuel or high-assay, low-enriched uranium from the Russian Federation.
(21) Continuing the irreversible destruction of uranium-233 precludes privately funded development of the thorium fuel cycle, which would have long term national and economic security implications.
SEC. 3. Sense of Congress.
It is the sense of Congress that—
(1) it is in the best economic and national security interests of the United States to resume development of thorium molten-salt reactors that can minimize long-lived waste production, in consideration of—
(A) the pursuit by the People’s Republic of China of thorium molten-salt reactors and associated cooperative research agreements with United States national laboratories; and
(B) the present impasse around the geological disposal of nuclear waste;
(2) that the development of thorium molten-salt reactors is consistent with section 1261 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019 (Public Law 115–232; 132 Stat. 2060), which declared long-term strategic competition with the People’s Republic of China as “a principal priority for the United States”; and
(3) to resume such development, it is necessary to relocate as much of the uranium-233 remaining at Oak Ridge National Laboratory as possible to new secure storage.

If you live in the higher latitudes, rain is a nuisance, and as they say in England: Everybody complains about the weather, but nobody does anything about it. In areas of drought, rain is a blessing. The quip ‘poem’ refers to the Bible (of course) and can be found in Matthew 5:43-45. Jesus says in the sermon on the mount:
43 “You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ 44 But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you, 45 that you may be sons of your Father who is in heaven. For He makes His sun rise on the evil and on the good and sends rain on the just and on the unjust. (Modern English Version).
It all goes back to the beginning: The Bible says in Genesis 1:
In the beginning God created the heavens and the earth. 2 The earth was formless and void, darkness was over the surface of the deep, and the Spirit of God was moving over the surface of the water.
3 God said, “Let there be light,” and there was light. 4 God saw that the light was good, …..
So the evening and the morning were the first day.
6 Then God said, “Let there be an expanse in the midst of the waters, and let it separate the waters from the waters.” 7 So God made the expanse and separated the waters which were under the expanse from the waters which were above the expanse. And it was so. 8 God called the expanse Heaven. So the evening and the morning were the second day.
Day 3,4,5 and 6 God created Sun, Moon and stars, flora and fauna all after its kind, and at the end of each day God saw that it was good. But God didn’t say it was good after day two!
At the end of day six 26 Then God said, “Let us make man in our image, after our likeness, and let them have dominion over the fish of the sea, and over the birds of the air, and over the livestock, and over all the earth, and over every creeping thing that creeps on the earth.”
27 So God created man in His own image; in the image of God He created him; male and female He created them.
After God had created man in His own image, one kind, two equivalent sexes, male and female, the ecosystem that was started in day 2 was complete, including man and woman; God could finally say: It was very good. God gave us the stewardship of earth, and it is our responsibility not to destroy God’s creation.
There is now great anxiety that we will exceed the all important 1.5 degree Celsius temperature increase since pre-industrial times soon, since we are about to have another el niño. A direct quote in Jan 2019 from scaremonger congresswoman Alexandra Ocasio-Cortez states: ‘The world is going to end in 12 years if we don’t address climate change,‘ Her ‘solution’ is to follow the climate alarmists and do away with all fossil fuel in the next 8 years or sooner. As if that would solve anything.
There is a better solution. CO2 is our strongest greenhouse gas, next after water vapor, which is between 5 and 10 times stronger. In fact water vapor is a condensing gas and exists in the atmosphere as unsaturated, oversaturated, as water drops and as ice crystals. The critical thing about precipitation as rain or snow is that it is increasing in areas that already get enough, and is decreasing in areas of insufficient rain or snow. Since 1901, global annual precipitation has increased at an average rate of 0.04 inches per decade, while precipitation in the contiguous 48 states has increased at a rate of 0.20 inches per decade. The eastern parts of the United States have experienced greater increases in precipitation, while the American southwest has experienced a decrease. For example, the Colorado river basin has experienced an annual precipitation decline of 0.6 inches per decade, see fig.
Looking at all of the contiguous 48 states, the precipitation figure looks like this:
In the East it is all about water responsibilities, you must build a catch basin to catch the water that falls on roads and roofs and other paved surfaces, and release it slowly to lessen floods. In the West it is the other way around, it is all about water rights. If you don’t own the water rights on your property you are not even allowed to water the plants outside with the water that falls on the roof of your own house, even though thatt would benefit the aquifer. In fact, one of the most effective way to destroy the environment is to deplete the aquifers. The situation for the aquifers in the world is already dire. Nearly all big cities in the 10-40 latitudes zone that are not fed by major rivers are already depleting their aquifers at an alarming rate. Mexico City e.g. have exhausted their aquifers and are looking for more water supplies. In addition the lakes are disappearing. Salt Lake is a third of what it was in 1970,The Aral Sea is but a memory, rivers are being dammed so much that even the Euphrates river was running dry last fall, the list goes on. This must be solved.
This is a proposal. As in the east, let the water rights belong to the property and cannot be sold separately. This way the water can be stored where it will do most good, at the source. With this comes water responsibility. The landowner is responsible for maintaining the aquifer, and keep it replenished at all times. In times of drought, the aquifers can be temporarily drawn down if there is no water available to purchase at market value. This requires a water exchange market, complete with futures. (This is much more important than a Carbon exchange market). When the drought is over the aquifers must be refilled over time. The West is mostly federal land, except for Indian reservations, see map:
The Indian reservations will be given back the water rights they had before it was taken from them, which was the water that rained on their land. In addition they will be given back the right to use the water from the rivers up to the point of reason, that is what was used before settlers came and took the water rights. They will get the river water free, that will be their reparations, everyone else will have to pay market price for river water. (In the east, the rivers will have excess water, so the price will be zero. and the price for cleaning the water will be paid by the consumer). In the American Southwest, water is the most valuable resource, so water should be priced in an open market.
But how does all of this affect climate change?
The American Southwest is becoming desertified. That means it is slowly made a desert. The aquifers are being depleted and rain is diminishing. This leads to less clouds and even less rain. The worst example is the disappearance of the Aral Sea. Central government (of CSSR) thought it was a good idea to grow cotton and irrigate the land. After a few years of great harvests the rivers dried up, the lake almost disappeared, the clouds disappeared and the rains stopped. This was done in the 70’s and a million people had to be resettled to where there still was water.
The solution is to change the land use to produce more clouds and more rain and snow. To collect the water in lakes, dams and rivers leads to more evaporation, but not more clouds and rain. Only well restored aquifers will solve the problem, together with replanting indigenous trees and other vegetation. For example Pine trees emit ideal aerosols for cloud generation when water vapor becomes oversaturated thanks to evapotranspiration from the same trees. The aquifers must be sufficiently refilled to sustain trees. The trees makes the soil cooler, so unwanted evaporation will be less. The same forests must be well maintained to avoid large wildfires.
It is expensive, but much cheaper than trying to solve climate change by mining up the whole world trying to find enough Lithium, Cobalt and rare earth metals for all the electric cars, trucks and batteries to store the energy needed when the sun doesn’t shine and the wind doesn’t blow. A hint: Use Thorium to replace coal for electricity production, It is already mined when mining rare earth metals. There are many reasons to produce Thorium Nuclear Power. Here are 30 of them
By far, the strongest greenhouse gas is water vapor, not because it is very strong of itself, but it absorbs nearly all outgoing energy in the infrared spectrum except in the so called atmospheric window, where it only partially absorbs. Yet water vapor is missing from the IPCC calculations. Instead is put in a forcing multiplier to account for the water vapor
IPCC has consistently treated the effect of greenhouse gasses as additive, but it is impossible to absorb more than 100% of all emitted energy for a given wavelength. This leads to an overestimation of absorption when 2 or more gases are present. For example, if CO2 absorbs 90% of available energy at 13 μm and water vapor another 50%, the sum is 90% + (1 -0.9} * 0.5 = 95%, not 140%. To see more how the calculations are made, see here.
We have valid satellite data from 1979, and they give very good global averages. so as a test I took a quick look at the temperature rise from 1980 to 2022 and compared what the rise would be, if all greenhouse and other factors would add up to, and to my surprise the result came within 4% of real data, see here.
Between 2022 and 2050 CO2 concentration is expected to increase from 415 ppm to 460 ppm and Methane from 1.9 ppm to 2.23 ppm. these are the most important greenhouse gases after water vapor. The calculations are here.
Extended to 2100 IPCC has given 4 scenarios for future temperature development. RCP 8.5 assumes that all future energy growth is provided by fossil fuel, and at least most nuclear energy is phased out. the 8.5 stands for W/m2 for CO2 increase as per IPCC calculation. See further here.
RPC 6 and RPC 4.5 are intermediate stages , while RPC 2.6 achieves net CO2 decline by 2100, but still rising temperature. Here is a figure for the different scenarios.

The temperature data from 1980 to 2022 is the control group, and is based on real data.It was then the basis for doing the 2022 to 2050 calculation assuming no mitigation efforts, the most likely result if none of the Paris accord is implemented. The climate target is to stay under + 1.5 C, and this model, that worked better than 95% accurate between 1980 and 2022, comes up with a temperature rise of 1.28C, well below the 1.5C maximum rise since the 1800s
