It is a complete fraud to say Sanders, Warren, AOC, Tuneberg etc have said such a thing. They're referring to the UN scientists who say that we'll be passing a point of no return ecologically to repair the damage we've done. It's not the Earth that's in trouble, it's the humans and other life on the earth that's in trouble.

Fact-check: Five claims about thorium made by Andrew Yang
By John Krzyzaniak, Nicholas R. Brown, December 18, 2019
Overall, although existing and new nuclear reactors may indeed be part of a long-term carbon-free energy mix in the United States, the public has good reason to be skeptical that thorium can or should play any role in the future.

If you are referring to the IPCC, which I assume you are, they will be removing the RCP8.5 scenario from AR6. If you don't understand that then your contribution is entirely worthless and can safely be discarded.

Not removing, but updating with new data sets. That doesn't really change the nature of the problem in a no mitigation scenario. https://www.carbonbrief.org/explaine...rming-scenario

The 2018 National Climate Assessment used RCP8.5 to scare the scientifically illiterate, it's actually very doubtful that even RCP6.0 is a realistic scenario either. This masterpiece in deception and magic thinking was entirely the product of the Obama era, the next will far more sanguine and rooted in reality. I suggest that you read this excellent discussion on Dr. Roy Spencer's blog.

There are so many people that think nuclear waste is useless and cannot be reused. This is not true but sadly that message doesn't seem to get through to leftist idiots like BitchyLibBoreAll.

SAFE AND SECURE USED FUEL MANAGEMENT SYSTEM
What you normally hear about as nuclear waste is actually the “used fuel” removed from a reactor, which still contains approximately 96 percent of the original fuel that can be recovered to produce new fuel. This used fuel is currently stored in pools of water or in robust containers on a concrete pad (dry cask storage).
All the used nuclear fuel produced by the nuclear energy industry in nearly 60 years—if stacked end to end—would cover an area the size of a football field to a depth of less than 10 yards. The NuScale power plant design includes a proven safe and secure used fuel management system.
Used fuel management, storage, and disposal are regulated by U.S. Nuclear Regulatory Commission (NRC) and the U.S. Department of Energy (DOE) has responsibility for its ultimate disposal. In addition, recycling used fuel could significantly reduce the burden of mining and disposing of spent fuel, making our nuclear fuel cycle more sustainable.
USED FUEL MANAGEMENT AT A NUSCALE PLANT
NuScale reactor building and plant design incorporates a proven safe, secure and effective used fuel management system. A stainless steel lined concrete pool holds used fuel for at least 5 years under 60 feet of water. The used fuel is protected both by the ground and the Seismic Category 1 reinforced concrete reactor building designed to withstand an aircraft impact, and a variety of natural and man-made phenomena.
USED FUEL STORAGE AND DISPOSAL
After cooling in the spent fuel pool, spent fuel is placed into certified casks, steel containers with concrete shells, on site of the plant. The NRC Waste Confidence Rule states that this is a safe and acceptable way to store used fuel for an interim period at the plant up to 100 years. The NuScale’s standard facility design includes an area for the dry storage of all of the spent fuel for the 60-year life of the plant.
The U.S. Department of Energy (DOE) has responsibility for the final disposal of used fuel under the Nuclear Waste Policy Act. Under the Act, the generators' of electricity from nuclear power must pay into a fund for the long term disposal of this used fuel; over $35 billion is currently in the Nuclear Waste Fund.
USED FUEL RECYCLING – A BETTER OPTION?
Recycling used fuel could significantly reduce the burden of mining and disposing of spent fuel, making our nuclear fuel cycle more sustainable and further reducing the already-low carbon total footprint of nuclear power.
KEY FACTS
96 percent of the content of the used fuel is reusable energy
Recycling used fuel:
Saves 25 percent of natural uranium resources
Reduces the volume of high-level waste slated for disposal in a repository by 75 percent
Reduces the waste’s toxicity by about 90 percent
Source: AREVA
Recycled fuel, or mixed uranium-plutonium oxide (MOX) fuel, is a suitable fuel for the NuScale reactors. Recycling has been in successful use in several markets, such as France, for decades. Also, there are next generation designs that can utilize this used fuel in its reactors as a means to reduce the overall quantity.

More about Thorcon thorium based molten salt reactors.
https://www.forbes.com/sites/jamesco.../#3efd0cb27694ThorCon Advanced Nuclear Reactor -- More Than Worth Its Weight In Salt
It’s been 30 years since America built a really new nuclear power plant, but we haven’t been idle over this time. A slew of new designs have emerged and, thanks to advances in computing capabilities and the understanding that smaller is better, many of these are ready to be built economically.
This is important. Over the last several years, there has been a growing consensus among climate scientists that nuclear energy is critical for mitigating the worst effects of global warming. States are shifting from Renewable Energy Mandates to technology neutral Clean Energy Standards that include nuclear energy.
So it is good that the development of new nuclear technologies is speeding along faster than most people think. Many new nuclear start-up companies have emerged in the United States, China and Canada, especially those designing small modular reactors (SMRs).
Importantly, all are walk-away-safe, which means the reactor just won’t melt down or otherwise cause any of the nightmares people think about when imagining the worse for nuclear power. It just shuts down and cools off.
Canadian Nuclear Laboratories announced SMR technology as a research priority and Canada now has a roadmap for them, and has vowed to build an SMR demonstration plant on their site by 2026.
China is also moving fast on its Linglong One 100 MW SMR with its first use to generate heat for a residential district, replacing coal-fired boilers.
While some SMR designs are based on the traditional light water reactor that uses slightly enriched uranium, others involve molten salt and other fuels such as thorium and thorium+uranium.
One such reactor is ThorCon, a fission reactor with a liquid molten salt fuel containing thorium+uranium. A full-scale 500 MW ThorCon prototype should be able to be built and operating within four years.
Molten salt reactors are not completely new. The United States successfully conducted a Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory in the 1950s.
Irradiation tests on a mixture of lithium and thorium fluoride salts are under way at the High Flux Reactor at Petten in the Netherlands. Terrestrial Energy is also developing an Integrated Molten Salt Reactor.
But the ThorCon takes a different tack on manufacturing. It would be completely manufactured in 150 to 500 ton blocks in a shipyard, assembled, then towed to the site, producing order of magnitude improvements in productivity, quality control, and build time.
ThorCon’s genesis is in ship production, one of the few industries up to snuff for building large complicated technologies. The Hellespont Fairfax, the largest double hull tanker ever built, is one of eight ships built by ThorCon’s predecessor company. She was built in less than 12 months and cost 89 million dollars in 2002.
ThorCon is designed to bring shipyard quality and productivity to fission power. But ThorCon’s structure is simpler and much more repetitive than a large ship. The fission island employs steel plate, sandwich walls filled with concrete or sand. This results in a strong, air-tight, ductile building, all simple flat plate. A properly implemented panel line will be able to produce these blocks using less than 2 man-hours per ton of steel.
Each ThorCon plant is based on one or more hulls, each containing two 250 MWe power modules, a 500 MW super-critical turbogenerator, gas insulated switchgear (GIS), a decay heat pond, and auxiliaries (see figure above). The fission island is at the forward end of the hull. Aft of the fission island is the Steam Generating Cell (SGC). Aft of the SGC is the turbine hall, which contains the turbogenerator, exciter, condensers, feedheaters, pumps, and condensate treatment.

He extols the virtues of Castro, Socialism and Communism. Many in the Democrat Party do so also.
These are dangerous people.
He will never be allowed to be the nominee. The radical Democrat Socialists are falling off a cliff but they haven’t hit bottom yet.
Where is Nervous Nancy? She seems to have disappeared.

Good information.

Spencer includes an update link that says "Will nature continue to remove 2.0-2.3%/yr of the CO2 excess above 295 ppm, or will that removal rate drop precipitously? If it stays fairly constant, then the future RCP scenarios are overestimating future atmospheric CO2 concentrations, and as a result climate models are predicting too much future warming."
There is good reason to think, given the massive forest fires in the US and Brazil, and the continual warming of the ocean releasing more CO2 - that the earth will have less removal capacity in the future.
I don't see him really refuting any of the data or the overall imprtance of addressing the problem, he seems to be more criticizing how wide spread and out of context the model has become. It's a worst case scenario given no action on climate change. It's still something to be aware of.Hausfather has been one of the most vocal climate alarmists so it's big news that he's now woken up.

I think Bernie's opposition to fracking is the least of his problems, Tom. The DEMOCRAT Faithful are desperately trying to cheat him out the nomination again, by any means necessary.
He's too honest about what DEMOCRATS really want to accomplish, and they fear that means they will lose again.

The methane released by fracking is 30 times heavier than carbon emissions, because methane is a heavier gas.
