Wondering where I should try to move to... Will there actually be any safe spots on earth in a few decades?

Because the conclusions of any given paper are the same "Climate change is worse than we thought in some new way, it's caused more by human activity than we thought, we're all going to die even sooner than we thought, and if there's any chance to avert catastrophe it's in turning over control of all energy usage to boards of people like me who will be stewards for the common good." If this is true, we've already heard and we don't need any more. If it's false, it's even more useless.

Yes and they understand identifying as African American or native when you aren't really is consequence-free. Conservatives can mock Elizabeth Warren all they want, her progressive supporters don't care that she is a fake Indian.

So your claim is "Iran has the bomb but it is useless to them".
So why did they build it? Is it just a stepping stone to the hydrogen bomb?
Also, it is not widely claimed that Iran has bombs, which would require some explanation. Does Mossad know? If yes, then why do they not make that claim? How can it be both in Israel's and Iran's interests to keep the world in the dark? If not, then how were they able to hide it?
Does the US know? Am I supposed to believe that Trump could avoid blabbering about it? Was Trump's bombing targeting finished bombs, or was it just a charade and if so for whose benefits?
that the half-ton of 60% HEU could have be easily boosted to weapons grade by removing the third of lighter uranium atoms from it (it'd only take days)
This seems plausible. 400kg of 60% U-235 corresponds to roughly 240kg pure U-235. If you start from natural uranium, you would have needed to process 34 tons to get that much U-235. If your bottleneck are centrifuges rather than raw uranium and fluorine (which seems likely), you will likely have processed twice that much because squeezing out the last 0.1% of U-235 is just not worth it.
Naively, I would expect that separation efficiency is proportional to the product of the fraction of both species, so the easiest percentage gain is going from 49.5% to 50.5%. However, you do not have to go back to 99.3%, because 85% is enough for a weapon. Plus you are dealing with much less material.
(Actually, the WP article on SWU contains the relevant formula. Producing 400kg 60% enriched U takes at least 34t SW. Splitting that into 140kg 85% and 260kg 46% takes about 140kg SW, or just 0.4% of the total separation work. Even separating it to the point where your tails are just 0.7% again will just take 1.3t SW.)
There is still some overhead, probably. Perhaps the Uranium is not stored as UF6 but in a more reduced form, and it certainly will take processing after it is sufficiently enriched. The mechanics of a bomb can be prototyped with depleted uranium, but at the end of the day you either need to test your device or trust your computer models. With regard to the latter "someone falsified a fission cross-section in literature" seems like an unlikely story, but so does "someone hacked the air-gapped Iranian centrifuge network".
A common thread I saw on the gazanow telegram channel (now deleted) was that Hamas was uploading their livestream of civilian massacres not for goreporn likes, but to prove the IDF was a hollow shell without the USA and that the entire rotten edifice was kicked open so the rest of the arab world, especially West Bank but Hezbollah and Syria too, could roll in to clean out the yahudi with no effort. I still don't know if this was a particularly inspired attempt to justify the gleeful livestreamed executions and rape aftermaths as serving some strategic reason, or if it was a sincerely held belief that Israel was nothing without the USA and Hamas had struck the singular crippling blow, or y'know, both.
The one thing that really baffles me is whether Hezbollah also failed to reign in its own militants itching for action given their lack of full greenlight from Tehran or likely Nasrallah himself. For all its failures and cosplaying at being a fighting force (uniforms for nasheed tiktoks, journalist vest for publishing in reuters, the senior Hezbollah leadership must have known that keeping its cards in reserve for any Israeli incursion was the right play no matter what Hamas did.
Maybe trading bodies for international sympathy could work as a viable end state wild card, but previous trends don't really bear it out. The intifadas didn't result in a materially improved ground condition for the Palestinians and for all the hatred Israel gets it still has a growing population and economy. If that is losing for Israel, I'm sure Israel will collapse immediately like most of the world wishes it would.
