I find the article’s quoting of Hausfather deceptive, particularly the part about not being well supported by the literature. I don’t think Hausfather thinks Hansen is wrong at all. I think he wants more data confirming Hansen’s findings. I read a lot of climate literature, and I have not seen any data that contradicts Hansen. If anything, 2023 seems like an even more rapid acceleration over what has been previously observed. This is the chart that scares the crap out of me:
It takes an incomprehensible large amount of energy to heat the ocean and in 2023 the amount of heat it is storing jumped to an entirely new level. I think Hansen has to be correct for that to have happened.
