Ok stupid question time. The temperature during the Cretaceous was on average hotter than the 3.9C increase stated to halt photosynthesis. There was certainly photosynthesis going on then, how is that possible? Do we assume the plants had enough time to adapt to that new temperature, changing their photosynthetic machinery to work at higher temperatures than today?

we found that tropical forests can withstand up to a 3.9 ± 0.5 °C increase in air temperatures before a potential tipping point in metabolic function
Not that close, fortunately. There are tons of other terrible disasters that will strike before we reach this point.

So the research on this article is already 2 years old, but only now was it published…
If you look at the peer review file, you'll see that they spent a year improving the paper after sever critical criticisms were made by the reviewers. They've collected more data and entirely redid the analysis. It's a different paper now compared to their first manuscript of 2021.
