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?
