Unfortunately, it isn’t about what humans can tolerate. We can definitely tolerate fluctuations in natural climate changes, we have before and will again. it’s the crops that can’t, and therein lies the problem.

I never understood the term “fight climate change”. There’s no fighting the weather and natural weather cycles and rhythms, rather we should be working with what we know about climate cycles, planting different crops, rotating them in different areas of the country as it generally gets colder for a while (years? Decades? A few centuries?). We survived a mini Ice Age before. We went from planting grapes in England during the warming phase, to ice-skating on the Thames when the entire river froze on the regular.
