56 million years ago, the Earth suddenly heated up – and many plants stopped working properly
It could be a sign of what’s to come.

We are still trying to figure out exactly how much "safe(ish) space" we still have with athmospheric CO2 to keep temperatures in the "suitable for human habitation" zone. This study tries to narrow it down: between 251 and 666 Gt.🧪
