The research team has, for the first time, discovered a close association between Earth climate and extinctions in a study that has examined the relationship over the past 520 million years – almost the entire fossil record available.
Matching data sets of marine and terrestrial diversity against temperature estimates, evidence shows that global biodiversity is relatively low during warm ‘greenhouse’ phases and extinctions relatively high, while the reverse is true in cooler ‘icehouse’ phases.
Moreover, future predicted temperatures are within the range of the warmest greenhous
