Transient Dwarfism of Soil Fauna

It’s been well established that rising temperatures and CO2 levels in the environment tends to decrease animal size. But what about the keystone species and ecosystem engineers that make soil? Although there’s not been much contemporary research into this the fossil record allows us to presume upon the future of soil fauna. The Paleocene-Eocene Thermal [...]

Hyperthermal Shrinking

Global warming has the potential to shrink the human species. As we’ve discussed before mammals, and many species of birds and fish, shrink when the climate heats up. During the last two hyperthermals, the Paleocene-Eocene Thermal Maximum (55 million years ago) and the Eocene Thermal Maximum 2 (53 million years ago), temperatures rose as much as [...]
