The last time Earth was free of ice was more than 34 million years ago, in the Eocene epoch. Alligators swam in Arctic swamps. But the planet slowly cooled as carbon dioxide rained from the air and was locked up in seafloor sediments. Continental ice sheets formed first in Antarctica, but over the past few million years they?ve repeatedly surged across northern continents too. We?re living in a warm interglacial period?20,000 years ago Chicago, New York, and London were buried under ice.

Geologically speaking the little bit of so-called warming we have now is neither unprecedented nor significant. It has been much warmer in the geologic past and life thrived on the planet. It has even been warmer in this current interglacial and humanity thrived. It takes a special kind of detachment from reality to make the case that cold is preferable to warm and that we have any control over it either way.
