Study | Carbon Dioxide Levels & Global Warming 40 Million Years Ago

GreenTracker| In the complex arguments around what causes global warming and what humans should do about it is the historical, scientific reality that huge temperature changes have impacted the planet in earlier cycles of history. Humans had no direct responsibility in causing those changes.

Variations in atmosphere carbon dioxide around 40 million years ago were tightly linked to major variations in global temperature, according to new findings published in the journal Science. Authors of the new study focused on one of the hottest episodes of Earth’s climate history — the Middle Eocene Climatic Optimum (MECO), which occurred around 40 million years ago.
