Absence of Clouds Caused Prehuman Supergreenhouse Periods
Description: In a world without human-produced pollution, biological productivity controls cloud formation and may be the lever that caused supergreenhouse episodes during the Cetaceous and Eocene, according to Penn State paleoclimatologists. The finding provides important insights into the interactions between the biosphere of Earth and planet's global climate. The study may also help researchers understand how modern climate change could affect the future of life on Earth. [Source: NASA - Astrobiology Magazine]
