Gaia-hypotese

Fra Wikipedia, den frie encyklopædi

James Lovelock's Gaia-hypotese er, at Jordens levende organismer regulerer biosfæredelen, så den bliver ved med at være beboelig for organismerne selv.

Følgende kilder beskriver effekter som måske har en sådan virkning. ^{[1] [2] [3] [4] [5]}

2. ↑ The Carbon Cycle and Earth's Climate Citat: "...The Climate Buffer. Because of the role of CO2 in climate, feedbacks in the carbon cycle act to maintain global temperatures within certain bounds so that the climate never gets too hot or too cold to support life on Earth. The process is a large-scale example of Le Chatelier's Principle....some examples:..."
