Clues Found That Earth May Have a Thermostat Set to “Habitable”. Weathering of rocks can control Earth’s temperature over geologic timescales, new geochemical data suggest.

(6 September 2017)

Scientists have long speculated on the possibility of a planetary thermostat keeping climate change in check. A new study published in the journal Geochemical Perspectives Letters provides the first-ever evidence of its existence.
