Thicken its CO2 blanket, and Earth overheats. Featured
Notes: CO2 and other greenhouse gases trap heat radiating from the earth, much as a blanket traps the heat radiating from your body at night. Without CO2, earth would be frozen and uninhabitable, like Mars. At the other extreme, way too much CO2 would turn earth into a furnace, like Venus.
Earth's unique balanced atmosphere makes life possible.
