Without this greenhouse effect, the average surface temperature would be 255 degrees kelvin (-18 degrees Celsius or 0 degrees Fahrenheit); a temperature so low that all water on Earth would freeze, the oceans would turn into ice and life, as we know it, would not exist.
The global average (land and ocean) surface temperature shows a warming of 0.85 [0.65 to 1.06] Â°C in the period 1880 to 2012, based on multiple independently produced datasets. Earth's average surface temperature rose by 7002273890000000000â 0.74Â±0.18 Â°C over the period 1906â2005.
