1972 prediction about amount of global heating
mercredi 19 mars 2014 à 13:00A prediction about the amount of global heating, made in 1972 based on very simple physics, corresponds to today's observations.
Nonetheless, the effect of adding further CO2 to the atmosphere is not so easy to predict. The further we go, the more possible positive feedback effects there are that might trigger further releases of CO2, or methane from warming tundra or sea bed.
