For the increase of 5 % which parameter produces the largest change in mean global temperature? (geo.umass.edu)
Would a higher or indeed lower absolute mean global temperature now affect this forcing as temperature increased due to CO2 in the future or is the effect minimal. (realclimate.org)
And yet, as James Hansen, the head of NASA's Goddard Institute for Space Studies, observes, «the five - year mean global temperature has been flat for a decade.» (kottke.org)
