Hadley Centre: Average 4 C Warming Could Happen Within a Human Lifetime, With Even Greater Warming in Many Regions
Green Car Congress
SEPTEMBER 28, 2009
Comparison of surface temperature projections from the high-end emissions scenario, without carbon cycle feedbacks. If carbon cycle feedbacks are strong then a 4 degree warming could occur even earlier. Temperature increases between 1961-1990 and 2090-2099, averaged over all high-end members. Source: Met Office.
