Global warming is real

Results just released, the Berkeley Earth Surface Temperature study finds reliable evidence of a rise in average world land temperature of approximately 1°C since the mid-1950s. This corroborates prior studies by NOAA, NASA, and the Hadley Center who found that land warming was about the same over this period and that urban heat island effects and poor station quality did not bias results (as claimed by skeptics).
