BEST

Land temperatures from 1750-2000.  The shaded regions show the statistical uncertainties. Prior land results from the other research groups are also plotted.

An IPCC-independent study, the Berkely Earth Surface Temperature (BEST) has confirmed global warming! The research team analyzed land-surface temperature data from 36000 meteorological stations going back to 250 years where it was possible, about 100 years further than previous studies. Temperatures have rised in 2/3 of the stations, 1/3 indicated a cooling. The Urban heat island effect, a frequently cited argument of the so called climate skeptics is negligible and gives no explanation about.
