Figure 1.

Unequivocal evidence for a warming planet. Global surface temperature trend from three global datasets: NOAA (NCDC Dataset), NASA (GISS dataset) and combined Hadley Center and Climate Research Unit of the University of East Anglia (UK) (HadCRUT3 dataset). The data clearly indicate a dramatic, and accelerating, warming trend over the past 150 years. Reproduced from the World Meteorological Organisation [ webcite].
