Global Annual Mean Surface Air Temperature Change

Fig A Global annual-mean surface air temperature change derived from the meteorological station network [an update of Figure 6(b) in Hansen, et al. (2001)]. Uncertainty bars (95% confidence limits) shown for both the annual and 5-year means, account only for incomplete spatial sampling of data.

Annual Mean Temperature Change for Three Latitude Bands

Fig B Annual and five-year running mean temperature changes for three latitude bands that cover 30%, 40% and 30% of the global area. Uncertainty bars (95% confidence limits) are based on spatial sampling analysis.

Global Monthly Mean Surface Temperature Change

Fig C Fig C'

.

Monthly mean global surface temperature derived from meteorological stations alone and the monthly mean land-ocean temperature index, as described in Hansen, Ruedy, Glascoe and Sato (1999). The land-ocean temperature index uses sea surface temperatures obtained from satellite measurements of Reynolds and Smith (1994).

Temperature index change since 1950 at seasonal resolution, for the globe (above) and for low latitudes [an update of Figure 10 in Hansen, Ruedy, Glascoe and Sato (1999)]. Blue semicircles mark La Ninas, red rectangles mark El Ninos, and green triangles mark large volcanos.

<<< What's New >>>

Is 2005 going to be the warmest year as we predicted? The mean temperature anomalies for the first eight months of the year are
#1 1998 (0.62°C), #2 2002 (0.59°C) and #3 2005 (0.58°C). (2005-09-09)

2005vs1998

If we compare this year's winter and summer temperatures to those of last several years, (2005-09-09)
