Abstract: Global mean surface temperatures have risen by 0.74C ± 0.18C when estimated by a linear trend over the last 100 years (1906-2005). The rate of warming over the last 50 years is almost double that over the last 100 years (0.13C ± 0.03C vs. 0.07C ± 0.02C per decade). Global mean temperatures averaged over land and ocean surfaces, from three different estimates, each of which has been independently adjusted for various homogeneity issues, are consistent within uncertainty estimates over the period 1901 to 2005 and show
similar rates of increase in recent decades. The trend is not linear, and the warming from the first 50 years of instrumental record (1850-1899) to the last 5 years (2001-2005) is 0.76C
± 0.19C. [...]
