NASA has recently released a new global map showing the temperature changes for the 2000-2009 decade. These maps do not show the absolute temperature, but instead show how much warmer or colder a region was on average than the 1951-1980 period.
According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8°Celsius (1.4°Fahrenheit) since 1880. Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20°C per decade.
