The verdict is in — record breaking weather extremes around the globe are increasing as a result of human-made carbon pollution. But there is good news. The latest research shows we can transition to clean, renewable energy sources while supporting healthy, sustainable economic development. There’s only one climate. Let’s work to reverse global warming and bring the climate back into balance, so generations to come have a safe planet to call home.

NASA: Five-Year Average Global Temperature Anomalies from 1880 to 2010*
*White represents “zero anomalies” compared to normal surface land and water temperatures (based on average of 30 years 1951-1980). Groups of scientists from several major institutions — NASA’s Goddard Institute for Space Studies (GISS), NOAA’s National Climatic Data Center (NCDC), the Japanese Meteorological Agency and the Met Office Hadley Centre in the United Kingdom — tally data collected by temperature monitoring stations spread around the world and make an announcement about whether the previous year was a comparatively warm or cool year.
This analysis concerns only temperature anomalies, not absolute temperature. Temperature anomalies are computed relative to the base period 1951-1980. The reason to work with anomalies, rather than absolute temperature is that absolute temperature varies markedly in short distances, while monthly or annual temperature anomalies are representative of a much larger region. Indeed, we have shown (Hansen and Lebedeff, 1987) that temperature anomalies are strongly correlated out to distances of the order of 1000 km.
