Earth’s temperature changes in the last century-and-a-half, analyzed within 30 seconds in a video

Earth continues to increase its temperature. According to NASA scientists, the 10 warmest years in the 134-year record have all occurred since 1998, with 2010 and 2005 ranking as the warmest years. The average global temperature in 2013 was 14.6 °C (58.3 °F), which is 0.6 °C (1.1 °F) warmer than the mid-20th century.

The following video shows a color-coded map which represents how Earth’s surface temperature has changed from 1880 to 2013: red colour denotes higher-than-normal temperatures and blue colour denotes lower-than-normal temperatures.

The temperature analysis done by GISS is compiled from weather data from more than 1 000 meteorological stations around the world, satellite observations of sea-surface temperature and Antarctic research station measurements, taking into account station history and urban heat-island effects. Software is used to calculate the difference between surface temperature in a given month and the average temperature for the same place from 1951 to 1980.
