135 Years of Global Warming in 30 Seconds

  • Jan 18, 2015

This iconic animation from NASA depicts how temperatures around the globe have warmed since 1880. Note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.

The data come from NASA’s Goddard Institute for Space Studies in New York (GISS), which monitors global surface temperatures.
