Watch 60 years of global warming in 15 seconds

NASA has released a new visualization showing how global temperatures have risen since 1950. It's pretty much what you'd expect given that the level of carbon dioxide in our atmosphere is currently higher than at any time in the last 800,000 years.

This visualization was put together by NASA's Goddard Institute for Space Studies (GISS). The group, which analyzes global surface temperatures on an ongoing basis, just released a rather sobering report on temperatures around the globe in 2013.


NASA says 2013 is now tied with 2009 and 2006 for the seventh warmest year since 1880. So, discounting 1998, the ten warmest years in the 134-year record have all occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.

The updated data shows that average temperature in 2013 was 58.3 degrees Fahrenheit (14.6 Celsius), which is 1.1 F (0.6 C) warmer than it was at the mid-point of the 20th century. The average global temperature has risen about 1.4 degrees F (0.8 C) since 1880.


From NASA:

The carbon dioxide level in the atmosphere was about 285 parts per million in 1880, the first year in the GISS temperature record. By 1960, the atmospheric carbon dioxide concentration, measured at the National Oceanic and Atmospheric Administration's (NOAA) Mauna Loa Observatory in Hawaii, was about 315 parts per million. This measurement peaked last year at more than 400 parts per million.

While the world experienced relatively warm temperatures in 2013, the continental United States experienced the 42nd warmest year on record, according to GISS analysis. For some other countries, such as Australia, 2013 was the hottest year on record.
