This NASA Visualization Should Erase Any Lingering Doubts About Global Warming

NASA's eye-opening visualization Six Decades of a Warming Earth shows how the average global tempure has risen since 1950.


A visualization produced by NASA shows how global temperatures have risen from 1950 through the end of 2013.  Titled "Six Decades of a Warming Earth," it shows a running five-year average global temperature, as compared to a baseline average global temperature from 1951-1980, clearly revealing a long-term trend of rising global temperatures



NASA's Goddard Institute for Space Studies (GISS), which analyses global surface temperatures on an ongoing basis, recently reported that the average temperature in 2013 was 58.3 degrees Fahrenheit , over a degree warmer than the mid-20th century baseline, which means 2013 is tied for seventh place (along with 2006 and 2009) as with warmest years since records have been kept, starting in 1880.


 The warmest years in the 134-year record were 2005 and 2010, and since 2000 we've experienced 9 of the 10 warmest years.


Said GISS climatologist Gavin Schmid about the finding, "Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change."
