Know a Climate Change Denier? Show Them This Video!



This is a video from NASA. You know the National Aeronautics and Space Administration? They’re kind of experts on this stuff.

This is a very short (13 second) animation that illustrates how temperatures around the world have warmed since the 1950s. You’ll note accelerated temperatures trending 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 comes from NASA’s Goddard Institute for Space Studies in New York (GISS), which monitors global surface temperatures. As NASA notes, “All 10 of the warmest years in the GISS analysis have occurred since 1998, continuing a trend of temperatures well above the mid-20th century average.”

So bookmark this one and show it to your grumpy aunt that denies climate change at your next family gathering! You might be surprised at her reaction and that of any other friends who might be a climate change deniers.
