Smashing past global temperature highs, July was the hottest month on record

July was the hottest month in the 136-year history of instrumental temperature recordings, according to new data published by NASA this week.

NASA calculates the average temperature in July was 1.51 degrees Fahrenheit hotter than the average July temperature between the years 1950-1980.

NASA climatologist Gavin Schmidt also tweeted the data in a visual graph, showing July was the hottest month since instrumental recording started 136 years ago.

The previous four hottest months were all within the last four years: July 2011, July 2015, July 2009, and August 2014.

This year is also quickly outpacing last year as the hottest year ever. Blistering heat has blanketed portions of the southern United States during the record breaking July including Tampa, Florida, Fort Lauderdale Florida, New Orleans and Houston.

NASA cited last year’s El Niño as one contributor to the boost in the sweltering heat. But the scientists also contribute the long-term trend of increasing levels of carbon dioxide in the atmosphere, which has been linked to climate change.
