The Washington Post reports:
In a powerful testament to the warming of the planet, two leading U.S. science agencies Wednesday jointly declared 2016 the hottest year on record, surpassing the previous record set just last year — which, itself, had topped a record set in 2014.
Average surface temperatures in 2016, according to the National Oceanic and Atmospheric Administration, were 0.07 degrees Fahrenheit warmer than 2015, and featured eight successive months (January through August) that were individually the warmest since the agency’s record began in 1880. NASA actually found a bigger leap upward of temperatures in 2016, measuring the year as .22 degrees Fahrenheit warmer than the prior year.
The average temperature across the world’s land and ocean surfaces was 58.69 Fahrenheit, or 1.69 degrees above the 20th century average of 57 degrees, NOAA declared. The agency also noted that the record for the global temperature has now successively been broken five times since the year 2000. The years 2005 and 2010 were also record warm years, according to the agency’s dataset.
NASA concurred with NOAA, also declaring 2016 the warmest year on record in its own dataset that tracks the temperatures at the surface of the planet’s land and oceans, and expressing “greater than 95 percent certainty” in that conclusion.
