Last year’s Earth temperature was the second warmest on record
By Frederick H. Lowe
If you frequently mopped the sweat from your brow, from the back of your neck and from your forearms with a handkerchief last year, there was a good reason for it.
Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by scientists at NASA’s Goddard Institute for Space Studies, which is based in New York.
Temperatures globally averaged 0.90 degrees Celsius or 1.62 degrees Fahrenheit, warmer than the 1951 to 1980 mean, NASA reported. Last year’s scorching temperatures were second only to 2016.
The heatwave continues the planet’s long-term warming trends.
GISS does not show absolute temperatures; instead, it showed how much warmer or cooler each region of Earth was compared to a baseline average from 1951 to 1980.
Earth’s average surface temperature has risen a little more than 1 degree Celsius or about 2 degrees Fahrenheit during the past century because of carbon dioxide and other human-made emissions sent into the atmosphere.
NASA’s GISS team assembled its analysis from publicly available data from 6,300 meteorological stations around the world; from ship-and buoy-based instruments measuring sea surface temperature and from Antarctic research stations.
Some 197 countries have signed the agreement.
