Thermometers don’t lie.
This summer is officially on record as the hottest three months in the Northern Hemisphere since recordkeeping began in 1880 — tied with 2016 — the National Oceanic and Atmospheric Administration revealed Monday.
“Record-warm temperatures during the three-month period were present across parts of the western coast of Alaska, Mexico, western and southern Africa, South America, Europe and Asia,” NOAA said in a statement. “Africa had its warmest June-August on record.”
This also helped shrink the Arctic polar ice cap to the second smallest coverage for the month on record, NOAA said.
The Northern Hemisphere is where 90% of the world’s population lives, USA Today noted.
The most notable aspects of the latest report, said NOAA, are the sea ice retreat, the regional record August heat in Europe, Africa and the Hawaiian region and the fact that the season was especially scorching for Africa, South America and Europe. Arctic ice was 30% below average, NOAA said and the sea ice extent was the fifth-smallest August extent on record. Africa in particular had its warmest June-August since records began, NOAA said.
Earth has been logging record high temps all summer. Planetwide, June was the hottest month on record, NASA noted earlier this summer, with temperatures 1.7 degrees higher than the norm. Likewise July didn’t fare much better, reported the Copernicus Climate Change Programme of the European Union in August.
"Climate change is the defining issue of our time and now is the defining moment to do something about it,” the United Nations said on the website introducing the climate summit happening next Monday. “There is still time to tackle climate change, but it will require an unprecedented effort from all sectors of society.”
