United Nations concedes that Earth has lost its chance to prevent some of the worst impacts of global warming. Decades of weather related disasters, rising sea, melting ice, extinctions are inevitable.
Earth is soon going to exceed the safe temperature threshold agreed upon by the world in the 2015 Paris climate accord because of warming from the burning of coal, oil and gas, according to a bleak first-of-its-kind report issued by the United Nations Environment Programme Wednesday.
Instead of giving up, scientists and U.N. officials recommend trying to limit excessive warming and then bring the temperature back down to the agreed-upon threshold. But it still will mean decades of increased weather-related disasters, rising seas, extinctions and melting ice and glaciers.
“It's a reality check. We have to live with this warmer world,” said report co-author Richard Betts, a climate scientist at the University of Exeter. “But there's still a lot we can do to limit warming.”
After the Paris climate accord, the United Nations ordered its climate science arm to study different warming limits. A goal of 1.5 Celsius (2.7 Fahrenheit) above mid-19th century temperatures became generally accepted after the scientists found dramatic impacts that affect people and the planet at 2 degrees Celsius (3.8 degrees Fahrenheit) but not at 1.5 degrees.
The world is now at 1.4 C (2.5 F) above pre-industrial levels, some scientists have calculated. The measure is based on a 20-year average, rather than a single year's temperatures.
