Global warming: Atmosphere to warm by at least another 2 degrees

(USA TODAY) August 6, 2017 — We’re cooked.

A scientific study released Monday said that the Earth’s atmosphere will warm by at least another 2 degrees C (3.8 degrees F) — regardless of what we do in the future to limit greenhouse gas emissions.

There’s only a 5% chance that Earth will warm 2 degrees or less by the end of this century, the study said. It shows a mere 1% chance that warming could be at or below 1.5 degrees, which was the target set by the landmark 2016 Paris Agreement.

“Our analysis is compatible with previous estimates, but it finds that the most optimistic projections are unlikely to happen,” said study lead author Adrian Raftery of the University of Washington. “We’re closer to the margin than we think.”

The study was published in the peer-reviewed British journal Nature Climate Change.

The burning of fossil fuels such as gas, oil and coal is causing the planet to warm to levels that cannot be explained by natural factors, scientists say.
