Countries must ramp up climate pledges by 80 percent to hit key Paris target, study finds

The pledges countries made to reduce emissions as part of the 2015 Paris agreement are woefully inadequate, and the world must nearly double its greenhouse gas-cutting goals to avoid the most catastrophic effects of climate change, according to research published Tuesday.

“The commitments are not enough,” said Adrian Raftery, a University of Washington statistics professor and co-author of the study, published in Communications Earth & Environment.
