Global warming outpaces efforts to slow it: UN

Humanity is falling further behind in the race against climate change, with the gap between greenhouse gas emissions and levels needed to achieve the Paris climate treaty temperature goals continuing to widen, the UN said Tuesday. To cap global warming at two degrees Celsius (3.6 degrees Fahrenheit), national carbon-cutting pledges annexed to the 2015 Paris Agreement must collectively triple by 2030, according to the UN Environment Programme's (UNEP) Emissions Gap report. "The emissions gap is much bigger than last year," UNEP's Philip Drost, one of several coordinators for the annual report's ninth edition, told AFP.
