"Global temperatures could exceed 1.5 degrees Celsius above their preindustrial levels within the next 15 years, according to a new scientific study, crossing the first threshold under the Paris climate agreement and placing the world at a potentially dangerous level of climate change.

The report comes as climate agreement participants are watching the United States — where the Trump administration is debating whether to withdraw from the Paris accord — and as scientists with the Intergovernmental Panel on Climate Change are working on a special report about the 1.5-degree goal (equivalent to 2.7 degrees Fahrenheit) and the consequences of overshooting it.

That IPCC’s upcoming special report and the increasing urgency about minimizing global warming were one impetus for the study, according to co-author Benjamin Henley, a research fellow at the University of Melbourne in Australia. “We are working on a number of scientific avenues to help inform that report,” he told The Washington Post."
