US climate pact pullout could add 0.3 degrees of warming: UN

US climate pact pullout could add 0.3 degrees of warming: UNThe US withdrawal from the Paris climate pact could “in a worst case scenario” add a 0.3 degree Celsius rise in global temperatures over the 21st century, the UN said Friday. The head of the World Meteorological Organization’s atmospheric research and environment department, Deon Terblanche, underscored however that the likely impact of US President Donald Trump’s widely-condemned decision remains far from clear. “We haven’t run new models overnight but the indications are that it could be in the worst case scenario in the order of 0.3 degrees Celsius,” Terblanche told reporters in Geneva, referring to a possible rise over pre-industrial temperatures.
