Donald Trump has cancelled NASA’s greenhouse gas monitoring system, prompting concern it will hinder efforts to bring down global emissions.
"If you cannot measure emissions reductions, you cannot be confident that countries are adhering to the [Paris climate] agreement," Kelly Sims Gallagher, director of Tufts University's Centre for International Environment and Resource Policy, told Science Magazine.
Stephen Hagen, a senior scientist at Applied GeoSolutions in New Hampshire, said scrapping the system was “disappointing”.
Mr Trump has called climate change a "hoax" in the past - one perpetrated by the Chinese.
