In what's widely being described as the most shocking upset in U.S. election history, Donald J. Trump has beaten Hillary Clinton to become the 45th president of the U.S.
As one of the world's largest greenhouse gas emitters, any change at the top of U.S. politics warrants a consideration of what it might mean for the country's climate and energy priorities.
But given Trump's comments on the campaign trail, the U.S.'s recent reputation under Barack Obama as a nation serious about tackling climate change now looks to be in peril.
For example, Trump said he thought climate change was a "hoax" perpetrated by the Chinese. In addition, he pledged to end federal spending on low-carbon energy and to pull the U.S. out of the UN's Paris agreement on climate change. Carbon Brief has been asking climate scientists for their reactions.
