Human-caused climate change doubled the likelihood of the tinderbox weather conditions that sparked Canada’s massive summer wildfires and in turn angered U.S. President Donald Trump, according to a study released Thursday.
And fire and climate scientists said Trump, who has talked about punishing Canada for poor fire management and sending days of choking smoke across the border, should look more in the mirror than up north when it comes to blame. They point to the United States' huge historical emissions of heat-trapping gases from the burning of coal, oil and gas.
