The dozens of blazes that have devastated the coast for days have already killed at least 35 people since the start of the summer, including 27 this week alone in the three states of Washington, Oregon and California.
"The observed evidence speaks for itself: climate change is real and it is making fires worse", announces Gavin Newsom, the Democratic governor of California.
"It will eventually cool down," the US president later replies in an exchange with Wade Crowfoot, a local official with the California Natural Resources Protection Agency.
“I don't think science really knows,” added the Republican candidate, who regularly makes climate skepticism.
"We have a choice, we can commit to moving forward together because we know that climate change is an existential challenge that will determine the future of our country", or "we can choose Donald Trump's path: ignore the facts, to deny the reality, which amounts to giving up completely ”, nevertheless whispered Wade Crowfoot to Donald Trump.
For the American president, the cause of the fires is mainly linked to an alleged bad “forest management” in these states, controlled by his democratic adversaries.
According to the scientific consensus, the exceptional scale of these forest fires is however well linked to climate change, which aggravates chronic drought and causes extreme weather conditions.
