“It’s just dead wrong, and almost 200,000 Americans are dead from this coronavirus and most of them died unnecessarily,” said the Democrat, who argued that “the impacts of the climate crisis are so much worse”.
“He’s trying to gaslight the virus, gaslight the climate system, and they are impervious to his words,” he continued.
“Really, our only hope is to get the best information available, and act to protect ourselves and our civilization in response,”
He added: “We need leadership. We have solutions available to us if we can get the politics and the misguided propagandistic messaging from the president out of it.”
Mr Cuomo had asked the Democrat whether or not the president could win November’s election with “silly” claims about the climate getting “cooler” and coronavirus “disappear[ing]”, which were made in the past week.

It comes as the United States’ coronavirus death toll approaches 200,000, with Mr Trump on Wednesday disputing a coronavirus vaccine timeline suggested by Dr. Robert Redfield, the director of the Centers for Disease Control and Prevention.
“I think he made a mistake when he said that,” the president told reporters. “It’s just incorrect information.”
Meanwhile on Monday, Mr Trump denied climate change had contributed to devastating wildfires on the West Coast, instead blaming Democratic governors and “explosive” trees, as he denied the existence of a climate crisis.
Mr Gore has endorsed Joe Biden, the Democratic presidential nominee, in November’s election.
