Trump has referred to climate change as a "hoax" and in 2017 pulled the United States out of the Paris accord that laid out an worldwide approach to global warming, while Biden says climate change is on his list of major crises facing the United States.
Trump sparred with officials during his visit to California Monday over the cause of the wildfires and the best course moving forward to prevent them. Mr Trump responded: "It'll start getting cooler".
Biden, in an outdoor speech near his home in Wilmington, decried Trump's refusal to acknowledge the scientific underpinning of the climate crisis as "unconscionable" and said the USA leader had failed to protect the country from the "ravages of climate change".
Crowfoot said, "I wish science agreed with you".
While counterattacking Trump's unfounded assertion that Biden would "abolish" the suburbs if elected president, Biden mentioned wildfires burning the suburbs in the West, floods wiping out suburban neighborhoods in the Midwest and hurricanes "imperiling suburban life" along the country's coasts, in a warning against the dire long-term consequences of the President's reluctance to acknowledge climate change.
"We need a president who respects science, who understands that the damage from climate change is already here", Mr Biden added, presenting the opportunity to battle global warming as a necessary choice for Americans.
"If you give a climate arsonist four more years in the White House, why would anyone be surprised if we have more of America ablaze?" he said in a speech in Wilmington, Delaware.
"We can commit to doing this together, because we know that climate change is the existential challenge that is going to determine our future as a country". President Trump can try to deny that reality, but the facts are undeniable.
The former vice president has proposed a sweeping proposal that calls for the United States to achieve a carbon-free power sector by 2035 and make a $2 trillion investment over his first four years in office in green energy and infrastructure to combat the threat of climate change.
In an exchange with California's Secretary for National Resource during a briefing on the wildfires across the state, Mr Trump hit back at climate change arguments. "They become really like a match stick", he said.
But at the briefing, California Governor Gavin Newsom, a Democrat, countered that the fires are driven mostly by global warming.
The president has suggested that poor forest management has much to do with igniting the fires.
"But one thing is fundamental, 57 percent of the land in this state is federal and three percent is state forests", he said.
But he said the overwhelming cause of the problem is far bigger.
"The hots are getting hotter, the dries are getting drier", he said. "Something has happened to the plumbing of the world. and we submit the science is self evident that climate change is real".
Drone footage showed hundreds of homes reduced to ashes in the southern OR communities of Phoenix and Talent, around 8km (5 miles) south of Medford last week, after a wind-driven firestorm raced north, blowing embers into trailer parks and residential subdivisions.
Governor Kate Brown, along with state fire and emergency officials, presented their fourth wildfire update since the blazes started last week, and the news is both promising and disturbing.
