Firefighters in the state have not seen anything like this season in more than a century, when the Great Fire of 1910 blazed through more than 3 million acres.
Confronting the worsening conditions of climate change, and the still more risky conditions to come, has "critical relevance for ongoing efforts to manage wildfire risks in California and other regions", the researchers wrote.
Democratic politicians on the US West Coast have accused President Donald Trump of being in denial about climate change's role in the huge wildfires there, before his visit to California.
The president is scheduled to deliver remarks to the California National Guard, but first he will meet with the governor and emergency response officials for a briefing, according to reports.
Biden, who is to give his climate speech in DE on Monday, released a $2 trillion plan in July to boost investment in clean energy and stop all climate-damaging emissions from USA power plants by 2035.
Trump, who will be briefed during a stop near Sacramento before a campaign visit to Phoenix, has been mostly quiet as the catastrophe on the West Coast has unfolded over the past few weeks.
At least 10 people have been killed in OR in the past week.
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".
The Oregon Office of Emergency Management said on Sunday that firefighters in the state were struggling to contain more than 30 active wildfires - the largest of which was more than 89km (55 miles) wide. "Please respect the difference of opinion out here with respect to the fundamental issue of climate change", he said.
She added: "This is a wake-up call for all of us that we've got to do everything in our power to tackle climate change".
But he insisted the blazes were "about forest management", which includes tree thinning and brush clearing.
The smoke created cooler conditions in OR as well.
But, the governor said, all of those problems have been intensified by drought that climate change has worsened.
The Governor of Washington State, Jay Inslee, has acknowledged that "there are places where it makes sense that we thin our timber".
California and 19 other states on Monday filed a lawsuit challenging the Trump administration's decision to weaken curbs on methane emissions from the oil and gas industry, saying the widespread West Coast wildfires should be a reminder of the dangers posed by climate change.
An analysis out in August from Stanford climate and wildfire researcher Michael Goss and others found that a almost 2-degree (1 Celsius) rise in autumn temperatures and 30 percent drop in rainfall has more than doubled the number of autumn days with extreme fire weather over the past 40 years. All of the state's forests are classified as being in "extreme fire danger".
Two new deaths were confirmed from the North Complex Fire, which swept at unprecedented speeds this week into areas already ravaged less than two years ago by the Camp Fire - California's deadliest ever blaze.
However, there are questions about whether enough resources are being devoted to this, and if it's really come too late in the day to prevent major fires.
In terms of loss of life and damage to property, the data shows the worst fires have all been in the past 10 years or so - except for one fire in 1991 in Alameda County.
Across California, Oregon and Washington almost 100 wildfires have burned 4.5 million acres of forest. Long lines of cars stretched in front of them, waiting in thick fog to pass through.
