Record high temperatures and a record fire season are hitting Canada at the same time this summer, leading to an unprecedented combination of heat, fire and dangerous smoke plumes.

“I can’t emphasize enough just how terrifying this moment is on our planet. With global temperature records breaking and fires and floods raging around the world, our house is truly on fire,” Kristina Dahl, principal climate scientist at the Union of Concerned Scientists, told CNBC.

Climate change, caused by greenhouse gas emissions, is making the planet hotter and also increasing the potency of the ingredients that are necessary for wildfires to burn. Even if humans stopped burning all fossil fuels today, the carbon dioxide already in the atmosphere is going to continue heating the planet for decades to come.

“If I had a magic wand and said, ‘no more greenhouse gases being produced from human activities as of now,’ we will continue to warm for 30 to 50 years,” explained Michael Flannigan, the research chair for predictive services, emergency management and fire science at Thompson Rivers University British Columbia.

That means what’s happening now is unprecedented, but it’s also a harbinger of what’s coming.

“This is the new reality, not the new normal, because we’re on a downward spiral,” Flannigan told CNBC.

Record-breaking wildfires with no end in sight

On June 27, Canada surpassed the record set in 1989 for total area burned in one season when it reached 7.6 million hectares, or 18.8 million acres, a communications officer for Natural Resources Canada, told CNBC.

The total has since increased to 9.3 million hectares, or 23 million acres, which is about the size of South Carolina. The average is around 2.2 million hectares, or 5.4 million acres, or about the size of Massachusetts.

“The current wildfire season in Canada has been astounding and record breaking,” Dahl told CNBC.

Soon, the total amount of land burned this year will hit the equivalent of Maine, Flannigan said.

“We’re used to getting fires in the West, or the East, or in the north, or the central — but not the whole country at the same time,” Flannigan told CNBC.

And the fire season is not even close to over. There are currently 908 active fires burning in Canada, and 576 of those are classified as “out of control,” according to data in a real time dashboard operate by the Canadian Interagency Forest Fire Centre as of 2:15pm EST on Thursday.

“I’m not sure where we’re going to end up with this because it keeps keeps on burning,” Flannigan told CNBC. “Some of these fires are huge. And they will burn all summer, all fall, and some of them will burn through winter. Underground they smolder and even though you can have snow on top, they keep burning underground. And then spring, the snow melts, stuff gets hot, dry and windy. They pop to the surface and start spreading again.”

Record heat turns vegetation into kindling

Earlier in July, the Earth recorded its hottest average day since records began — then repeated the feat three times in four days.

Temperatures in Canada are no exception. Earlier this year, Fort Good Hope, at about 66 degrees north latitude in the Northwest Territories, reached 37.4 degrees Celsius — more than 99 degrees Fahrenheit — setting a record for the warmest Canadian temperature at that latitude, according to the Canadian government. Subsequent readings in nearby communities were even hotter, according to news reports.

“We’re in uncharted waters here,” Dahl told CNBC.

“Since May we’ve seen a pattern of heat domes developing in parts of North America,” Dahl told CNBC. A heat dome is a weather event that occurs when the atmosphere traps hot air like a lid or a cap, as the National Oceanic and Atmospheric Administration describes it. “These zones of extreme heat tend to persist for long stretches of time — weeks in some cases. The heat dome that developed in May was linked to the development and spread of the fires in Alberta that kicked off the start of Canada’s record-breaking fire season.”

“I’ve never seen it start so early that far north,” Flannigan told CNBC. Before he started working in academia, Flannigan worked for the Canadian Forest Service for 30-plus years.

Hotter weather dries out vegetation, which serves as fuel for the wildfires.

“The warmer it gets, the atmosphere gets more efficient at sucking the moisture out of the fuels,” Flannigan told CNBC. “It’s not a linear increase, it’s almost exponential.”

Also, warmer temperatures lead to more lightning, Flannigan said. In Canada, about half of wildfires are started by lightning, but they are responsible for 80% to 90% of the land burned, since these areas tend to be remote and harder for firefighters to reach.

A future of more fire and smoke

Three key ingredients for a wildfire spread are fuel, ignition and weather, Sarah Burch, a climate change professor at the University of Waterloo and the executive director of the Waterloo Climate Institute, told CNBC.

“While wildfire is a natural feature of healthy ecosystems, climate change affects all three of the factors” that cause wildfires, Burch told CNBC. So, too, does land management. For example, the mountain pine beetle is killing trees and turning them into fuel for wildfires, Burch told CNBC. And long-duration droughts also make forests more flammable.

“This means that we expect fires to increase in frequency and intensity in the future,” Burch told CNBC.

People will have to learn to live alongside those wildfires.

“This is a common misconception of people that fire management can stop all fires all the time. Obviously, that’s not true,” Flannigan said.

If firefighters arrive when a fire is still small, they can put it out. But sometimes a fire can balloon into a high-intensity blaze in as little as 15 minutes. When a wildfire becomes a “crown fire,” meaning it jumps from tree top to tree top, “the horse has left the barn,” Flannigan told CNBC. “It’s too late. You’ve missed your window.”

Some fire mitigation techniques can work to slow the back end of a fire that’s already burning at full intensity, but when “that head is just racing across the landscape, you just have to get out of the way.”

This means more smoke from these wildfires traveling to other parts of the globe, too. Earlier in July, wildfire smoke from Canada blanketed much of the United States mid-west and Eastern seaboard.

There is no silver bullet to solving this problem, Flannigan says. Drones and artificial intelligence can help scientists track and monitor fire movement, but they are tools, not solutions. The only long-term solution is to reduce greenhouse gas emissions on a global scale to mitigate the effects of climate change.

“I think there’s still time if we get our act together as a global society to deal with this. And sometimes people need a bloody nose or two before we change our behavior. We can change. And I’m hoping that we’re getting the bloody noses and now we’ll actually do something about fossil fuels,” Flannigan said.

Trump to host Jensen Huang at White House as Nvidia tops  trillion market cap

Nvidia CEO Jensen Huang will meet with President Donald Trump at the White House on Thursday, CNBC’s Megan Cassella reported.

The meeting comes as Nvidia rose slightly on Thursday, becoming the first company to close a trading day with a market cap over $4 trillion, beating Apple and Microsoft to the symbolic milestone. Nvidia touched the mark briefly on Wednesday during trading.

Trump praised Nvidia stock in a social media post Thursday morning.

“NVIDIA IS UP 47% SINCE TRUMP TARIFFS. USA is taking in Hundreds of Billions of Dollars in Tariffs,” Trump posted on Truth Social. “COUNTRY IS NOW ‘BACK.'”

An Nvidia representative declined to comment, and it was unclear what the meeting is about, but Nvidia has been grappling with export controls on its artificial intelligence chips implemented by the Trump administration in April for national security reasons.

At the time, the U.S. government told Nvidia that its previously-approved H20 processor — intended exclusively for the Chinese market — would require an export license. Huang previously told investors that requirement effectively cut off Nvidia’s sales to China with “no grace period.” The AI chipmaker said that it would miss $8 billion in planned orders for the chip in the company’s July quarter.

“The $50 billion China market is effectively closed to U.S. industry,” Huang told investors on an earnings call in May.

Nvidia also faces another potential restriction on AI chip exports after the Trump administration cancelled a planned rule by former President Joe Biden called the “AI diffusion rule.” The Trump administration promised newer, simpler restrictions later this year on which countries could receive Nvidia’s technology.

Musk, X to face trial in Don Lemon lawsuit alleging breach of contract

Ex-CNN anchor Don Lemon‘s lawsuit against tech billionaire Elon Musk and his social network X over the cancellation of their partnership can proceed to trial, a San Francisco judge ruled this week.

Musk’s team had tried to get the case moved to a Texas court and tried to convince the judge to strike the complaint altogether.

Attorneys for Musk and X didn’t respond to a request for comment.

In an order Tuesday, Judge Harold Kahn said Lemon and his attorneys plausibly alleged, among other claims, that X and Musk had committed “fraud by false promise” and that there was “an implied contract” between them.

Lemon filed the suit in August 2024 after X canceled a partnership with the broadcast journalist a few hours after he taped a tense interview with Musk, who owns X. The interview preceded a planned premiere of Lemon’s new show on Musk’s social network.

During the interview, Lemon pressed Musk on several contentious topics he had posted about or amplified on X. Musk had boosted the so-called “great replacement theory,” and other bigoted tropes and falsehoods, including posts that claimed there was a “Hispanic invasion” of immigrants to the U.S.

Lemon also pressed Musk about content moderation on X, and a reported surge in antisemitic content on the platform that occurred after Musk acquired it as Twitter in a $44 billion leveraged buyout in late 2022.

Musk made sweeping changes after taking over the site, firing huge numbers of personnel and reversing account bans for users who had been booted from the platform after posting hate speech or inciting violence.

Musk, who characterized himself as a free speech “absolutist” also restored the account of President Donald Trump. The site had permanently banned Trump from the platform in January 2021 following the attack by his supporters on the U.S. Capitol.

Lemon’s case against Musk and X Corp. is in San Francisco Superior Court. A date has not been set for the trial.

Musk and X have faced a litany of other lawsuits over non-payment to vendors and over failure to provide severance as promised to laid-off employees from Twitter.

Lemon was fired from CNN in 2023 following reports that he mistreated coworkers and made sexist remarks on-air, including about politician Nikki Haley. Lemon later apologized for the Haley comments.

Bitcoin climbed to new all-time high on Thursday, building on its previous record reached just a day earlier, as investors jumped into risk assets and liquidated short positions.

The price of the flagship cryptocurrency was last higher by about 2% at $113,459.16. Earlier, it rose as high as $113,863.18.

On Thursday afternoon, bitcoin saw about $318 million in short liquidations across centralized exchanges in a 24 hour period, according to CoinGlass. When traders use leverage to short bitcoin and the cryptocurrency’s price rises, they buy bitcoin back from the market to close their positions, which pushes the price up and causes more positions to be liquidated.
