Cranking up the heat on a world already on fire

This story is part of the World on Fire series, a podcast that takes us to the front lines of out-of-control wildfires in Canada, Australia and California.Recorded during the COVID-19 pandemic, each episodeexamineswhat it takes to find hope in the midst of fear and destruction. Wildfires cost us our health, our homes and our communities, yet people everywhere rebuild and not just survive but thrive.

Diondray Wiley and his crew are surrounded by things that could kill them.

"We're seeing extreme fire behaviour on every fire, so I don't know if it's extreme anymore," saidWiley, training chief with the Santa Barbara County Fire Department in Southern California.

Fuels are drier, winds are wilder, lakes are lower and the firefighters working in Plumas National Forest, part of the BeckwourthComplex Fire, are facing it all at about 40 C, some eight degrees above what's normal for this time of year.

"Extreme is kind offatiguing," Wiley said. "People hear that so much and what we're witnessing is so unrealistic but it's what we do now."

Wiley, who is also a fire behaviour analyst with the U.S.Forest Service, says the season has started nearlytwo months before it normally does in this region. It is alreadystretching crews thin.

Now in his 27th season, Wiley is up at 4 a.m. reviewing weather data and planning theattack. He's still up at 11:30 p.m., mapping out the strategy for the next day.

"I'm trying to look, instead of at my toes, look at the horizon," he saidin what he knows is going to be a long, hot season.

Fingerprint of climate change

"It's just been astonishing," saidJohanna Wagstaffe, ameteorologist, seismologist and science reporter at CBC Vancouver who has been consulting with colleagues across the continent.

"We've never seen anything like this."

She says theterm "record-breaking" doesn't really capture the effects of the heat-dome pressure cooker that Western Canada was recently under.

In early July, the BCCoroners Service reported 719 sudden deaths in one week, triple the number that would normally occur in the province in a seven-day period.

"The fingerprint of climate change is all over this," Wagstaffe said.

Scientists are still taking stock of the effects on plants and animals, but one example is that"the leaves have fallen all over metro Vancouver," saidWagstaffe. The stress has shocked sometrees into shutting down.

Jeff Kavanaughsays temperatures we have experienced from late June to early July amount to a one-in-1,000-year heat wave.

And he isn't so sure another one won't come around sooner.

Government inaction 'terrifying'

An associate professor of atmospheric sciences at University of Alberta, Kavanaugh clocked the melting of Alberta glaciersat about three times faster than average.

An accelerated melt is bad news for thewater supply, especially in the summer when other sources of precipitation, like rain, have beenhard to come by.

Kavanaugh says there are credible predictions that most of the ice will disappear in Western Canada by 2100.

"Individuals can only do so much. Governments and corporations need to do more to try to mitigate this. To not see that happen year in and year out, is really quite terrifying."
