REUTERS/Dan Riedlhuber/File Photo Acquire Licensing RightsLONDON, Aug 22 (Reuters) - The fires that tore through the Canadian province of Quebec between May and July were made at least twice as likely by climate change, scientists said on Tuesday. Climate change, driven by the burning of fossil fuels, also made the fires as much as 50% more intense, according to the analysis by World Weather Attribution group, a global team of scientists that examines the role played by climate change in extreme weather. "Climate change is greatly increasing the flammability of the fuel available for wildfires – this means that a single spark, regardless of its source, can rapidly turn into a blazing inferno," said Yan Boulanger, a research scientist at Natural Resources Canada. Scientists reviewed weather data, including temperature, windspeed, humidity, and precipitation, and used computer models to assess how climate change had altered fire weather this year, comparing it to preindustrial climate. The Quebec fires are just one sliver of what has been the country's worst wildfire season on record.

Here are some questions and answers about Canada's wildfires, which have charred millions of hectares and polluted the air in that nation and the U.S.WHAT PARTS OF CANADA HAVE WILDFIRES HIT? Wildfires are common in Canada's western provinces, but this year the eastern provinces of Nova Scotia, Quebec and parts of Ontario have also reeled from out-of-control wildfires. This week, the focus returned to the west, as wildfires burned about 16 km (10 miles) northwest of Yellowknife, the capital of the vast, sparsely populated Northwest Territories. As of Wednesday, there were 1,054 active wildfires in Canada, including 230 in the Northwest Territories and 669 deemed out of control, according to the Canadian Interagency Forest Fire Center. Widespread spring fires across the whole of Canada are also unusual, and research shows fire seasons across North America are getting longer.

☆ Canadian wildfire emissions double previous record as flames rage on
▼ + stars: | 2023-08-03 | by ( ) www.reuters.com time to read: +3 min

The estimated Canadian fires emissions account for over 25% of the global total for 2023 to date, and are well above the previous Canadian record of 138 million tonnes registered in 2014, Copernicus said on Thursday. This year's wildfire season is also the worst on record for area burned, with about 131,000 square kilometres (50,579 square miles) already scorched across eastern and western Canada. Wildfire smoke is linked to higher rates of heart attacks, strokes, and more visits to emergency rooms for respiratory conditions. It's estimated that Canada's northern boreal forest stores more than 200 billion tonnes of carbon — equivalent to several decades worth of global carbon emissions. The carbon released is roughly equivalent to Indonesia's annual carbon dioxide emissions from the burning of fossil fuels.

CNN —An out-of-control blaze burning in northern Washington state exploded in size, crossed the Canadian border and set off a cascade of evacuations over the weekend. Evacuations were ordered on Saturday for more than 700 properties in the Canadian town of Osoyoos, British Columbia, after the fire crossed the border. The fire remains completely uncontained in both countries, according to Washington and Canadian fire officials. The United States’ fire season has been pacing below average in terms of acres burned so far this year. The US wildfire season may pick up pace as August arrives.

CNN —Smoke from more than 1,000 wildfires burning across Canada has wafted over the northern US, bringing poor air quality and pollution that threaten residents’ health to northern US cities including Chicago, Illinois, and Minneapolis, Minnesota. The bulk of the country’s wildfires are burning in British Columbia, where more than 460 fires are ongoing, the agency reports. The EPA in Illinois has declared an “Air Pollution Action Day” through Tuesday due to the “persistent” wildfire smoke causing elevated air pollution in the region. Wildfire smoke is packed with tiny pollutants – known as particulate matter – that can infiltrate the lungs and blood stream if inhaled. Hundreds of British Columbia’s fires have been ignited by lightning strikes from thunderstorms, according to the British Columbia Wildfire Service.

Fishing trips to Canada are a tradition for Jeffrey Hardy and his three friends from Vermont. They have, since 2001, been anglers loyal to Quebec’s northern wilderness, where the walleye are plentiful and the cellphone service is not. This summer, the crisp forest air coveted by recreationists visiting Canada was instead polluted with smoke as wildfires have torn through millions of acres, blocking roads, destroying campgrounds and forcing tourism operators to scramble during peak season. “Everybody was excited to go because Canada had been shut down for all of Covid.”The country’s worst wildfire season on record is straining the outdoor segments of Canada’s tourism industry at a crucial time in its rebound from years of pandemic travel restrictions. Of the 28.6 million acres that have burned across the country so far, more than 11.6 million acres were in Quebec, the most of any province, according to data from the Canadian Interagency Forest Fire Centre.

How Canada’s Record Wildfires Got So Bad, So FastWildfires in Canada have burned a staggering 25 million acres so far this year, an area roughly the size of Kentucky. With more than a month of peak fire season left to go, 2023 has already eclipsed Canada’s previous annual record from 1989, when over 18 million acres were scorched. Hot, dry conditions have fueled widespread wildfires, mostly in Canada’s boreal forests, since the spring, with some of the largest blazes burning in Northwest Canada and Quebec. A heat wave baked British Columbia and Alberta in mid-May, exacerbating several early wildfires. More than 100 times over the past three months, Canadian wildfires have grown sufficiently large and powerful to produce their own weather, kicking up giant thunderclouds known as pyrocumulonibus, and injecting smoke high into the atmosphere.

"This is the new reality, not the new normal, because we're on a downward spiral," Flannigan told CNBC. "The current wildfire season in Canada has been astounding and record breaking," Dahl told CNBC. "I'm not sure where we're going to end up with this because it keeps keeps on burning," Flannigan told CNBC. "The warmer it gets, the atmosphere gets more efficient at sucking the moisture out of the fuels," Flannigan told CNBC. For example, the mountain pine beetle is killing trees and turning them into fuel for wildfires, Burch told CNBC.

This year's wildfire season is the worst on record in Canada, with some 76,000 square kilometres (29,000 square miles) burning across eastern and western Canada. "The difference is eastern Canada fires driving this growth in the emissions more than just western Canada," said Copernicus senior scientist Mark Parrington. The carbon they have released is roughly equivalent to Indonesia's annual carbon dioxide emissions from the burning of fossil fuels. It's estimated that Canada's northern boreal forest stores more than 200 billion tonnes of carbon — equivalent to several decades worth of global carbon emissions. Canada's wildfire season typically peaks in late July or August, with emissions continuing to climb throughout the summer.

CNN —Canada has officially marked its worst wildfire season on record, with smoke from the blazes crossing the Atlantic Ocean and reaching western Europe on Monday. Canada has had a dramatic start to wildfire season, with at least 18,688,691 acres already charred across the country. Wildfire activity in Canada typically peaks from June to August, leaving more than half of the peak season still to come. As a result of the unprecedented start to the wildfire season, this year has become the worst fire season on record, surpassing the previous benchmark set in 1995 for the total area burned. The record wildfire season continues to impact air quality throughout parts of North America.

Footage of helicopters using flame-throwing torches to light fires has been misrepresented online, with social media posts claiming the clips show that the 2023 Canadian wildfires are being lit deliberately. This clip shows footage published on June 2, 2023 by the British Columbia (BC) Fire System (youtu.be/tTKSmdrfzqU?t=9), (youtu.be/tTKSmdrfzqU?t=15). According to the description of the video, it depicts a planned ignition on the Donnie Creek wildfire with a Heli-torch. There is also no evidence that aerial ignition caused the Canada wildfires, contrary to what these social media posts say. Footage shows planned fires ignited from helicopters, which are used to combat wildfires not deliberately light them.
