Intense Heat, Drought Have Wildfires Raging from Brazil to Arctic Regions

This story includes details on the impacts of climate change that may be difficult for some readers. If you are feeling overwhelmed by this crisis situation here is a list of resources on how to cope with fears and feelings about the scope and pace of the climate crisis.

Across large swathes of California, Brazil, and the northern regions of Canada and Russia, wildfires are raging, incubated by intense heat and engrained drought.

The blazes are endangering all things in their immediate path and adding ever more atmospheric fuel to drive global heating.

In the latest news, the Washington Post reports a new fire has broken out in California, even as the rampaging Thompson blaze, which led to the evacuation of nearly 30,000 people last week, was reported contained. The latter happened thanks to the efforts of more than 1,400 fire personnel who had to contend with strong, gusting winds, and daytime temperatures in excess of 40°C.

Tropical Wetland On Fire

Meanwhile, wildfires continue to ravage Brazil’s Pantanal, one of world’s largest tropical wetlands, located south of the Amazon.

“Home to millions of caimans, parrots, giant otters, and the world’s highest density of jaguars,” the Pantanal has seen 3,538 wildfires break out since 2024 began, “an increase of more than 2,000% as compared with last year,” reports France24. “In June alone, 2,639 fires were detected—six times the highest number ever recorded.”

The rash of fires in the Pantanal is a tragic subset of a larger pattern unfolding across the Brazilian Amazon. According to latest data from Brazil’s National Institute for Space Research (INPE), the region “recorded 13,489 wildfires in the first half of the year, the worst figure in 20 years.” Experts say the spike in fires—“up more than 61% compared to the same period last year,” notes France24—owes to the historic drought the Amazon has faced since last year.

“The environment is drier, and thus vegetation is more dried out and more vulnerable to fires,” Brazil Greenpeace spokesperson Romulo Batista told France 24. He added that the majority of the current fires were likely caused by agricultural burning, not wildcard factors like lightning strikes

The latest INPE data is grim news for Brazil’s government, “with the number of fires increasing even as deforestation in the Amazon—which helps reduce global warming by absorbing carbon dioxide—is on the wane,” the news story states. Forest loss has “decreased 42% from January 1 to June 21, as compared with the same period in 2023.”

But the rainforest is not the only part of Brazil that is burning. Spanning a territory equal to France, Germany, Italy, Spain and the UK combined, the Cerrado, “one of Earth’s three great savannas, along with Africa’s and Australia’s, experienced 13,229 fires from January through June, almost as many as the Amazon.”

Arctic Aflame

Wildfires are also raging across the northern reaches of the planet, from Fort Nelson, British Columbia to Russia’s Sakha Republic.

The Patry Fire, currently burning some 22 kilometres from Fort Nelson (pop. 3,400), first ignited last July, slumbering through the winter as a so-called “zombie fire”. Now fully awake, reports CTV, it is currently more than 700 kilometres square and growing, after switching virtually overnight from being designated “held” to “out of control”.

The Arctic Ocean-bordering Sakha Republic is likewise ablaze in Russia’s far east corner, with the three-million-square-kilometre region accounting for 72 of the 164 wildfires recorded in the Arctic Circle through June 24, states a release from the European Union’s Copernicus Atmosphere Monitoring Service (CAMS).

The vast swathes of northern boreal forest and tundra now ablaze bode very ill for the global climate. The latest data collection effort by CAMS showed carbon emissions over the Arctic region t the third-highest level for June since 2003.

The connection between wildfires and carbon emissions is confirmed by a new analysis of the atmospheric impact of Canada’s 2023 wildfires conducted by researchers from the World Resource Institute’s (WRI) Global Forest Watch Initiative and the University of Maryland. Roughly 7.8 million hectares of forests burned in Canada last year, “more than six times the annual average since 2001,” the research team writes in the journal Global Change Biology.

Those fires produced “roughly three billion tons of carbon dioxide—nearly four times the carbon emissions of the global aviation sector in 2022, and 25% more than from all tropical primary forest loss combined in 2023.”

CAMS also warns of the potential for a dangerous feedback loop if the Arctic fires lead to extensive deposition of black carbon and soot. Such deposition “can potentially darken snow and ice surfaces, reducing their albedo and causing them to absorb more solar energy, making them more prone to melting,” the agency states.
