High severity burns bring higher concentrations of white ash and burned soil organic matter, which is more prone to erosion, overland flow, and leaching, while also being associated with low plant survival.

While climate change is the primary driver of permafrost degradation in Arctic Alaska, a new analysis of 70 years of data reveals that tundra fires are accelerating that decline, contributing disproportionately to a phenomenon known as "thermokarst," the abrupt collapse of ice-rich permafrost as a result of thawing.

By Saturday, the East Fork fire had grown to just over 108,000 acres but triggered no mandatory evacuations.

Drivers on the Coquihalla could feel the heat in their cars as they rushed to clear the highway before the July Mountain fire overtook it. Somewhere in the ashes is the route for the Trans Mountain pipeline, a project that would fuel the climate change that’s making these fires worse.

A pilot program in Alaska lets firefighters tackle fires deep in the wilderness that burn carbon and speed climate change and don’t just threaten homes and lives.

A deadly wildfire burned more than 2,000 buildings in the Hawaiian town of Lahaina on Maui in August and left behind piles of toxic debris.

As of Tuesday, the fire which prompted the evacuation of the city two weeks ago was still 15 kilometres west of Yellowknife. Fire officials declared the fire as "being held" on Monday.

A summer of devastating wildfires that burned huge swaths of the N.W.T. and forced countless communities across the country to evacuate has some experts questioning whether Canada is equipped for hotter, more intense fire seasons.

MOSCOW — Summer wildfires have already produced a record amount of carbon emissions in Russia’s Siberian region of Yakutia, with still more weeks of the fire season to come, according to the European Union’s Copernicus satellite monitoring unit.
