How years of fighting every wildfire helped fuel the Western megafires of today

More than 40 fire scientists and forest ecologists in the US and Canada teamed up to investigate why wildfires are getting more extreme. Climate change is part of the problem, but there’s more.

We can’t predict the next wildfire disaster – but we can plan for it

Efforts to predict wildfire risk and to prioritize mitigation efforts aren’t enough. We must prepare for fire disasters wherever possible and decide what we’ll do when they happen.

Skip the fireworks this record-dry 4th of July, over 150 wildfire scientists urge the US West

Every year, the number of wildfires caused by humans spikes on Independence Day. There are safer ways to celebrate amid the heat and drought.

Trees are dying of thirst in the Western drought – here’s what’s going on inside their veins

Without enough water, trees can develop embolisms, similar to blockages in human blood vessels, and they’re more likely to die from drought or fires.

‘Managed retreat’ done right can reinvent cities so they’re better for everyone – and avoid harm from flooding, heat and fires

Managed retreat doesn’t always mean leaving. It’s about preserving the essential while redesigning communities to be better for everyone. Here’s what that can look like.

Rocky Mountain forests burning more now than any time in the past 2,000 years

Scientists studied charcoal layers in the sediment of lake beds across the Rockies to track fires over time. They found increasing fire activity as the climate warmed.

Bringing tech innovation to wildfires: 4 recommendations for smarter firefighting as megafires menace the US

Satellites can already spot a new fire within minutes, but the information they beam back to Earth isn’t getting to everyone who needs it or used as well as it could be.

Hurricanes, wildfires, tornadoes, floods – whatever your local risk, here’s how to be more weather-ready

Federal weather scientists are pushing to make the US more ‘weather-ready,’ which could mean prepping for fires, flooding or storms depending on where you live. The common factor: thinking ahead.

Prepare for the worst: 10 steps to get ready for wildfire smoke

Wildfire smoke is both inevitable and largely unpredictable. We need to change our activities and behaviours to limit exposure to wildfire smoke and protect health.

Western fires are burning higher in the mountains at unprecedented rates – it’s a clear sign of climate change

As the risk of fires rises in areas once considered too wet to burn, it creates hazards for mountain communities and for downstream water supplies.

How wildfires affect climate change — and vice versa

Recent wildfire seasons have been worsened by climate change. But wildfires also lead to additional climate warming when they release carbon dioxide to the atmosphere.

Another dangerous fire season is looming in the Western U.S., and the drought-stricken region is headed for a water crisis

Drought conditions are so bad, fish hatcheries are trucking their salmon to the ocean and ranchers are worried about having enough water for their livestock.

As extreme fires transform Alaska’s boreal forest, deciduous trees put a brake on carbon loss and how fast the forest burns

A new study finds more deciduous trees like aspen are growing in after severe fires in the region, and that has some unexpected impacts.
