An increasing number of communities are discovering dangerous contamination in their water systems weeks or months after fires.
As bushfires become larger under climate change, the area exposed to intense and severe fires is likely to increase.
Governments can align their policies to tackle both climate change and post-pandemic recovery.
Removing trees killed by fires can have long-term consequences for wildlife.
To understand the risks of wildfire smoke, it helps to understand the chemicals people are breathing.
Deforestation and extreme blazes threaten the region's biodiversity, risk transforming the rainforest into a semi-arid savannah and expose people to zoonoses that could spur new pandemics.
Debating whether climate change or forest management has caused the devastating wildfires in California, Washington and Oregon is a false choice.
Coping with intense and prolonged wildfire smoke is difficult, both physically and mentally. Smoke is an environment hazard to be respected, not a personal challenge to be overcome.

Persistent heat waves and dry lightning are part of the problem. For firefighters, the erratic behavior gets dangerous quickly.
Arctic heat waves were once rare and unusual events. But as their intensity and frequency increase with climate change, their fallout could affect the north — and the planet — for decades to come.
Last summer, Australia's wildlife burned in one of our country's worst bushfires. So what's become of animal and plant survivors in the months since?
The US faces a high risk of hurricanes and other disasters this year that could leave thousands of people in need of shelter. COVID-19 will make those disasters more dangerous to manage.
Unstable funding, social distancing and the likelihood that other countries won't be able to help — these all raise the potential of a nightmarish scenario.
The pandemic has exposed how vulnerable we are to unexpected climate shocks.
Wildfire smoke makes it harder for firefighters' bodies to fight off viral invaders. But firefighting conditions make the usual protective measures nearly impossible.
The water that replenishes groundwater, rivers and lakes is under threat from climate change, pollution and aging infrastructure.
Real Christmas trees may be in short supply this year thanks to the 2008 economic downturn, climate change and insect infestations.
Emergency responders and military personnel need to think creatively – even imaginatively – to save lives under pressure. Analyzing the Grenfell Tower Fire in London reveals useful lessons.
