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.
It's comforting to blame California's wildfires on human stupidity. But this hides a very uncomfortable truth.
The high temperatures and wildfires of 2019 were thought to have heralded a freak summer for the Arctic. Then 2020 brought worse.
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.
Drones have proven extremely useful for research, collecting detailed data to help monitor hard-to-access areas.
Not only can plants survive fire, they can use the experience of being burned to prepare themselves for future blazes.
The boreal forest is being reshaped by wildfire. As climate change intensifies wildfire activity, the boreal forest will likely become a carbon source.
Yes, there are more fires in Africa than Brazil. But unlike the Amazon, Africa's savannah has evolved to grow back quickly.
