Heat stress can turn deadly even sooner than experts thought
As temperatures rise, new research shows critical limits for how heat affects the body may be lower than previously thought. Humidity is a big factor.
Could some species dying on Earth be saved in outer space?
A process called cryopreservation allows cells to remain frozen but alive for hundreds of years. For some animal cells, the moon is the closest place that's cold enough.
Too hot for a lizard? Climate change quickens extinction
A disappearing lizard population in the mountains of Arizona shows how climate change is fast-tracking the rate of extinction.
Scientists trying to protect wildlife from extinction as climate raises risk
Scientists are using a range of tools to protect the endangered wildlife that could disappear in coming decades.
Endangered Puerto Rican parrot threatened by fiercer hurricanes
Hurricane Maria nearly wiped out an endangered parrot in Puerto Rico, highlighting the grave threat climate change-fueled storms pose to endangered species.
How one city is working to close the EV "charging gap"
The U.S. needs more than a million public chargers by 2030, but only a fraction of that number currently exists. Los Angeles is using light poles to help fill the gap.
Contrails from airplanes are warming the planet. Could AI offer a solution?
Feathery white lines of condensation left behind airplanes, known as contrails, add to warming the planet. A new study suggests artificial intelligence could dramatically reduce them.
Why scientists are hunting for the oldest ice in Antarctica
Their work near the South Pole means camping on the ice without showers or flushing toilets for seven weeks — but what we can learn about climate change there is essential to science.
More than 70 million face increased threat of sea level rise worldwide
New data finds the impact of climate change on coastal flooding could increase five-fold by the end of the century, leading to major property and infrastructure losses.
Climate solutions from the Arctic, the fastest-warming place on Earth
Climate change is an urgent problem in the Arctic. From renewable energy to avalanche protection, here's what we can learn from how people there are protecting their way of life.
Ancient methane escaping from melting glaciers could warm the planet more
Spiking temperatures in the Arctic are rapidly melting glaciers. Scientists are now worried about underground methane, a potent greenhouse gas, leaking up to the surface.
Air quality has been horrible this year — and not just due to wildfire smoke
Smoke from wildfires is not the only reason for poor air quality this year. It turns out, those wildfires created another kind of pollution: Ozone.
LED lights are erasing our view of the stars — and it's getting worse
The national push for more efficient lighting is driven by a quest for energy efficiency. But there's an unintended consequence: light pollution.
"Chasing arrows" plastic recycling symbol may get tossed in the trash
It's universally recognized as a sign to recycle. But the EPA is now saying it's also universally confusing, since many plastics can't easily be recycled.
How AI technology could be "a game changer" in fighting wildfires
As more people across the country are seeing the impact of wildfires and smoke, scientists are turning to the promise of big data, technology and collaboration to keep big fires from spreading.
