Ancient rocks reveal when rivers began pouring nutrients into the sea
Rivers began pumping weathered material into the sea about a billion years after Earth formed, suggesting continents may have gotten an early start.
- Climate
Yes, you can blame climate change for the LA wildfires
Weather data show how humankind’s burning of fossil fuels made the hot, dry, windy weather more likely, setting the stage for the Los Angeles wildfires.
- Earth
Ghostly white northern lights present new auroral mystery
These mysterious whitish-gray glows in the northern lights might be cousins of the mauve light streak known as STEVE.

Another danger looms after the LA fires: Devastating debris flows
As wildfires burn the landscape, they prime slopes for debris flows: powerful torrents of rock, mud and water that sweep downhill with deadly momentum.
- Climate
Unearthed ice may be the Arctic’s oldest buried glacier remnant
Thanks to climate change, thawing permafrost in the Canadian Arctic has revealed the buried remnant of a glacier that’s 770,000 years old.
- Environment
A podcast challenges us to reassess our relationship with wildfires
United by Fire lays out key insights from the two largest blazes in Colorado history, the Cameron Peak and East Troublesome fires of 2020.
- Climate
2024 was Earth’s hottest year on record, passing a dangerous warming threshold
Global temperatures were the hottest on record in 2024; it was the first year where the average temperature topped 1.5 degrees Celsius above preindustrial times.
- Paleontology
Humans, not climate change, may have wiped out Australia’s giant kangaroos
About 40,000 years ago, giant kangaroos vanished Down Under. Dental analyses suggest a varied diet, meaning climate change was not the main cause.
- Climate
California wildfire season should be over. So why is L.A. burning?
In some parts of California, fire season is now year-round due to rising heat and little rain. High winds and dry conditions are fueling L.A.’s infernos.
- Particle Physics
Cosmic rays could help reveal how tornadoes form
Subatomic particles called muons could measure pressure changes in supercell thunderstorms and the twisters they kick up.
- Animals
More new geckos have been found hiding in Southeast Asia’s limestone towers
Nearly 200 new gecko species found in living in karst landscapes reveal the rugged regions as dynamic areas of speciation.
- Animals
‘Forever chemicals’ are causing health problems in some wildlife
Deformed scales in hatchlings and biomarkers indicative of disease progression are two health impacts on turtles at PFAS-polluted sites in Australia.
