An asteroid may have exploded over Antarctica about 2.5 million years ago
Tiny spherules of rock found in Antarctic ice may point to the oldest known “airburst,” or midair disintegration of an incoming asteroid.

Earth’s inner core may be changing shape
Earthquake data suggest that all or small patches of the inner core's surface may be swelling and contracting.

3 Antarctic glaciers show rapidly accelerated ice loss from ocean warming
Destabilized by ocean waves and vanishing sea ice, Antarctica’s Hektoria glacier lost 25 kilometers of ice in 16 months — a possible hint of what’s to come.

Climate change made 2024 the hottest year on record. The heat was deadly
Heat waves fueled by climate change killed scores of people and upended daily life. Here are some of those stories.

Warm water is sneaking underneath the Thwaites Glacier — and rapidly melting it
The salty water, just 3.6 degrees Celsius above the ice’s melting point, is undermining the foundation of the Antarctic glacier.

Emperor penguins lost thousands of chicks to melting ice last year
In 2022, groups of emperor penguins in western Antarctica lost almost all their chicks to receding sea ice, signaling the threat of climate change.

We may finally know the source of mysterious high-energy neutrinos
Regions around supermassive black holes in active galaxies could produce a lot of these mysterious particles.

Antarctic sea ice has been hitting record lows for most of this year
Since hitting a record low minimum back in February, the amount of Antarctic sea ice has stayed well below normal all year.

Climate change is driving the extreme heat baking France’s Olympics
In this week’s Extreme Climate Update, we look at record-breaking temps around the world and explain what the heat index is.

Something weird is happening to Earth’s inner core
A new study claims to confirm that the inner core is now rotating more slowly than it was over a decade ago, but some researchers remain skeptical.

Could Spinosaurus swim? The fierce dinosaur ignites debate
Researchers are still divided about whether Spinosaurus was a swimmer or a wader. What’s clear is that confirming the first swimming dinosaur would be a game-changer.

Climate change is changing how we keep time
Polar ice sheets are melting faster, slowing Earth’s spin. That is changing how we synchronize our clocks to tell time.
