Sea ice is a fundamental regulator of Earth’s climate and an increasingly urgent forecast target itself. Can we trust the AI systems now being built to predict it?

Wildfires Burned in Antarctica 90 Million Years Ago
A new study finds evidence for the southernmost wildfires currently known, which may have facilitated a transition from temperate rainforest to peatland in Antarctica.
We’ve Lost 11 Trillion Metric Tons of Ice Since the 1980s
Researchers have calculated that Greenland and Antarctica have lost 11 trillion metric tons of ice since the 1970s, which has led to a global rise in sea level of more than 3 centimeters.
Antarctica Is Releasing Mercury Faster Than Ever Because of Climate Change
A new study shows melting glaciers are remobilizing pollutants.
Tracking Penguin Poop from Space Reveals Antarctica’s Changing Ecosystems
Long-term records documenting the colors of penguin guano shed light on how declining sea ice may be affecting penguin diets.
The Breakup of Gondwana Over 100 Million Years Ago May Be Why Antarctica Has Ice Today
A rift event set off a domino effect of geologic processes that created conditions ripe for Antarctica’s glaciation, a new study suggests.
Rivers in the Antarctic Sky, Captured in 3D
A new study shows that atmospheric rivers may be responsible for up to 90% of Antarctica’s annual precipitation.
Sea Level Rise is Accelerating, Scientists Confirm
New research closes the sea level budget gap and takes account of the drivers of sea level change.
Changes in Sea Ice Microstructure Could Affect Climate Models
Granular sea ice needs to be twice as porous as columnar ice to allow water to flow through it—up to 10% brine by volume.
New Directions in Mapping Ice Sheet Fabrics and Flow
Polarimetric radar advances enable scientists to measure orientations of crystals, bubbles, and other properties that affect the flow of glaciers and ice sheets—and their contributions to sea level.
