Sea ice algae could shed light on past and future climate

Researchers have found a molecule in algae follows the ebbs and flows of sea ice. That could let them reconstruct past ice to shed light on climate change.

200 years ago, people discovered Antarctica – and promptly began profiting by slaughtering some of its animals to near extinction

For 200 years, a small number of countries have exploited the marine wildlife of Antarctica, often with devastating impact on their populations.

Where’s the sea ice? 3 reasons the Arctic freeze is unseasonably late and why it matters

The pattern of autumn sea ice growth has been completely disrupted, but are we really headed for a tipping point?

Arctic Ocean: why winter sea ice has stalled, and what it means for the rest of the world

The Laptev Sea is one of the Arctic's biggest nurseries of new sea ice in winter, but Siberia's record summer heat may have halted production.

The Arctic hasn't been this warm for 3 million years – and that foreshadows big changes for the rest of the planet

Extreme shrinkage of summer sea ice is just the latest evidence of rapid Arctic warming – and what happens in the Arctic doesn't stay there.

Thinner sea ice benefits some polar bears, but for how long?

Shrinking sea ice appears to improve the health of a small group of polar bears living above the Arctic Circle. But those benefits probably won't last.

Arctic sea ice is melting faster than anyone thought

Arctic sea ice is melting a lot faster than earlier estimates, which predicted a slow and stable rise in Arctic temperatures, researchers say.

Siberia heatwave: why the Arctic is warming so much faster than the rest of the world

Models have predicted for some time that with every degree of global warming, the Arctic will see double or more.
