Understanding sea ice loss requires expensive and difficult expeditions. Scientists have developed a new model that predicts the growth of small ponds on sea ice more efficiently.

The long tusk of the male narwhal earned these whales their fanciful nickname. But there’s more to these Arctic mammals than their unique spiral tooth.

Emperor Penguins thrive in harsh conditions, but a new study shows that their fate depends on human action to slow global warming and associated loss of sea ice.
Land clearing, cattle populations and carbon emissions stand alongside temperature as important measures of climate change.

What if the nightly news had regular updates on forest clearing, ocean temperatures and fossil fuel consumption? These indicators sit alongside temperatures as signs of climate change.

More than 600 experts will spend the next year drifting in Arctic waters to gain a better understanding of how climate change is affecting the region and how it can be fought.

Polar bears ‘invading’ a Russian village have renewed concern over climate change in the Arctic, but human-wildlife conflicts are flaring up everywhere.

An atmospheric scientist explains why water can do some strange-looking things at very cold temperatures, and what’s different about snowfalls on Mars.
Sea ice responds to changes in winds and ocean currents, sometimes with origins thousands of kilometres away.

Antarctic sea ice cover fell to an all-time low recently and hasn’t yet recovered. Why? The initial answers could lie in an unlikely place – the tropics.

Climate change is shrinking Arctic sea ice and opening the region to ship traffic. Whales, seals and other marine mammals could be at risk unless nations adopt rules to protect them.
Since 1995, several ice shelves off the Antarctic Peninsula have abruptly disintegrated. A new analysis suggests that these events are triggered when ice shelves lose their buffer of floating ice.

Last summer one of Antarctica’s floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.

A new study shows that polar bears require more food than previously thought. The scientists used collars that tracked bears’ movements and metabolic rates.
