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

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.

This is the story of 'Misha', as I have come to know her. Both I and my research have been deeply affected by a polar bear I have never met face to face.

Glacier mice aren't rodents – they're mysterious balls of moss that manage to live in one of the world's harshest environments.

The ice shelves surrounding the Antarctic coastline retreated at speeds of up to 50 metres per day at the end of the last Ice Age, far more rapid than the satellite-derived retreat rates observed today, new research has found.

"Two-cub litters—usually the norm for a healthy adult female—are likely to disappear in Baffin Bay in the next few decades if sea ice loss continues."

Newly available archival film has revealed the eastern ice shelf of Thwaites Glacier in Antarctica is melting faster than previous estimates, suggesting the shelf may collapse sooner than expected.

An international team of scientists has found part of the world’s largest ice shelf is melting 10 times faster than the overall ice shelf average due to solar heating of the surrounding ocean surface.
