For decades, the sea ice around Antarctica expanded every winter, only to shrink rapidly in 2015. Now, a study reveals what has caused this drastic change. Elephant seals have helped with the measurements.
A new study shows that there is a link between rising temperatures and changes in polar bears' DNA. This may help the bears adapt to increasingly challenging environments.
Spring is coming, even to the North Pole. But winter is summarised by alarm bells - never before has ice cover peaked at such a low level as this season, according to the Danish weather agency DMI.
Sea ice at the poles, which helps cool the Earth, is at its lowest levels recorded this time of year, according to new satellite measurements, reports the BBC.
The sea ice in the Arctic will melt much faster than previously thought because today's climate models underestimate the rate, according to new research.
Follow along as filmmakers Johan Candert and Simon Stanford embark on their first tentative journey far out on the sea ice. There they will try to film "The Secret Life of the Seal", but it was not as easy as they first thought
