Some projections say that by 2040 the Arctic Ocean may see its first ice-free summer in modern history. That means mixed emotions for young scientists seeing the ice for the first time.

The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. Researchers explored strategies for ...

A new study challenges the long-debated theory that a massive, kilometre-thick ice shelf once covered the entire Arctic Ocean. By analysing ocean sediments and running advanced climate models ...

A recent study shows ocean acidification is happening much faster in the Arctic than oceans elsewhere.

It’s hard to imagine the Arctic without sea ice. But according to a new study by UCLA climate scientists, human-caused climate change is on track to make the Arctic Ocean functionally ice-free for ...

A coalition of over 1,000 scientists has taken the occasion of this week’s U.N. Ocean Conference in Nice to call for a global agreement that would prevent industrial activities in the Central ...
