A decrease in pressure ridges over the past 3 decades is making the ice more uniform, with unclear consequences.

Scientists have quantified how much climate change has driven the population decline of polar bears living in Canada's Hudson ...

In order to estimate the direct effects of the observed changes on the Arctic ecosystem, models need to be developed that can reflect both physical and biological processes in sea ice of various ages.

The 'Last Ice Area' is expected to be the final place in the Arctic where ice persists all year round even as our planet warms up – but a new study suggests the region, and the ecosystem that relies ...

In order to estimate the direct effects of the observed changes on the Arctic ecosystem, models need to be developed that can reflect both physical and biological processes in sea ice of various ages.

Polar bears in Western Hudson Bay have seen their population nearly halved over the last several decades, largely due to dwindling sea ice and limited hunting opportunities, according to the findings ...

These ridges are created when ice floes press against each other and become stacked, and are a characteristic feature of Arctic sea ice, an obstacle for shipping, but also an essential component of ...
