New research challenges the long-held belief that the Arctic Ocean was covered by a massive ice shelf during ice ages.

For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ...

The Arctic Ocean could see "ice-free" days within a matter of years—potentially a decade earlier than was previously predicted. This is the warning of a team of researchers from the University ...

Summer sea ice in the Arctic Ocean might be gone by the 2030s, no matter what we do to curb emissions of greenhouse gases, study says.

The first ice-free days of the Arctic Ocean could occur as soon as the 2020s or 2030s — as many as 10 years earlier than previous projections.

Arctic ice is getting thinner by the day—and sea life is suffering A new study says the structural change has been abrupt, making life harder for everything from tiny algae to polar bears.

The Arctic Ocean's ability to absorb carbon dioxide from the atmosphere appears to be waning due to melting permafrost and worsening coastal erosion.

A new study shows that the Arctic has warmed nearly four times faster than the rest of the world over the past 43 years. This means the Arctic is on average around 3℃ warmer than it was in 1980.

A recent study of Arctic Ocean waters showed rapid acidification and Cai and his collaborators have published their findings in the journal Science. Scientists have predicted that by 2050 — if not ...

In the Arctic Ocean, sea ice is shrinking as the climate heats up. In the Western U.S., wildfires are getting increasingly destructive. Those two phenomena are thousands of miles apart, but ...

Back in March a modified Ford F-150 fell through some ice near the Tasmania Islands at the Arctic Circle. The truck was part of a circumnavigation journey ...
