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

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

Even during the coldest 750,000 years, the Arctic Ocean had open water and sustained life thanks to seasonal sea ice. “Our ...

Today’s Arctic sea ice is more likely to resemble a snow-covered parking lot than the chaotic ice blocks Nansen saw. Two years of tanking summer sea ice—in 2005 and 2007—exposed the dark ...

New research by an international team of scientists explains what's behind a stalled trend in Arctic Ocean sea ice loss since 2007. The findings indicate that stronger declines in sea ice will ...

Seasonal sea ice forms and melts every year creating openings in the ice with open water where life can continue to thrive.

The Arctic could be free of sea ice roughly a decade earlier than projected, scientists warn – another clear sign the climate crisis is happening faster than expected as the world continues to ...

This past summer in the Arctic was the warmest since 1900, leading to early snowmelt and diminished sea ice. ... in both the ocean and freshwater ecosystems central to the salmon life-cycle. ...

Should the Arctic ice continue to melt, sea levels will rise. Higher temperatures in the Arctic could affect weather in parts of North America, Europe and Asia with extreme rainfall and heat waves.

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.

Sea-ice coverage in the Arctic shrinks in spring and summer and reaches a minimum in mid-September. This year, it’s on track to be the sixth lowest on record. The record was set in 2012, and ...

Winter sea ice in the Arctic just hit a record low Just 5.53 million square miles of ice had formed as of March 22, the smallest maximum extent since satellite recordkeeping began in the 1970s ...
