In recent years, scientists have raised alarms about the potential collapse of key ocean currents in the Atlantic, with ...

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

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.

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 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 ...

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

The amount of springtime sea ice in the Arctic set a record low this month, continuing a trend of shrinking ice at the top of the world.

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 ...

Arctic sea ice has declined significantly. Trends cannot be determined by looking at a short time frame over a few years.

Each September, the ice at the top of the world hits its lowest extent of the year. Researchers are studying how a warming climate is affecting a not-so-frozen ocean.

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 ...
