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 ...

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.

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

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.

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.

UD doctoral student Tianyu Zhou is pictured on the right using a shovel to remove snow that covers the sea ice during a research cruise to the Arctic Ocean in the fall of 2024. Within the square that ...

For decades, scientists believed the Arctic Ocean was sealed under a massive slab of ice during the coldest ice ages — but new research proves otherwise. Sediment samples from the seafloor, paired ...

Nearly all Arctic sea ice could melt by the summer of 2027, scientists warn For the first time, a group of international scientists used climate models to predict when the Arctic might see its ...

Acidification in the western Arctic Ocean is happening at a rate three to four times higher than in other ocean basins.

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 ...
