Large changes in global sea level, fueled by fluctuations in ice sheet growth and decay, occurred throughout the last ice age, rather than just toward the end of that period, a study published in the ...

The Hidden Danger Beneath Melting Antarctic Ice: At the end of the last Ice Age, something dramatic unfolded off the coast of Antarctica. As sea ice melted back toward the continent, it was like ...

When the planet was heating up at the end of the last Ice Age, ice-melt flooded out by glaciers made oceans rise. Scientists for decades believed that most meltwater had originated from Antarctica.

With the Arctic sea ice maintaining its trend of declining, average extent since the 1980s, there is another side to the story with a unique, slightly more positive statistic. The Arctic sea ice ...

CORVALLIS, Ore. — Large changes in global sea level, fueled by fluctuations in ice sheet growth and decay, occurred throughout the last ice age, rather than just toward the end of that period, a study ...

Sea ice coverage in the Arctic Ocean is at one of its lowest levels on record, yet there's no unanimity on when that ice will disappear completely during summer months. Understanding the traits and ...

Melting Arctic ice is revealing a hidden world of nitrogen-fixing bacteria beneath the surface. These microbes, not the usual cyanobacteria, enrich the ocean with nitrogen, fueling algae growth that ...

The Arctic Ocean, once locked in a vault of thick, old ice, now is transforming at lightspeed. Temperatures there are increasing at up to four times the rate of the planet overall, melting sea ice ...

Three Arctic seal species have been moved up to higher threat categories on the IUCN Red List, with one now endangered and two now near threatened. Global warming is melting away the sea ice they need ...
