Ancient ice age valleys offer clues to future ice sheet change

Deep valleys buried under the seafloor of the North Sea record how the ancient ice sheets that used to cover the UK and Europe...

Scientists expose vulnerabilities of critical Antarctic ice shelf

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to...

Record of Antarctic ice sheet response to climate cycles found in rock samples

By analyzing unusual rock samples collected years ago in Antarctica, scientists at the University of California, Santa Cruz, have discovered a remarkable record of...

For the first time, we can measure the thickness of Arctic sea ice all year round

Using satellites, we are now able to measure ice thickness in the Arctic—even in the summer. This is of great importance for shipping in...

A global vision for the ocean

A new scientific article published in Frontiers in Marine Science calls attention to the need for a global vision for the ocean in the...

Antarctica’s ice shelves could be melting faster than we thought

A new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually...

World’s biggest ice sheet could cause massive sea rise without action

The world's biggest ice sheet could cause "several meters" of sea-level rise over centuries if the global temperature rises more than 2°C, according to...

Swiss mountain pass ice to melt completely within weeks

The thick layer of ice that has covered a Swiss mountain pass for centuries will have melted away completely within a few weeks, a...

Ice core taken in Antarctica contains sample of atmosphere from five million years ago

A team of researchers affiliated with multiple institutions in the U.S. has successfully pulled an ice core from Antarctica's Ong Valley that contains samples...

Arctic warming four times faster than rest of Earth: study

The Arctic has warmed nearly four times faster than the rest of the planet over the last 40 years, according to research published Thursday...

Recent studies find previously unknown loss of Antarctic ice

New research on Antarctica, including the first map of iceberg calving, doubles the previous estimates of loss from ice shelves and details how the...

Scientists discover world’s longest underwater avalanche after rescue of lost data

Prompt action by scientists recovered sensors drifting across the Atlantic Ocean that held data on a seabed sediment avalanche that traveled for 1,100 km...
