For the first time, scientists have mapped in detail water locked in a deep basin far under the Antarctic ice. The discovery could have implications for how the continent reacts to, or even contributes to, climate change.

Sea ice in the Southern Ocean retreats each year much faster than it develops. This has puzzled scientists, but the explanation turns out to be simple.

Using radar and other techniques, researchers have mapped out the sediments left by a lake that apparently existed before Greenland was glaciated. Next step: drilling through the ice to see what they contain.

To measure algal blooms across large regions of the Greenland ice, and understand their effects on melting over time, scientists are turning to space.

The warmer it gets, the faster Antarctica will lose ice, and at some point the losses will become irreversible. That is what researchers say in a new cover story in the leading journal Nature, in which they calculate how much warming the Antarctic Ice Sheet can survive.

Using satellite images spanning decades, a new study has found that the northern tundra is becoming greener, as warmer air and soil temperatures lead to increased plant growth.

Newly discovered seabed channels beneath the Thwaites Glacier may be pathways for warm ocean water to melt the ice’s undersides and contribute to sea level rise.

A new study says that many of the ice shelves ringing Antarctica could be vulnerable to quick destruction if rising temperatures drive melt water into the numerous fractures that currently penetrate their surfaces.

An international team of polar researchers says that the Greenland ice sheet experienced record loss in 2019.

In a new book, glaciologist Marco Tedesco takes the reader on a personal journey through his sometimes dangerous work.
