Stability Check on Antarctica Reveals High Risk for Long-Term Sea Level Rise
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.

Warmer Temperatures Drive Arctic Greening
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.

Ancient Volcanoes Once Boosted Ocean Carbon, But Humans Are Now Far Outpacing Them
A new study of the closest ancient analog to modern carbon emissions finds that massive volcanism was the main cause of high carbon at the time. But nature did not come close to matching what humans are doing today.

Deep Channels Linking Antarctic Glacier’s Underside to Ocean Could Hasten Melting
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.

Antarctic Ice Shelves Vulnerable to Sudden Meltwater-Driven Fracturing, Says Study
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.

A Look at Climate-Caused Harms Unfolding in Peru’s Cordillera Blanca
Focusing on ice loss, glacier hazards, and water variability due to climate change, a new study highlights challenges for communities in Peru’s mountain cryosphere systems.

Greenland Ice Sheet Saw Record Loss in 2019
An international team of polar researchers says that the Greenland ice sheet experienced record loss in 2019.

Fossil Leaves Show High Atmospheric Carbon Spurred Ancient ‘Global Greening’
Scientists studying leaves from a forest that stood during a warm period 23 million years ago have for the first time linked high levels of atmospheric carbon dioxide with increased plant growth, as well with the high temperatures of the time.
