Very little is known about rainfall in Antarctica; precipitation falls as snow on the bitter cold ice-covered continent. But during the austral summer of 2013-2014, an Adélie penguin colony near Dumont d’Urville station on coastal Adélie Land experienced “unusual and dramatic rainfall event that occurred on January 1, 2014, and that was...

“We might (and I stress might) have already reached and passed a point where there is really no turning back for Thwaites, no matter what we as humans do to our climate,” Alastair Graham, the University of South Florida and co-author of the study. New data from under the ice stream...
It is no surprise to those who follow the deglaciation process in Antarctica and are aware of the real threat posed by these glacial behemoths to human civilization. Rapid sea-level rise is likely when Pine Island and Thwaites (A/K/A The Doomsday glacier) glaciers collapse and take all of West Antarctica with them....
The most menacing glacier for coastal regions worldwide is the Thwaites glacier, aka the doomsday glacier, located in the active climate tipping point region of West Antarctica. Recently a new study found that Thwaites glacier’s marine extension’s underbelly is melting on all sides by warming ocean water. Researchers found that...
Pine Island Glacier is located in West Antarctica, has shed yet another major iceberg. The calving event is not unusual for this glacier. What is new is change over the years is that calving events have changed from a multi-year process to an annual process. The bergs from Pine Island...
Leading scientists have warned that nine of the tipping points identified over a decade ago are now active. One of those tipping points is the West Antarctic Ice Sheet (WAIS). Thwaites glacier, also known as the doomsday glacier, has been alarming scientists about a looming collapse that could raise sea...
Indonesia is one of the most vulnerable nations on earth to climate change. Indonesians will face more intense floods, droughts and sea level rise in the years to come. The low lying and densely populated nation has 18,000 miles of coastline and many islands at sea level. Winds and rainfall...
And what seems clear now is that Greenland is no longer changing in geological time. It is changing in human time. Jon Gertner, Yale Environment 360 ...
Three new studies raise the specter that the great ice platforms of the Antarctic continent are more unstable and susceptible to collapse than previously thought. Antarctica holds ninety percent of the world’s store of freshwater and would raise sea levels 230 feet if it all melts. East Antarctica’s ice is...
“We have never observed an ice sheet behaving this way before. It’s unprecedented in human scientific history.” – Kristin Poinar, Glaciologist, University of Buffalo Greenland is, for the most part, a very moist environment (with the exception of northern Greenland which until recently had been a dry environment). The ice...
I keep vigil. Lots of activity on the world's largest reserve of fresh water. x Following the startling narrative of the IPCC report on the Oceans and Cryosphere, our open access paper came out yesterday in Nature Scientific Reports documenting >65,000 lakes on the surface of the East Antarctic Ice...
