Climate Change

The news about climate change is compiled in the Polar Current. This news include worldwide news on climate change, the Greenland and Antarctic ice sheets, and sea level rise. To follow these global trends, check back weekly or click the orange icon below for a subscription to the feed.

Two key climate change indicators -- global surface temperatures and Arctic sea ice extent -- have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite data.
Two separate groups of scientists have studied the West Antarctica ice sheet and submitted their findings Monday. According to their research, the ice sheet is falling apart and this poses a problem. Melting ice sheets cause oceans to rise and findings suggest the melting from both Antarctica and...
Ice sheets are slowly thawing as water eats away at their core, eroding them where they graze the oceans. Slowly thawing ice is pouring water into the sea, at 130 billions tons of ice per year for the past decade, NASA satellite calculations reveal. This is enough to fill more than 1.3 million...
Ever since its discovery was announced earlier this year, the 3 km-wide ring structure discovered on the of Antarctica has been a source of significant interest and speculation. Initially, the discovery was seen as little more than a happy accident that occurred during a survey of East Antarctica...

In addition to adding water to the oceans, eroding ice sheets are also contributing significant amounts of carbon that feed the bottom of the food chain in marine ecosystems. "This is the first attempt to figure out how much organic carbon is in those glaciers and how much will be released when...
The best look yet at the hidden, ice-covered volcanic mountains in West Antarctica's Marie Byrd Land reveals never-before-seen deep valleys and steep, glacier-carved ranges, a new study reports. The findings, from a radar survey that can "see" through snow and ice, could force researchers to redraw...
Biological field stations at the University of Kansas and Kansas State University soon will be part of one of the most extensive long-term initiatives in the history of the National Science Foundation. The NSF-funded National Ecological Observatory Network, or NEON, will gather data on the causes...
Scientists using robotic ocean gliders to wander frigid Antarctic waters say they may have discovered a mechanism behind the melting of polar ice shelves – miniature submarine "storms" that are lobbing packets of warmer water toward the continent. The findings, published in the journal Nature...

A new core from West Antarctica, drilled to a depth of 3,405 meters in 2011 and spanning the last 68,000 years, has “extraordinary detail,” said Oregon State paleoclimatologist Edward Brook, a co-author on the Nature study and an internationally recognized ice core expert. Because the area where...
The Antarctic ice is host to very little life, yet often researchers find that beneath the frozen surface we find remnants and a record of our past. Core ice samples not only reveal atmospheric concentrations of particular molecules in ancient skies, giving us a view of how the Earth's climate has...
The risk of severe winters in Europe and northern Asia has been doubled by global warming, according to new research. The counter-intuitive finding is the result of climate change melting the Arctic ice cap and causing new wind patterns that push freezing air and snow southwards. The new work is...
October 21 A large and prestigious National Science Foundation (NSF) research program in Antarctica has uncovered important scientific discoveries about climate change, the origins of the universe, previously unknown sea life and two new dinosaur species. Leading this ambitious effort is Scott...
Although not designed to map changes in Earth’s gravity over time, ESA’s extraordinary satellite has shown that the ice lost from West Antarctica over the last few years has left its signature. By combining GOCE’s high-resolution measurements with information from Grace, scientists can now look at...
