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.

Utilizing ice-penetrating radar to study Greenland, scientists have found fragmented, skyscraper-size blocks of ice at the bottom of the ice sheet, seemingly developed as water beneath the ice refreezes and distorts the surrounding ice upwards. The amazing ice structures may help researchers learn...
A team of scientists, funded by the National Science Foundation (NSF), has successfully used a new technique to confirm the age of a 120,000-year-old sample of Antarctic ice. The new dating system is expected to allow scientists to identify ice that is much older, thereby reconstructing climate...
Over the winter, as polar vortices plunged the U.S. Midwest into weeks of unceasing cold, the icy covers of the Great Lakes started to make headlines. With almost 96 percent of Lake Superior's 32,000 miles encased in ice at the season's peak, tens of thousands of tourists flocked to the ice caves...
It’s that time of year again: No, we’re not talking allergies flaring or cherry blossoms blooming, but the Arctic ice cap reaching its maximum size for the year. Arctic sea ice reached its maximum area, or extent, on March 21, after a brief late season surge in ice formation. The total amount of...
YOKOHAMA, Japan — Climate change is already having sweeping effects on every continent and throughout the world’s oceans, scientists reported on Monday, and they warned that the problem was likely to grow substantially worse unless greenhouse emissions are brought under control. The report by the...
The impacts of climate change are being felt at even the deepest depths of the Antarctic ocean, a new study has found, in a discovery that may explain a 40 year old mystery. In the mid-1970s, the first satellite images to be studied of Antarctica during the polar winter discovered a strange...
Academics at Aberystwyth University have been awarded £340,000 to research into the processes that drive the fast flow of these glaciers because a growing body of evidence points to a strong response to both oceanographic and atmospheric forcing.
During a routine test of an underwater robot, NSF scientists from University of Nebraska-Lincoln made a startling discovery - an entirely new species of sea anemone living inside the ice.
A massive ancient subglacial trough -- deeper than the Grand Canyon -- has been discovered by a team of UK experts. They charted the Ellsworth Subglacial Highlands -- an ancient mountain range buried beneath several kilometres of Antarctic ice -- by combining data from satellites and ice-...
One of the latest indicators that climate change is progressing whether we’re looking or not comes from a study in the journal Nature Climate Change finding that one of the largest glaciers in Antarctica has started melting irreversibly. An international team of researchers found that Antarctica’s...
As it does most years, CReSIS has sent out multiple teams to the Arctic and Antarctic regions to collect data on ice formations that will hopefully lead to more and more precise models of what the world's glaciers will do to sea levels as climate change continues and ramps up. The Operation Ice...
While the rest of the world hunkers down inside during winter and fantasizes about warmer climates, scientists at Kansas University's Center for Remote Sensing of Ice Sheets, or CReSIS, head off to some of the coldest places on Earth. This winter again saw teams from CReSIS, a multi-university,...
The Australian mercy mission icebreaker is being thwarted yet again in its attempt to unload cargo and fuel at Australia's Antarctic base, Casey. The only compensation for the crew and passengers is that the Aurora Australis is cruising up and down what looks like a graveyard of gigantic icebergs,...
A hidden aquifer the size of Ireland recently discovered within the ice layers of a glacier in Greenland could hold the key to better understanding how annual melting at the ice surface could affect sea level rise. The Dec. 22 issue of the prestigious scientific journal Nature details the existence...
The predicament and subsequent rescue of 52 passengers – both tourists and scientists – on the Russian ship Academik Shokalskiy has gripped media around the world. The smooth rescue was impressive and a great relief, although the vessel itself and its crew are still stuck – and now one of the...
