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.

The glacier, Solheimajokull, a tongue of ice reaching toward Iceland's southeast coast, has become an apologue of climate change in recent years: Retreating an average of one Olympic pool-length every year for the past two decades due to climbing temperatures, warming ocean currents and disrupted...
From reindeer to regional temperature patterns, from sea ice age to Greenland surface melt, the Arctic Report Card is a yearly assessment of the Arctic's physical and biological systems and how they are changing.
Satellites above the Earth are documenting a striking change in the Arctic. Not only is open water area increasing in the region, but adjacent land areas are growing “greener.” Since observations began in 1982, Arctic-wide tundra vegetation productivity has increased. In North America, the rate of...
A scientific mission ship, trapped in dense pack ice off East Antarctica since Christmas Day, is close to being rescued as a Chinese icebreaker nears.
Almost 50 people – half of them scientists, half of them paying members of the public who volunteer as assistants on the research projects – have been sailing through the Southern Ocean on board the Shokalskiy research ship, repeating and extending many of Mawson's wildlife and weather observations...
The Arctic continued to shift to a warmer, greener state in 2013. That was the headline from the latest Arctic Report Card , an annual update prepared by scientists from the National Oceanic and Atmospheric Administration (NOAA) and partner organizations such as NASA.
Big surprises still hide beneath the frozen surface of snowy Greenland. Despite decades of poking and prodding by scientists, only now has the massive ice island revealed a hidden aquifer.
Scientists have finally begun mapping one of the least explored regions of Antarctica - the Recovery Catchment.
With news out of San Francisco this week, at the autumn meeting of the American Geophysical Union (AGU), we learned scientists have incorrectly estimated the amount of ice being lost on the polar continent of Antarctica . This environmental faux pas directly affects the estimates on global sea...
The action is taking place at the Center for the Remote Sensing of Ice Sheets (CReSIS), a National Science Foundation-funded center at the University. Maintaining the fondness for synonyms, the mapping radar the scientists are using is known as the Multichannel Coherent Radar Depth Sounder or...
It looks like past IPCC predictions of sea level rise were too conservative; things are worse than we thought. That is the takeaway message from a new study out in Quaternary Science Reviews and from updates to the IPCC report itself. The new study, which is also discussed in depth on RealClimate...
The study, published in Geophysical Research Letters , discovered two subglacial lakes 800 metres below the Greenland Ice Sheet. The two lakes are each roughly 8-10 km2, and at one point may have been up to three times larger than their current size.
Ice sheets in Greenland are unequivocally losing its mass at an incredible rate due to the rise in the global temperature. Researchers looked at the hidden clues embedded in the Arctic fossil record to understand the history of ice sheets in Greenland.
Earthquakes deep below West Antarctica reveal an active volcano hidden beneath the massive ice sheet, researchers said today (Nov. 17) in a study published in the journal Nature Geoscience.
"Tiger stripes" of dirt and rock found far beneath Antarctic glaciers create zones of increased friction that act like speed bumps on the ice's otherwise steady march toward the sea.
