Following record-breaking high global temperatures, both Arctic Ocean sea ice and Greenland’s massive ice sheet have responded with dramatic early seasonal melting. These conditions are likely to increase overall ice…
Arctic sea ice reached its annual minimum on September 11 this year and scientists say it appears the accelerated pace of sea ice decline has continued into 2015. According to…
On July 16, all five countries bordering the Arctic Ocean — the United States, Norway, Canada, Denmark, and Russia — signed an agreement that prohibits commercial fishing in the international…

One of the most iconic species of the ongoing climate change drama, polar bears (Ursus maritimus) have dropped in numbers as their habitat melts, with previous estimates forecasting a further…
It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get…
Sea anemones are supposed to sit on the bottom of the ocean, using their basal disc (or adhesive foot) to rest on a coral reef or sand. So, imagine the…
Thickly packed sea ice in the Arctic from a photo taken in 1949. One day thick, stable sea ice in the Arctic will likely be a thing of the past…
Sea ice cover in the Arctic shrank to one of its smallest extents on record this week, bringing forward the days of an entirely ice-free Arctic during the summer. The…
As sea ice levels continue to decline in the northern hemisphere, scientists are observing an unsettling trend in harp seal young mortalities regardless of juvenile fitness. While a recent study…
Rapid thawing of the Arctic could trigger a catastrophic "economic timebomb" which would cost trillions of dollars and undermine the global financial system, say a group of economists and polar…
Weather patterns around the globe are getting weirder and weirder: heat waves and record snow storms in Spring, blasts of Arctic air followed by sudden summer, record deluges and then…
Four young explorers including American actor Ezra Miller have planted a flag on the seabed at the north pole and demanded the region is declared a global sanctuary. The expedition,…
Melting sea ice, exposing huge parts of the ocean to the atmosphere, explains extreme weather both hot and cold Climate scientists have linked the massive snowstorms and bitter spring weather…

Few places are changing as rapidly as the Arctic due to global warming. Last year, scientists were stunned when the Arctic's seasonal ice extent fell to record low that was…
Arctic snowfall accumulation plays a critical role in ringed seal breeding, but may be at risk due to climate change, according to a new study in Geophysical Research Letters. Sea…
