Latest Arctic Sea Stories
Melting Arctic sea ice will mean colder winters with more snow in the Northern Hemisphere, according to a new study published Monday in the Proceedings of the National Academy of Sciences.
Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record.
Relatively accurate predictions for the extent of Arctic sea ice in a given summer can be made by assessing conditions the previous autumn, but forecasting conditions more than five years into the future depend on understanding the impact of climate trends on the ice pack, new research shows.
The area covered by Arctic sea ice during the summer reached a new all-time low on Thursday, with the summer sea ice extent falling to 1.64 million square miles (4.24 million square kilometers).
The fast-melting Arctic sea ice seems to be pushing the walruses out onto land, with many moving near the area where oil leases have been sold.
The melting of Arctic sea ice may temporarily stabilize, and the ice may even expand, over the coming years.
Danish researchers say the rate of melting in the Arctic sea may be slower than previously thought.
The 2011 Arctic sea ice extent maximum that marks the beginning of the melt season appears to be tied for the lowest ever measured by satellites.
The Northern Hemisphereâ€™s shrinking ice and snow cover is causing less and less sunlight to reflect back into space in a previously underestimated mechanism that could add to global warming.
