The new research takes a closer look at how multi-year ice, ice that has made it through at least two summers, has diminished with each passing winter over the last three decades. Multi-year ice extent is diminishing at a rate of -15.1 percent per decade, the study found.
The decline in extent and area of multi-year ice has accelerated during the last decade.
The thicker ice, known as multi-year ice, survives through the cyclical summer melt season, when young ice that has formed over winter just as quickly melts again. The rapid disappearance of older ice makes Arctic sea ice even more vulnerable to further decline in the summer, said Joey Comiso, senior scientist at NASA Goddard Space Flight Center and author of the study, NASA’s web site reads.
“The average thickness of the Arctic sea ice cover is declining because it is rapidly losing its thick component, the multi-year ice. At the same time, the surface temperature in the Arctic is going up, which results in a shorter ice-forming season,” Comiso said.
Multi-year sea ice hit its record minimum extent in the winter of 2008. That is when it was reduced to about 55 percent of its average extent since the late 1970s, when satellite measurements of the ice cap began. Multi-year sea ice then recovered slightly in the three following years, ultimately reaching an extent 34 percent larger than in 2008, but it dipped again in winter of 2012, to its second lowest extent ever.
Russia’s only aircraft carrier, the Northern Fleet’s “Admiral Kuznetsov”, has finished repairs and is ready to leave the port of Murmansk. According to a Russian news agency, the vessel will sail to Syria.
A century and a half ago, Norway was home to roughly three thousand brown bears, the majority of bears in all of Scandinavia. By 1930, the bears were virtually extinct. Decades of aggressive management tactics and bounties had wiped out one of the area’s most iconic species.
Microplastics, the tiny plastic particles that are accumulating in marine waters and big lakes around the world, are now showing up in the Arctic waters south and southwest of Svalbard, Norway, a new study says.
REYKJAVIK: The climatic changes taking place in the Arctic are a call to action for the world. We must answer with more international cooperation and more research, says Tore Hattrem, State Secretary of Norway’s Foreign Ministry.
“Partnership should and shall shape the development of the Arctic, therefore cooperation is the starting point for our Arctic policy,” Vladimir Barbin, Senior Arctic Official and representative to the Arctic Council, said at the Arctic Circle 2015 assembly.
August 9th, the Barents Region celebrated the UN International Day of the World’s Indigenous Peoples. The day was commemorated in several parts of the region, including Karasjok in Northern Norway and Teriberka in Northwestern Russia.
Norway’s Foreign Minister Børge Brende has asked Russia for an explanation to the high number of asylum seekers coming to Norway via Russia. Syrian refugees that have lived in Russia for a long time, will be stopped on the border and sent back.
