Reducing emissions of short-lived climate pollutants, such as methane and black carbon, alongside carbon dioxide could help reduce the warming of the Arctic by up to 0.25 degrees by 2050, says a new report by the Arctic Council.
With climate change opening up the Arctic, a pact regulating commercial fishing in the region is urgently needed.

The Antarctic is a continent surrounded by oceans. The Arctic, in contrast, is an ocean surrounded by continents. The relatively shallow, increasingly ice-free waters of the Arctic Ocean constitute the last unexploited fishery on Earth.

A/OPS: Destined to be subject of derisive maritime pub songs?
Michael Byers & Stewart Webb, 24 April 2013, TheTyee.ca
Peter MacKay is no stranger to maritime pubs. He could probably recite the words of Stan Rogers' Barrett's Privateers while drunk and standing on his head. But does Canada's defence minister realize that he's fast becoming the 21st-century version of Elcid Barrett, who led a group of blindly ambitious men on a dangerous folly?
The North Pole stands to become a viable international shipping route for some vessels in coming decades, as melting ice clears the way for cargo movement through corridors never before considered possible.
Canada’s radar leader has scored a coveted space deal with Ottawa.
MacDonald Dettwiler and Associates Ltd. has landed a $706-million contract with the Canadian Space Agency, bolstering the satellite technology developer’s key Radarsat Constellation project, which is being touted as crucial for defending Canada’s Arctic sovereignty.
Oslo - Local pollution in the Arctic from shipping and oil and gas industries, which have expanded in the region due to a thawing of sea ice caused by global warming, could further accelerate that thaw, experts say.
The United Nations Environment Programme (UNEP) said there was an urgent need to calculate risks of local pollutants such as soot, or “black carbon”, in the Arctic. Soot darkens ice, making it soak up more of the sun's heat and quickening a melt.
ABOARD USS NEW HAMPSHIRE, Arctic Ocean | Mon Mar 21, 2011
(Reuters) - The machine that produces fresh air aboard the USS New Hampshire submarine failed during a mission under the vast ice cap of the Arctic Ocean last week, prompting the submarine to use an alternate oxygen candle system instead.
Arctic Ocean sea ice has experienced another severe meltdown this year, with the approaching end-of-summer minimum representing the third-biggest thaw since satellite monitoring began about 30 years ago.
This year's retreat from a winter maximum of about 15 million square kilometres to a September coverage area of just five million square kilometres also means that the four greatest melts since satellite measurements began in the late 1970s have occurred in the past four years.
The head of the largest climate change study ever undertaken in Canada says the Arctic sea ice is thinning faster than expected.

"It's happening much faster than our most pessimistic projections," said University of Manitoba Prof. David Barber, the lead investigator of the Circumpolar Flaw Lead study. A flaw lead is the term for open water between pack ice and coastal ice.
