WWF Climate Blog Has Moved to New Location

The WWF climate blog now is located at a different Web address: worldwildlife.org/blogs/wwf-climate-blog.  All posts since May 2013 are at that location, while older posts will remain archived on this site.  The new site will have a single RSS feed at worldwildlife.org/blogs/wwf-climate-blog.rss.

New WWF web tool maps Arctic nature and activities

As Arctic Council Ministers prepare to meet to outline priorities for the Council’s next two years, WWF has released a mapping tool to help inform those priorities, ArkGIS.

U.S. Unveils Arctic Strategy while Announcing that Atmospheric Concentrations of Carbon Dioxide Have Surpassed Historic Level

The White House on Friday (10 May 2013) released a National Strategy for the Arctic Region, as the National Oceanic and Atmospheric Administration announced that daily average atmospheric concentrations of carbon dioxide (CO2) had on 9 May surpassed for the first time on record 400.00 parts per million (ppm) at the Mauna Loa Observatory in Hawaii. The rise in CO2 concentrations, largely driven by the burning of coal, oil and natural gas, is rapidly warming the Arctic.  The strategy acknowledges that “the current warming trend is unlike anything previously recorded” and that “there may be potentially profound environmental consequences of continued ocean warming and Arctic ice melt.” The document recognizes the Administration’s “global objective of combating the climatic changes that are driving these environmental conditions.” But the strategy also invokes U.S. security interests to argue that that “[c]ontinuing to responsibly develop Arctic oil and gas resources aligns with the United States `all of the above’ approach to developing new domestic energy sources.” In the absence of a U.S. low-carbon development strategy, is not clear how the U.S. ultimately will reconcile expanded fossil fuel production in the region with its commitment to combat climate change.

Scientists Release Findings of Arctic Ocean Acidification Assessment, Warn of Emerging Impacts on Vital Commercial Fisheries

An international group of scientists on Monday (6 May 2013) released the findings of their Arctic Ocean Acidification Assessment.  The Arctic Monitoring and Assessment Programme (AMAP), which commissioned the research, said in a press release that the Arctic Ocean "is rapidly accumulating carbon dioxide (CO2) leading to increased ocean acidification...This ongoing change impacts Arctic marine ecosystems already affected by rising temperatures and melting sea ice."   AMAP warns that "Arctic Ocean acidification has the potential to affect both commercial fisheries that are important to northern economies, and marine resources that are used by Arctic indigenous people." 

Tracking Pacific Walrus: Expedition to the Shrinking Chukchi Sea Ice (video)

This twelve minute video from the U.S. Geological Survey (USGS) starts with the biologists describing some of the many endearing qualities of walruses,  explaining how important sea ice is to the animals and why the decline of that ice is so disruptive and threatening -- not just to the walruses but for the people of the region.  The second half of the video shows how USGS biologists use satellite radio tags to track the movement and behavior of the walruses. "The information identifies areas of special importance to walruses during sparse summer sea ice and as human presence increases in the region from oil drilling and activities such as shipping and tourism now possible with less ice," says the USGS. In addition to the video, we provide a transcript.

With Inadequate Sea Ice North of Alaska, Walruses Haul-Out Along Russian Coast

We reported last week (26 September 2012), that sea ice in the Chukchi Sea north of Alaska had declined to the point where the National Ice Center had characterized an area preferred by walruses (Hanna Shoal) as open water. Without the sea ice they needed to rest on, walruses were headed ashore in search of a suitable area of coastal land where they could "haul out." We and others expected large numbers of walruses to haul out in the area of Point Lay, Alaska, where they have hauled out in recent years. But most of the walruses instead opted to continue swimming far to the West, to haul out in the vicinity of Russia's Cape Serdtse-Kamen -- joining other walruses already hauled out there. Though we cannot yet confirm that large numbers of walruses are hauling out at the remote cape, that certainly was the case last year. By mid-October 2011, an estimated (and astounding) 100,000 walruses from both the U.S. and Russian sides of the Chukchi, had hauled out there.

Sponsored by the Wildlife Conservation Society at the New York Aquarium at Coney Island to support its work to save walruses.  Check-in and registration opens at 7:00 a.m. Runners start at 8:00 a.m. and the Family Fun Run/Walk starts at 8:45 a.m.  See registration and other information at the Run for the Wild Web site.

In Alaska's Chukchi Sea: Shell Resumes Offshore Drilling as Nearby Walruses are Forced Onshore

The story of this year's Arctic sea ice decline did not end on 16 September when the sea ice reached its official minimum extent for the Arctic overall. The decline has continued in the Chukchi Sea -- with momentous consequences. While the National Ice Center indicated that a large "marginal ice zone" was present north of Alaska on 16 September, that zone continued to decline and on 24 September the marginal ice zone had been entirely replaced by open water.

With Record Low Sea Ice Extent, Polar Bears Persevere on Marginal Ice -- or on Land

On Saturday, 15 September -- the day before the Arctic sea ice extent reached its record low -- a scientist aboard the USGS Healy spotted a polar bear struggling across thin ice.  Her photos capture a situation facing growing numbers of polar bears as sea ice extent declines, and the ice grows thinner, in response to warming conditions. The bears must persevere on marginal ice or swim in search of suitable sea ice -- both far from preferred coastal waters; or they must abandon the ice altogether and swim to land.

Losing the Top of the World: Breaking the Arctic Sea Ice One Record at a Time

In our world of information overload, we get used to hearing of records being broken. Even so, some moments stand out -- including now the record low Arctic sea ice extent reached earlier this month.   When we look closer, this and the many other climate-related records events we've witnessed in recent years are not isolated, but connected. And in this new era of extremes, we aren't just breaking records. By continuing to pour carbon pollution into the atmosphere we are rewriting the rulebook for the future of life on Earth.
