Polar bear price increase

01/04/2012

“Just as Ottawa is drawing up polar bear management plans and mulling the animal’s promotion to National Symbol, the Northwest Territories is now paying an extra $1,350 for polar bear hides.

Hunters in the Northwest Territories used to receive $400 when they submitted polar bear pelts to Genuine Mackenzie Valley Furs, a government-run fur marketer. For this season, authorities have upped the figure to $1750.  …

As Russia and China produce more billionaires, offices and homes bedecked in Arctic fur have become a sought-after status symbol. Threats to polar bear populations posed by melting sea ice have only sweetened the deal.  …

Every year, about 450 polar bears are killed and skinned in Canada — largely by Inuit hunters in Nunavut. Northwest Territories officials maintain that their new advance will not create a run on polar bears.  …

In Canada, polar bear hunting is the exclusive domain of aboriginals, although outsiders can commission sport hunts with aboriginal guides. While pelts are sold, the polar bear’s meat is shared among communities. Polar bear hunting is an “integral part of Inuit identity,” reads a July paper on polar bear populations by the Department of the Environment.  …

Amid the threat of melting sea ice, Mr. [Andrew E.] Derocher [a biologist with the University of Alberta] said researchers rarely take issue with polar bear hunting. “I don’t know a polar bear scientist that hasn’t support subsistence harvests of polar bears — or even sport hunting of polar bears,” he said.”  “N.W.T. ups price paid for polar bear pelts to $1,750 as demand for the fur rises

Willi Dansgaard passes — L.A. Times botches obit

02/07/2011

The L.A. Times notes the passing of pioneer ice core scientist Willi Dansgaard but neglects to mention that the “clear link between carbon dioxide and methane concentrations and global temperatures” found in his ice cores shows that CO2 and CH4 increase follows temperature increase, not vice versa:

Willi Dansgaard, a Danish paleoclimatologist who was the first to recognize that the Earth’s climatic history was stored in the Greenland ice cap, died Jan. 8 in Copenhagen, according to the Niels Bohr Institute at the University of Copenhagen. He was 88.

His research, together with that of Claude Lorius of France and Hans Oeschger of Switzerland, revolutionized scientific knowledge of how the temperature and composition of the atmosphere have changed over the last 150,000 years, demonstrating a clear link between carbon dioxide and methane concentrations and global temperatures.  “Willi Dansgaard dies at 88; scientist who recognized climate record in ice cap

Warmest year ever!

“Of the past 10,500 years, 9,100 were warmer than 1934/1998/2010.  Thus, regardless of which year ( 1934, 1998, or 2010) turns out to be the warmest of the past century, that year will rank number 9,099 in the long-term list.”  “2010 – where does it fit in the warmest year list?

Science versus alarmism and advocacy

05/22/2010

Abstract: A continuous data set of Greenland Ice Sheet altimeter height from European Remote Sensing satellites (ERS-1 and ERS-2), 1992 to 2003, has been analyzed. An increase of 6.4 T 0.2 centimeters per year (cm/year) is found in the vast interior areas above 1500 meters, in contrast to previous reports of highelevation balance. Below 1500 meters, the elevation-change rate is –2.0 T 0.9 cm/year, in qualitative agreement with reported thinning in the ice-sheet margins.  Averaged over the study area, the increase is 5.4 T 0.2 cm/year, or È60 cm over 11 years, or È54 cm when corrected for isostatic uplift. Winter elevation changes are shown to be linked to the North Atlantic Oscillation.”  “Recent Ice-Sheet Growth in the Interior of Greenland”  h/t The Hockey Schtick

“[S]cientists at the University of Miami say Greenland’s ice is melting so quickly that the land underneath is rising at an accelerated pace.  …

“It’s been known for several years that climate change is contributing to the melting of Greenland’s ice sheet,” Dixon says. “What’s surprising, and a bit worrisome, is that the ice is melting so fast that we can actually see the land uplift in response,” he says. “Even more surprising, the rise seems to be accelerating, implying that melting is accelerating.”

Dixon and his collaborators share their findings in a new study titled “Accelerating uplift in the North Atlantic region as an indicator of ice loss.”  The paper is now available as an advanced online publication, by Nature Geoscience.  …

Melting of Greenland’s ice contributes to global sea level rise. If the acceleration of uplift and the implied acceleration of melting continue, Greenland could soon become the largest contributor to global sea level rise, explains Yan Jiang, Ph.D. candidate at the University of Miami RSMAS and co-author of the study.

“Greenland’s ice melt is very important because it has a big impact on global sea level rise,” Jiang says. “We hope that our work reaches the general public and that this information is considered by policy makers.””  “Greenland Rapidly Rising as Ice Melt Continues

AP journo in wonderland

What planet is this AP journo living on?

“The European Space Agency is launching a satellite that scientists hope will help them pin down the effects of global warming on the Earth’s ice packs more precisely.

The CryoSat 2 mission, which starts Thursday after years of delays, will be able to pinpoint details of changes in polar ice so scientists can better understand the alarming picture of the world’s retreating ice caps.  …

For coastal cities and islands, the information may be a question of survival.

If all of the Earth’s polar ice and glaciers were to melt, sea levels could rise up to 230 feet (70 meters), Miller said.

If only Greenland became ice-free, it would mean a 21.33-foot (6.5-meter) rise, he said.”  “EU satellite to check climate change impact on ice

Meanwhile, on planet Earth, arctic sea ice is at its 30-year average, antarctic sea ice continues to grow, and:

"Rotten" ice again

01/21/2010

What do you do when arctic sea ice increases, contrary to AGW dogma?  Why say the ice is “rotten” of course:

In early September 2009, satellite measurements implied that most of the ice in the Beaufort Sea either was thick ice that had been there for multiple years or was thick, first-year ice.

However, in situ observations made in September 2009 by Barber et al. show that much of the ice was in fact “rotten” ice — ice that is thinner, heavily decayed, and structurally weak due to a uniform temperature throughout.

The authors suggest that satellite measurements were confused because both types of ice exhibit similar temperature and salinity profiles near their surfaces and a similar amount of open water between flows. The authors note that while an increase in summer minimum ice extent in the past 2 years could give the impression that Arctic ice is recovering, these new results show that multiyear ice in fact is still declining.  Ice is ‘rotten’ in the Beaufort Sea

Yikes! Invading trees!

01/12/2010

“Contrary to scientists’ predictions that, as the Earth warms, the movement of trees into the Arctic will have only a local warming effect, University of California, Berkeley, scientists modeling this scenario have found that replacing tundra with trees will melt sea ice and greatly enhance warming over the entire Arctic region.

Because trees are darker than the bare tundra, scientists previously have suggested that the northward expansion of trees might result in more absorption of sunlight and a consequent local warming.

But UC Berkeley graduate student Abigail L. Swann, along with Inez Fung, professor of earth and planetary science and of environmental science, policy and management, doubted this local scenario because, while broad-leaved trees are dark, they also transpire a lot of water, and water vapor is a greenhouse gas that is well-mixed throughout the Arctic.

Taking account of this in a standard model of global warming, the researchers discovered that, while broad-leaved trees do absorb some additional sunlight, the water vapor they pump into the atmosphere causes a more widespread warming.”  “Trees invading warming Arctic will cause warming over entire region, study shows

Nothing new in Greenland

“Annual Greenland temperatures were higher in 1930 than today. The rate of warming in the past was much greater than the current rate of warming. Greenland warmed fastest before the concentration of greenhouse gases increased substantially. Greenland cooled substantially from 1930 to 1980 … during a period of greenhouse gas concentration increase. Box et al. note in their abstract that “The annual whole ice sheet 1919–32 warming trend is 33% greater in magnitude than the 1994–2007 warming.”” “A Christmas story: some facts about Greenland

Quote of the day

12/11/2009

The great truth-monger Al Gore claimed yesterday that 40% of the Artic Ice Cap has already disappered, and that the other 60% will be gone in 5, 10, or 15 years. If almost half of the Artic ice has already melted, then why aren’t London, New York, Miami, Venice, Houston, Singapore, etc., under water?” — Christopher Monckton

“John P.
