Water is key


In both the estuary and the mountain range, a key question centers on water. With most climate models showing rising global temperatures over the next century, scientists fear that the marshes and channels of the delta will simply grow too warm for cool-water fish such as the Pacific salmon, as well as Central Valley steelhead, green sturgeon and the now-famous delta smelt.

The report notes that 12 of the original 29 native delta species are either extinct or endangered.

"The predictions for climate change related to sea level rise and increasing temperatures - paired with more demands for water and physical pressure on the delta levees - are going to create more stressors for salmon and many other fish," said Mark Rockwell, California coordinator for the Endangered Species Coalition.

Hundreds of miles away in the alpine forests of the Sierra Nevada, drier weather and higher temperatures could radically alter various habitats. For instance, a stream-fed meadow could turn into a barren, rocky field over a long-enough time span. In turn, species that lived in the meadow would have to move farther upslope to find a suitable home.


Story of the pika


The report highlighted the American pika as a kind of canary-in-the-coal-mine species, saying the cute, plant-loving cousin of the rabbit is disappearing from boulder fields in lower elevations as it struggles to find cooler ground.

U.S. Forest Service biologist Connie Millar agrees that the Sierra Nevada might become a harsher environment for some animals that wander atop the highest peaks, such as the alpine chipmunk and yellow-bellied marmot.

But Millar's recent research suggests the pika is much hardier and inhabits a wider range than previously thought. What's more, her 2010 study found that the animal had not abandoned warmer lower-level habitats as some other scientists have contended, lending credence to the argument that certain animals may be able to adapt to gradual changes in their environments.

Pika are "one of the more adaptable alpine mammals," Millar said. "Of course, if their habitat turned to rock and they had no vegetation, it would be harder. But the heat would have to spike up quickly."

Bumblebee species ‘in trouble’: US Study

CBC News, 4 Jan 2011



http://www.cbc.ca/technology/story/2011/01/04/bumblebee-population-delines.html
Four of the 50 species of bumblebees found in the U.S. are "significantly in trouble," University of Illinois entomology professor Sydney Cameron said Tuesday.

Cameron, lead author of the first in-depth national study of wild bees in the U.S., said the analysis only covered eight species, so "this could be the tip of the iceberg."

The finding echoes similar ones in other reports that documented huge declines in honeybee populations.

Using historical records from the late 1800s, Cameron and her colleagues found the relative abundance — the proportion of the studied species out of all bumblebees — of the four species decreased by up to 96 per cent since that period, and their geographic range contracted by between 23 and 87 per cent.

The study said that the declining populations had significantly higher infection levels of the pathogen Nosema bombi than unaffected populations. Separate research has shown that the parasite can render bumblebees helpless and unable to function, and eventually kill them.

The infected populations also had lower genetic diversity.

"Higher pathogen prevalence and reduced genetic diversity are, thus, realistic predictors of these alarming patterns of decline in North America, although cause and effect remain uncertain," the abstract of the study said.

Research last year on colony-collapse disorder, which led to the mass deaths of honeybee colonies, suggests the collapse might have been caused by a combination of viruses and the fungi Nosema apis and Nosema ceranae.

Cameron said there is no proven cause of the bumblebee declines, but climate change has contributed to European losses and habitat loss may affect certain specialized species.

The Committee on the Status of Endangered Wildlife in Canada last May said the rusty-patched bumblebee should be listed as endangered. Its rapid decline is a mystery, but pesticides, disease and a loss of habitat could be contributing factors.

The three-year U.S. study compared more than 73,000 museum records with recent U.S. national surveys of more than 16,000 specimens from about 400 sites.

The report was published in the Proceedings of the National Academy of Sciences.


Climate change brightens up the Arctic

Vancouver Sun, 6 Jan 2011, Marianne White



http://www.vancouversun.com/technology/Climate+change+brightens+Arctic/4067954/story.html
The 24-hour-a-day darkness that blankets the High Arctic three months a year is becoming brighter every year and, according to one observer, it's the result of global warming.

Wayne Davidson, a weather station operator in Resolute Bay -- one of Canada's most northerly communities -- said Inuit hunters have noticed for years that the dark Arctic night is becoming lighter.

Davidson started to study the phenomenon and posted photos of the sky on his website ( www.eh2r.com).

Eventually, he and other observers say, they figured out what was happening in the Far North.

"I believe it's related to temperature differences and the Arctic is becoming warmer than usual ever since 1998," the weather researcher said in an interview from Resolute Bay, where he has been living for 25 years. Basically, the warmer layer of air over the Arctic is acting as a conduit for light from the south.

"It's the refraction of light where the warm air and the cold air meet that is creating this brightness," Davidson explained.

The bigger the temperature differences, the longer the light travels and shines, he noted.

"It's a slow but gradual process that doesn't seem to want to stop," Davidson said. "It's astounding, there's no other word for it."

The new kind of light -- that takes various shades of blue, green and red -- has been noticed not only by residents in Resolute Bay, but also in other hamlets on Baffin Island.

"Nowadays, we also see the daylight much earlier," said Harry Alookie, of Qikiqtarjuaq. "It never used to be like that."

While some Arctic residents might enjoy winters that are not as bitterly cold as they used to be, it's a different story for Inuit hunters.

The rising temperature makes hunting difficult as prey disappears and thinning ice becomes treacherous.

"The impact is especially big this year," said Alookie, who manages the Nattivak Hunters and Trappers Organization in Qikiqtarjuaq.

The sea ice used to freeze up in November, but this winter the hunters were only able to go on the ice for the first time on Monday.

"It's making it a lot more difficult for people up here," Alookie said, noting that ice is of paramount importance for Inuit livelihoods.

There are about 70 full-time hunters in Qikiqtarjuaq and other residents, such as Alookie, are occasional hunters who go out on weekends.

"We have to be in communication with each other about which areas are safe and which areas are not," he added.

Scientists have said the Arctic is warming more quickly than the rest of the planet and Davidson has noticed it firsthand.

"It's been surprisingly consistently warmer than usual for the past few winters," he said.

For instance, the mean temperature for this past December was 8 C above the normal seasonal temperatures.

"It's huge," Davidson said. In the Nunavut capital of

Iqaluit, it has been raining since Monday and there is still open water in the bay.

The United States National Snow and Ice Data Center reported Wednesday that the extent of Arctic sea ice cover for December 2010 was the lowest on record, particularly in the Hudson Bay and Hudson Strait, south of Baffin Island.

Kent says oilsants unfairly demonized

Montreal Gazette, 5 Jan 2011, Renata D’aliesio



http://www.montrealgazette.com/business/Kent+says+oilsands+unfairly+demonized/4066212/story.html
CALGARY — Newly-minted Environment Minister Peter Kent says the oilsands have been unfairly demonized, trumpeting the resource as “ethical oil” and as an economic boon for the entire country.

On his second day in the federal environmental portfolio, the Toronto-area Conservative MP reiterated his predecessor’s pledge to enhance water monitoring in northern Alberta’s vast oilsands region.

However, he said, labels such as “dirty oil” and claims that bitumen extraction is the most destructive industrial activity on the planet are overblown.

“There has been a lot of disinformation and outright misinformation,” Kent said during an interview.

“There has been a demonizing of a legitimate resource. It is ethical oil. It is regulated oil. And it’s secure oil in a world where many of the free world’s oil sources are somewhat less secure.”

Alberta Environment Minister Rob Renner is looking forward to working with his new federal counterpart, said spokeswoman Erin Carrier. Renner hopes to secure a meeting with Kent to hash out mutual environmental challenges, such as climate change.

Kent, part of a small cabinet shuffle, replaces House leader John Baird, who held the position for an interim stretch after Albertan Jim Prentice’s resignation from cabinet in November.

Environmentalists want Kent and the Harper government to move more aggressively on reducing greenhouse gas emissions.

The Conservatives have set a goal of cutting the country’s carbon emissions to 17 per cent below 2005 levels by 2020, mirroring targets set by the Obama administration. Clare Demerse of the Pembina Institute, an Alberta-based environmental think-tank, said the federal government hasn’t outlined how it intends to achieve its climate change goal.

“We simply don’t have policies that would add up to actually reaching that target,” Demerse said. “Part of the problem there is the government’s decision to wait for the United States.”

Kent, who worked as a journalist before entering politics in 2008, dismisses the claim that Canada lacks a climate change plan. He noted Ottawa has implemented regulations focused on emissions from cars and plans to introduce draft regulations targeting heavy-duty vehicles later this year.

“Transportation, of course, is the biggest single segment of greenhouse gas emissions in Canada,” he said.

Also in the federal government’s crosshairs are coal-fired power plants. Draft regulations, expected in the spring, will not follow the United States’ recently announced path, Kent pledged.

“It really is apples and oranges,” Kent said of comparing Canada’s coal-fuelled electricity sector with the United States. Americans’ reliance on these power plants is much greater, he added.

“That’s simply a route we don’t have to go and we aren’t going to go, but the outcomes will be very similar.”

The U.S. Environment Protection Agency intends to propose emission-reduction rules for new and existing power plants. In contrast, the Harper government’s plan would require coal-fired electricity generators to eventually switch to natural gas or tap technology to capture and store their carbon emissions.

“The outcome will be the same,” Kent said.

David Collyer, president of the Canadian Association of Petroleum Producers, said Kent faces a steep learning curve as he familiarizes himself with issues facing the country’s energy sector.

Environmental issues surrounding oilsands development will likely be top of mind, he added. Collyer believes having an Ontario-based environment minister may help to better inform Central Canadians about the economic importance of the oilsands and what’s being done to reduce the mammoth development’s environmental footprint.

Sierra Club of Canada’s executive director John Bennett is calling for a halt on new oilsands projects. The oilsands are the country’s fastest-growing source of carbon dioxide.

“We need a moratorium on the oilsands until we figure out how we’re going to reduce our greenhouse gas emissions and how we’re going to clean up the mess in the oilsands region that’s already there,” Bennett said.

While Kent acknowledges water-monitoring improvements are needed in the oilsands region — recommended last month by a federal scientific panel — he said he believes the resource’s economic value to Canadians isn’t properly understood.

“We have to work to make sure that the misrepresentation of our oilsands resources … are countered with facts,” Kent said.
