Newspaper Article About Crow Sham’s Trip to the Arctic

The article below recently appeared in a Sinhalese newspaper in Toronto about Crow Sham's trip to the arctic. Some of her great pictures were used in the article, which she tells has a few extrapolations by the author about Sham's background and the project. So if you can read it take the article with a grain of salt and if you can't enjoy some great pictures of the True North on a hot day (at least where this Crow perches!).

'Eureka moment' provides unique opportunity for students #westernu


Western News reporter Jason Winders quoting Crow Emily in: 'Eureka moment' provides unique opportunity for students
“Suspenders. Don’t forget suspenders,” McCullough said. “We’re both kind of short. All of our Arctic gear, which is loaned to us, even the super-powered snowpants, are a little on the big side. So the suspenders keep your pants up. But, it’s even better than that.
More Arctic Life Advice from Crow Emily to cheechako Crow Sham on their current Arctic travels in the article. Emily is safely back South and Sham is continuing to run the lidar as part of the Canadian Arctic ACE/OSIRIS Validation Campaign.

CANDAC’s Eureka Observatory Featured in the #GlobeAndMail #GlobeNorth

Crow Emily is featured in this timely article on the important scientific work being done in the Canadian high arctic at Eureka:
For Emily McCullough, a Ph.D student at the University of Western Ontario who is working at the lab, its key benefits include the powerful lessons she’s learned about how to do professional research, from planning a major experiment to anticipating problems like “what happens if the wolves come and chew my cables.” 
But it’s also a place where she feels the work she does has an impact on Canada’s relationship to the rest of humanity. “Canada’s got a heck of a lot of the Arctic,” Ms. McCullough says. “It would be really great if we could contribute something to the understanding of it as a whole.”

Arctic scientists see Canada slipping on world stage

Arctic scientists see Canada slipping on world stage | Toronto Star

Yet increasingly, the basic science that would let us understand changes occurring in our own backyard — and either mitigate or take advantage of them — is being neglected by Canada and assumed by other countries, Arctic researchers say.

Austerity does not mean out-sourcing your future. As our Anthem says: “The True North strong and free!” Would it be cynical to suggest that since the most dramatic changes in climate due to human activity occur in the polar regions it is best to ask as few questions about the North as possible?

Duck sets the Record Straight on Canadian Arctic Science

the PEARL observatory in winter

Disturbing words from Canada’s Enviroment Minister Peter Kent. This past week he wrote a letter to the Victoria Times-Colonist mis-representing several important facts about the Harper Government’s brutal, targeted cuts on Arctic science. Prof. T. Duck (Dalhousie University) replies to Kent’s misrepresentation of the facts in a letter to iPolitics.ca, concluding:

… point-by-point Kent’s claims about PEARL are factually incorrect. Many other claims in the Times-Colonist letter have been so profoundly discredited that it is no small wonder he had the gall to utter them. This past week, in response to criticism he had “misled Canadians”, Kent told an opposition MP that she should talk to “better informed scientists”. What we really need is a better-informed Minister.

I encourage you to read the rest of Prof. Duck’s letter on iPolitics.ca.

When Opinion Trumps Scientific Reason #TheMark #PEARL #ozone #EnvironmentCanada

Or the ideological basis for federal cuts to environmental spending.

The closure of Canada’s Polar Environment Atmospheric Research Lab (PEARL) has shocked many Canadians. Located at 80°N in the High Arctic on Ellesmere Island, Nunavut, PEARL is the northernmost civilian research laboratory in the world. It is internationally recognized for ozone and climate research, and helped discover the first-ever Arctic ozone hole in 2011. PEARL is a Canadian success story that one U.S. government scientist deemed a “national treasure.” Now, many are left wondering why the Canadian government decided to bury that treasure.

Like most university-based environmental-research programs, PEARL depends upon federal grants to operate. However, in recent years, funding opportunities for projects like PEARL have been narrowed or eliminated. Government support for PEARL’s main sponsor, the Canadian Foundation for Climate and Atmospheric Sciences was cut off. Funding that was promised for climate and atmospheric science in the 2011 Federal Budget has been held up for nearly a year. The impact of this funding gap is far from benign. It has forced some of Canada’s best researchers to leave the country to find work. These experts were cultivated in Canada over many years and at great cost. It will take a generation to replace them.

Related: Environment and Economics: A False Dichotomy

The funding crisis at our universities mirrors the ongoing cutbacks at Environment Canada (EC). In July 2011, the government announced that it would eliminate 776 positions from EC, with 300 staff to be declared surplus. The cuts are undermining important research and monitoring programs in ozone, atmospheric radiation, climate adaptation, environmental toxics, air quality, and airborne research. Canadians depend upon these programs to ensure their environmental security, health, and safety.

How, then, can the government sufficiently defend these cutbacks?

It’s possible that a scientific review conducted by knowledgeable experts could provide the appropriate justification. However, no such review has taken place. At the 2012 World Economic Forum in Davos, Prime Minister Stephen Harper said that Canada’s investments in science and technology have produced poor results and are a “significant problem for our country.” Given the lack of expert assessment, however, his comments are without merit: They represent his unscientific opinion, and nothing more. Scientists the world over are lamenting what is happening to Canada’s scientific community.

Canadian governments once understood that good policy is informed by science. In 1988, Brian Mulroney’s Progressive Conservatives commissioned independent experts to conduct a review of EC’s ozone program. The resulting report (“Measuring the Impacts of Environment Canada’s R&D: Case Study: Stratospheric Ozone Depletion Research,” 1998) stated that for every dollar spent on the program, Canadians received almost $13 in benefits to their health, environment, and economy. Health benefits included the avoidance of over 57,000 cases of skin cancer, 30,000 cases of cataracts, and 625 deaths in Canada over a 60-year period. Unfortunately, the Harper Conservatives have sought to dismantle what the Progressive Conservatives saw worthy of support.

What’s particularly concerning is that the cuts to Canada’s environmental-monitoring programs are not about money. PEARL costs $1.5 million per year to operate, and EC’s ozone program likely costs about $1 million per year. Compare these costs with those of the government’s flagship programs: The budget for purchasing and servicing one F-35 fighter jet ($246 million, based on calculations from numbers given here) would power PEARL half way into the next century. The budget for new prisons ($9.5 billion) might have seen PEARL into the next ice age. The cost of gazebos and other perks that were built for Muskoka in the run-up to the G8 meeting of 2010 ($50 million) would have supported EC’s ozone program for the next 50 years. The budget for the War of 1812 celebrations ($28 million) could have supported either program for decades.

If money is not the issue, then why is the Canadian government so bent on making cuts to environmental spending? Harper made this clear last year during a trip to the Arctic, when he opined that environmental concerns cannot be allowed to stand in the way of economic development. This is a dangerous attitude. The economy doesn’t exist independent of the environment. A 1990 report from the United Steelworkers explains it best: “The real choice is not jobs or environment. It’s both or neither. What kind of jobs will be possible in a world of depleted resources, poisoned water and foul air, a world where ozone depletion and greenhouse warming make it difficult even to survive?”

Unfortunately, the government has systematically reduced scrutiny of the impacts of its economic and environmental policies by eliminating or crippling important research programs like PEARL. The widespread muzzling of EC scientists has further removed expert opinions from the debate. Clearly, the government cannot protect the future health and safety of Canadians and Canada’s economic viability without reliable information about environmental change. Yet, that is exactly what it is trying to do. It is the triumph of ideology over reason.

Op-ed piece from The Mark by Prof. T. Duck of Dalhousie. We continue to ask the question of why funding has been cut for Arctic ozone research when the amount of funding needed to continue this work (per year) is LESS THEN 5% OF RUN-UP COSTS OF THE G8 MEETING IN MUSKOKA (which was actually held 3.5 hours away in Toronto)?

Money, for a change, does not appear to be the issue here.

Why Canadians should care about the closure of the PEARL Observatory. #CANDAC @westernu @lfpress @aguscipolicy @saveec @createarcticsci

Why Canadians should care about the closure of the PEARL Observatory

Yesterday we announced the closure of the Polar Environment Research Laboratory (PEARL) located in the high Arctic at Eureka, Nunavut. And what should disturb Canadians about this news has nothing to do with scientific entitlement, belief or disbelief in climate change or signalling our failure as a nation to be able to honour international agreements and commitments. We should be disturbed by the rejection of the notion of our sovereignty by the current Government. Sovereignty has been a cornerstone of the Canadian identify for hundreds of years. Sovereignty is a part of the Canadian mystique, our world-renown ability to stickhandle through difficult situations and find common ground and compromise in chaos.
The current Government has in recent months, in addition to closing the PEARL facility, attempted to stop all ozone research by Environment Canada as well as successfully eliminated the Canadian Foundation for Climate and Atmospheric Sciences (CFCAS). This well-coordinated attack on atmospheric science has two major implications for our sovereignty.
  1. Developing policy. Traditionally when governments are trying to determine future policy actions they need information on which to base their decisions. For instance, how will changing climate affect Canadian agriculture? What affect will future climate changes have on air quality? If the Government is successful and rids itself of scientists investigating climate and weather issues, and further is successful in cutting support to University researchers, where is it going to get its information to make decisions? If you are in business and want to make a plan should you rely on your competitors (e.g. other nations) to provide the best possible advice to benefit you?
  2. Health of citizens. Another important function of government is risk assessment. For instance, when the Antarctic Ozone Hole was discovered and was found to be growing its affects on humans was felt in New Zealand. It was critical for their government to be informed and know what was happening locally. Last winter measurements from the PEARL Observatory were a critical part of showing the first significant Arctic ozone losses that were at a level of the Antarctic Ozone Hole. We feel it is a responsibility of the Government to monitor atmospheric air quality so they have the knowledge necessary to bring forward policies protecting the health of Canadians. Do we want to rely on getting this information from other nations?
For a Government that has made mention many times about sovereignty, particularly in the context of the Arctic, the closure of the PEARL observatory is particularly troubling. So are we to accept the plan is to just “develop” the Arctic and let’s not bother with any informed thought on how we go about doing that? That logic was prevalent in the 19th century expansion across North America, but we learned some hard lessons from that experience we should not forget. The Government’s logic that Canada’s loss of an existing high Arctic research facility is compensated for by a plan to possibly build a facility in 2017 located 1600 km to the South is unacceptable (FYI 1600 km is about the distance from Toronto to Atlanta, Georgia!).
If your Canada includes homegrown scientific research into the environment to allow informed policy decisions and you want Canada to keep a scientific presence in the high Arctic to protect our sovereignty you can write to your MP, the Prime Minister and Minister Kent and let them know how you feel about the closure of the PEARL facility. Contact information is given at the end of this article.

#CBCNews High Arctic research station forced to close

via cbc.ca
Sadly today marks the official announcement of the closure of Canada's PEARL Observatory. We have been unable to secure funding, primarily because we no longer have any government atmospheric or climate programs we can apply to for funds. The new observatory promised for 2017 is 1300 km to the south and is not in the high Arctic. Being in this location was important for being able to take measurements last spring during the largest Arctic ozone hole yet observed.

Canada dropping the #ozone ball, scientists warn - Politics - CBC News

37890600-media_httpwwwcbccagfx_pnJks

via cbc.ca
The CBC has picked up the AGU EOS article. I noticed the first commenter saying if EC thinks it is important they should cut something else. I would ask what would you do if your income was suddenly cut in half? Cut eating so you could heat your home? Live in a tent and eat better? Don't natter on about EC and priorities. Unless you think they should eliminate providing weather forecasts in Ontario to pay for their ozone program! Or do you believe they should outsource forecasting to another met service?

Ouch! From @theAGU #EOS: #EnvironmentCanada Cuts Threaten the Future of Science & International Agreements #ozone

Top American Atmospheric Scientists conclude:


We are concerned, in light of the Environment Canada budget cuts, that the international community may no longer be able to rely on the exceptional efforts and past leadership role provided by Canada for Arctic research. 

The Harper government is turning it's back on Canada's "True North" stewardship by implementing draconian cuts to ozone science that will not allow Canada to fulfil several international treaties it is party to including the Montreal protocol (how ironic!) and the US-Canada Air Quality agreement.

High Arctic troposphere is cleaner in the summer than the winter?

 The role of scavenging in the seasonal transport of black carbon and sulfate to the Arctic


Key Points

  • Arctic aerosol have a strong seasonal cycle that is dominated by wet scavenging

  • Both soot and sulfate are affected nearly equally by wet scavenging processes

  • We can anticipate from this study that a warmer Arctic will be a cleaner Arctic

Paul Novelli, GMD, ESRL, Boulder, Colorado, USA



In a prior study, a decade-long dataset of ground-based aerosol and carbon monoxide measurements from Barrow, Alaska (71°N, 157°W) was used to show that surface air in the Arctic is clean during the summer, less due to inhibited transport of pollutants from mid-latitudes, and more because of efficient wet scavenging at temperatures near freezing. Here, the analysis is extended to light-absorbing aerosols, such as black carbon, and to measurements from Alert, Canada (82°N, 62°W). The data imply that both light scattering and light absorbing aerosols have similar seasonal cycles, independent of location, and they are controlled nearly equally by wet scavenging. Removal is particularly efficient at high relative humidities and warm temperatures, which suggests that a future warmer and wetter Arctic may also be cleaner. Assuming aerosol pollutants generally have a warming effect in the Arctic, such an increase in wet scavenging would represent a negative Arctic climate feedback.

This recent paper uses aerosol and temperature measurements from Barrow and Alert to show that warmer, wetter summers cause the air at high latitudes to be cleaner in the summer than the winter. No quite what I expected, I'll have to look into this further.
