Water from the world’s shrinking glaciers was responsible for almost a third of the rise in sea levels between 2003 and 2009, shows new research.
An international team of scientist compared data gleaned from two NASA satellites as well as traditional ground measurements from glaciers around the world.
Their work, published in the journal Science , is the most accurate estimation of how glaciers contribute to sea level rises to date.
“For the first time, we’ve been able to very precisely constrain how much these glaciers as a whole are contributing to sea rise,” says lead author Assistant Professor Alex Gardner, assistant geography professor at Clark University in Worcester, Massachusetts.
“These smaller ice bodies are currently losing about as much mass as the ice sheets.”
The most significant ice losses occurred in Arctic Canada, Alaska, coastal Greenland, the southern Andes and the Himalayas, the study found.
The glaciers outside of the Greenland and Antarctic sheets lost an average of roughly 260 billion metric tons of ice annually during the period, leading to a rise in ocean levels of about 0.7 millimeters per year.
By contrast the glaciers in Antarctica, smaller ice masses that are not connected to the ice sheet, made scarcely any contribution to sea-level rise over the study period.
AMAP is one of five Working Groups of the Arctic Council.
The primary function of AMAP is to advise the governments of the eight Arctic countries (Canada, Denmark/Greenland, Finland, Iceland, Norway, Russia, Sweden and the United States) on matters relating to threats to the Arctic region from pollution, and associated issues.
Nearly 75% of Americans and 68% of Canadians indicated they “support” or “somewhat support” the project, which would carry heavy crude from the Alberta oil sands to the U.S. Gulf Coast for refining, according to the poll conducted by Ottawa-based Nanos Research.
The poll also asked participants—1,007 Americans and 1,013 Canadians—which was more important: reducing greenhouse-gas emissions or having North America free from oil imports? Both a majority of Americans and Canadians, 63% and 55%, respectively, suggested reducing reliance on oil imports trumped environmental policy.
“Energy security, particularly in the U.S., is driving views on energy issues,” said Nik Nanos, president of Nanos Research.
Environmentalists argue that development of the Alberta oil sands for the crude that Keystone would carry will increase emissions of greenhouse gases.
The Nanos poll contacted Americans between March 28 and April 7, and Canadians between April 6 and April 9.
The Obama administration is, for a second time, reviewing TransCanada’s application to build Keystone after rejecting the project in 2012. Keystone faces stiff opposition in the U.S. from environmental groups and key Democratic policy makers.
Nanos Research conducted the poll and they’re pretty legit. Via WSJ.
In a letter to top State Department officials, the agency said it had “environmental objections” to their review, which concluded the pipeline would have minimal impact on the environment. The analysis could complicate efforts to win approval for the controversial $7-billion project.
A State Department spokesman did not immediately respond to a request for comment.
If approved, Keystone XL would carry crude oil along a 1,700-mile route from the oil sands of Alberta, Canada, to refineries along the Texas Gulf Coast.

It will be approved. Nearly half of the line is already built, the land from Canada to Texas is already secured, Sec. State John Kerry signaled his support, and redstate politicians are salivating for a knockout punch to the environmental movement.
“The new rules are undemocratic. They attempt to restrict the public’s participation in these hearings and prevent a real dialogue about the environmental impacts of the Line 9 pipeline project,” said Adam Scott of Environmental Defence. “Canadians should not have to apply for permission to have their voices heard on projects that carry serious risks to their communities.”
Under the new rules, any Ontario resident who lives along the 639-km pipeline route who wants to send in a letter about their concerns must first apply to the NEB for permission to send in a letter. As of today, the public will have just two weeks to fill out a 10-page form which asks for a resume and references.
“Since when does someone’s resume determine if they have the right to be concerned about what’s happening in their home community?”

As dismantling begins, shuttering of research station called a ‘travesty’
The federal government says it is still trying to find a buyer for the world-renowned freshwater research station in Northern Ontario that it is closing at the end of this month, but it has already sent in a crew to start taking down buildings.
The news of the work came as a shock to scientists who rely on the decades of data that have been obtained at the ELA, the one-of-a-kind outdoor laboratory that has informed the world about the effects of contaminants such as mercury, acid rain and phosphorus.
Canadian government is aggressively shutting down science programs at all levels. Arguments to restore and recreate these programs in the future will be very difficult for Canadians to make, even if they elect a better political spectrum.

This has been sitting in my inbox for like a month. Had no idea how to respond until I came across this at Time: Google Searches Reveal Seasonal Trends in Mental Illnesses. It seems there is a way to measure illness by analyzing trends based on seasons, and I’m sure this technique could be adopted for your question on Canadians.
Google searches are becoming an intriguing source of health-related information, exposing everything from the first signs of an infectious disease outbreak to previously undocumented side effects of medications. So researchers led by John Ayers of the University of Southern California decided to comb through queries about mental illnesses to look for potentially helpful patterns related to these conditions. Given well known connections between depression and winter weather, they investigated possible connections between mental illnesses and seasons.
Using all of Google’s search data from 2006 to 2010, they studied searches for terms like “schizophrenia” “attention deficit/hyperactivity disorder (ADHD),” “bulimia” and “bipolar” in both the United States and Australia. Since winter and summer are reversed in the two countries finding opposing patterns in the two countries’ data would strongly suggest that season, rather than other things that might vary with time of year, was important in some way in the prevalence of the disorders.
Canada’s conservative government, which has been pressing the Obama Administration to approve the Keystone XL pipeline, has come under sharp criticism for allegedly muzzling Canadian government scientists who talk about the pipeline, climate change and other controversial topics.
The Environmental Law Centre at the University of Victoria released a report called “Muzzling Civil Servants: A Threat to Democracy” that documents the ways in which Prime Minister Stephen Harper’s administration has prevented public scientists from speaking freely about their research.
The Law Centre and Democracy Watch, a leading Canadian public accountability group, have requested an official inquiry into whether these practices violate Canada’s Open Government laws.
