Some Environmental Blogging

Beginning with the tar-sands, a new study says that high levels of toxic pollutants in Alberta's Athabasca River system are linked to the tar-sands project. The study led by Erin Kelly and David Schindler of the University of Alberta also found that levels of the pollutants cadmium, copper, lead, mercury, nickel, silver and zinc exceeded federal and provincial guidelines for the protection of aquatic life in melted snow or water collected near or downstream from oilsands mining. Follow this link and see why it's called "dirty oil."

While using the oil from the tar-sands is controversial and the American drug-store chain Walgreens has decided to switch suppliers, they are not boycotting using oil from the tar-sands project and neither are, as had been reported in some news outlets, The Gap, Levi Strauss and Timberland.

Climate change is on everyone's mind due to the increase in extreme weather events that have occurred this year around the world and yet as recently as last week ,while visiting Canada's North, Stephen Harper was still reluctant to talk about it let alone meet the challenge head on. This while visiting a region of our country that is now embroiled in a gold rush for Arctic riches, fueled by the massive changes in the climate which have affected the polar regions more dramatically than other portions of the country. So how much sea ice is out there? What's the extent and the volume? Well, follow this link and get some solid science and answers to these questions.

Of course climate change is unpredictable and the models aren't always going to get it exactly right, which is no reason to disregard all the research that points to a rapidly changing climate with human fingerprints all over it. Most importantly the predictions for the consequences of ACC (anthropogenic climate change) and the costs of our inaction are dramatic and frightening.
