U.S. EPA Weighs In: Keystone XL Climate Impact Not Adequately Addressed
2013-04-24 14:58:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: The U.S. Environmental Protection Agency (EPA) has challenged the State Department on its draft environmental impact statement on the Keystone XL pipeline, objecting to its conclusion that the Keystone XL presents no significant climate change impact or environment risk. This criticism raises an important hurdle in the overall executive review process for its approval, and gives the pipelines opponents additional support in their fight against the project. The U.S. EPAs challenge comes alongside...

EPA on Keystone XL: Significant Climate Impacts from Tar Sands Pipeline
2013-04-24 02:11:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: In a draft assessment of the proposed Keystone XL pipeline, consultants for the U.S. State Department judged that building it would have no significant impact on greenhouse gas emissions. Why? Because the analysts assumed the tar sands oil would find a way out with or without the new pipeline. The U.S. Environmental Protection Agency does not agree. Keystone XL's ability to carry an additional 830,000 barrels of tar sands oil per day is vital to expanded production of the tarry crude in Alberta....

Inter Press Service: Advocacy groups here are applauding the publication of new government concerns, formally expressed Monday by the U.S. Environmental Protection Agency (EPA), over a recent assessment of the environmental impact of a major oil pipeline that would run between Canada and the U.S. Gulf Coast. Because the EPA will eventually have to sign off on any decision to approve the pipeline proposal, made by a Canadian company called TransCanada, this indication of the agency's strong reservations over the government's...

Keystone species could cause ecosystem to collapse
2013-04-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
MSN: There are certain animals worldwide that hold a heavier sway in the balance of ecosystems, and they were dubbed "keystone species" in 1969 by American zoology professor Robert T. Paine. The theory is that like the wedge-shaped keystone (or headstone) that locks together all the pieces used in an architectural arch, there are species that keep certain ecosystems in together. Removal of the species can cause the eventual collapse of the ecosystem. Just a drop in the bucket of the keystone species...
