Houston Business Journal: A new study says the Keystone XL pipeline could produce four times as much global warming pollution as previously believed, the Associated Press reports. The new estimates, from scientists at the Stockholm Environment Institute, were published over the weekend by the journal Nature Climate Change. The earlier estimates by U.S. officials did not take into account that added oil from the pipeline would drop prices by about $3 a barrel and spur consumption that would then create more pollution,...

Grist: If the Keystone XL pipeline is built, it could lead to up to four times as much CO2 pollution as the State Department has estimated, according to a new study. And the study wasnt written by activists. It was conducted by scientists at the Stockholm Environment Institute and published in the journal Nature Climate Change. Why are these new figures so much higher than previous ones? The Associated Press explains: The U.S. [State Department's] estimates didnt take into account that the added oil...
Global Warming Will Make Toxic Algae Blooms Worse

Columbus Dispatch: Scientists say climate change is exacerbating toxic-algae problems in Lake Erie and across the country. They say more-intense storms are dumping heavy rains onto farm fields, causing more fertilizer runoff than in the past, and that lake-water temperatures are rising, making a perfect home for the toxic blue-green algae that plague Lake Erie every summer and caused Toledos recent drinking-water woes. When you have a gentle rain, where you get maybe an inch ... over a 24-hour period, you dont...

Keystone XL could be worse for climate change than US claims, say researchers

Toronto Star: The worlds most debated pipeline could be worse for global warming than previously believed, a new economic analysis says. Keystone XL could produce four times more greenhouse gases than the U.S. State Department calculated in January those estimates did not take into account that the added oil from the pipeline is likely to decrease prices and increase consumption which would probably create more pollution, researchers say. There is no indication that the State Department took the market...
Surprise! Keystone XL will make climate change worse

New Scientist: Try not to faint from shock. The controversial Keystone XL pipeline, which would carry Canadian oil through the US, will make climate change worse. It will boost global emissions of carbon dioxide by up to 110 million tonnes per year. The finding will step up the pressure on US president Barack Obama to stop the pipeline being built. That extra CO2 is not a huge amount on a global scale. "But it is a step in the wrong direction," says Jerry Schnoor of the University of Iowa in Iowa City, who was...
