Geoengineering side effects could be potentially disastrous, research shows

Large-scale human engineering of the Earth’s climate to prevent catastrophic global warming would not only be ineffective but would have severe unintended side effects and could not be safely stopped, a comparison of five proposed methods has concluded.

Science academies around the world as well as some climate activists have called for more research into geoengineering techniques, such as reflecting sunlight from space, adding vast quantities of lime or iron filings to the oceans, pumping deep cold nutrient-rich waters to the surface of oceans and irrigating vast areas of the north African and Australian deserts to grow millions of trees. Each method has been shown to potentially reduce temperature on a planetary scale.

But researchers at the Helmholtz Centre for Ocean Research Kiel, Germany, modelled these five potential methods and concluded that geoengineering could add chaos to complex and not fully understood weather systems. Even when applied on a massive scale, the most that could be expected, they say, is a temperature drop of about 8%.

The potential side effects would be potentially disastrous, say the scientists, writing in Nature Communications. Ocean upwelling, or the bringing up of deep cold waters, would cool surface water temperatures and reduce sea ice melting, but would unbalance the global heat budget, while adding iron filings or lime would affect the oxygen levels in the oceans. Reflecting the sun’s rays into space would alter rainfall patterns and reforesting the deserts could change wind patterns and could even reduce tree growth in other regions.

The Union Backed Bluegrass Pipeline Problem


The Big Picture RT

Published on Feb 26, 2014

Cole Stangler, In These Times, joins Thom Hartmann. The Keystone pipeline isn’t the only environment-destroying pipeline project being considered in America today. Down in Kentucky – there’s a battle over another proposed pipeline – dubbed the Bluegrass Pipeline. But THIS pipeline would be environmentally safe, reduce our dependence on foreign oil and create tons of jobs, right? Well, that’s what the folks behind it are hoping you believe

Exclusive: Inside the Army Spy Ring & Attempted Entrapment of Peace Activists, Iraq Vets, Anarchists

http://www.democracynow.org – More details have come to light showing how the U.S. military infiltrated and spied on a community of antiwar activists in the state of Washington. Democracy Now! first broke this story in 2009 when it was revealed that an active member of Students for a Democratic Society and Port Militarization Resistance was actually an informant for the U.S. military. The man everyone knew as “John Jacob” was in fact John Towery, a member of the Force Protection Service at Fort Lewis. He also spied on the Industrial Workers of the World and Iraq Veterans Against the War. A newly made public email written by Towery reveals the Army informant was building a multi-agency spying apparatus. The email was sent from Towery using his military account to the FBI, as well as the police departments in Los Angeles, Portland, Eugene, Everett and Spokane. He wrote, “I thought it would be a good idea to develop a leftist/anarchist mini-group for intel sharing and distro.” Meanwhile, evidence has also emerged that the Army informant attempted to entrap at least one peace activist, Glenn Crespo, by attempting to persuade him to purchase guns and learn to shoot. We speak to Crespo and his attorney Larry Hildes, who represents all the activists in the case.

The True Cost of Economics

The RSA

Published on Feb 26, 2014

Dr Philip Roscoe argues that economics is not a science, it’s a way of thinking – one that skews all our choices towards self-interest. But now that our most urgent challenges require collective action, it’s time to think differently.
