Climate change could severely impact California's unique native plants
June 25, 2008 09:36 AM - UC Berkeley

The native plants unique to California are so vulnerable to global climate change that two-thirds of these "endemics" could suffer more than an 80 percent reduction in geographic range by the end of the century, according to a new University of California, Berkeley, study. Because endemic species - native species not found outside the state - make up nearly half of all California's native plants, a changing climate will have a major impact on the state's unparalleled plant diversity, the researchers warn.

Border fence will skirt environmental laws
June 24, 2008 03:17 PM - Los Angeles Times

In an aggressive move to finish building 670 miles of border fence by the end of this year, the Department of Homeland Security announced today that it will waive federal environmental laws to meet that goal. The two waivers, which will allow the department to slash through a thicket of environmental and cultural laws, would be the most expansive to date, encompassing land in California, New Mexico, Arizona and Texas that stretches about 470 miles.

So you've heard about all the pitfalls in the voluntary carbon offset market, and you still want to buy. How much is the right amount to spend? You might think that bargain shopping is a good idea--that it's no different than shopping around for the best deal on paper towels. In the carbon offsets industry, cheap offsets are the equivalent of off-brand condoms: they might be fine, but the stakes are so high they are not really worth messing around with.

Iowa: Agricultural Methods Exacerbate Flooding
June 24, 2008 09:28 AM - , Organic Consumers Association

In all of our reading about the floods and rebuilding Iowa, there is no mention of the role of agriculture in these recent events. Out of this catastrophe needs to come some understanding that industrial agriculture has caused many of the issues that happen downriver from cultivated land. A deterioration of good conservation and resource-management practices over the last 50 years has helped make these "rain events" even more catastrophic.

Analysis Shows Drastic Climate Change Near End Of Last Ice Age
June 23, 2008 09:17 AM - University of Colorado at Boulder

Information gleaned from a Greenland ice core by an international science team shows that two huge Northern Hemisphere temperature spikes prior to the close of the last ice age some 11,500 years ago were tied to fundamental shifts in atmospheric circulation. The ice core showed the Northern Hemisphere briefly emerged from the last ice age some 14,700 years ago with a 22-degree-Fahrenheit spike in just 50 years, then plunged back into icy conditions before abruptly warming again about 11,700 years ago.

The United Nations has called on more Asian leaders to agree to a plan to end deforestation by 2020 to slow down the destruction of plants and animals, a top official said on Friday. About 80 percent of the world's known biodiversity could be found in forests, where about 1.6 billion people also depend for their survival, Ahmed Djoghlaf, executive director of U.N. Convention on Biological Diversity (CBD), told a news conference in Manila.
