As reported by Andrew C. Revkin in the New York Times (May 28, 2008, p. A14), "The rise in concentrations of carbon dioxide in the atmosphere from human activities is influencing climate patterns and vegetation across the United States and will significantly disrupt water supplies, agriculture, forestry and ecosystems for decades." Among the more sobering conclusions of the report are the predictions of wide-spread water shortages in the western U.S., with dire consequences for populations and agriculture, and the migration of invasive species adversely impacting ecosystems throughout North America.
Healthy biodiversity, essential for ecosystem maintenance, is predicted to suffer as species struggle to adapt to rising temperatures, and conditions that encourage parasitic-induced disease as well as competition for resources and suitable reproductive habitats. From the Executive Summary: "The resilience of many ecosystems is likely to be exceeded this century by an unprecedented combination of climate change, associated disturbances (e.g., flooding, drought, wildfire, insects, ocean acidification), and other global change drivers (e.g., land use change, pollution)."

Despite listing polar bear as a species requiring protection under the Endangered Species Act, the first such listing attributed to loss of habitat due to global warming, Interior Secretary Dirk Kempthorne said it would be "inappropriate" to use the listing as an impetus to address global warming generally or reduction of greenhouse gases specifically.

"Frogs, salamanders and other amphibians are on a slippery path to extinction. Habitat loss, disease, global warming and other factors are taking their toll. Worldwide, a third of these key players in the web of life are considered threatened -- making amphibians the most vulnerable group of animals in the world.
"This month, Defenders Magazine profiles the plight of these slick critters -- and takes a look at what people are doing to save them."

Tune into NPR.org for yesterday's story on Oberlin's Fearless campaign. It's interesting listening, and Dan Bobkoff of member station WCPN in Cleveland does a good job of presenting different points of view.
All Things Considered, May 1, 2008 · A top-notch Ohio college's two-year-old marketing campaign — "We Are Oberlin: Fearless" — is the subject of internal mockery from Oberlin students.
Thanks to Kolleen for sharing this.
