Polar bears listed as threatened
Climate disruption cited as main threat to Arctic creature

The polar bear made it onto the U.S. endangered species list in the “threatened” category in May after several years of legal and scientific drama (SN Online: 5/14/08). Listings for corals mention climate change as a contributing peril, but the bear became the first species listed with climate change as the main threat. Polar bears are adapted to life on sea ice, and in 2007, the U.S. Geological Survey calculated that current climate models predict that by midcentury melting in the Arctic will reduce the current polar bear population by two-thirds.


Color-coded footprints indicate the dollar cost, in trillions, of environmental damage inflicted by high-, middle-, and low-income groups of nations on each of the other two groups.

Big foot  Rich nations are leaving supersized boot prints of ecological damage on poor countries. In the past four decades, the rich have passed up to $2.5 trillion in environmental damage onto the poor, eclipsing the poor nations’ debt of $1.8 trillion to wealthier countries (SN: 1/26/08, p. 52).

Return of the libraries  After facing strong political opposition, the U. S. Environmental Protection Agency agrees to reopen a number of the libraries that its staff and the public had depended on as a source of reports not available elsewhere (SN Online: 4/25/08).

Scientific interference  A survey of Environmental Protection Agency scientists finds most had experienced political interference during the past five years, such as being told to bury or misrepresent research data that might contradict Bush administration policies (SN Online: 5/8/08).

Burying bad news  By relying on journals, physicians and the public alike are getting a skewed picture of drug and therapy trials. In one study, researchers find that data from fewer than one in five research trials are ever published (SN Online: 9/24/08).  Another study shows that results of drug trials are often unreported and inaccessible to clinicians and patients (SN: 12/20/08, p. 14).

Swapping emissions-intensive red meat and dairy for vegetables, chicken or fish can be as powerful as reducing overall food miles.

Meat not miles  Reducing red meat and dairy intake lowers food-associated greenhouse gas emissions more than reducing food miles by buying local goods, suggests a food life-cycles analysis (SN: 5/24/08, p. 11).

Early thaws  In New Hampshire, the trend toward earlier spring thaws has significantly lowered logging revenues (SN: 1/5/08, p. 14).

Anthrax details  The FBI reports that DNA analyses of the anthrax sent by mail in the 2001 attacks revealed four signature mutations that were key in implicating Bruce Ivins. The Army microbiologist died of an apparent suicide in July while under investigation (SN: 9/13/08, p. 8).
