...cuddly polar bear has become global warming's favorite mascot. It's also become a political flash point: on one side, conservation groups say global warming threatens the bear by permanently damaging its Arctic habitat. On the other, conservative groups say the so-called plight of the polar bear is a gambit to intensify climate change hysteria. The battle flared up again last Monday, when a California federal district court judge ordered the Fish and Wildlife Service (FWS), the Interior Department agency that evaluates endangered species, to decide on the polar bear by May 15 (a four-month extension...
...question is whether the polar bear is actually in enough danger to warrant official government protection. Last year, a study by the U.S. Geological Survey (USGS) concluded that two-thirds of the world's polar bears could disappear in the next 50 years if Arctic sea ice continues to evaporate at its current rate - sea ice is essential for polar bears, serving as the platforms from which they hunt. Similar discussion is ongoing in Canada, where two-thirds of the world's estimated 20,000 to 25,000 polar bears reside. Last week, a Canadian scientific committee ruled that...
...Propulsion Laboratory, just executed a dramatic dive through an icy geyser that reaches 950 miles (1,530 km) into space from the Saturnian moon Enceladus, and there are plans to follow that up with even higher-risk maneuvers. In May NASA's Phoenix Lander will set down in Mars' arctic region in search of water ice. And later this month NASA and the European Space Agency will retire their Ulysses solar surveyor after a 17-year mission that has reframed our understanding...
...going to tell you something I probably shouldn't: we may not be able to stop global warming. The Arctic Ocean, which experienced record melting last year, could be ice-free in the summer as soon as 2013, decades ahead of what the earlier models told us. We need to begin curbing global greenhouse emissions right now, but more than a decade after the signing of the Kyoto Protocol, the world has utterly failed...
Following Faust and Menino, Daniel P. Schrag, an earth and planetary sciences professor and the director of Harvard’s Center for the Environment, spent his speech describing the increasing atmospheric levels of carbon dioxide, the ensuing accelerated rate of Arctic ice melting, and the global repercussions of higher sea levels...
