...that transcontinental migration is about to get even longer, thanks to global warming. In a new study in the Journal of Biogeography, scientists at the British universities Durham and Cambridge found that migration flights undertaken by warblers in Europe and Asia could be extended by as much as 250 miles by the end of the century. That's because as temperatures rise, the habitats of birds like the whitethroat, which breed in Europe, will need to shift farther north to more hospitable climates. But the birds' wintering grounds in Africa appear unlikely to shift northward - for reasons that still aren...
...destruction of the wetlands and other oases they might use as refueling stops along their flight path. Adding 250 more miles to the trip could be devastating. "These little birds push themselves to the limit of their endurance to fly these distances," says Willis. "Anything that makes these trips longer could be the difference between making it and not making...
...summers in the Mediterranean are having dire effects on the familiar fan-shaped coral, as well as on many other kinds of marine invertebrates. In a study published April 14 in the journal Proceedings of the National Academy of Sciences, they argue that for the Gorgonia and its kin, longer summers equal nothing short of mass death...
...Gorgonia, one of the most emblematic and significant corals in the Mediterranean, Ribes and Coma have found that seas have their seasons, too - and with equally dire effects. Between 1974 and 2006, summer conditions in the Mediterranean expanded by 40%, meaning the season has grown on average one day longer each year. For the Gorgonia and other sensitive suspension invertebrates - the term refers to the organisms' habit of feeding on particles suspended in the water - the added length has made an already tough season even tougher...
...likely the White House shares this view, even though in public it has harped on getting the North Koreans back to the six-party format. This is probably no longer possible, after Pyongyang's announcement yesterday. So the trick for Obama now is twofold. He must figure out how much time to let pass before trying to re-engage the North. (Even before the April 5 launch, Obama's special envoy, Stephen Bosworth, talked of letting the "dust from the missile [test] settle.") Then Obama must decide what to say to Pyongyang whenever the moment of reaching out arrives...
