There's new evidence from an Antarctic ice core that the popular image of the melting poles doesn't quite fit reality at the southern one. Elizabeth R. Thomas of the British Antarctic Survey and colleagues report in Geophysical Research Letters that snow accumulation has doubled since 1850 in the western Antarctic peninsula, and that the trend [...].

The US National Institutes of Health invests $28bn annually in research. European spending is lower, although the European Union is closing the gap, helped by a shortsighted American policy of &quot;flatlining&quot; many scientific research budgets. (Perhaps this is because scientists have an annoying tendency to discuss things that conflict with the Bush administration&#39;s view of reality, such as global warming, evolution, the insufficiency of the New Orleans levee system and the medical potential of stem cells.)

An analysis of 20 years' worth of real-life observations supports recent U.N. computer predictions that by 2050, summer sea ice off Alaska's north coast will probably shrink to nearly half the area it covered in the 1980s, federal scientists say.
