...that bit of fact-checking is looking a lot less convincing with the publication of a study on Tuesday in the Proceedings of the National Academy of Sciences. Lead author Lonnie Thompson, a glaciologist at Ohio State University who has been to the summit of Africa's tallest mountain repeatedly over more than a decade, says that while the glaciers did start melting a century ago, their retreat has sped up dramatically in recent years. "We've lost 26% of the ice since 2000 alone. And that, unfortunately, is just what we predicted would happen." Within a few decades...
...other scientists insist that melting, if it's occurring at all, has a relatively minor effect. "The fact that you have melting may mean air temperatures have increased, but it doesn't necessarily," says Philip Mote, who heads the Oregon Climate Change Research Institute at Oregon State University. "And in fact, the temperature on the summit of Kilimanjaro is essentially always below freezing, which makes it hard to accept warming as the reason [for glacier loss...
...Indeed, the state's data suggest that chronic underlying conditions are among the main risk factors for developing H1N1 disease severe enough to require hospital care. In both young and old patients who were hospitalized for swine flu (741 cases in total), ailments that complicate the flu were common: some 60% of children and 72% of adults had conditions including high blood pressure, high cholesterol and gastrointestinal disease. (See how to prevent illness...
...California data also reveal a potentially new risk factor for H1N1: obesity. Obese individuals were disproportionately represented in the state's sample of hospitalized cases - 58% of adults age 20 or older registered as obese, and 43% of these morbidly so. Those with excessive body-mass-index measurements tend to have other medical conditions related to weight that may put them at risk of suffering more severe infection with H1N1. Being overweight can increase sleep apnea and reduce lung function, for example, both of which can impair a heavier person's ability to overcome a respiratory infection like influenza. Among...
...denying that Obama and his agenda played a role. Some conservatives are turned off by the Administration's enacted and proposed expansion of government; some liberals are demoralized by Obama's failure to push their agenda. A McDonnell win would serve as a check on Democratic momentum in a state Obama won in 2008 after no Democratic presidential candidate had been victorious there in a generation, and signal a modest GOP comeback against the tide of last year.
