United States: Climate changes chomp away at Cape

Cape Cod Online: Erosion, that hungry land-eating beast, may be getting a power boost around Cape Cod as climate change kicks up higher sea levels and increases storm intensity and frequency. That was the hatch-battening message from Cape Cod National Seashore GIS specialist Mark Adams, a mapping guru who has been trying to decipher how flooding and erosion brought on by accelerated coastal processes might affect Seashore properties -- roads, parking lots and historical structures -- as time munches on. Owners...

South Korea probes second report of U.S. army chemical dumping

Reuters: South Korea opened a second investigation in days into a report that the U.S. military dumped toxic chemicals near the capital decades ago, a Defense Ministry official said on Wednesday, threatening to trigger an anti-American backlash. Experts have been sent to the former U.S. base in Bucheon, west of Seoul, to check out the claims after South Korean media reported that a U.S. veteran had said "hundreds of gallons" of chemicals were buried there between 1963 and 1964. The accusations could rekindle...

Central China drought ‘worst in over 50 years’

AFP: Central China's worst drought in more than 50 years is drying reservoirs, stalling rice planting, and threatens crippling power shortages as hydroelectric plants lie idle, state media said Wednesday. Rainfall levels from January to April in the drainage basin of the Yangtze, China's longest and most economically important river, have been 40 percent lower than average levels of the past 50 years, the China Daily said. The national flood and drought control authority has ordered the Three Gorges...

Bacteria ‘abound in hailstones’

BBC: A study of hailstones has found large numbers of bacteria at their cores. The find lends credence to the "bio-precipitation" idea, which suggests that bacteria are actively involved in stimulating precipitation. The bacteria have protein coatings that cause water to freeze at relatively warm temperatures. Researchers at the American Society for Microbiology meeting suggest bacteria may have evolved to use the water cycle to facilitate their own dispersal. The micro-organisms that can...

China power crunch to worsen as drought slashes hydro output

Reuters: The worst drought to hit central China in half a century has brought water levels in some of the country's biggest hydropower producing regions to critical levels and could exacerbate electricity shortages over the summer. The official Xinhua news agency said on Wednesday that the water level at the world's biggest hydropower plant at the Three Gorges Dam in Hubei province has fallen to 152.7 meters, well below the 156-m mark required to run its 26 turbines effectively. Total capacity at the...
