Seas could rise up to 1.6 meters by 2100

A report issued by the Arctic Monitoring and Assessment Program (AMAP) says global sea levels could rise by up to 1.6 meters by the year 2100.

Aggravated by a thaw of Greenland's ice, the rise will threaten many coastal areas from Bangladesh to Florida, as well as low-lying Pacific islands and cities such as London and Shanghai, Reuters reported.
According to the Oslo-based program, "the past six years (until 2010) have been the warmest period ever recorded in the Arctic."
Backed by the eight-nation Arctic Council, the program warns that "in the future, global sea level is projected to rise by 0.9 meters to 1.6 meters by 2100 and the loss of ice from Arctic glaciers, ice caps and the Greenland ice sheet will make a substantial contribution".
"Arctic glaciers, ice caps and the Greenland ice sheet contributed over 40 percent of the global sea level rise of around 3 mm per year observed between 2003 and 2008," it said.

Stealth helicopters kept under wraps until bin Laden raid

BLACK HAWK: Aftermath of crash exposes some secrets.
By ROBERT BURNS The Associated Press
Secret until now, stealth helicopters may have been key to the success of the Osama bin Laden raid. But the so-far-unexplained crash of one of the modified Black Hawks at the scene apparently compromised at least some of the aircraft's secrets.

The two choppers evidently used radar-evading technologies, plus noise and heat suppression devices, to slip across the Afghan-Pakistan border, avoid detection by Pakistani air defenses and deliver two dozen Navy SEALs into the al-Qaida leader's lair. Photos of the lost chopper's wrecked tail are circulating online -- proving it exists and also exposing sensitive details.

The reason one of the helicopters crash-landed at the bin Laden compound has not been disclosed, but Daniel Goure, a defense specialist at the Lexington Institute think tank, said Friday it might be explained by the unusual aerodynamics resulting from the aircraft's modificatio…
