Warming appears to be having bigger impact on ice at higher elevations
Glaciers high in the Himalayas are dwindling faster than anyone thought, putting nearly a billion people living in South Asia in peril of losing their water supply.
Throughout India, China, and Nepal, some 15,000 glaciers speckle the Tibetan Plateau, some of the highest land in the world. There, perched in thin, frigid air up to 7,200 meters (23,622 feet) above sea level, the ice might seem secluded from the effects of global warming.
But just the opposite is proving true, according to new research published last week in the journal Geophysical Research Letters.

Plan B for a Warming Planet
Nov. 10, 2008 -- Earth needs a "Plan B" in the fight against global warming, in case efforts to curb greenhouse emissions fail or are inadequate, said an American scientist in testimony Monday to the British government.
Such a backup plan would probably need to involve climate engineering projects to deliberately counteract the effects of global warming. The engineering ideas that have been floated in recent years include injecting sunlight-blocking compounds into the upper atmosphere or building a gigantic structure in space to filter sunlight reaching Earth.

Dusty, Polluted Air Spawns Tornadoes
Deadly twisters routinely rip across the American Midwest each spring, and the Southeast each fall and winter. Just how they form is a mystery, but a new study suggests dust pollution in the atmosphere may nudge supercell thunderstorms into spawning tornadoes.
David Lerach of Colorado State University and a team of researchers compared two computer models of supercell storms -- one in which the atmosphere was clean, and one in which it was riddled with microscopic dust particles.
In the clean model the telltale rotating cloud formed, but no twister ever materialized. In the polluted version, which had 10 times more dust, it did.

A 'climate czar' in the Obama White House?
Activists float the idea; Gore has 'no intention,' spokeswoman says
Environmental groups see Barack Obama’s presidential victory as a chance to undo the Bush legacy on global warming, and one idea they are discussing is the possibility of a White House “climate czar”.
Activists say such a post could oversee various government agencies, including the Environmental Protection Agency and the Interior Department, to focus on tackling global warming and fostering clean energy to jump-start the flagging economy.
“For the first time, candidates and voters are really connecting the dots between energy, the environment and the economy,” said Cathy Duvall, Sierra Club’s political director. She said at a news briefing that Obama had made it clear that investing in cleaner energy would be a top priority in his plan for economic recovery.
