Wired: "Scientists Rank Global Cooling Hacks"

Geoengineering, the concept of "hacking" the climate to undo years of carbon emissions, has grown in popularity recently as scientists — mad and otherwise — are churning out more and more supersized schemes. Two earth scientists have now ranked those schemes' effectiveness, finding that only stratospheric aerosol injections or sunshades in space would make a significant difference. 

• Fortune: "Wind jobs outstrip the coal industry"

— Jobs in wind power soared 70 percent from 2007 to 2008, with the industry now employing 85,000 people, compared with 81,000 jobs in the coal industry. Wind accounted for 42 percent of all new U.S. electricity generation installed last year, raising capacity by half, but that feat isn't likely to be repeated this year given the credit crisis.

• The Daily Green: "U.S. Beekeepers Have More Bees Than Anytime in 3 Years"

— Kim Flottum, editor of Bee Culture magazine and Daily Green blogger, offers some hope that the country's apiaries could be on the rebound, but warns it's too early to quit worrying about Colony Collapse Disorder. Better bee management, he writes, has helped cut losses to 2 percent this year, up from last year's dismal 35 percent. And there may even be 100,000 extra bee colonies in California at the moment, causing California almond trees to be "over-beed." 

New Scientist: "Cheap, super-efficient LED lights on the horizon"

— The European Union and the United States both have plans to phase out incandescent tungsten-filament light bulbs in favor of compact fluorescent bulbs, which are much more energy-efficient. While light-emitting diodes are three times more efficient than CFLs, they aren't part of the switchover plans because they're too expensive to manufacture commercially. But a new breakthrough in the U.K. could change that, making LEDs much cheaper to produce and possibly the brightest choice of all. "We should have stayed with tungsten for another five years and then switched to LEDs," one scientist says.
