Are there any short-term solutions to climate change? One potentially quick fix being bandied about in India is the replacement of old cooking stoves that produce Earth-warming, lung-clogging black carbon (a.k.a. soot).
Soot accounts for 18 percent of greenhouse gas emissions, second only to carbon-dioxide (CO2), which accounts for 40 percent of the emissions blamed for global warming, according to today's New York Times. Scientists including Veerabhadran Ramanathan, an atmospheric physicist at the Scripps Institution of Oceanography in San Diego, are promoting solar-cookers as a quick fix to the soot problem while more complex technologies are developed to reduce the CO2 emissions, the Times reports.

Just how many months of life is clean air worth? Five to be precise, according to a new study published today in the New England Journal of Medicine.
"Who would have thought you could get almost half a year in increased life expectancy on average just from cleaning up our air somewhat?" says study co-author Arden Pope, an environmental economist at Brigham Young University in Provo, Utah. "That seems to me like a pretty good investment" in clean-air programs.
Pope and Harvard University colleagues compared improvements in air quality with increased life expectancy between 1980 and 2000. Their findings, based on air-monitoring and health data from 51 U.S. metro areas: five months of the nearly three additional years of life tacked on during that period stemmed from cleaner air.
