Atmosphere May Cleanse Itself Better Than Previously Thought  - BBC  A research team from Purdue University and the University of California, San Diego has found that the Earth's atmosphere may be more effective at cleansing itself of smog and other damaging hydrocarbons than was once thought. Scientists, including Joseph S. Francisco, have learned that some naturally occurring atmospheric chemicals react with sunlight more effectively than previously thought to produce substances that "scrub" the air of smog. This group of chemicals, after absorbing energy from sunlight, is able to break down smog and other pollutants into far less harmful components. This observation has eluded science primarily because photochemistry at these wavelengths has been difficult to study. "We now have a better understanding of an atmospheric process that could be giving our pollution-weary lungs more breathing room." 
Climate: A Message From The Plankton?  - BBC  Left:  Phytoplankton take up CO2, die and sink to the bottom, which removes greenhouse gases from the atmosphere - but it also makes the food unavailable for consumption by many ocean animals.  Modern climate observers can be divided into groups conveniently called worriers and skeptics. Most climate scientists reside in the former, warning the build-up of carbon dioxide in the atmosphere - already at higher levels than in at least the past 30,000 years - is bound to produce harmful effects on the planet's ecosystems. It is true some plant growth increases with higher CO2 concentrations, but most scientific studies show this benefit is limited; it is constrained by other factors.  

Britain May Need Another Generation Of Nuclear Power Plants  - BBC  Britain may need one more generation of nuclear power stations to help meet a target to reduce carbon dioxide emissions in the fight against global warming, the government's top science advisor said Thursday. "I've never been a great nuclear protagonist." But he said the question of climate change and its impacts on human society -- "the most serious problem we're faced with globally this century" -- was so important that the nuclear option had to be re-examined.
