A survey of television weathercasters conducted by George Mason University researchers shows that two-thirds are interested in reporting on climate change, and more than half are skeptics of the phenomenon.

The survey comes at a time when only a handful of TV news stations employ a dedicated science reporter.

Ultimately, the team hopes to turn TV meteorologists nationwide into a reliable source of informal science education about climate change.

E20 fuel, which blends 20 percent ethanol with gasoline, reduces the tail pipe emissions of hydrocarbons and carbon monoxide, compared with traditional gasoline or E10 blends, according to a new study in the Journal of Automobile Engineering. In addition, the research found no measurable impact to vehicle drivability or maintenance in conventional internal combustion engines.

E20, the study's authors say, could be used to reduce overall vehicle emissions at a time when many states and the U.S. Department of Transportation are considering policies that would increase the ethanol percentage in standard gasoline. The results are also being used by the Environmental Protection Agency to promote the federal Renewable Fuel Standard program.
