The State Department is delaying a decision for at least a year on whether to approve the Keystone pipeline. The $7 billion pipeline would carry oil from the tar sands of Alberta, Canada, through the U.S. to Gulf of Mexico refineries. Nebraska's state government and environmental groups have put intense pressure on the State Department and White House to reject the pipeline's proposed route. NPR's Richard Harris talks with Robert Siegel about the project.

Power plants that burn fossil fuels release carbon dioxide as well as a complex soup of chemicals, including nitrogen and sulfur. These chemicals in the air actually help keep global warming in check by reflecting sunlight back into space and by interacting with carbon dioxide. Above, the Bruce Mansfield Power Plant in Shippingport, Pa.
Cleaning up the air, while good for our lungs, could make global warming worse. That conclusion is underscored by a new study, which looks at the pollutants that go up smokestacks along with carbon dioxide.
These pollutants are called aerosols and they include soot as well as compounds of nitrogen and sulfur and other stuff into the air. Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air.
