Anything to try to make solar work

President Barack Obama says carbon pollution limits need to be set on U.S. power plants in order to curb global warming.

Obama says rules are already in place to limit pollution from arsenic, mercury, lead and other substances, but no federal limits exist on how much carbon pollution that power plants — including many that are fired by coal — can dump into the air.

Obama says "that's not right, it's not fair, and it needs to stop."
