Salt Lake City, UT – On Friday, the Intergovernmental Panel on Climate Change concluded that it is "unequivocal" that global warming is occurring. It also stated that it is at least 90% certain that humans are responsible. As the debate shifts from "Is it happening?" to "What do we do about it?" citizens, scientists and politicians are starting to look in their own back yards.
Right now, almost all of Utah's power comes from burning coal. But coal-fired power plants produce mercury emissions and greenhouse gases, which contribute to the heating of the planet.
Some Utah scientists say it doesn't have to be that way. Researchers at the University of Utah say coal can be clean -- for a price. Robin Sussingham has more.
