College Park, Md. - The economic impact of climate change will cost a number of U.S. states billions of dollars, and delaying action will raise the price tag, concludes the latest series of reports produced by the University of Maryland's Center for Integrative Environmental Research (CIER). The new reports project specific long-term direct and ripple economic effects on North Carolina, North Dakota, Pennsylvania and Tennessee. In most cases, the price tag could run into billions of dollars.

The accuracy of computer models that predict climate change has been the subject of debate. A new University of Utah study shows that current climate models are quite accurate and can be valuable tools for those seeking solutions on reversing global warming trends. Most of these models project a global warming trend that amounts to about 7 degrees Fahrenheit over the next 100 years.
