Not only are greenhouse gases a major force that is driving global warming, but their impacts on temperature change is also now known to be greater than initially thought. On top of that, annual global temperatures are continuing to accelerate. We have determined that, based on the average of a set of complex atmospheric model projections, the temperature will increase in the United States in each of its regions throughout the first half of the twenty-first century in both winter and summer.
