In 2001 the Intergovernmental Panel of Climate Change (ICCP) concluded, based on a decade of research, that most of this increase is the result of burning fossil fuels. In a 2002 study requested by the Bush Administration, America’s National Academy of Sciences (NAS) confirmed the ICCP findings. A few weeks ago, NAS President Dr. Ralph Cicerone told me that today’s evidence is even more convincing; something must be done if we are to avoid destructive changes in climate.
In subsequent columns we will look at evidence connecting climate to warming, and some thoughts on what to do. Until then, rest assured that global warming is real, and that it will affect all of us.
Note: This is the first of three columns on global warming. Bruce Smart, of Upperville, was undersecretary of Commerce for International Trade in the Reagan administration.
