It is tragic, unless there is even broader public outcry and political participation, that despite impressive scientific reports and warnings, Americans may yet look back and say "we should have known. The evidence, the truth, the warnings were all there. How could they have gone unheeded?"
What's the explanation for so many Americans becoming prisoners of the moment and ignoring strong scientific trends and the scientific community? Can a cool summer day or cloudy weekend really sway public opinion this much?
