Science is growing and changing and learning. Its not sticking its head in the sand and ignoring facts. Alma, I realized that with these guys its a paradox. They call people who show them that the phenomenon isn't occurring at a natural rate alarmist, and in at the same time lay blame immediately on the developing nations. So which is it, is it occurring or not? The reason the US administration is squarely to blame here is that they are openly denying it when their scientists are showing them otherwise. Here is a fiction;terrorism and supposed weapons of mass destruction. Its amazing how they have a habit of mixing up fact and fiction.
