Nancy Pelosi just returned from Greenland where she says she saw proof of Global Warming, and proof that it is caused by man, particularly Americans. I wonder what she saw? This seems to me to be a totally ignorant statement because local climate cannot possibly be any indicator of a global phenomena. For example most of Antarctica has been getting colder over the last 30 years. If Nancy had gone there would she have concluded that a new ice age is coming? And, what could she have seen that clearly shows that Americans are causing whatever climate change is actually happening? I wonder if she realizes that 1000 years ago Greenland was warm enough for there to be farming there?
