As a scientist, I am outraged at Rick Santorum's statement denying the validity of the dangers posed to the planet from climate change and global warming. What credentials does he have to make any statement about this highly complex scientific subject?

His position is completely contrary to the one supported by the great majority of U.S. scientists, the National Academy of Sciences and NASA. Perhaps he will soon advise us on the intricacies of brain surgery or rocket science, about which he is equally knowledgeable.
