I watched the hearing on C-Span last night. Republican buttheads were still pushing the real scientists to admit that the scientific consensus is not unanimous, and not 100% certain. The scientists, of course, admit this freely because NOTHING in science is ever 100% certain. EVERYTHING is always open to doubt and critical testing and possible revision. That is how science works fer crissakes. These R-jerks are playing upon (and fostering) public misunderstanding of science so they can keep the big oil campaign contributions rolling in. They are selling out my (and yours, and everyones') kids' future for bags of silver.
