War and Peace Over Holdren's Climate Testimony - ScienceInsider

When his turn to question Holdren arrived, Rohrabacher began by requesting permission to submit the names of 100 climate scientists who disagree with the consensus on global warming, including people Rohrabacher described as prominent academics.
