Is politics trumping science in the global warming debate? Well in January, a leading hurricane expert resigned from a top U.N. panel, charging that leaders were overstating the evidence to further a political agenda. Now, another prominent scientist has also resigned from an important government panel, making the same charge of politicized science. Roger Pielke, Sr., Colorado’s state climatologist, resigned from the U.S. Climate Change Science Program due to controversies about satellite and weather balloon data. He complained of premature representations of a report being made to the media, and concluded that if these panels have no intention of including minority, but scientifically valid viewpoints, then it would be best not to be involved at all.
