EMBED

SUMMARY: Lou Dobbs again questioned the impact of humans on global warming and suggested that solar activity may be far more responsible for global warming, ignoring the conclusion by the United Nations' Intergovernmental Panel on Climate Change that "it is extremely likely [>95% chance] that humans have exerted a substantial warming influence on climate" and that this "estimate is likely to be at least five times greater than that due to solar irradiance changes."
