Since 1989, the U.S. government has spent over $77 billion on policies related to climate change, including science and technology research, administration, education campaigns, foreign aid, and tax breaks. About $30 billion of that went to pure scientific research. None of that research has yet been able to point to a single piece of empirical evidence that man-made carbon dioxide has a significant effect on the global climate.
