The worst mistake ever. . .
. . .was the emails sent that included warnings to other scientists who did not agree with the mainstream. Science should be open to all opinions and only be served by facts. If a theory is based on foolishness it will show it's face soon enough. No scientists should be threatened with cut off of funds or publishing or anything else. Let the truth shine. Otherwise you are no better that the tobacco companies and their research.
Now you have half of the Americans believing that global warming or climate change is just an attempt to control all the research dollars. Very tragic.
