Changes

{{climate change}}Every day [[global warming skeptics]] feature prominently in newspapers, talk shows, TV programs and across the blogosphere disputing the overwhelming bulk of scientific evidence that greenhouse gas emissions are destabilizing the global climate.

All too commonly, media consumers are given scant background information on who they are, their scientific credentials (if any), any ties they have to corporate funded think tanks or past claims they have made that were incorrect. Some were defenders of the tobacco industry when they were affiliated with think tanks the tobacco companies funded. Some of these have now moved on to be deniers of global warming with think tanks that have been or are funded by fossil fuel companies such as [[Exxon]]. Not surprisingly, connections such as these are rarely included in the promotional materials circulated by the skeptics or groups such as the Heartland Institute.
