Your opinion could be paid for by ExxonMobil

As material from the web site of Sen. James Inhofe makes Slashdot's front page in what is basically an ad hominem attach on a Weather Channel meteorologist, the tactics of ExxonMobil in using smoke, mirrors and hot air to slow our response to global warming is revealed by the Union of Concerned Scientists. From the Executive Summary:

In an effort to deceive the public about the reality of global warming, ExxonMobil has underwritten the most sophisticated and most successful disinformation campaign since the tobacco industry misled the public about the scientific evidence linking smoking to lung cancer and heart disease.

It goes on to say that information laundering was used to attempt to confuse the public.

If you don't know that fear, uncertainty and doubt (FUD) is being fed to you, how can you be sure your opinion is your own?
