Whether the Weather is Changing

It seems that everyone (from climate change scientists to people with an interest in selling more gas) have an opinion on climate change. We all experience the weather and 'know' what's happening to us. There is a new update on the latest science in this area (http://www.theguardian.com/environment/2013/sep/21/climate-change-ipcc-global-warming) but it seems that more and more of the general public are thinking the the scientists have got this thing wrong. Of course, you can't absolutely prove anything with science but you can determine probabilities. How many of us you argue against the protection offered by vaccinations (I know that small cohorts do) or that antibiotics can be useful in treating bacterial disease? There are areas where the general public trusts the collective view of scientists and others where they don't. Strangely enough, the latter examples often appear to involve situations where the contras have well-funded campaigns by vested interests.
