Here is another possible explanation for why a lot of people say the climate is changing. It has to do with data and evidence, rather than pure politics.

Too bad there isn't a clear explanation on WHY the climate is changing.
I think the real answer is that it is complicated and not just due to one cause. This gives the pundits and the PR people a golden opportunity to politicize the issue, which should be about temperature data and other objective stuff.
And don't forget plain old common sense. There just isn't much of it in the world these days.

Of course, they don't really believe in it (as most of the public and scientists also do not believe)as you can tell from their actions.
Yet some uneducated people will go blissfully on their way as Climate-gate deniers.
