"Climate change" is too vague a term to have any meaning.Do you believe there is any climate change caused by humans?
Assuming that you're asking whether man-made emissions have at least some small effect on the Earth's temperature, the answer is yes, I believe that. So do Richard Lindzen, Judith Curry, John Christy, etc., etc.
Do I believe the influence is significant? Based on the observed data, of course not.
Do I believe the predictions about how man-made emissions would affect the planet were accurate? Of course not. So far, the predictions for the 21st century have been consistently and spectacularly wrong.
Do I think the IPCC has any credibility? Certainly not.
Do I believe there is any reason to worry? Of course not.
Do I think that people who believe the minor changes in the Earth's temperature over the past 150 years are overwhelmingly due to natural factors should be characterized as believers in "anthropogenic climate change"? No, that's pure idiocy.
