Some people do deny climate change. You will find plenty on the Internet. I for one found one in today's local newspaper, circulation ca. 1 million. The linked article stopped just short of explicitly denying climate change by calling climate change a "myth" and instead calls the consensus on climate change a myth. That people are skeptical is indeed down to us humans, and especially so to scientists like me who only come to a verdict after performing a lot of observations and pondering. In climate change politics however "climate change skeptic" is a euphemism for denialist.
