That is a literal interpretation of the words "climate change denier."
It's meaning in the cultural zeitgeist, however, has evolved to include people who don't deny that the climate does change over time, or even is currently changing; but, who deny the science supporting anthropogenic climate change, specifically the clear impacts to atmospheric CO2 starting during the industrial revolution and driven primarily by fossil fuel emissions.
Essentially, I think most people would agree at this point that the common usage also includes people who deny we can/should do anything about climate change, or that the current situation vis-a-vis greatly accelerated climate change is our "fault."
The records re: CO2 are not hard to find, they come from ice cores and date back ~800,000 years.
