And it is science denial to have a scientific opinion that is interpreting facts differently then the consensus?

Also, from my first source:

"The IPCC supports the overwhelming scientific consensus about human impact on climate change, so we would expect the reports' vocabulary to be dominated by greater certainty on the state of climate science -- but this is not the case."

The IPCC assigns a level of certainty to climate findings using five categories of confidence and ten categories of probability. The team found the categories of intermediate certainty predominated, with those of highest certainty barely reaching 8% of the climate findings evaluated.

"The accumulation of uncertainty across all elements of the climate-change complexity means that the IPCC tends to be conservative," says co-author Professor Corey Bradshaw, Matthew Flinders Fellow in Global Ecology at Flinders University. "The certainty is in reality much higher than even the IPCC implies, and the threats are much worse."
