The trouble with climate change deniers is they turn everyone else into an equally unreasonable proponent. Look at these reactions to two pieces of evidence: Antarctica is losing ice from its ice sheets - It shows global warming is happening and things might get worse. Antarctica is gaining more ice than it's losing - We speculate that it might lead to another consequence that we haven't observed or modeled which would mean things still get worse. That's bias if I ever saw it. The fact is, we really don't know what will happen. Predictions range from 10m sea level rise in 50 years to nothing noticeable. It's a risk. A risk of things that might go very bad or might not. So we need to worry in case it does go bad. But the general public can't understand risk - they need black and white certainty which doesn't yet exist in this field. Proponents fear that people will choose black so they try to convince them it's white. Even though it's wrong, at least it seems like the safer choice of wrong.
