I think it all depends on what you mean by "denial". There's legitimate denial and illegitimate denial. For instance, do we see a trend? I think the answer there is yes, and you have to really stick your head in the sand to deny it. Do we understand what the trend means? That starts to get a little more controversial. Do we understand what's going on? Again, there's room for debate to some degree. What are the long term implications of the trend? More room. Can we do anything about the trend? Massive amounts of room. Should we do something about the trend, if so what, and at what cost? Now the field is wide open.

The deniers would have you believe that nothing is happening, the most militant supporters would have you believe they understand completely what's going on and they have the solution. Neither is correct, but the militants like to group everyone who questions anything into the denier camp, which is really not helpful, nor is it good scientific practice, the deniers like to group anyone who sees something into the eco-wacko crowd, which is again not good scientific practice.

The truth is, people are impatient or don't want to see what they don't want to see. Unfortunately, good science takes time and sometimes reveals things we don't want to see, which just frustrates everyone.
