Despite you getting sick at hearing "denier, denier", the fact remains that a significant number of the public and in politics deny there's a problem in the first place. How can you expect people to agree on a solution when we can't agree on the problem ?
I would suggest sheer perseverance of publishing the science in the face of such unfounded denialism will eventually do the trick, in the same way that it worked to convince the public of the link between smoking and cancer despite the opposition from vested interests at the time. The attacks on the science and scientists that we see today is very much the same tactic used by the tobacco industry and conservative organisations against doctors who claimed that smoking was dangerous.
In the end, science will win over politics (just like it did with tobacco, asbestos, etc). Those "significant number of the public and in politics" who claim to know better than all the climate scientists of the world will look more and more out of touch with reality as the temperature records keep getting broken.
In fact, the deniers have put a lot of stock in the current slow-down of temperature increase, and once it starts accelerating again (as it has done numerous times when there have been similar slow-downs over the last century) then it will cause great damage to their public support. If you remember back 5 years or so years ago, many deniers were claiming that it was actually getting cooler in comparison to the El Nino year of 1998. Once the record temperatures started happening again they silently dropped that claim, although it still hasn't stopped a lot of people from still bringing up how some people considered global cooling to be a possibility back in the 1970s. How convenient that they forget their own side's similar mistakes.
