To be honest, credible climate change scientists don't bother with the pseudoscience peddled out by the denial camp because they are too busy getting on with the job.
A better approach for you would be to research how many of the deniers arguments have managed to be published in peer reviewed respected scientific journals? NONE.
Some deniers will tell you that this is because of some sort of scince community/governmnet conspiracy to hide the truth but the fact is, scientific journals publish arguments for and against a great many issues all of the time and it can be quite entertaining to track the arguments between particular scientists over time in the same journal, so to suggest some sort of bias on the part of journal reviewers is absurd. It just doesn't happen and any journal found to be scientifically or politically biased would soon find itself rejected by the greater scientific community and its reviewers shunned. Why then are there no published articles from the denier camp? It is because they are rejected by the reviewers on the basis of shoddy statistics, shoddy methodology or unscientific approaches.
