There's quite a good list at (of all places) Wikipedia. It seems reasonably complete and surprisingly free of the sort of politicized bias so often on display at La Wik. It's also very well organized, with separate sections for those who question the accuracy of the IPCC climate projections, those arguing that the current warming is a fundamentally natural process, those who think that the causes of the warming are unknown, and those who think that warming will have few negative consequences.
There is a list of deceased scientists as well - long time readers will remember Hal Lewis and his spectacular resignation letter to the president of the American Physical Society.
This is a quite interesting list, and potentially useful as well. The argument that most scientists support the "consensus view" is not only wrong, it's dumb. It's essentially saying "my scientist is red hot, your scientist ain't doodly-squat".
