Looking for proof in climate debate

In his letter, "Scientists do not agree on warming," Roger Willis speaks out against those who think "there is irrefutable evidence that humans are causing climate change." He states that there is "a ton of recent scientific counter-evidence."

I would appreciate it very much if Mr. Willis would share with us several examples of studies by independent, respected scientists who have researched and published their findings that humans are not the most significant cause of climate change.

I'm not asking for a ton of examples - just a few hundred pounds.
