There are scientists who are not paid by anybody who believe climate change does not exist, though the speaker immediately added that "plenty" was a bit of a stretch.

Judge as of 2007-09-28. The speaker himself withdrew 'plenty', so test only whether some scientists with no funding from interested parties believed climate change does not exist. True: credible evidence shows that in 2007 a number of credentialed scientists, with no documented industry funding, publicly denied that climate change was occurring (not merely its human cause). Mostly true: such scientists existed, but mostly disputed the human cause or the severity rather than whether change was happening at all. Mixed: there were very few such scientists, and their independence from funding is unclear. Mostly false: nearly all prominent sceptics had documented ties to fossil-fuel or advocacy funding, or none denied that change existed outright. False: there were no such scientists.

Set before the research began.

   “Gray says he’s received no money from energy companies, beyond reimbursing his expenses for traveling to a conference or two; in fact, he claims that funding for his own research has suffered as a result of his views.”

2. E2 The Skeptic Westword · 29 June 2006

   “Gray accepts that the earth has gotten warmer over the past century, particularly in the past three decades.”

3. E3 A Note on Skeptics and Contrarians Society of Environmental Journalists (SEJ) · 24 August 2008

   “There are a number of climate-change skeptics, less-often quoted perhaps than some more vocal ones discussed later, who have more substantial climate science research publications and who have accepted little or no fossil industry and advocacy group money.”

4. E4 Alternative Views on Climate Change | Council on Foreign Relations Council on Foreign Relations · 27 September 2007

   “Although alternative views of climate change often have been labeled denial--a few researchers say the world is cooling--most climate-change skeptics do concede the planet is warming.”

E3 (2008) says there were credentialed climate sceptics with substantial research records who had taken little or no money from the fossil-fuel industry or advocacy groups. E1 reports that the sceptic Gray said he had received no energy-company money beyond travel expenses. However, E2 shows that Gray accepted the earth had warmed. E4, dated the day before the claim, says that although a few researchers argued the world was cooling, most sceptics conceded that it was warming. So independent sceptics existed, but they mostly disputed the cause or severity of climate change, not whether it was happening at all.
