Michael Shermer, publisher of Skeptic Magazine

In 2001, Shermer hosted a Skeptics Society debate on global warming, prompted by Lomborg’s Skeptical Environmentalist. He sided, predictably, with the skeptics. Then he looked at the science, and in 2006 reached a “flipping point,” acknowledging the “overwhelming evidence for anthropogenic global warming.”
Before quote: “Scientists like Bjorn Lomborg in The Skeptical Environmentalist have, in my opinion, properly nailed environmental extremists for these exaggerated scenarios.” (2008, referring to 2001)
After quote: “Because of the complexity of the problem, environmental skepticism was once tenable. No longer. It is time to flip from skepticism to activism.” (2006)

Michael Hanlon, British science journalist
Hanlon, science editor for The Daily Mail, was a self-professed skeptic on climate change until a recent trip to Greenland, where he witnessed the accelerated disintegration of the country’s massive ice sheet. A few days on the melting ice floes, he says, “is certainly enough to blow a few skeptical cobwebs away.”
Before quote:Global warming, indeed much of environmentalism, has become a new religion. Like the old religions, environmentalism preaches much good sense, is well meaning, but has a worrying lack of logic at its core.” (2000)
After quote: “I have long been something of a climate-change sceptic, but my views in recent years have shifted. For me, the most convincing evidence that something worrying is going on lies right here in the Arctic.” (2010)
