Paul C. (“Chip”) Knappenberger is the Assistant Director  of the “Center for the Study of Science” at the Cato Institute . Knappenberger works alongisde the Center's Director , fellow climate change denier Patrick J. Michaels . , 
Chip Knappenberger is the former Administrator of the World Climate Report , a blog published by New Hope Environmental Services , “an advocacy science consulting firm” run by global warming skeptic, Patrick J.

Stance on Climate Change
“The fact of the matter is that there does exist a growing body of scientific evidence that the climate changes in the coming decades will be modest and proceed at a rate that will lie somewhere near the low end of the IPCC projected temperature range.” 
“[W]e conclude that future global warming will occur at a pace substantially lower than that upon which US federal and international actions to restrict greenhouse gas emissions are founded. It is high time to rethink those efforts.” 
“The atmospheric concentration of carbon dioxide (CO2) has recently reached a 'milestone' of 400 parts per million (ppm). In some circles, this announcement has been met with consternation and gnashing of teeth. The proper reaction is celebration.” 
“There is still a general lack of evidence that shows a statistically significant relationship between anthropogenic climate change and weather-related damage…” 
“…the warming that appears in the compiled temperature history of the state [Utah] may not be evidence of regional (or larger-scale) climate change, but instead may be caused by non-climatic influences on the local thermometers.” 
On June 28, 2016, the American Association for the Advancement of Science (AAAS) issued the letter and a press release introducing the letter, describing it as a partnership of 31 leading nonpartisan scientific societies “reaffirming the reality of human-caused climate change, noting that greenhouse gas emissions 'must be substantially reduced' to minimize negative impacts on the global economy, natural resources, and human health.” 
“Obviously folks should be free to deliver their opinions,” said Knappenberger. “That said, since many of these organizations publish some of the most respected scientific journals, it certainly calls into question the degree of objectivity to which new science pertaining to the issues addressed in the letter is treated with. This is a far greater concern.”

Following the release of a study suggesting “favourable conditions for additional Antarctic sea ice growth since 2000,” Chip Knappenberger said that it “should come as a surprise to no one that natural variability is playing a strong role in Antarctic sea ice extent trends (i.e., recent growth),” reports The Washington Times . 
“It is wrong to suggest that growth there suggests that global warming is not happening,” said Chip Knappenberger, representing the Cato Institute's Center for the Study of Science. “Mostly, we have merely brought it up to point out the fact that global warming alarmists were only telling part of the story by focusing on what was going on in the Arctic.”

Writing in The Hill, Chip Knappenberger suggests that President Obama should back out of the Paris Climate pledge : 
“Rather than pay the rest of the world to look the other way, the president should revise, or better yet, rescind that promise.And now is the time to do that, before the grand signing ceremony of the Paris Climate Agreement that is scheduled for April 22, Earth Day, at the UN’s New York headquarters. Putting our name on a promise that we know we can’t keep would be a disingenuous act, painting the Paris Agreement not as a serious undertaking, but as a global publicity stunt.”

Chip Knappenberger co-authored a “working paper” with Patrick J. Michaels at the Cato Institute. The paper (PDF) makes “The case for lukewarming — modest anthropogenic climate change in accordance with the lower end of expectations from mainstream science,” which Michaels and Knappenberger describe as “simple, straightforward, and compelling.” ,

According to Knappenberger's archived profile at MasterResource , he has authored or co-authored over 20 papers “appearing in the peer-reviewed scientific literature,” and others in scientific conference proceedings, professional journals, and the press. 
Many of his papers were co-authored with fellow skeptic Patrick J. Michaels , and published by the Cato Institute  a swell as other think tanks such as the Science and Public Policy Institute (SPPI ). Some of Knappenberger's scientific articles have been debunked by DeepClimate .
