Richard A. Keen
- Ph.D., Geography/Climatology, University of Colorado. 
Richard A. Keen is instructor emeritus  at the University of Colorado Department of Atmospheric and Oceanic Sciences (ATOC). Some sources have also described him as a “climatologist ,” and others as a “meteorologist.” , 
According to Keen , he has experience as a meteorologist in the army and has “done some climate modeling when I was younger and less wise.” He does not mention receiving any training as a climatologist. 
He is the author or co-author of numerous books including Skywatch West: The Complete Weather Guide and The Audubon Society Pocket Guide to Clouds and Storms.
Stance on Climate Change
“Half or more of the warming since 1995 may due to the lack of large volcanic eruptions… . The remaining climate change is presumably caused by other forces, such as solar variability, El Nino, Atlantic AMO warming in 1995, lower Albedo and maybe even a little greenhouse gas.” 
“Since the total direct impact of Carbon on climate is 0.2C, and US carbon production is no longer rising, controls such as Cap 'n Trade and Kyoto are ineffective solutions that will fail to solve a non-existent problem.” 
“”Earth has cooled since 1998 in defiance of the predictions by the UN-IPCC… . The global temperature for 2007 was the coldest in a decade and the coldest of the millennium … which is why 'global warming' is now called 'climate change.'”

Richard Keen was one of fourteen Amici , described as “well-qualified climate scientists,” who claimed that the “EPA's endangerment finding is not 'rational' and therefore arbitrary and capricious.”
“[T]he Earth's climate is not changing in an unusual or anomalous fashion. The EPA relied on instrumental data that were adjusted to exaggerate the increase in global temperatures.” 
Petitioners listed were:

Speaker at the Doctors for Disaster Preparedness  27th Annual Meeting in Denver, Colorado. His presentation was titled “Volcanoes, Stars, and Gases, oh My! What's changing our climate?”

Keen was a speaker at the Heartland Institute's 2009 International Conference on Climate Change (ICCC2). His talk was titled “Volcanoes and Climate Change Since 1980: A View from the Moon .” 
DeSmogBlog researched the funding behind Heartland's Second International Conference on Climate Change , and found that sponsor organizations had received over $47 million in funding from energy companies and right-wing foundations, with 78% of that total coming from Scaife Family foundations .

Keen's signature was appended to a Cato Institute advertisement  that criticizes comments made by President-Elect Barack Obama which had listed climate change as an urgent issue.
The ad states “We, the undersigned scientists, maintain that the case for alarm regarding climate change is grossly overstated. Surface temperature changes over the past century have been episodic and modest and there has been no net global warming for over a decade now… .Mr. President, your characterization of the scientific facts regarding climate change and the degree of certainty informing the scientific debate is simply incorrect.”

“Dr. Richard Keen's 'Global Warming Quiz '” was posted on Roger Pielke 's web blog and hosted at the skeptical ICECAP website (PDF) . The quiz's closing remark is “Enjoy the warm climate while it lasts, and please make enough CO2 to feed a tree.” 
According to some sources , Keen had committed “blatant cherry picking of historical data with a collection of historical examples of warm periods and extreme weather events” in his interpretation of the Science.
