Update 02/11/15: The problems with California's underground injection control program are far worse than originally reported. It has now been revealed that California regulators with DOGGR not only permitted hundreds of wastewater injection wells but also thousands more wells injecting fluids for “enhanced oil recovery” into aquifers protected under the federal Safe Drinking Water...read more

Alan Carlin is an economist. He has published numerous articles relating to the economics of climate change but he is not a climate scientist.
In March 2009 he authored a critical review of the EPA’s draft report on endangerment from greenhouse gases. His article invited controversy on June, 2009, when the conservative Competitive Enterprise Institute (CEI) claimed that the EPA had suppressed the report.
Carlin maintains a website for his business titled Carlin Economics and Science as well as a blog of the same name where he voices his skeptical views on climate science.
Stance on Climate Change
“There is very little empirical evidence for rising GHG levels as the primary cause for global warming. Ice core data suggests that CO2 levels follow temperatures rather than the other way around. In fact, the all-important scientific tests of this hypothesis show that increases in GHG levels are not a significant cause of warming…” 
- “The Obama Administration has made many efforts to support its climate religion (climatism). Since this viewpoint has no basis in the scientific method, it is not science and would seem best characterized as religion.”

Appeared on the Glenn Beck Show where he contended that while U.N. Climate models anticipated an increase in global temperatures, actual temperatures had supposedly decreased between 2002 to 2008. 
In June 2009, the Competitive Enterprise Institute (CEI) and Senator James Inhofe claimed that the EPA had suppressed a report authored by Alan Carlin, that cast doubt on the existence of global warming and the need to regulate CO2 emissions.
Senator Inhofe wrote a letter to the EPA Administrator Lisa Jackson and called for a congressional investigation of the so-called “suppression.” 
The EPA Press Secretary Adora Andy responded, saying “Claims that this individual’s opinions were not considered or studied are entirely false… . The individual in question is not a scientist and was not part of the working group dealing with this issue. Nevertheless the document he submitted was reviewed by his peers and agency scientists, and information from that report was submitted by his manager to those responsible for developing the proposed endangerment finding.” In an e-mail response, Andy also said that “There was no predetermined position on endangerment, and Dr. Carlin’s work was not suppressed.” 
Carlin's report was also posted on the websites of the Heartland Institute, the Competitive Enterprise Institute, and several other think tanks.
In an interview, Carlin acknowledged that his report was not fully or cleanly sourced,  blaming a short deadline. He also admitted that there had been no restriction on his contact with the media. There has also been a question whether sections of Carlin's report were lifted from other sources without proper attribution.

A full list of Carlin's publications is available at his website.
Carlin states that is “the author or co-author of five published papers on climate change or energy pricing” but these papers appear to primarily address economic aspects of climate change.
