The story starts, as is the case in so many states, with Gov. Mike Beebe's (video link) creation of the Governor's Commission on Global Warming. In most other states where they've been developed, these panels have been fashioned purely by executive fiat. Arkansas's GCGW was authorized also by a law (PDF) to study potential impacts of global warming and ways to mitigate greenhouse gas emissions (the presumed evil behind global temperature uptick). But the GCGW was also given the mandate to "study the scientific data, literature, and research on global warming to determine whether global warming is an immediate threat to the citizens in the State of Arkansas…."
Turns out this area of "study" was only allowed to go so far. As is the standard when the Center for Climate Strategies is granted management control of a state's climate commission (approaching two dozen so far), the prerequisite for CCS to take the job is that no debate of the climate science is allowed. Like the intolerant Al Gore, CCS cannot suffer dissent, flat-earthers, or moonwalk-deniers.
Needless to say, the likelihood that global warming would cause the Arkansas River to flood the William J. Clinton Presidential Library -- or other climate-driven Razorback State catastrophe could-be's -- was never discussed. Instead doom was presumed (PDF) should greenhouse gases continue unabated.
