I try not to play favorites between Republicans and Democrats when it comes to supporting or undermining the ideal of what Ludwig von Mises called the free and prosperous commonwealth. To this end, I have criticized Gov. Perry for his unfortunate windpower positions in Texas (see here and here), and I will do so again to the extent he buys into a government role in “green energy.”

Dessler Weighs In

A current spat is ongoing between Texas A&M climatologist Andrew Dessler and Perry, a front-runner for the Republican nomination for president of the United States, over global warming science and policy.

Dr. Dessler has written two opinion-page editorials published by the Houston Chronicle in recent months (July 10th and September 2nd) arguing that the science is settled in favor of climate alarm, meriting proactive public policy.…

On March 7th, the Houston Chronicle published an editorial by two Texas A&M climate scientists, Andrew Dessler and Gerald North (et al.):  “On Global Warming, the Science is Solid.” The op-ed argued that Climategate was a mere distraction and that climate science was settled in favor of alarm–both points being intended to challenge the State of Texas’s Petition for Rehearing to the U.S. Environmental Protection Agency’s endangerment finding, which was based on a belief of “settled science.”

A week later, a response/defense followed in the Chronicle, written by Texas Attorney General Greg Abbott: “State Suing for Responsible Scientific Conclusions.”…

Governor, have an aide challenge Andrew Dessler to set up a Texas-sized climate debate against his able adversaries. This should settle things by getting the mad Professor to either put up or shut up.

Dear Governor:

In a recent op-ed in the Houston Chronicle, Texas A&M climate scientist Andrew Dessler has once again challenged you to host him and his fellow alarmists to “educate” you on what he calls the “existential threat” of man-made climate change, as well as on the merits of the Green New Deal. He has been seeking an audience with you for some time (see here), as he did prior with Rick Perry (here).

Don’t bother. This emotional, angry, highly political Professor is an outlier. He refuses to debate the uncertainty monster of global climate change, choosing to alarm his audience.…

“Personal character matters for scientific transparency and honesty. Andrew Dessler does not pass the temperament test in a field of unsettled causality and ambiguous data.”

The intellectual case for CO2/climate optimism in place of doomism and despair is straightforward. As neatly summarized by Steven Koonin (a ‘climate flat earther‘ to Andrew Dessler) in the Wall Street Journal:

• Elevated carbon-dioxide levels enhance plant growth, contributing to global greening and increased agricultural productivity.
• Complex climate models provide limited guidance on the climate’s response to rising carbon-dioxide levels. Overly sensitive models, often using extreme scenarios, have exaggerated future warming projections and consequences.
• Data aggregated over the continental U.S. show no significant longterm trends in most extreme weather events. Claims of more frequent or intense hurricanes, tornadoes, floods, and dryness in America aren’t supported by historical records.
