Editor’s note: Bradley’s op-ed appeared in the December 8th Washington Times under the title “Alarmists Cold-Shoulder Facts”)

Facts are awfully stubborn things. And global-warming alarmists—who generally don’t let facts get in the way of a good, agenda-driven argument—recently lost a key ally in the run-up to the U.N. global-warming pep rally opening today in Copenhagen. They lost actual data supporting their claims.

In defiant acts of desperation, many out-of-the-mainstream environmental alarmists quickly moved to plan B. Some cite the current El Niño—a natural climate variation—warning of “record” high temperatures just on the horizon.

Others continue to trumpet “studies” that paint terrifying environmental fairy tales if world governments do not immediately criminalize carbon, ban fossil fuels, and ration energy.

But these tactics are not new. Paul Ehrlich’s “population bomb” of the 1960s predicted food riots in the United States and around the world.…

The times are changing in the wake of Climategate. And more is to come as the polluted science embedded in the email exchanges gets reviewed by talented amateurs and pros alike on the blogosphere (see Climate Audit,  Roger Pielke Jr., and WattsUpWithThat, in particular).

Given time, the rethink will go mainstream. Scientists are truth seekers at heart, but an entrenched mainstream of climate scientists–so many of them friends and political allies–will need to be nudged out of their denialism.

Old voices are challenging their ‘mainstream’ colleagues, and new voices are coming forth. I have seen this clearly here in Houston (examples below), and I expect it is happening elsewhere.

Consider what Andy Revkin, the recently retired climate-change science writer at the New York Times, told the public editor at the Times regarding Climategate: “Our coverage, looked at in toto, has never bought the catastrophe conclusion and always aimed to examine the potential for both overstatement and understatement.”…

What a difference 12 months makes. Almost exactly one year ago, the popular, newly minted president, Barack Obama, was telling Congress that he wanted “legislation that places a market-based cap on carbon pollution and drives the production of more renewable energy in America.”

The Democrats, fully confident of their new president and their grip on both houses of Congress, were certain that they could pass yet another big energy bill that would finally push hydrocarbons off their pedestal and replace them with wind turbines, solar panels, and every other type of alternative energy.

An Unstimulated Economy

But a lot has happened since Obama delivered his first State of the Union address. The global economy has continued to show lackluster growth. And perhaps most important: unemployment rates in the U.S. remain stubbornly high and are expected to stay high for at least the next two years.…

In December 2009, economists Hector Pollitt and Chris Thoung of Cambridge Econometrics published a self-described “short” modeling exercise on an 80 percent greenhouse-gas emissions reduction by 2050 in the United Kingdom.[1] Pollitt and Thoung used the Energy-Environment-Economy Model of Europe (E3ME), which they observe has been “used for a variety of analyses including greenhouse-gas mitigation policies, incentives for industrial energy efficiency, and sustainable household consumption.”[2] The E3ME model covers 29 European countries and uses detailed data on 42 economic sectors, 41 categories of consumer goods, 12 types of fuel, and 14 emissions, including the six major greenhouse gases.…
