Job-killing proposals, warming fears, and unreliable data

National survey of NWS surface stations

A survey of National Weather Service weather stations finds that
most are improperly sited, yielding higher-than-proper
temperature readings.

As the country reels from the economic down-turn and officials cautiously hope for a recovery to begin by the end of this year, some Congressional leaders are calling for a “green recovery.” But Spain, which leads the world in creating green jobs, has found that for every green job created, 2.2 jobs are lost.

Now comes a memo from the Office of Management and Budget to Environmental Protection Agency saying, “Making the decision to regulate CO2 under the [Clean Air Act] for the first time is likely to have serious economic consequences for regulated entities throughout the U.S. economy, including small businesses and small communities.”

But, what would you think if you learned that the most reliable database in the world on which fears of man made global warming–the rationale for such a massive tax–are based was fundamentally unreliable? That almost 9 out of 10 measuring stations failed to meet basic criteria for long-term comparable data?

You’d probably think the fears weren’t well grounded–and neither was the tax.

That’s precisely the case with American temperature monitoring stations. They’re supposed to constitute the world’s most reliable set of stations, but 89% fail to meet the National Weather Service’s siting requirements . They’re exposed to all sorts of nearby point sources of heat that have increased over time, making their long-term records show a false upward trend.

As this map and its key show, the result is near-universal higher-than-proper temperature readings at stations around the country. (You can see stations in particular states here.)

A study of the significance of these and similar findings for stations around the world led two experts to conclude that estimates of warming from 1980 to 2002 were double what they should have been. Satellite records confirm this study’s results and show significant global cooling for the last seven years.

Are these good grounds to adopt expensive cap-and-trade?
