The Arbitrary Diktats of Generalissimo Obama

August 16, 2013

Dan may think this isn’t a joke, but, from another perspective, it is: a big honking joke on us.

International Liberty

There’s an old joke that the definition of quandary is when your mother-in-law drives off a cliff in your new car.

But since I’m not married, I can’t use that joke.

Besides, I’m a policy wonk, so the type of quandary that catches my attention is when the Obama Administration delays big parts of Obamacare (hooray!), but does so by cavalierly deciding to disregard the law (boo!).

Unfortunately, this isn’t a joke.

I wrote about this topic last month and asserted that one of “the defining characteristics of a civilized government is adherence to the rule of law.”

Why is this important? Here’s some of George Will’s analysis of how Obama is subverting the law.

President Obama’s increasingly grandiose claims for presidential power are inversely proportional to his shriveling presidency. …at last week’s news conference he offered inconvenience as a justification for illegality. …Serving as props in the scripted charade…

Oh Mann! Paper demonstrates that tree-ring proxy temperature data is ‘seriously compromised’

August 16, 2013

This is potentially a huge blow to the Cult of Anthropogenic Global Warming. Tree-rings have been used as proxies, in lieu of having direct instrumental measurements of temperature change in ages past. They’ve been foundational to the assertion of a connection between CO2 levels and warming, and thus as evidence that Man has accelerated that warming. And if it turns out the tree-ring analysis was severely biased…. Well, Al Gore won’t be pleased at all.

Watts Up With That?

Michael Mann won’t be happy about this.

A new paper now in open review in the journal Climate of the Past suggests that “modern sample bias “has “seriously compromised” tree-ring temperature reconstructions, producing an “artificial positive signal [e.g. ‘hockey stick’] in the final chronology.”

Basically, older trees grow slower, and that mimics the temperature signal paleo researchers like Mann look for. Unless you correct for this issue, you end up with a false temperature signal, like a hockey stick in modern times. Separating a valid temperature signal from the natural growth pattern of the tree becomes a larger challenge with this correction.

Here is a relevant excerpt:

Much of the work in dendrochronology, and dendroclimatology in particular, relies on accurate, unbiased reconstructions of tree growth long into the past. As a result, a great deal of effort has been put into trying to isolate important trends and identify potential 5…
