Scientists rebut Obama Administration’s “National Climate Assessment”

Yes, that’s right … scientists.  Here’s their opening.  As you’ll see, they don’t mince words nor do they show much respect for the nonsense spouted in the NCA or those who produced it.  And I don’t blame them:

The National Climate Assessment – 2014 (NCA) is a masterpiece of marketing that shows for the first time the full capabilities of the Obama Administration to spin a scientific topic as they see fit, without regard to the underlying facts. With hundreds of pages written by hundreds of captive scientists and marketing specialists, the administration presents their case for extreme climate alarm.

As independent scientists, we know that apparent evidence of “Climate Change,”however scary, is not proof of anything. Science derives its objectivity from robust logic and honest evidence repeatedly tested by all knowledgeable scientists, not just those paid to support the administration’s version of “Global Warming,” “Climate Change,” “Climate Disruption,” or whatever their marketing specialists call it today.

We are asked to believe that humans are drastically changing the earth’s climate by burning fossil fuels. The problem with their theory is very simple:

It is NOT true.

Here we address the administration’s basic thesis and the essential evidence that they claim support extreme concern.  The theory of ‘Catastrophic Anthropogenic Global Warming’ (CAGW) is based on a string of inferences that begins with the assumptions that carbon dioxide is a ‘greenhouse gas’ and that we are slowly driving up the atmospheric concentration by burning fossil fuels. It is therefore claimed as self-evident that the Global Average Surface Temperature (GAST) has already risen significantly and will continue to do so.

Higher GAST is then presumed to lead to all sorts of negative consequences, especially Extreme Weather. They promote their ‘Climate Models’ as a reliable way to predict the future climate. But these models dramatically fail basic verification tests. Nowhere do they admit to these well-known failures. Instead, we are led to believe that their climate models are close to perfection.

This document is structured around a “fact-check,” where we quote a number of the government’s key claims in the NCA and show each to be invalid. The first three claims involve their three crucial scientific arguments (Three Lines of Evidence or 3 LoE), which, if valid, would satisfy a necessary, but not sufficient, condition for making their case. But each is easily shown to be false; and because each is crucial, their entire theory collapses. That means that all of the overblown “Climate Disruption” evidence that they mention, whether true or not, cannot be tied back to man’s burning of fossil fuels. Hence, efforts to reduce or eliminate Extreme Weather by reducing the burning of fossil fuels are completely nonsensical.

They then present a point by point rebuttal of the “3 LoE”, pointing to evidence that shows them to be demonstrably false.  And, as they point out, since those 3 LoE are the foundation of the CAGW theory, the theory collapses.
