Everyone swears the IPCC have proof, but still nothing from the AR5

The IPCC don’t have no evidence!

(All right, all right! Leave off with the double negative put-downs already!)

common arguments • interesting rebuttals • startling absence of proof

Reader:

Looking at the recent geological (let’s say prehistoric) record then the exogenous inputs (mainly from volcanism) seem to have been low relative to historic exogenous inputs (mainly from agricultural soil organic matter breakdown and fossil fuel burning), which means that the two eras are not comparable and so conclusions drawn from one cannot be applied to the other.

Yet the IPCC does exactly that. They rip an isolated fact from its primeval context and claim it applies today. But it flies in the face of copious evidence and asserts that the global mean surface temperature (GMST) is determined by only a single factor: the trace gas carbon dioxide. For instance, on p. 50, the AR5 Technical Summary harks back 52 million years to inform us: Continue Reading →

A “greenhouse gas” is one capable of absorbing infra-red (IR) radiation.

The most common atmospheric gases with such properties are water vapour and carbon dioxide (CO2). Water vapour is far more abundant with an average of 20,000 parts-per-million (ppm) in the atmosphere compared to just 395 ppm of CO2. Moreover water vapour is more effective as a greenhouse gas because it can absorb IR radiation over far more bands of the IR spectrum.

Therefore, if man-made CO2 causes dangerous global warming, (a dubious proposition anyway), then man-made water vapour is far more dangerous. Continue Reading →

Nobody really wants a new climate treaty

So, it’s official: the possibility of a replacement being hammered out for the Kyoto Treaty now appears remote.

It will be “physically impossible” to have a detailed deal to tackle climate change by this December’s summit in Copenhagen, UN Framework Convention on Climate Change (UNFCCC) Executive Secretary Yvo de Boer said on Wednesday in Bonn.

The “four tough nuts”, as he termed them, were proving extremely difficult to crack because, he said, the “delivery on four political essentials”, on which success in Copenhagen would depend, was turning out to be “impossible”. Continue Reading →

Shock! Horror! CO2 feeds us!

Written for TOOL Magazine, August 2008

Once upon a time, street-corner zealots shouting “the end is nigh” and warning us to abandon our sins did it for religious reasons. These days, zealots shout the same message with the same warning about sinning, but they do it for climatic reasons. Continue Reading →
