Have to admit, having read an AGW blog about COP-15 I could not avoid committing the sin of wasting time reading the Copenhagen Accord. And yes, there is an interesting and quite telling concept after all. It shows that no scientist, AGW believer or otherwise, has likely participated to the writing of the Accord, or has even been involved in reviewing any of it.
I am referring to a concept that is repeated twice:
(point 1) “recognizing the scientific view that the increase in global temperature should be below 2 degrees Celsius“
(point 2) “reduce global emissions so as to hold the increase in global temperature below 2 degrees Celsius“
In there, “the increase in global temperature” is referred in absolute terms. A much more scientific, logical and legal thing to write would have been
“the increase in global temperature due to anthropogenic interference“
To understand the absurdity of the Accord as it stands, imagine the world of 2050, with giant emission reductions already achieved, and powerful models showing that “anthropogenic interference” amounts to +1.7C. Still, if by pure misfortune natural variability sums up to +0.4C, the Copenhagen Accord says we have failed (despite having achieved the wildest dreams of the average 2009 greenie).
Imagine now another world of 2050, with no emission reduction at all and “anthropogenic interference” running at +3C. Still, if by pure stroke of luck natural variability sums up to -0.9C (eg a series of giant volcanic eruptions from 2045 onwards), the Copenhagen Accord says we have succeeded (despite having done nothing at all).
Sadly, all of that shows how silly is the idea that there is something good in the Accord because it has followed the lead of scientists. In truth, the Accord has made the IPCC irrelevant apart than as a confirming body for whatever the USA and China would like to see agreed upon regarding “climate change”.
