Critique of the Head of the IPCC

Here is a detailed accounting of the misrepresentations by Dr. Rajendra Pachauri, chairman of the IPCC, in a talk he gave at the Copenhagen meeting. This list of indictments was prepared by Christopher Monckton. The following is taken from a posting on Anthony Watts' Watts Up With That? blog:
Science is not a belief system. But here is what Pachauri invited the audience in Copenhagen to believe.

1. Pachauri asked us to believe that the IPCC’s documents were “peer-reviewed”. Then he revealed the truth by saying that it was the authors of the IPCC’s climate assessments who decided whether the reviewers’ comments were acceptable. That – whatever else it is – is not peer review.

2. Pachauri said that greenhouse gases had increased by 70% between 1970 and 2004. This figure was simply nonsense. I have seen this technique used time and again by climate liars. They insert an outrageous statement early in their presentations, see whether anyone reacts and, if no one reacts, they know they will get away with the rest of the lies. I did my best not to react. I wanted to hear, and write down, the rest of the lies.

3. Next came the bogus graph, which is featured three times, large and in full color, in the IPCC’s 2007 climate assessment report. The graph is bogus not only because it relies on the made-up data from the Climate Research Unit at the University of East Anglia but also because it is overlain by four separate trend-lines, each with a start-date carefully selected to give the entirely false impression that the rate of warming over the past 150 years has itself been accelerating, especially between 1975 and 1998. The truth, however – neatly obscured by an ingenious rescaling of the graph and the superimposition of the four bogus trend lines on it – is that from 1860-1880 and again from 1910-1940 the warming rate was exactly the same as the warming rate from 1975-1998.


4. Pachauri said that there had been an “acceleration” in sea-level rise from 1993. He did not say, however, that in 1993 the method of measuring sea-level rise had switched from tide-gages to satellite altimetry against a reference geoid. The apparent increase in the rate of sea-level rise is purely an artefact of this change in the method of measurement.

5. Pachauri said that Arctic temperatures would rise twice as fast as global temperatures over the next 100 years. However, he failed to point out that the Arctic was actually 1-2 Celsius degrees warmer than the present in the 1930s and early 1940s. It has become substantially cooler than it was then.

6. Pachauri said the frequency of heavy rainfall had increased. The evidence for this proposition is largely anecdotal. Since there has been no statistically-significant “global warming” for 15 years, there is no reason to suppose that any increased rainfall in recent years is attributable to “global warming”.

7. Pachauri said that the proportion of tropical cyclones that are high-intensity storms has increased in the past three decades. However, he was very careful not to point out that the total number of intense tropical cyclones has actually fallen sharply throughout the period.

8. Pachauri said that the activity of intense Atlantic hurricanes had increased since 1970. This is simply not true, but it appears to be true if – as one very bad scientific paper in 2006 did – one takes the data back only as far as that year. Take the data over the whole century, as one should, and no trend whatsoever is evident. Here, Pachauri is again using the same statistical dodge he used with the UN’s bogus “warming-is-getting-worse” graph: he is choosing a short run of data and picking his start-date with care so as falsely to show a trend that, over a longer period, is not significant.

9. Pachauri said small islands like the Maldives were vulnerable to sea-level rise. Not if they’re made of coral, which is more than capable of outgrowing any sea-level rise. Besides, as Professor Morner has established, sea level in the Maldives is no higher now than it was 1250 years ago, and has not risen for half a century.

10. Pachauri said that if the ice-sheets of Greenland or West Antarctica were to melt there would be “meters of sea-level rise”. Yes, but his own climate panel has said that that could not happen for thousands of years, and only then if global mean surface temperatures stayed at least 2 C (3.5 F) warmer than today’s.

11. Pachauri said that if temperatures rose 2 C (3.5 F) 20-30% of all species would become extinct. This, too, is simply nonsense. For most of the past 600 million years, global temperatures have been 7 C (13.5 F) warmer than today, and yet here we all are. One has only to look at the number of species living in the tropics and the number living at the Poles to work out that warmer weather will if anything increase the number and diversity of species on the planet. There is no scientific basis whatsoever for Pachauri’s assertion about mass extinctions. It is simply made up.

12. Pachauri said that “global warming” would mean “lower quantities of water”. Not so. It would mean larger quantities of water vapor in the atmosphere, hence more rain. This is long-settled science – but, then, Pachauri is a railroad engineer.

13. Pachauri said that by 2100 100 million people would be displaced by rising sea levels. Now, where did we hear that figure before? Ah, yes, from the ludicrous Al Gore and his sidekick Bob Corell. There is no truth in it at all. Pachauri said he was presenting the results of the IPCC’s fourth assessment report. It is quite plain: the maximum possible rate of sea-level rise is put at just 2 ft, with a best estimate of 1 ft 5 in. Sea level is actually rising at around 1 ft/century. That is all.

14. Pachauri said that he had seen for himself the damage done in Bangladesh by sea-level rise. Just one problem with that. There has been no sea-level rise in Bangladesh. At all. In fact, according to Professor Moerner, who visited it recently and was the only scientist on the trip to calibrate his GPS altimeter properly by taking readings at two elevations at least 10 meters apart, sea level in Bangladesh has actually fallen a little, which is why satellite images show 70,000 sq. km more land area there than 30 years ago. Pachauri may well have seen some coastal erosion: but that was caused by the imprudent removal of nine-tenths of the mangroves in the Sunderban archipelago to make way for shrimp-farms.

15. Pachauri said we could not afford to delay reducing carbon emissions even by a year, or disaster would result. So here’s the math. There are 388 ppmv of CO2 in the air today, rising at 2 ppmv/year over the past decade. So an extra year with no action at all would warm the world by just 4.7 ln(390/388) = 0.024 C, or less than a twentieth of a Fahrenheit degree. And only that much on the assumption that the UN’s sixfold exaggeration of CO2’s true warming potential is accurate, which it is not. Either way, we can afford to wait a couple of decades to see whether anything like the rate of warming predicted by the UN’s climate panel actually occurs.

16. Pachauri said that the cost of mitigating carbon emissions would be less than 3% of gross domestic product by 2030. The only economist who thinks that is Lord Stern, whose laughable report on the economics of climate change, produced for the British Government, used a near-zero discount rate so as artificially to depress the true cost of trying to mitigate “global warming”. To reduce “global warming” to nothing, one must close down the entire global economy. Any lesser reduction is a simple fraction of the entire economy. So cutting back, say, 50% of carbon emissions by 2030, which is what various extremist groups here are advocating, would cost around 50% of GDP, not 3%.

17. Pachauri said that solar and wind power provided more jobs per $1 million invested than coal. Maybe they do, but that is a measure of their relative inefficiency. The correct policy would be to raise the standard of living of the poorest by letting them burn as much fossil fuels as they need to lift them from poverty. Anything else is organized cruelty.

18. Pachauri said we could all demonstrate our commitment to Saving The Planet by eating less meat. The Catholic Church has long extolled the virtues of mortification of the flesh: we generally ate fish on Fridays in the UK, until the European Common Fisheries Policy meant there were no more fish. But the notion that going vegan will make any measurable impact on global temperatures is simply fatuous.
