Four Reasons Why Carbon Dioxide is Not Driving Global Warming

By

“There has not been a public debate about the causes of global warming and most of the public and our decision makers are not aware of the most basic salient facts:

1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.

Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most. The signature of an increased greenhouse effect is a hot spot about 10km up in the atmosphere over the tropics. We have been measuring the atmosphere for decades using radiosondes: weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. They show no hot spot. Whatsoever…

2. There is no evidence to support the idea that carbon emissions cause significant global warming. None. There is plenty of evidence that global warming has occurred, and theory suggests that carbon emissions should raise temperatures (though by how much is hotly disputed) but there are no observations by anyone that implicate carbon emissions as a significant cause of the recent global warming.

3. The satellites that measure the world’s temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6C in the past year (to the temperature of 1980). Land-based temperature readings are corrupted by the “urban heat island” effect: urban areas encroaching on thermometer stations warm the micro-climate around the thermometer, due to vegetation changes, concrete, cars, houses. Satellite data is the only temperature data we can trust, but it only goes back to 1979. NASA reports only land-based data, and reports a modest warming trend and recent cooling. The other three global temperature records use a mix of satellite and land measurements, or satellite only, and they all show no warming since 2001 and a recent cooling.

4. The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect.

None of these points are controversial. The alarmist scientists agree with them, though they would dispute their relevance.”

American Physical Society Retreats to the Consensus on Global Warming

By

Earlier in the week I received a note from Jan Pompe suggesting I might be interested in the editorial of the most recent issue of the journal of the American Physical Society. It included comment that:

“There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution. Since the correctness or fallacy of that conclusion has immense implications for public policy and for the future of the biosphere, we thought it appropriate to present a debate within the pages of P&S concerning that conclusion.”

A first contribution was by well known climate change skeptic Christopher Monckton. A link and some comment was posted at this blog to the article entiled Climate Sensitivity Reconsidered.

I was hopeful that at last maybe there would now be some opportunity for real debate and discussion amongst a mainstream community with some understanding of the relevant science. But just tonight I was copied the following letter from Christopher Monckton to the President of the society at Stanford University complaining that his paper is now prefaced with a warning …

“The editors of Physics and Society, a newsletter of the American Physical Society, invited me to submit a paper for their July 2008 edition explaining why I considered that the warming that might be expected from anthropogenic enrichment of the atmosphere with carbon dioxide might be significantly less than the IPCC imagines.

I very much appreciated this courteous offer, and submitted a paper. The commissioning editor referred it to his colleague, who subjected it to a thorough and competent scientific review. I was delighted to accede to
all of the reviewer’s requests for revision (see the attached reconciliation sheet). Most revisions were intended to clarify for physicists who were not climatologists the method by which the IPCC evaluates climate sensitivity – a method which the IPCC does not itself clearly or fully explain. The paper was duly published, immediately
after a paper by other authors setting out the IPCC’s viewpoint. Some days later, however, without my knowledge or consent, the following appeared, in red, above the text of my paper as published on the website of Physics and Society:

“The following article has not undergone any scientific peer review. Its conclusions are in disagreement with the overwhelming opinion of the world scientific community. The Council of the American Physical Society
disagrees with this article’s conclusions.”

This seems discourteous. I had been invited to submit the paper; I had submitted it; an eminent Professor of Physics had then scientifically reviewed it in meticulous detail; I had revised it at all points requested, and in the manner requested; the editors had accepted and published the reviewed and revised draft (some 3000 words longer than
the original) and I had expended considerable labor, without having been offered or having requested any honorarium.

Please either remove the offending red-flag text at once or let me have the name and qualifications of the member of the Council or advisor to it who considered my paper before the Council ordered the offending text to be posted above my paper; a copy of this rapporteur’s findings and ratio decidendi; the date of the Council meeting at which the findings were presented; a copy of the minutes of the discussion; and a copy of the text of the Council’s decision, together with the names of those present at the meeting. If the Council has not scientifically evaluated or formally considered my paper, may I ask with what credible scientific justification, and on whose authority, the offending text asserts primo, that the paper had not been scientifically reviewed when it had; secundo, that its conclusions disagree with what is said (on no evidence) to be the “overwhelming opinion of the world scientific community”; and, tertio, that “The Council of the American Physical Society disagrees with this article’s conclusions”? Which of my conclusions does the Council disagree with, and on what scientific grounds (if any)?

Having regard to the circumstances, surely the Council owes me an apology?

Yours truly,
THE VISCOUNT MONCKTON OF BRENCHLEY.”

The Society should not only apologize to Christopher Monckton, it should remove the “warning” and reread its editorial.
