An open letter from The Viscount Monckton of Brenchley to Senator John McCain about Climate Science and Policy
From American Thinker, Oct 18, 2008
Some excerpted highlights include:
Sir, every one of the reasons that you have advanced for alarm and consequent panic action has been demonstrated to be hollow and without any scientific foundation or merit. Yet, if your proposal to close down three-fifths of the economy of the United States is to be justifiable, then not only the false scientific propositions but also the false policy propositions that you have advanced must be shown to be true.
A recent survey (Schulte, 2008) of 539 peer-reviewed scientific papers published since January 2004 and selected at random using the search term "global climate change" reveals that not a single paper provides any evidence whatsoever that "time is short" or that "the dangers are great". The notion of imminent, catastrophic climate change is a fiction that is almost wholly absent in the scientific literature. Indeed, the only papers that predict catastrophe are written by a tiny clique of closely-connected, extravagantly-funded, politically-biased scientists with unhealthily close political and financial connections to certain alarmist politicians in the party that you nominally oppose.
....there is no rational basis for your declared intention that your great nation should inflict upon her own working people and upon the starving masses of the Third World the extravagantly-pointless, climatically-irrelevant, strategically-fatal economic wounds that the arrogant advocates of atmospheric alarmism admit they aim to achieve
In 2001 the UN's climate panel made a maladroit and disfiguring attempt [IPCC, 2001] to heighten the baseless alarm that underlies all of its reports by denying that the Middle Ages were warmer than the present. However, three eminent statisticians working at the instigation of your own House of Representatives produced the definitive report [Wegman et al., 2005], confirming the peer-reviewed research of McIntyre & McKitrick (2003, 2005) establishing that the UN's graph had been doctored so as falsely to deny the reality of the mediaeval warm period, to whose existence hundreds of peer-reviewed papers from all parts of the globe attest.
At both Poles, it was warmer only half a century ago than it is today. For temperatures in the Arctic, see Soon et al. (2004). For the Antarctic, see Doran et al. (2002).
During the Maunder Minimum, a period of more than half a century ending in 1700 when there were no sunspots on the surface of our Sun, a Little Ice Age occurred all over the world (Hathaway, 2004). In 1700 there began a recovery in solar activity that has continued ever since, culminating in the 70-year Solar Grand Maximum that seems recently to have ended. During the Grand Maximum, the Sun was more active, and for longer, than during almost any previous similar period in the past 11,400 years (Solanki et al., 2005; and see Usoskin et al., 2003; and Hathaway, 2004). A symposium of the International Astronomical Union  concluded that it is the Sun that was chiefly responsible for the warming of the late 20th century.
From 1700-1998, temperature rose at a near-uniform rate of about 1 °F per century [Akasofu, 2008]. In 1998, "global warming" stopped, and it has not resumed since: indeed, in the past seven years, temperature has been falling at a rate equivalent to as much as 0.7 °F per decade [Hadley Center for Forecasting, 2008; US National Climatic Data Center, 2008].
The correct question, posed by Akasofu , is this: Since the world has been warming at a uniform rate in parallel with the recovery of solar activity during the 300 years following the Maunder Minimum, and since humankind could not have had any significant influence over global temperature until perhaps 50 years ago, if then, is there any evidence whatsoever that the observed anthropogenic increase in carbon dioxide concentration over the past half-century has had any appreciable influence, at all, on global temperature?
Despite rapidly-rising carbon dioxide concentrations, there has been no new record year for global temperature in the ten years since 1998; and, in the United States, there has been no new record year for national temperature since 1934 - a record set almost three-quarters of a century ago, and well before humankind could have had any significant influence on temperature.
As to your second statement, the "worst" greenhouse gas - the one which, through its sheer quantity in the atmosphere, accounts for two-thirds of the 100 Watts per square meter of greenhouse-gas radiative forcing reported by Kiehl & Trenberth (2007, op. cit.) - is water vapor. Carbon dioxide accounts for little more than a quarter.
Two-thirds of the carbon dioxide concentration in the atmosphere is naturally present
Let me summarize the irremediably shaky basis for the UN's alarmist case. It is not based on physical theory. It is not based on real-world observation. It is based on computer modeling, in which - astonishingly - the models are told at the outset the values for the very quantity (temperature response to increased carbon dioxide concentration) that they are expected to find.
.....would be even more absurd than trying to claim 90% confidence for a proposition that depends absolutely for its validity upon parameters that cannot be measured and can only be guessed: and a proposition that is demonstrated to be false with each successive year during which no further "global warming" takes place. It is regrettable that anyone should seek to make policy, as you have done, on such a manifestly unsound basis.
The "central facts" about "rising" sea levels are as follows.
Sea level has been rising since the end of the last Ice Age 10,000 years ago. It is 400 feet higher now than it was then. The rate of increase has averaged 4 feet per century. Yet in the 20th century, when we are told that "global warming" began to have a major impact on global temperature and hence on sea level, sea level rose by just 8 inches.
The oceans are not getting warmer (except in certain regions, such as the Antarctic Peninsula, where there is evidence of undersea volcanic activity).
Now a definitive study based on readings from 6000 bathythermographs, shows that the oceans have indeed been cooling since at least 2003, in line with the atmospheric cooling noted in the observed temperature record.
The facts about "reduced snowpack"
there has been no reduction in overall snow cover in the Northern Hemisphere in the 30 years since satellites were first able to measure its extent.
Your advisors needed to go no further than the Rutgers University Snow and Ice Lab, which has monitored snow cover in the Northern Hemisphere in the vital winter months for 30 years. During that time, there has been no trend in winter snow cover. There has been no decline at all, either in any individual winter month or at all. Indeed, new records for the extent of Northern-Hemisphere winter snow cover were established in 2001-2 and again in 2007-8, the winter immediately before your speech.
The facts about "receding glaciers"
.....more than 160,000 glaciers in the world [IPCC, 2001].
Professor Bhat reports that most of the glaciers have been receding at a uniform rate since 1880 at the latest. Some of them had begun receding even before this date.
Given that glacial recession began long before humankind could have had any appreciable effect on global temperature, and given that the rate of recession has remained uniform, on what basis can it be said, as you have implied, that it is anthropogenic "global warming" that is causing the glaciers to recede?
In the very cold winter of 2007/8, during which the biggest January-to-January fall in global temperatures since records began in 1880 was recorded, several glaciers in Greenland began to re-advance.
The facts about "melting polar ice sheets"
There are four great polar ice sheets: the East and West Antarctic ice sheets; the Greenland ice sheet; and the Arctic ice-cap.
The East Antarctic ice sheet is on a high plateau at high latitude. Since most of Antarctica has cooled over the past 50 years (Doran et al., 2002), so much so that environmental damage caused by cold has occurred in some of the Antarctic glens, there is no danger of this ice sheet disappearing, and there are no satellite images revealing that it has done so, is doing so, or is about to do so.
Greenland ice sheet increased by 2 inches per year - a total of 1 ft 8 in - during the decade 1993-2003.
It has long been settled science that a warmer climate would reduce the frequency and intensity of severe storms outside the tropics.
However, it is now known that warmer weather reduces the temperature differential between the Equator and the Poles; and that wind-shear tends to dampen the intensity of the worst hurricanes.
Two prominent dissenters - notably Emanual (2008) - have resiled in recent weeks from their previously-published opinions to the effect that the intensity of hurricanes might be expected to increase with warmer worldwide weather.
thirdly, for the past ten years there has been no "global warming", so that, even if there had been "a higher incidence of extreme-weather events", which there has not, "global warming" (whether natural or anthropogenic) cannot possibly have been the cause.
