Addressing the Washington Policymakers in Seattle, WA, Dr. Don Easterbrook said that shifting of the Pacific Decadal Oscillation (PDO) from its warm mode to its cool mode virtually assures global cooling for the next 25-30 years and means that the global warming of the past 30 years is over. The announcement by NASA that the (PDO) had shifted from its warm mode to its cool mode is right on schedule as predicted by past climate and PDO changes (Easterbrook, 2001, 2006, 2007) and is not an oddity superimposed upon and masking the predicted severe warming by the IPCC. This has significant implications for the future and indicates that the IPCC climate models were wrong in their prediction of global temperatures soaring 1F per decade for the rest of the century.

The cool water anomaly in the center of the image shows the lingering effect of the year-old La Nina. However, the much broader area of cooler-than-average water off the coast of North America from Alaska (top center) to the equator is a classic feature of the cool phase of the Pacific Decadal Oscillation (PDO). The cool waters wrap in a horseshoe shape around a core of warmer-than-average water. (In the warm phase, the pattern is reversed). Unlike El Nino and La Nina, which may occur every 3 to 7 years and last from 6 to 18 months, the PDO can remain in the same phase for 20 to 30 years.

As shown by the historic pattern of PDOs over the past century and by corresponding global warming and cooling, the pattern is part of ongoing warm/cool cycles that last 25-30 years. Each time the PDO mode has shifted from warm to cool or cool to warm, the global climate has changed accordingly.  In 1977, the PDO shifted from cool mode to warm mode and set off the global warming from 1977 to 1998, often referred to as the “Great Climate Shift.” The recent shift from PDO warm mode to cool mode is similar to the shift that occurred in the mid-1940’s and resulted in 30 years of global cooling. The global warming from ~1915 to ~1945 was also brought on by a mode shift in the PDO.  Every indication points continuation of the PDO patterns of the past century and global cooling for the next 30 years. Thus, the global warming the Earth has experienced since 1977 appears to be over!

As western nations step up pressure on India and China to curb the emission of greenhouse gases, Russian scientists reject the very idea that carbon dioxide may be responsible for global warming. Russian critics of the Kyoto Protocol, which calls for cuts in CO2 emissions, say that the theory underlying the pact lacks scientific basis. Under the Theory of Anthropogenic Global Warming, it is human-generated greenhouse gases, and mainly CO2, that cause climate change. “The Kyoto theorists have put the cart before the horse,” says renowned Russian geographer Andrei Kapitsa. “It is global warming that triggers higher levels of carbon dioxide in the atmosphere, not the other way round.”

Russian researchers made this discovery while studying ice cores recovered from the depth of 3.5 kilometres in Antarctica. Analysis of ancient ice and air bubbles trapped inside revealed the composition of the atmosphere and air temperature going back as far as 400,000 years. “We found that the level of CO2 had fluctuated greatly over the period but at any given time increases in air temperature preceded higher concentrations of CO2,” says academician Kapitsa, who worked in Antarctica for many years. Russian studies showed that throughout history, CO2 levels in the air rose 500 to 600 years after the climate warmed up. Therefore, higher concentrations of greenhouse gases registered today are the result, not the cause, of global warming.

The hypothesis of anthropogenic greenhouse gases was born out of computer modelling of climate changes. Russian scientists say climate models are inaccurate since scientific understanding of many natural climate factors is still poor and cannot be properly modelled. Oleg Sorokhtin of the Russian Academy of Sciences Institute of Ocean Studies, and many other Russian scientists maintain that global climate depends predominantly on natural factors, such as solar activity, precession (wobbling) of the Earth’s axis, changes in ocean currents, fluctuations in saltiness of ocean surface water, and some other factors, whereas industrial emissions do not play any significant role. Moreover, greater concentrations of CO2 are good for life on Earth, Dr. Sorokhtin argues, as they make for higher crop yields and faster regeneration of forests. “There were periods in the history of the Earth when CO2 levels were a million times higher than today, and life continued to evolve quite successfully,” agrees Vladimir Arutyunov of the Russian Academy of Sciences Institute of Chemical Physics.

"The value of this paper lies in its dispassionate but ruthlessly clear exposition - or, rather, expose - of the IPCC’s method of evaluating climate sensitivity.  The detailed arguments in this paper, and, indeed, in a large number of other scientific papers, point up extensive errors, including numerous projection errors of climate models, as well as misleading statements by the IPCC.  Consequently, there are no rational grounds for believing either the IPCC or any other claims of dangerous anthropogenic global warming.” - Comment on paper by Viscount Monckton.

Mathematical proof that there is no “climate crisis” appears in a major, peer-reviewed paper in Physics and Society, a learned journal of the 10,000-strong American Physical Society, SPPI reports. Christopher Monckton, who once advised Margaret Thatcher, demonstrates via 30 equations that computer models used by the UN’s climate panel, the IPCC, were pre-programmed with overstated values for the three variables whose product is “climate sensitivity” (temperature increase in response to greenhouse-gas increase), resulting in a 500-2000% overstatement of CO2’s effect on temperature.

Climate Sensitivity Reconsidered demonstrates that a doubling of the concentration of CO2 in the air compared with pre-industrial levels, expected later this century, will be likely to increase global mean surface temperature not by the 6F predicted by the IPCC but, harmlessly, by little more than 1F. Lord Monckton concludes “Perhaps real-world climate sensitivity is very much below the IPCC’s estimates. Perhaps, therefore, there is no “climate crisis” at all. The correct policy approach to a non-problem is to have the courage to do nothing.

Larry Gould, Professor of Physics at the University of Hartford and Chair (2004) of the New England Section of the American Physical Society (APS), has been studying climate-change science for four years.  He said: “I was impressed by an hour-long academic lecture which criticized claims about ‘global warming’ and explained the implications of the physics of radiative transfer for climate change.  I was pleased that the audience responded to the informative presentation with a prolonged, standing ovation. That is what happened when, at the invitation of the President of our University, Christopher Monckton lectured here in Hartford this spring. I am delighted that Physics and Society, an APS journal, has published his detailed paper refining and reporting his important and revealing results.”

NRC Canada’s FTP site which logs the daily 10.7 centimeter (2800 megahertz) radio flux from the sun just reported what appears to be a new record low in the observed data, 62.5 at 1700 UTC. The 10.7cm solar radio flux is an indicator of the sun’s activity. Here is a brief description of it from the National Geophysical Data Center: The sun emits radio energy with a slowly varying intensity. This radio flux, which originates from atmospheric layers high in the sun’s chromosphere and low in its corona, changes gradually from day-to-day, in response to the number of spot groups on the disk. Radio intensity levels consist of emission from three sources: from the undisturbed solar surface, from developing active regions, and from short-lived enhancements above the daily level.

On July 18 1996, the observed value of the 10 cm solar flux dropped to a low of 64.9. In many books it is stated that the 10 cm solar flux can not go below a value of 67. For example, the formulae given in the June 1996 edition of the IPS Solar Geophysical Summary show 67.0 as the minimum value. So how can we get a value of 64.9? The answer is quite interesting - it depends on the orbit of the earth! The earth’s orbit is not perfectly circular but is slightly elliptical. In July of each year we are a little further than average from the sun and so solar radiation, including the 10 cm flux, is very slightly weaker than average. So the 10cm flux will tend to be lower in July than, for example, December when the earth is closer to the sun than its average value. The combination of the extra distance to the sun and the solar minimum conditions have acted to produce this very low flux value. It is easy to correct for the earth-sun distance and, when this is done, a value of 67.0 for 1996 was obtained. This is the text book value!

Values of the 10 cm flux are often given in two forms - first as directly observed values and secondly as values corrected for the earth-sun distance variation. The last time that the observed 10cm flux was at a lower value was on July 26, 1964 when it stood at 64.8. The lowest value ever recorded was on July 02, 1954 with a value of 64.4.

As we’e seen from visual cues and lack of sunpots recently, it is obvious that the sun is in a deep minima. Expert forecasts that have called for the sun to be regularly active by now have been falsified by nature, and the question of the day is: how long before the sun becomes active again?

The fundamental point is that the total atmospheric warming arising as a result of the density of the atmosphere is a once and for all netting out of all the truly astronomic number of radiant energy/molecule encounters throughout the atmosphere. The only things that can change that resultant point of temperature equilibrium are changes in solar radiance coming in or changes in overall atmospheric density which affect the radiant energy going out. In the real world the most obvious and most common reason for a change in atmospheric density occurs naturally when the oceans are in warming mode and solar irradiation is high as during the period 1975 to 1998. The increased warmth allows the atmosphere to hold more water vapour so that total atmospheric density increases and the atmospheric greenhouse effect strengthens. This effect is far greater than any CO2 effect. When the atmosphere cools again water vapour content declines and the atmospheric greenhouse effect weakens. CO2 and other trace gases are far too small a proportion of the atmosphere to have any significant effect in comparison to the water vapour effect. Even the water vapour effect has never provoked any tipping point in the face of the primary solar/oceanic driver so CO2 could never do so.

The Greenhouse Effect is only a tiny part of the global temperature control mechanism. In addition there is The Hot Water Bottle Effect whereby the oceans release stored heat intermittently at variable rates depending on the average state of the various oceanic oscillations at any particular time. The current assumption that the oceanic oscillations are ‘just’ a mechanism for redistributing heat already available to the atmosphere must be wrong. The oceanic heat store should be regarded as an additional heat source that adds or subtracts the effect of earlier solar irradiance (or lack of it) to or from the present day effect of current solar irradiance.

The total heat store available in the oceans is so large that it is capable of rendering changes in any Greenhouse Effect an irrelevance for all practical purposes. Oceanic oscillations are sufficient to cancel out or enhance the effects of natural variations in solar irradiance or other forms of solar input to the heat budget of the Earth for variable periods of time. A range of a mere 4 Watts per square metre or less in Total Solar Irradiance is sufficient to explain changes in Earth’s atmospheric temperature for the past 400 years. Outside that narrow band of apparent solar normality we would have more to worry about than any Greenhouse Effect.

The atmospheric greenhouse effect is a flea on the back of an oceanic elephant and the influence of CO2 but a microbe on the back of the flea and the influence of anthropogenic CO2 but a molecule on the back of the microbe. Read more here.
