Alert : Global Cooling Is Coming !!!

The Middle ground on the Global Weather Thang

From the article:
The redoubtable Andrew Revkin wrote in the New York Times on 1 January about the evolution of the debate over global warming into a more nuanced, sensible discussion. (Read it soon before it disappears from the public Web.) He or his headline writer labeled the voices between the previous extremes as a "new middle stance." But from my viewpoint the middle has always been there, annoyed with both Greenpeace and the Greening Earth Society. Carl Wunsch, quoted by Revkin, is a great example: "It seems worth a very large premium to insure ourselves against the most catastrophic scenarios. Denying the risk seems utterly stupid. Claiming we can calculate the probabilities with any degree of skill seems equally stupid."

Science Latest Research Erodes CO2's Role in Global Warming

Researchers on three different continents agree; CO2 is not the devil we once thought.

Last week I reported on a new study by the Belgium Royal Meteorological Institute that stated the effects of CO2 on world temperatures had been "grossly overstated". The RMI's conclusion is supported by a pair of recent papers, both of which severely downgrade the warming effect of carbon dioxide.
The first is by atmospheric scientist Stephen Schwartz, of Brookhaven National Labs. Entitled, "Heat Capacity, Time Constant, and Sensitivity of Earth's Climate System", the paper is based on more accurate estimates of feedback processes in the Earth's atmosphere. It concludes the IPCC estimate of 2 - 4.5C degrees warming (from the anticipated 1900-2100 doubling of CO2 levels) is much too high, and the actual figure should be closer to 1.1 degree.
The conclusion is very significant as we've already experienced some 0.7 degrees of that warming. That means over the next century, only an additional 0.4 degrees warming is expected. And after that, the warming effect will nearly vanish.
The reason why is CO2 only absorbs in a very narrow band of infrared. Climatologist Timothy Ball, who was not associated with this study, explains with an analogy: "The relationship between temperature and CO2 is like painting a window black to block sunlight. The first coat blocks most of the light. Second and third coats reduce very little more. Current CO2 levels are like the first coat of black paint."
The second study is by Chinese researchers Lin Zhen-Shan and Sun Xian. Using a technique called Empirical Mode Decomposition (EMD), they decoded temperature changes into three natural cycles-- 6-8 years, 20 years, and 60-years, along with a fourth signal, a non-periodic rising trend, which they associated with CO2-based warming. They found that the largest effect on temperature change was due to these natural cycles, and that the CO2-based trend could only be responsible for a maximum of 40% of the warming attributed to it.
Most astonishingly, they concluded that global cooling will result for at least the next two decades, as the longer cycles are now both in downward motion.
The factor all three of the above studies have in common? That CO2's role has been massively overstated. The political consequences of this are widespread-- is it worth spending trillions of dollars to reduce emissions of a gas that will have almost no effect over the next century, and essentially none at all after that?
