Claims have recently surfaced in the blogosphere that an increasing number of scientists are warning of an imminent global cooling, some even going so far as to call it a "growing consensus". There are two major flaws in these blog articles, (i) there is no scientific basis for claims that the planet will begin to cool in the near future, and (ii) many of the listed scientists are not predicting global cooling.

Sounds like we have another denialist troll (or sock puppet?) on board.
Can't even manage to be creative enough to come up with something new...just the same old denialist retreads.

Joseph Fourier, in 1824, found that Earth's atmosphere kept the planet warmer than would be the case in a vacuum. Fourier recognized that the atmosphere transmitted visible light waves efficiently to the earth's surface. The earth then absorbed visible light and emitted infrared radiation in response, but the atmosphere did not transmit infrared efficiently, which therefore increased surface temperatures. He also suspected that human activities could influence climate, although he focused primarily on land use changes.
John Tyndall took Fourier's work one step further in 1859 when he investigated the absorption of infrared radiation in different gases. He found that water vapor, hydrocarbons like methane (CH4), and carbon dioxide (CO2) strongly block the radiation.
In 1896 a Swedish scientist, Svante Arrhenius... ...calculated that cutting CO2 in half would suffice to produce an ice age. He further calculated that a doubling of atmospheric CO2 would give a total warming of 5–6 degrees Celsius.

It's only been 30-ish years since James Hansen went public on the issue, barely enough to grok 'wandering jet stream'.

You are most welcome to continue to trying to educate me. But thus far, and until I see anything that persuades me otherwise, I am happy to err on the denier side of the fence until about 2020-25 when we will either be very cold and the IPCC will be forced to change its tune, or I will be obliged to accept that the orthodox position is the correct one.

I understand that ice core samples now tell us that movements in the change in both CO2 and temperature follow the change in atmospheric temperature. If one accepts that, then one must accept that CO2 doesn't cause much if any warming. But is that right? .
energy investor, Understand that the AGW/CC fanboys here at Peak Oil are an extreme fringe group.
The scientific consensus is clear. Building on two previous studies, a landmark 2013 peer-reviewed study evaluated 10,306 scientists to confirm that over 97 percent climate scientists agree, and over 97 percent of scientific articles find that global warming is real and largely caused by humans.
A more recent peer-reviewed paper examined existing studies on consensus in climate research, and concluded that the 97 percent estimate is robust.
This level of consensus is equivalent to the level of agreement among scientists that smoking causes cancer – a statement that very few people, if any, contest today.
And as to potential severity one need only know that GW is implicated in the biggest mass extinction event in the entire history of Earth
