Global cooling

From Brit Hume's "Grapevine" last night:
Tuesday we told you about several areas around the planet experiencing
record cold and snowpack — in the face of all the predictions of global
warming.

Now there is word that all four major global temperature tracking
outlets have released data showing that temperatures have dropped significantly
over the last year. California meteorologist Anthony Watts says the amount of
cooling ranges from 65-hundredths of a degree Centigrade to 75-hundreds of a
degree.

That is said to be a value large enough to erase nearly all the
global warming recorded over the past 100 years. It is reportedly the single
fastest temperature change ever recorded — up or down.

Some scientists contend the cooling is the result of reduced solar activity — which they say is a larger driver of climate change than man-made greenhouse gases.

I'm not a proponent of man-made global warming. However, a one year dip hardly indicates anything. Most scientifically trained individuals know that datasets can have anomalies and that you have to look at trends to make a solid analysis.

One thing I've always been very critical with global warming advocates is their tendency to use local systems or isolated incidents as "proof" of global warming. Yes, it's been a cold year. Yes, it's been uncharacteristically cold globally. What does it mean? Probably not much unless it reflects a new trend.

I think we should be studying the actual impact of CO2 on global temperatures. There is mounting evidence suggesting that global warming is not caused by CO2. Rather, it's simply a correlating piece of data and that CO2 may be a trailing indicator of warming. In other words, CO2 doesn't cause the Earth to heat up; the Earth heating up generates more CO2. Additionally, it’s important to remember that CO2 is actually a minor “green house gas” when compared to the giant, water vapor. Additionally, of the CO2 put into the atmosphere, man

However, I don't expect this political firestorm to be debated rationally. Global Warming is far too beneficial for political power consolidation to be dropped in the face of unsupportive data.

oops - missed one statement:

Of the CO2 in the air, man isn't the only contributor...
