From this article in the Daily Mail Online we get some new CO2 Insanity.
First, remember the “warmers” have been screaming about CO2 causing global warming for how long? The moaning and whining about emissions from cars, boats, trains, and PLANES.
Now all of a sudden no planes causes warming? Read on.
Seems no matter what happens, where it happens, or when it happens it causes global warming, or is caused by global warming.
Makes you want to scream.
Temperatures in Europe could rise as a result of planes being grounded across the continent, according to research.
A study conducted after commercial flights were grounded for three days following the September 11 terror attacks found the average daily temperature range in the U.S. rose markedly – exceeding the three-day periods before and after by 1.8c.
Scientists claimed this showed that clouds formed by the water vapour in the exhaust from jet planes have a small but significant effect on daily temperatures.
Ugh, so CO2 bad, water vapor good? Here’s what they claim is proof.
They matched the weather over those three days with similar weather in September over that period, and found that the difference in daily high and nightly low temperatures in the absence of planes’ contrails was more than 1c greater.
So 3 days is long enough to prove this? It couldn’t have been coincidence the weather changed could it? What data did they match? Did they cherry-pick something from the past that prove their point? Another case of making the data fit your desired result?
Meteorologists also warned however that volcanic ash could also decrease the temperature, by blowing immense amounts of material into the sky.
Bureau of Meteorology Aerosol Research Manager Jim Haywood said it was likely that Britons would see increased temperatures as a result of planes being grounded.
But he said that could be cancelled out by the volcanic ash, which in effect can act as contrails by reducing the temperature.
Based upon all this I’d have to question how they’ll be able to prove anything whatsoever. We claim warming from no jets flying, yet this warming could be cancelled by ash. So if one negates the other, then perhaps nothing will happen?
I’ll put out a sequel when they publicize their study. That should be interesting.
