Flying

Last night on the telly there was a programme about whether we should all stop flying around the world in all these jet planes.

It was outraaaaaaaageous!!

OK, first part about the eeeeeevil airplanes and the eeeeeeeeevil people who want to fly in them.
Next, shots of Venice "sinking" due to rising water levels.

HANG ON! Erm, excuse me, what exactly is the link here??

Venice is sinking because of the airplanes? Riiiiiiiiight!



What bugged me the most was the hidden implied certain link between the planes and the water levels.

So, you take two variables that seem to have a correlation (and, boy oh boy, you want them to...) and in your mind you draw a lovely straight line graph to prove it. This is a classic error we see so many times. It's rarely as simple as this!! Just because two variables are varying as though they were directly linked it doesn't mean they definitely are.

Good point.

It reminds me of a site which is well worth a visit too: http://indexed.blogspot.com/

Oh yeah - as a Southamptonite I noticed the ads posted up by FlyBe recently.. amazing cheap prices to lovely destinations. It was the small print that drew my attention though:

"* flying the environmentally friendly Bombadier Q400 aircraft"

Environmentally friendly? In what way is an aircraft that is burning fuel 'friendly'. I thought at the time that if it were a war and we were only responsible for killing 25% of the people that the other people fighting were doing that we would be waging a friendly war?
