Al Gore calls for climate ‘mobilisation’ - Times Online

“We must mobilise our civilisation with the urgency and resolve that has previously been seen only when nations mobilised for war.”

Whilst Al dreams of leading his battalions into battle in the real world Dennis Ambler sends a link to an interesting article which shows how this:

IPPC1%20recoord.bmp

Average global temperatures from 1000 AD as shown in the First IPCC Assessment

“A global warming of larger size has almost certainly occurred at least once since the end of the last glaciation without any appreciable increase in greenhouse gases. Because we do not understand the reasons for these past warming events, it is not yet possible to attribute a specific proportion of the recent, smaller warming to an increase of greenhouse gases.”

And if you think it was better scientific knowledge I have a bridge for you to buy.....

I would be grateful if you could answer this question prompted by the plight of the penguins reported on BBC News today. Antarctica is warming up 5 times faster than the rest of the world, apparently. I understand ozone is a greenhouse gas which causes warming. The hole in the ozone layer over the Antarctic identified in the eighties is now shrinking thanks to PCB and fluorocarbon banning. Is there a connection with Antarctica's warming? I only ask.

Where do you get the "Antarctica is warming up 5 times faster than the rest of the world" from, Gallimaufry? If you go here (the alleged fount of all knowledge) and look at Figure SPM2 you will see that this is not the case:

Hi DocBud, Many thanks for your link. I got the 5 times from this

http://www.wwf.org.uk/news/n_0000004611.asp

and this

http://www.guardian.co.uk/environment/2007/dec/11/endangeredspecies.conservation

and a recent tv news item on penguins. It appears it's the "Antarctic Peninsula" that's warming faster. Statistics again!

But would a smaller hole in the ozone layer warm up Antarctica as there is more ozone around?
