News Flash, Queensland in financial trouble due to global warming, Victorians no longer need to travel North
The reality is it's all the graffiti artists (?) with their bleeding spray cans doing the damage, and Bob Carr who talks out his Asre thereby creating more methane.Stupidity kills. Absolute stupidity kills absolutely.

16th January 2006, 04:54 PM #62All this means is that you can't take our limited day by day impressions of weather over a hot summer and claim that global warming is a coming.... It may be, (and if I were a tundra dweller, I'd say ..."Bring it on!") but one hot day don't prove anything.
Although not fully settled, the current consensus from the official scientific communities on climate change is that recent warming is largely human-caused.
According to the Third Assessment Report of the IPCC, most of the observed warming over the last 50 years is 66% to 90% certain to have been due to radiative forcing from increases in greenhouse gas concentrations."I don't practice what I preach because I'm not the kind of person I'm preaching to."

God help me, I listen to ABC News Radio too much. Last week Australia's leading climatologist (He went to school for it and everything) was being interviewed. He told of his earlier reluctance to make climate predictions for too far in the future, as he didn't know what deus ex machina (my term) would appear to ruin the prediction.
Now, however, he feels the situation is so dire that he is quite comfortable making a 100 year prediction because he feels that no one will be alive then to prove him wrong. Bummer man or what?

There is another aspect that is not yet considered here in this debate.
If the global warming does raise the earth temperature and as a result some of the polar ice melts and that raises the sea levels by say 300mm we are not greatly affected, sure some of our beaches will disappear but who cares.
However large areas of Europe will be under threat of the rising sea levels. This is of major concern over there and already the EEU is reluctant to trade with the countries that don't comply with the Kyoto agreement.
It may well be that in the near future when the EEU has sorted out the problems of admitting the new eastern European member nations that they will refuse to trade with us.
There is already great pressure for this to happen and Australia has already seen some exports to Europe curtailed because of our failure to ratify Kyoto. Notwithstanding little Johnie throwing $100M away again on something that will not work we may well be dragged into complying for financial reasons.
As they say " Its a brave new world we live in and it may not last much longer."

It's just a tad more complicated than that (as I'm sure you are quite well aware Al); where would the extra water come from - the polar ice caps. Given that the north pole is really quite thin, the one could reasonably expect it to come from Antarctica where the ice is miles deep in places.
What would that do to ocean currents? I don't think anyone is quite sure, but as the whole planet is a large thermal engine, I think it reasonable to assume that the changes would be significant, and not necessarily very nice for us as we've become accustomed to the present situation.
Cheers!

Yes, but it's the same C02 that you were given when you were born. We are just recycling all of them molocules.

CO2 and various other gases can act like the glass in a greenhouse - they allow radiant light energy from the sun to enter the atmosphere but then trap the heat energy from the earth (which is at a different wavelength) from escaping back into outer space. The earth is virtually a closed system in terms of particles but not in terms of energy. Unless the same total amount of energy is allowed to escape the earth as falls on it, the earth will either gradually heat up or cool down.
We can die from skin cancer by being fried due to a decreased ozone layer without necessarily leading to global warming.

I can remember when we were heading for an ice age (the fifties )
