Nah, I've read before that more and more carbon dioxide can't absorb as much extra energy, which leads to less and less warmth.
I won't find a link tonight, but I'll see what I can find tomorrow.
What do you make of this graph Livers? Mostly sun related, despite the fact scientists think the sun has only gotten stronger in the last 15-20 years?
Blue being the long term trend, black being the actual averages and red being the departure from the mean.
Don't bother finding the link. You do understand that the main principle of the greenhouse effect is that carbon stops the heat from leaving the atmosphere?

Fair enough, it's an extreme case, but that's the point. No one knows what effect continuing to pour carbon into the atmosphere will have. I don't think it will happen because enough people seem to be taking it seriously now, but I'd be worried if more people shared Livers' views.
The area of melting in 2002 broke all previous records [ACIA, 2004]. In 2006, estimated monthly changes in the mass of Greenland's ice sheet suggest that it is melting at a rate of about 239 cubic kilometres (57.3 cubic miles) per year. These measurements came from the US space agency's Grace (Gravity Recovery and Climate Experiment) satellite, launched in 2002, as reported by BBC News, 11 August 2006.If the entire 2,85 million km³ of ice were to melt, global sea levels would rise 7,2 m (23.6 ft.)[IPCC, 2001]. Recently, fears have grown that continued global warming will make the Greenland Ice Sheet cross a threshold where long-term melting of the ice sheet is inevitable.

How is that number arrived at? The reasoning all seems a bit murky to me. I just had a look at that wiki and there is some good information there (it seems George Monbiot made the indulgence claim, perhaps I read it somewhere and it stuck). While reforestation is good I fail to see how future potential carbon sequestration can completely compensate for increasing current emissions.

you are full of crap. Its not that you don't want us to panic, none of us do, you don't wan't us to do anything. You see any recognition of the problem and action as panicing. Its not, its recognising a problem and acting.
As for the extreme claims, again as I've pointed out time and again, you point to an extreme scenario to dismiss the whole debate. Its not a valid arguement. A 1 metre rise in sea levels over the next hundred years has real implications.
As for the arctic melting, well, it is. The area of polar ice is shrinking. Its not rubbish, and the tone of your dismissal really exposes the level of ignorance.
And again, we don't have to change our entire lives. Just be smarter how we do things.
As I've said before, its completely pointless arguing with you, yet I keep doing it. We all pick off your aruments that you can drive a truck through one by one, but you are completely oblivious that its happeneing. Or you'll occassionally concede a point, but then hammer the same point a few weeks, or days later as if it never happened.
Plant a tree livers. It's good for the soul. If you don't think it will help lessen global warming the birds and insects and koalas will still be grateful and future generations might just benefit from that 2 minute effort. If you don't have anywhere to plant a tree I'd be happy to plant one in your honour.
Rosy,are any of the farmers in your area looking into these government schemes that pay to plant trees.I think future governments are going to be more agressive with this funding as time goes on.A good opportunity for struggling farmers.rosy23 said:
It's an opportunity I'm thinking of looking at in a few years myself.
A Northern Victorian 'tree change'
20 billion trees cleared in Australia since 1788, and the pollies think it's still fine to let the likes of Mitsubishi buy contracts to turn our old growth forests into paper. Morons. Greedy *smile* morons.
My neighbour has a lot of trees from a different scheme (greening Australia) but I've never done it because with the way the weather had been we just didn't have the water to keep them alive.
