Greenland ice loss double in past decade, Nasa says

I have always believed global warming is part natural, part man made. As Attenborough states:

" The coincidence of the curves made it perfectaly* clear we have left the period of natural climatic oscillation behind and have begun on a steep curve in terms of temperature rise, beyond anything in terms of increase that we have seen over many thousands of years".

"many thousands of years..." ?


like this temperature history:

Considering the difficulty of measuring "global climate" that is a bold statement from Sir David. There are a number of temperature proxies, and the data does show some ambiguity.

I plead guilty

So will anyone of us change our behaviour? and if we do will it change things now?
I am minding 200 acres of trees that will never get cut down whilst I am alive and live off solar power when at home there. That not green thats just the place I find myself in... if I had the cash I would have a v8 and an airconditioner and if I wanted a black tin roof I would have it and but yet another airconditioner..as they do..The reality with the world getting richer things can only heat up that is inevitable...in fifty years you will need to be really rich to enter the hobby of astronomy because you will need a hubble space scope ..the clouds of "mist" over Earth wont permit viewing from the surface of the planet..So dont wait to buy that bigger scope..time is running out
It is my opinion that Global Warming is happening however I have seen evidence to suggest it is not just humans contributing, so the prospect of natural and "artificial" contributors may need to be reconed with.
It is also my opinion that certain "clean fuel of the future lobbiest" are using our guilt of over consumption to grind their own axe however. Well folks what do you want cancer or slow grill.

Roll on the next ice age, I say. It is already 2000 years late. I reckon property prices in Brissie will go through the roof and I can make a killing and then retire to a colder climate where they are all bailing out from....

The Gold Coast may become a skin divers paradice with the predicted water level rise.

the question now i guess is, do we try and stop nature from doing its thing or let the ice caps melt, water levels rise and ice age roll on?

I think if you look realistically at the rapid development world wide, not withstanding the best intentions of reduction setting goals, caring people who do the right thing or cutting your shower time by half, the problem will get worse. Any effort to "fix" it will be only by those with a vested interest in the product they present as part of the cure... commercial considerations say we will have to face and manage the consequences of no action. But there is sometimes some good from even the worst case, the eventual degrading of the planet may see more advanced political and economic systems than humans had needed before.
But what a neat part of history we are living in.. the begining of the end or the end of the begining.
