Melting tipping Point for Greenland ice-sheet.
Oct 24^th, 2013 at 12:15am

Earlier this year I attended a public lecture given by David Spratt. One important highlight that emerged from this informative lecture was the survivability of the Greenland ice sheet as the earth warms.

Will the Greenland Ice Sheet survive if the Arctic were sea-ice-free in summer and winter?

“not only is ice sheet survival unlikely but its disintegration would be a wet process that can proceed rapidly” – James Hansen

The tipping point for Greenland revised to 1.6 deg C above pre-industrial (uncertainty range is 0.8 to 3.2 deg C)
(Robinson et al., Nature Climate change 2: 429-432)

Paleo-Climate record shows that Greenland ice-sheet formed at less than 400 ppmv and we are at these CO2 levels now.

David Spratt’s opinion is that we have already crossed the Greenland ice sheet melt tipping point and we will only know in retrospect.

Get your atlases out ladies and gentlemen and check out HOW big Greenland is and find out how thick the ice sheet is.

So what?
Greenland melts...it disrupts the Atlantic conveyer...stops the Gulf Stream and before you can say Jimminy Cricket...you have an ice sheet again...only bigger...then you can have lots of sea ice...you should be up there with a hair dryer!

No just showing the absurdity of your link between global temperature and CO2.
In any case you think the burning of fossil fuels was a huge mistake...which drove the industrial revolution...which gave you many of the things you take for granted...and without the industrial revolution you would probably be in some hovel somewhere wondering where your next banana was coming from. So I hope you're not taking all these benefits...otherwise...you're a hypocrite.

I see.... so now you are claiming that CO2 is NOT a greenhouse gas

How many doublings of CO2 to get to 7000ppm? Start at 300ppm. (The actual figure from Geocarb III is between 2000 and 8000 ppm.)

Allow 3 degrees per doubling as a rule of thumb. Multiply the number of doublings by 3 and add 4 degrees (current deep ocean temperature.) That should give you the approximate ocean floor temperature during the Cambrian period, with the usual high error for 500 million years in the past.

What do you get? Does that come close to Boiling Point?

Forgot to mention water acidity... Embarrassed

How far are we talking from volcanic vents here?
Sea bed?...you are familiar with the concepts of shallow and deep and the resulting differentials in temperature?
But on average...and taking into account the current temperatures of both...and the indisputable fact that CO2 and temperature are absolutely and completely linked as handed down on the Al Gore tablets...and diffusion effects...that would be...let me see...carry the one....17.5 times...oh... unless it's all crap.
