The only tipping point we should really worry about is the global warming cults tipping point into madness which has already been reached judging from this board.    Cheesy


you're right - its all one big scam that has hypnotised every scientific body in the world, as well as every fossil fuel corporation



Are you talking to yourself?

Why isn't the water boiling?
And those yummy looking seafood dead?
Guess it's not that hot after all!!!


When did the first mammals appear in earths history?

When did the first hominids appear?

You want to return Everybody and everything to the comforts of a 0.7% CO2 atmospheric level?

Where do you get your lies from?


No just showing the absurdity of your link between global temperature and CO2.
.


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


Again...you misrepresent me...and greenhouse gases for that matter...ALL OF THEM...they are beneficial and make the planet habitable.


water is essential for your well being as well, too much at the wrong time in the wrong place and you drown

whats your point?

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.



THE PASSING OF 450 PPM is inevitable according to atleast Dr David Mills- the canadian who studied in Australia to come up with i forget the solar thermal mirror blah blah blah of something that wen tto america because australai didn't care etc... i've written this many a time and we all know iT!(IT'S ALL ON YOUTUBE AND I SUPPOSE BEYOND  Roll Eyes Roll Eyes Roll Eyes Roll Eyes Roll Eyes NOT THAT ANYONE CARES  Cheesy Grin  Cry Cry )

BOTTOMLINE: THE 450 PPM CHICKENS ARE AS GOOD AS ROOSTED!

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!





rates of change are dangerous: THAT'S WHAT!!

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.

NAZIS TRY AND OWN LANGUAGE!!

Well you brought it up. What was the air temperature and the sea bed temperature?


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.

WAIT WAIT:: WHEN DID GRASS COME ABOUT???

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?


Rules of thumb....nice to know. So say we had zero CO2 (besides being a real bummer) what would the average world air temperature be? seeing as it's 15 degrees now?


About -18 C is what I've seen quoted.





That's no atmosphere at all at -18 C or 33 C lower from the present...so by that measure 100% of the atmospheric greenhouse gas is CO2 as the sole gas responsible for warming...interesting...do you have that one locked in?... or might I suggest you phone a friend...

Just as a matter of interest would you consider gaseous H2O a gas?



What happens to the vapour pressure of H2O as you drop the temperature?

Alarmists also told us there would be no ice in the arctic by 2013...LOL....????

But there is nothing out of the ordinary about the arctic and Greenland melting.

During the medieval warm period the glaciers on Greenland were all but gone.

That's why it was named green land.

In the 1940's it was also reported that Greenland and the arctic where melting at alarming rates.

Yet here we are today and we have ice on both.

Mr Ajax

Are suggesting that CO2 concentration in the earths atmosphere can be increased to any level and not have any effects on the earths thermal retention rates, ice cover, climate etc?

Have you decided what proportion of the fossil fuel reserves should be burnt as quickly as possible, how much forest cover is allowed for the planet, what CO2 level is permitted?

Have you designed the future for ALL of the earths inhabitants as well as all of the other species of life?

Are you the ultimate judge of risk, for all of humanity?

All because you don't want to pay any taxes but wish to benefit from what taxes deliver

...like the internet which you are using right now, as well as the computer chip which is running your PC - all innovations of the tax payer funding model.

If it concerns you so much why not live alone on a desolate island somewhere?

I know that there are plenty of Australians who prefer to shift their citizenry and therefor their tax liability to various small island nations,

Why would they do that Mr Ajax?

Ajax, Wieslaw Maslowski works for the US Navy Polar Ice Prediction System. He might have written a paper on polar ice, but it was one of many. Just because one researcher gets it wrong doesn't imply that there was any consensus.

Perhaps if the level of Chinese aerosol pollution was less, he could have easily been right.

...an easy exercise or calculation can be done to account for all aerosol emissions that act as dimming agents in the earths atmosphere

In fact the sluggish warming or static temperatures measured during the 1945 to 1965 period can be attributed to the elevated presence of aerosols from global industries that had poor or NO emission treatment or filtration systems installed. During this period the atmospheric CO2 level had not reached 320 ppmv. We are looking at about 400 ppmv today

We also know that the large volcanic eruption in the late 1990s also caused a suppression of thermal retention rates.

In any case, if CO2 levels continue to rise the thermal retention rates will trend upwards triggering various known and unknown tipping points. (in fact even if the CO2 level stabilised TODAY, there is a latency in the system that will still cause warming)

Hard times ahead - especially for AUstralia which will be hit very severely depending on where people and species reside on this vast continent
