I wonder if God is laughing or crying at the stupidity of these people who use pseudo science to try and push their agendas. The arrogance and pride of these 'scientist' know no bounds. The problem is that once these doomsayers were on the fringe. It seems with socialist Governments they are becoming more mainstream. Thankfully Obama has taken a decent hit in the US. Hopefully he will wake up to the real world instead of making rash promises he knows he can't keep,

Thanks Bugsy and Ozandy, I stand instructed. It appears (http://www.wunderground.com/climate/SeaLevelRise.asp) that thermal expansion in the last fifty years has contributed to sea-level rise by about one inch (25 mm), more than the rise attributed to the melting of glaciers and the Greenland and Antarctic ice-sheets (IPCC).
So according to the IPCC, sea-levels have risen roughly two inches in fifty years ? My God, that's almost seven feet in two thousand years ! What are we going to do ?! What legacy have we left our great-great-...grandchildren ? Presuming of course, that no governments, no companies, capitalism in general, will do anything about it, ever. And presuming as well that ways won't be found to capture river flows (and Greenland run-off, etc.) for agriculture, industry and human purposes, so that none of it reaches the sea. By the way, for comparison, the reported run-off from the Greenland ice-sheet in 2008 (over and above historical levels of net run-off ? I don't know) of about 1200 gigalitres was roughly equal to all the rains that fell over inland NSW and Queensland recently. How much of that will get to the sea, I wonder ?

Sigh (groan), Atman, johndawsonblog, keith, rpg and others.
AGW has nothing to do with international socialism or anything else like that. In reality....remember that there's the basic science. The provable observations. These sites contain actual Before and after comparisons and on the ground observations. http://www.livescience.com/php/multimedia/imagegallery/igviewer.php?imgid=626&gid=42&index=0 http://www.worldviewofglobalwarming.org/pages/glaciers.html http://asiasociety.org/onthinnerice check out "Green China option" while there. Some 80 US glaciers gone in the 20th century 70 more going. Andean, african and PNG (4th highest mountain in the world) are all decreasing at an unrepairable rate... the snow isn't replacing as fast as it melts. Then refer to the results from satellite "G.R.A.C.E." that shows ground water is drying and hydrological cycles are changing. shows lessening depths of Antarctic/Arctic ice. All this took 10000's of years to Accumulate and it disappearing at an unprecedented rate. It doesn't take rocket science to see the writing on the wall. Tell me what do you think will happen once the water in all the affectd rivers dry up or reduce dramatically? Even the three gorges dam hydro had to shut down for a year because of lack of water water flow. 2Billion angry Asians with not enough water or all those Indians, Bangalardeshees that will be displaced by rising sea water? you lot are worried about a few thousand ....what about the Millions that will try to come here. Have you any idea of what sort o desalination, infrastructure and power will be required to deal with that? Apparently not. Consider the largest one in the world currently copes with a few million Arabs and costs a bomb. Both Wbong and I are trying to make you aware of what is *visible and provable today*. Bugger rows over global temperature starting dates for measuring. We must start preparing now. The politics are between nations nobody is suggesting handing authority to a world government, that's in your heads. Posted by examinator, Thursday, 21 January 2010 2:09:06 PM

Now let's do a little arithmetic.
The volume of ice in Antarctica is estimated at approximately 25,000,000 cubic kilometres, covering an area of about 13.72 million square kilometres. The average temperature of Antarctica is minus 49 degrees Celsius. That's why there's so much snow and ice there: it doesn't melt. Before ANY of that ice could melt (apart from short-term submarine volcanic activity, but that's not what we're talking about here, is it?) temperature has to rise at least 49 degrees Celsius. Who's predicting that? Anyone? Of course, these academics assume melting - hell, the scare gets another publication on their CVs, doesn't it? - but preface every significant statement with the biggest little weasel word in the English language - "if" - then slide into "will" with no shame at all. Pigs might fly, if only they had wings. The authors, either from ignorance or dishonesty, fail to mention that Tuvalu and the Carteret islands are subsiding, nothing to do with sea level rise, nor admit that others, such as Nils-Axel Morner, a renowned sea level researcher, say there is no substantial or unusual sea level rise. Indeed, the process is moving in the opposite direction. There's more snow and ice in Antarctica than previously, as you would expect in a frozen desert. To see for yourself, search Google images for "Mawson's hut, Commonwealth Bay" and see how much more snow is there now than when the hut was being built. Worried by all those television images of ice crashing into the sea? Well, don't worry. That process has been going on for so long it's actually got a name: summer. Notice they didn't mention the cost of doing what they recommend? And these guys quote Bruce Babbitt as an authority. I'm guessing Democrats. Posted by KenH, Thursday, 21 January 2010 2:41:52 PM

Rusty Catheter - What statement of mine are you referring to? Your post is making little sense.
You should read what Fourier said before making such statements. His hypothesis that the atmosphere traps heat is accepted by everyone. He did not say CO2 causes the seas to rise. Personal abuse is the hallmark of alarmists with no facts to back up their argument. Wybong - You forget that this is a computer generated hypothesis based on various climate models,not a 'fact'. Many scientists do not adhere to these models. It is also a highly open to interpretation, hence the widely varying predictions between mini and maxi alarmists. If people generally accept this 'fact' why hasn't the price of seaside houses generally decreased?! Posted by Atman, Thursday, 21 January 2010 6:28:58 PM

I've stopped doing all those nasty things and so have most of the people I interact with... So I'll leave it up to the social engineers, warpped socialists and misguided social democrats to try to work out ways to control the way others choose to behave.
I personally think they and all the miscreants should just be allowed to continue with their self-destructive behaviours, and leave me alone to adapt to the conditions they create. So in doing such I will probably, with millions of others, just continue to enjoy my wonderfully peaceful and enjoyable existance.
Roll on warming/cooling ... who cares ... come dictatorships and the social gulags ... whatever ... I'll simply adapt.
Cheers.
