$this->bbcode_second_pass_quote('Raxozanne', 'T')hat's a huge jump in temperature. Seriously, if Greenland melts then a lot of humanity is going to go underwater (especially in the Bangladeshi flood plains).

[Raxozanne]

$this->bbcode_second_pass_quote('rwwff', '

[FishAreBest]

$this->bbcode_second_pass_quote('Raxozanne', 'I')'m not sure but if it's over 1 metre then 40 million bangladeshies will have to move shop.

Think about the weigh of all the ice sheets. As that weigh comes off the land - Earthquakes! Massive earthquakes.

[rwwff]

$this->bbcode_second_pass_quote('Heineken', 'I') don't see why this constantly gets framed as an "either/or" question.

[NEOPO]

yadda yadda just can't say anything now can we?

99.999999% simply wont do now will it?

Not enough for you to give up your addiction anyways certainly not.
Hell!! you dont even have a problem now do you?

ya see - GW and PO both insist that you will sooner or later realize that you are an addict.
An addict to an unsustainable lifestyle and it will have to change and its gonna hurt when that time comes and I get the weird feeling its just about any day now wether by PO or GW or both.

Who am I kidding - its happening already or none of us would continue to rant here.

Think of it as a brain completely outside of its body - useless - lifeless - programmed to have as little thought as possible - and even when you put the brain back into the body cavity it simply dysfunctions.

[Keymaster]

rwwff, that's quite a convenient argument. The earth is in a natural warming cycle, and humans are merely subservient to its awesome forces.

Why bear the burden of guilt, which we - Americans in particular - should bear?

But the facts speak for themselves. The earth's typical warming cycle occurs thousands of years slower than the current warming period. Yet you cite prior temperature variations as compelling evidence that humans are powerless to mitigate or - indeed - even induce global warming.

It's quite clear, meanwhile, that manmade pollutants have accelerated the trend to an astonishing degree. If warming were occuring naturally, then your children, and generations to come, wouldn't have to worry about the immediacy and extent of the problem confronting humanity.

Does anyone know if measurements of temperature at the *base* of the Greenland icecap have been monitored ? I just saw a show on volcanic activity and they talked migration of magma chambers beneath the surface and how that causes increase in surface temperatures. It seems like this would melt stuff pretty fast. Or, is the melt attributed and explained only by air temperature increase ?

I'd appreciate it if everyone would simply take their blinders off, admit that we are going to rapidly and inefficiently burn off all the oil and as much coal as we can dig out of the ground


My feelings exactly, the dishonesty and utter bullshitting annoys me far more than the actual CO2 emitting, we're all responsible.

[JoeCoal]

I just saw Al Gore's An Inconvenient Truth. The similarities between the Larsen B Ice shelf collapse and what’s happening to Greenland right now were extremely chilling, no pun intended. Highly recommended if you haven’t seen it yet.

We’re in a race between runaway GW and running short of oil in time to stop GW…

[rwwff]

And you can demonstrate a way to stop GW while continuing to operarte all the coal fired generators in use today and those that will be built over the next few years?

[JoeCoal]

No, of course not. But at least I live on high ground...

[rwwff]

$this->bbcode_second_pass_quote('JoeCoal', 'N')o, of course not. But at least I live on high ground...

It is clear that the northern hemisphere is rising in temperature, but I read little about the southern, and what I do leads me to believe it is stable or cooling. Does Gore talk about the southern hemisphere at all in his big powerpoint presentation? I know there is one ice shelf that is melting there (it started melting 8,000 years ago according to scientific evidence), but the rest of Antarctica, including the middle, is growing with ice.

"This thickening correlated very well with the snowfall modelling, showing that the increased snowfall is causing the ice sheet to grow in mass. We estimate that the ice sheet is holding an extra 45 billion tons of water each year, the equivalent of a sea level drop of 0.12mm a year."

Unfortunately, the same scientists say the Greenland ice sheet is melting at a 0.20 mm a year equivalency of sea level rise.

There is at least one other longer term issue for antarctica to think about.. The thicker the interior becomes, the more force that is applied to drive outflows. You could get some very near term moderation in sea level rise at the expense of much more rapid rise later.
