No matter how well the world controls emissions of greenhouse gases, global climate change is inevitable, warn two new studies which take into account the oceans' slow response to warming.
Even if greenhouse gases never rise beyond their present level, temperatures and sea levels will continue rising for another century or more because of a time lag in the oceans' response to atmospheric temperatures, say researchers.
This time lag means policymakers cannot afford to wait to tackle climate change until its consequences become painful, because by then they will already be committed to further change, they urge. "The feeling is that if things are getting bad, you hit the stop button. But even if you do, the climate continues to change," says Gerald Meehl, a climatologist at the US National Center for Atmospheric Research (NCAR) in Boulder, Colorado.
Meehl and his colleagues used two sophisticated computer models of global climate to predict what would happen under various scenarios for greenhouse gas emission controls, taking into account the oceanic time lag. Their most optimistic scenario - in which atmospheric concentrations of greenhouse gases are capped at year 2000 levels - would require severe cuts in CO2 emissions, far beyond those set in the Kyoto protocol.
But even this optimistic scenario predicts that global temperatures would continue to rise by between 0.4°C and 0.6°C over the next century. That increase is comparable to the increase in global temperature during the 20th century of about 0.6°C. A second, independent study using a simpler climate model by Tom Wigley, another climatologist at NCAR, paints the same bleak picture.

There is a simple fix for overheating--just reduce the amount of sunlight hitting the earth. You do this with artificial "clouds", which can be placed in stationery orbit between the earth and the sun, to reduce the amount of sunlight by about 1% or 2%. The "clouds" would be invisible since you would have to look direclty into the sun to see them (and even then they would be pinpricks in size.)
Next problem?
This is an interesting concept.
I read about another proposal (waaaaay in the future) to install a geostationary lens over Mars in front of the Sun to warm it to Earth-like temps.
Screw the grandkids: I'm cold now!
How well are you fixed with parkas and snowshoes?

So, basically, the Earth was it's warmest ever during the Roman era???
Am I wrong but in your last graph it looks like every 100,000 years or so there is a warming that is similar to what everyone seems so concerned about. If so whats different this time?
Well, in the last 10kyrs it would appear so. Going back in geological history it has been much warmer, world wide average about 14 degrees and more.
It's nor often that my BS meter is triggered that soon into a posted article.
This article assumed two things which are far from being proven scientifically, and indeed may never be proven:
a) That warming is is anthropogenic
b) That man is capable of having any effect whatsoever no matter how much resources are thrown at global warming.
In short, it's a latest iteration of an old natural cycle and BS can't affect it one way or the other.
The effects of ignorance can spread around the world at the speed of light, and the insane are now venerated as wise... a most curious combination.

Nothing is different.
That 100kyr cycle appears to be due to precession of the earth's orbit in and out of the solar system mean planetary plane. Seems during the cold spells the earth intersepts more metoric dust and such for high level cloud formation which reflects sunlight away from the earths surface cooling us down most of the time. For 10k out of every 100kyrs we get less dust & fewer high level clouds.
At least that seems to be the main factor from Muller's research.
Global warming beats the alternative.
Actually, I hear that when the dinosaurs roamed Alaska was subtropical and the tropics were damn near uninhabitably hot.
I hope the article is simply saying that we can't very well affect climate change, but we can start preparing for its inevitable consequences.
I'm buying stock in suntan lotion and beach chairs and dumping my snowblower shares!
The latest excuse from the Green whacko alarmists ...
Give ... me .... a break!
"Actually, I hear that when the dinosaurs roamed Alaska was subtropical and the tropics were damn near uninhabitably hot."
We've been freezing our keisters off in Ohio this year. Today it's going to get all the way up to 40.
Bring on global warming.
0.4-0.6C? (1-2F) WTF!!!! THIS AIN'T NOTHING!!!! The temperature in my house changes more than that between the times the furnace turns on and off!!!!!
Accourning to these "experts", sounds like the only thing left to do now is to wrap our arms around our knees, place our heads between our legs, AND KISS OUR A$$ES GOODBYE!!!!!
Yeah...I am in Akron and the snow finally melted yesterday...and it might hit 50 Saturday which is only normal-but will feel great considering it hasn't broke freezing in a month!!
