All I can add to that headline is: No sh!t Sherlock.

Beam me to Planet Gore !

[LibWhacker]

Thought can warm the planet more than carbon dioxide?

(sorry, couldn't resist)

[Right Wing Assault]

The climate may be less sensitive to carbon dioxide than we thought

What is the "WE" stuff?

[SpaceBar]

Climategate II damage control.

Water vapor is a larger greenhouse factor than CO2

The “New Scientist” is a left-leaning eco-friendly publication. For them to admit even a bit that CO2 is not this generation’s chicken-little pollutant shows progress in having the truth reach a closed-mind audience. At some point they will have to conclude that they have bet on the wrong science and will have to admit that AGW skeptics were correct.

“However, the finding comes from considering just one climate model, and unless it can be replicated using other models, researchers are dubious that it is genuine.”

Right ... running a computer model is the same as doing an experiment in the real world. Models can't be tweaked. Models are infallible — provided that two or more models produce the same answer. < /delusional warmist ravings

[South40]

Are you telling me this was a lie?

[ROCKLOBSTER]

You don’t need a stupid study.

There is virtually NO CO2 in the atmosphere.

[E. Pluribus Unum]

However, the finding comes from considering just one climate model, and unless it can be replicated using other models, researchers are dubious that it is genuine.

Hell, their computer models can't even predict today's climate, but any model that disagrees with theirs has to be held to an infinitely higher standard.

Oh, these poor boobs. There's a ~60 year cycle, believed to be astronomical in origin, that accounts for nearly all the warming between 1970 and 2000. The increase in CO2 since the beginning of the Industrial Revolution was triggered by the warming of the Medieval Climate Optimum.

The best estimates say that if the amount of carbon dioxide in the atmosphere doubles, temperatures will rise by 3 °C. This is the "climate sensitivity".

My understanding is that the "climate sensitivity" refers to how much of a positive feedback they are assuming in the system. That is, they assume that adding some CO2 increases the amount of moisture which increases the temperature.

A number of researchers believe that the effect is exactly the opposite, that increasing the CO2 increases moisture which increases clouds, thus decreasing warming, that is, a negative feedback effect. Those researchers say this is much more likely, because we do not see small increases in CO2 causing a rapid acceleration in heating, which is what would happen with a positive feedback system.

It is my understanding that all the models the "climate change" crowd depend on have this positive feedback mechanism built into them. It is the only way they can produce the warming effects that they desire.

I have simplified things a good bit for brevity, but the essence is correct, I believe.

Schmittner agrees it is too early to draw firm conclusions. Individual climate models all have their own quirks, so he wants to try the experiment with several models to find out if others repeat the result.

If Schmittner wants to keep his job, he better check with the gubmint, and see what "they" want the temps to be.

[Jukeman]

Politicians, environmentalists, et al never pay attention to factual evidence.

[Publius6961]

This is old news. Many years' old news.

Any presumably educated person conversant with science (chemistry, physics, biology) would be presumptuous to pretend to understand the painfully complex process of worldwide weather and climate based on simple laboratory experiments.

Any self-described "scientist" who would do so, is simply --- well, incompetent.

[desertfreedom765]

It may not warm the planet as much as they thought... But they still want us to reorder our lives and pay trillions more in taxes. Go figure.

[libbylu]

DUH.

[BAW]

The climate may be less sensitive to carbon dioxide than we thought

I'm shocked. Shocked.
