Pointing out the current uncertainties re clouds is valid comment but clouds could just as easily serve to amplify the forcing from CO2 as offset it.
Did I miss the memo? I thought the science was settled?No, I also read that the science was settled. 97% of climate scientists are in agreement.
Do you think you know better? On a blog, a car related blog?

Clouds 'could' rinse your car. 'Could' put out a fire. 'Could' fill up a lake.The point is that they are fundamental to the energy equation and you don't know either:
1) The current cloud albedo
2) Future cloud albedo variation
So your equation is invalid. Period.
Svenson claims to predict subtle variations due to space weather in 'The Cloud Theory'

he may or may not be correct, but unless you can predict them your climate prediction is stuffed.

I'm not sure it's right to say we don't know the current cloud albedo
So what was the Albedo yesterday at 12 GMT?Remember the nearest the appendix sources in IPCC's AR4 could get is within a 10% agreement of each other.
Note that a 1% error blows the AR4 forcing values away.
Note also the satellite needs to always be seeing the full, sunny side.
BTW the equation to which I refer is at the CENTRE of AGW, but of course anyone on this thread would already know that.

10% what. You're first post cited numbers but not units. Got a link?Deep breath.
Albedo is a ratio, there are no units. Estimates range from 0.30 to 0.33, a 10% variation. Again, no units.
The reference for this is in AR4 - the appendix dealing with albedo estimates.

There is uncertainty about temperature rise attributed to CO2 - see Ipcc reports. They use probabilistic language.
Gavin Schmidt has gone on the record now, saying the temp rise since 1950 is 70% attributable to CO2. Check his twitter feed.XM5ER said:

Then according to Gavin Schmidt and IPCC's AR4 there can be no more warming because the equilibrium point has already changed.Problem solved.
Isn't science a bh?

Clearly 97% of climate scientists also believe it so by definition the poster isn't the only one. Of course they may not be dumbos so your statement could be correct (although I see no evidence to back it up). But of course if they aren't dumb then how come they have it so wrong (from your point of view)? Therefore if your statement is correct it is also wrong at the same time.
If it is between science and a conspiracy theory I will take science every time. If climate change is in no way affected by man or only slightly affected by man then someone needs to go out there and prove it. By proof I don't mean naysaying of what anyone says I mean experimental proof that can be reproduced. So please go and do the research and present your proof for the world to see and then if that proof is compelling enough for the 97% then that will become science.
Do you understand that science is an endeavour to prove itself wrong and that there are no absolute certainties? What those who argue against man contributing to climate change in a significant way mistake for a weakness in science is actually the strength of science.

That's two posts in a row claiming that because the climate is a chaotic system it's impossible to model. Is this a new 'sceptic' meme? Of course it's possible to model a chaotic system. Using that model and a large number of initial states you can produce a probability distribution of it's possible future states. It's not like it's some unexpected result that the GCM's show warming with increasing CO2. We know the radiative forcing changes for a change in CO2. Why would you expect no change?
How successful has it been so far if you look back at old models, say 25-30 years ago, vs what they predicted for today?TX.

Anyone can pick a random article to support their point of view can't they.
Is there consensus that the earth is in oblate spheroid?
Is there consensus that if you release an apple from your hand it falls to the ground?
Is there consensus that the earth orbits the sun?
You see consensus doesn't mean it is wrong.
If you start from a conclusion and work backwards you will find you are right.

Random article? It was a follow up from when Professor Richard Tol had demolished the original John (not a scientist) Cook's 97% paper. FFS there is no consensus. It is a lie. SKS is a website by a car-fking-toonist.Anyone can pick a random article to support their point of view can't they.
