> Is it still warming? Ok, here we get more contentious.

No, no we don't.

> How much of the warming is down to CO2? Contentious, again

Sadly, not contentious at all. The influence of changing solar output has been looked at again and again. It is not neglected.

> s a warming planet a problem? Again, debatable. Rising sea level and ocean acidification scares aside

So, rising sea levels and ocean acidification are not scares, they are occurring. The Great Barrier Reef is struggling, the Artic ice is retreating.

I can't believe that there are people so determined to stick their heads in the sand.

>Sadly, not contentious at all.

Excellent, then you can give me the percentage of warming which is CO2 driven, with error bounds, and references to 3 authoritative sources for it. Inquiring minds want to know!

[flukus]

You'll find estimates of this in the latest IPCC report, surely an inquiring mind as already read this.

[jfnixon]

Not interested in an IPCC estimate by itself, although you are welcome to cite it as one of the papers if you give me a reference to where I can find this in the IPCC report. I want a few papers, peer-reviewed, which go through the facts and reasoning leading to the conclusion that the majority of warming is anthropogenic. And error bars, I want to know the confidence level in the conclusion.

[Angostura]

What makes you reject the IPCC estimates?

[jfnixon]

I'm not rejecting the IPCC estimate. But I want to see this conclusion--obviously a very important one--in actual scientific papers. Is that too much to ask?

[Angostura]

Not at all- if you want to find them, they're there to be found. You're rejecting them before you've read them apparently. Oh and the IPPC report has plenty of error bars if you want them.
