Michael Mann and the "hockey stick" exonerated once again;

"An Investigatory Committee of faculty members with impeccable credentials" has unanimously "determined that Dr. Michael E. Mann did not engage in, nor did he participate in, directly or indirectly, any actions that seriously deviated from accepted practices within the academic community for proposing, conducting, or reporting research, or other scholarly activities."

That implies there is some predetermined conclusion the IPCC is endeavoring to support. Please give us evidence of such fraud or retract your post.

No no no, not the IPCC, it's the people trying to misrepresent the IPCC that need to support. If you read the reports there's nothing to object to really, they represent themselves accordingly, it's the internet, and the alarmists that distort.

The people that distort the IPCC AR4 are normally called denialists, not alarmist. People like Watts, McIntyre, Inhofe and Monckton.
 
What the heck is Panorama
It's the BBC's flagship political programme.

and what idiocy leads them to believe that there are two seperate opposing and equally legitimate scientific perspectives upon the issues of climate change?
Nothing, because they don't believe that. The blurb suggests no such thing, and the programme made it clear that scientists at the supposedly sceptical end of the spectrum do not dispute that warming is happening or that humanity is responsible for it, they are only doubtful about the severity of the consequences.

They carefully led up to this "surprising" revelation by using a board on which people could register their opinion on questions like "is CO2 a greenhouse gas", "are we warming the planet" etc by placing cards on it. The board went from "Certain" on the left through "likely" then "unlikely" to "No Way" on the right.

The reporter started with members of the public, who were asked "How certain are you that mankind is warming the planet?" Their cards were place right across the board with the majority to the right of centre. Then he asked the mainstream scientists the same question plus some more specific ones; they put their cards in the leftmost column with a few slightly overlapping the "likely". Then he asked a couple of scientists who are usually considered AGW sceptics (e.g. John Christy) exactly the same questions, and they put their cards only slightly to the right of the mainstream scientists.

ADDENDUM: After a brief look at Wiki (because BBC show links apparently only work if you are in England), I now understand, what I don't understand is how sensationalist tabloid TV links and recent political blog discussions are making it on to a moderated discussion board about the science of Global Warming?
Panorama is not "sensationalist tabloid TV".
 
It's the BBC's flagship political programme.


Nothing, because they don't believe that. The blurb suggests no such thing,...

"...Panorama reporter Tom Heap speaks to some of the world's leading scientists on both sides of the argument, to find out what they can agree on and uncovers some surprising results..."​

There is only one mainstream scientific perspecitive on the issue, and there are no "world leading scientists" in the relevent fields of study who disagree with that mainstream perspective.

Panorama is not "sensationalist tabloid TV".

The various episode titles and descriptions certainly sound sensationalist, and to me that is the mark of "tabloid." but then I guess arguments could be made that most TV is sensationalist to one degree or another.

Personally, I prefer my science to come from those who devote at least a good chunk of their lives to learning and researching that information, not from those who are trying to create programming that will keep me interested while they try to sell me toothpaste and laundry soap. Along those lines I would also put 60 Minutes (which sounds a lot like an American version of Panorama), any of the various Discovery/Science Channel shows, and please let's not even get into the "History" channel's idiocy.

I tend to give NOVA and SciAm a bit of a break, because they accompany their shows with supporting websites that further detail the information presented and provide references for further research, but all to often even these are quite sensationalist in their presentation of the material.

That seems to have nothing to do with my question, which was:

Does the IPCC AR4 represent the scientific consensus on climate change?


I am also interested in who these mysterious people are who are attempting to misrepresent the IPCC. Can you tell us who they are in addition to answering the above question?

Which was precisely what the programme demonstrated.

You do know that there are no adverts on the BBC?

You wouldn't know that to read the blurb you posted.

You do know that there are no adverts on the BBC?

There are on BBC America and on the BBC International websites when you try to access programming, but those are the only versions I have access to. There are even advertisements on local Public Broadcast channels here in the US, well, sponsorship statements that largely amount to the same thing, but I tend to give the public broadcast science shows some leeway as I noted earlier, due to the fact that they provide accompanying website materials, information and references so that they can be fact-checked and further researched, if Panorama does the same, I would be inclined to grant it the same courtesy.

Um, I clearly answered "NO". The consensus is on the tenets, not AR4. Misrepresenting that is deplorable.
 
What the heck is Panorama and what idiocy leads them to believe that there are two seperate opposing and equally legitimate scientific perspectives upon the issues of climate change?

Panorama used to be a flagship BBC documentary program covering current affairs, but it was "rebranded" in a shorter and more ... "edgy" format.

The BBC is not what it used to be. Horizon was brilliant once, but is pretty much unbearable since the media-studies people got into it.
 
Would you agree or disagree that the model predictions have been, for lack of a better word "toned back" since the late 70's? If you agree, why? If not I'll have to dig up some papers and go from there.

I don't agree. So get digging.

Do you know what super sensitivity is? I don't think you are.

I suggest you use Preview Post and read through it before you post.

I suggest you read up on it and get back to me.

I might suggest you read up on it. I'm no stranger to Chaos Theory, and this is what you're alluding to, isn't it?



I don't think you fully understand how they input data into the models.

I know full well that you don't undertand what physical models are at all.

Most likely because you're only concerned with the results.

Well, yes. What else does one look for in a physical model other than the output results?

Where they differ from actual results they reveal areas where the physics is not well understood, the focus for further research. If they differ wildly (by, say, "running out of control") they probably need abandoning. But climate models don't run out of control, any more than the climate does.

I'll bookmark any interesting papers I find and post them in this thread as I see them. I'll search for the ones I've read and try to post them here as well.[

Please do.

And clouds, convection, albedo...I'm sure there are others that I can't think of right now.

I'm not so sure. Make an effort.

Land-use change?

I realize researchers never want to admit anything is complete, that closes the flow of funds. But there are many areas that need much, much more study before the models have the fidelity we need to make important decisions on what to do and where.

So lets do nothing in the meantime and wait to see what the big bad analogue model throws up. Then try to cope.

Doesn't that attitude encourage defeatism?

Aside from the fact that I heard this mantra preached 15 years ago? No there isn't a good reason to think we aren't on the verge of a catastrophe. The research indicates it's very unlikely, but not zero.(Sandia 2010)

The Arctic didn't look like this fifteen years ago, did it? Droughts and severe precipitation events weren't nearly so common as they are now. All predictions.

What do you define as the "verge" of catastrophe? Whatever that period might be, subtract fifteen years and here we are.

I'm just no convinced the money isn't better spent on researching mitigation techniques instead of simply raising the kWh rates.

Policy is for the Politics Forum.

The transportation sector needs to substantially reduce CO2. I don't see a lot of research in this area. I know Cummings is researching Liquid Natural Gas (LNG) in trucks, but aside from that I just don't see them making any headway.[

What you don't see is not at issue.

What's at issue is your claim that climate models "run out of control" when "fed with the real data", which you've made no attempt to justify. There's a good reason for that failure.

Yeah, I'm sure I over-reacted, a little more digging revealed at least a few (more than a couple) instances of what seemed to be hard-core, well-investgated and compellingly presented journalism in a sense that you don't often get to use that term anymore. But, between what I perceived as the presentation of false equivilance in the excerpted description, not being able to view the initial link, and a quick scan of a couple search hits which seemed to be highlighting various "gotcha" pieces and political, society rumor rundown pieces,...well, I'm afraid I may have been about to throw out the baby with the bathwater, so to speak, sorry about that, one and all!
 
A Dutch inquiry into the UN's climate science panel has found "no errors that would undermine the main conclusions" on probable impacts of climate change.

However, it says the Intergovernmental Panel on Climate Change (IPCC) should be more transparent in its workings.

The Dutch parliament asked for the inquiry after two mistakes were identified in the IPCC's 2007 report.

The inquiry is the latest in a series that have largely backed "mainstream" climate science against detractors.

Whither 'climategate'?
 
Um, I clearly answered "NO". The consensus is on the tenets, not AR4. Misrepresenting that is deplorable.

I clearly asked
Does the IPCC AR4 represent the scientific consensus on climate change?

Your response is so badly written it's difficult to understand if you are saying the censuses is on some predetermined list of tenets or the AR4 is echoing some predetermined list of tenets. Only the second would actually answer my question but certainly cries for more support on your part because it would constitute a gross violation of their mission to evaluate the best understanding of current science.
 
Scrubbing CO2 from Atmosphere Could Be a Long-Term Commitment

ScienceDaily (July 2, 2010) — With carbon dioxide in the atmosphere approaching alarming levels, even halting emissions altogether may not be enough to avert catastrophic climate change. Could scrubbing carbon dioxide from the air be a viable solution?
A new study by scientists at the Carnegie Institution suggests that while removing excess carbon dioxide would cool the planet, complexities of the carbon cycle would limit the effectiveness of a one-time effort. To keep carbon dioxide at low levels would require a long-term commitment spanning decades or even centuries.


Previous studies have shown that reducing carbon dioxide emissions to zero would not lead to appreciable cooling, because carbon dioxide already within the atmosphere would continue to trap heat. For cooling to occur, greenhouse gas concentrations would need to be reduced. "We wanted to see what the response would be if carbon dioxide were actively removed from the atmosphere," says study coauthor Ken Caldeira of Carnegie's Department of Global Ecology. "Our study is the first to look at how much carbon dioxide you would need to remove and for how long to keep atmospheric carbon dioxide concentrations low. This has obvious implications for the public and for policy makers as we weigh the costs and benefits of different ways of mitigating climate change.

Fundamentally I have a feeling that removing carbon will be a reality and a necessary one.
Even if we went to zero emissions now the warming would continue for several decades.

I have to say much the same, I've watched it now and it wasn't nearly as bad as I assumed it would be.

The icky fingerprints of MediaStudies are all over it, of course, which is what I find most irritating about Panorama now (and even more, Horizon). In terms of construction around the actual information and arguments it wasn't bad, and there was even a hint of journalism in it.

AGW really must be a serious issue :).

potentially, much longer, and that is a problem that too many seem to not understand. It takes a long time for the carbon we put in the atmosphere today to reach its peak warming potential, and its persistence carries that effect on for what may well be centuries or longer (and this is without consideration for other feedbacks).

Carbon is forever


Carbon dioxide emissions and their associated warming could linger for millennia, according to some climate scientists. Mason Inman looks at why the fallout from burning fossil fuels could last far longer than expected...
