IPCC errors Fact and Fiction,
Real Climate
Currently, a few errors –and supposed errors– in the last IPCC report (“AR4″) are making the media rounds – together with a lot of distortion and professional spin by parties interested in discrediting climate science. Time for us to sort the wheat from the chaff: which of these putative errors are real, and which not? And what does it all mean, for the IPCC in particular, and for climate science more broadly?
Let’s start with a few basic facts about the IPCC. The IPCC is not, as many people seem to think, a large organization. In fact, it has only 10 full-time staff in its secretariat at the World Meteorological Organization in Geneva, plus a few staff in four technical support units that help the chairs of the three IPCC working groups and the national greenhouse gas inventories group. The actual work of the IPCC is done by unpaid volunteers – thousands of scientists at universities and research institutes around the world who contribute as authors or reviewers to the completion of the IPCC reports. A large fraction of the relevant scientific community is thus involved in the effort. The three working groups are:
Working Group 1 (WG1), which deals with the physical climate science basis, as assessed by the climatologists, including several of the Realclimate authors.
Working Group 2 (WG2), which deals with impacts of climate change on society and ecosystems, as assessed by social scientists, ecologists, etc.
Working Group 3 (WG3) , which deals with mitigation options for limiting global warming, as assessed by energy experts, economists, etc.
Assessment reports are published every six or seven years and writing them takes about three years. Each working group publishes one of the three volumes of each assessment. The focus of the recent allegations is the Fourth Assessment Report (AR4), which was published in 2007. Its three volumes are almost a thousand pages each, in small print. They were written by over 450 lead authors and 800 contributing authors; most were not previous IPCC authors. There are three stages of review involving more than 2,500 expert reviewers who collectively submitted 90,000 review comments on the drafts. These, together with the authors’ responses to them, are all in the public record.
So how did the IPCC get it so wrong?
It would appear that ....... The Age
It is becoming increasingly apparent that it is a load of codswallop.
Beyond a few vested interests and those zealots who have embraced it as a religion, co2 based AGW is a dead issue, the science largely discredited, the proponents caught out BSing and humiliated.
Not one in thousands I have met have agreed with Global warming, they have seen it all before, that is, severe weather patterns etc.
The only factor you have omitted is that there is no proof that any change in climate is anthropogenic in nature.
Ad hominem is the prime tactic of the warmists against skeptics and you have immediately reverted to type, despite dissing the tactic... hmmmmm.
What the real science shows is that changes occur very quickly, the climate tends to change abruptly and plant and animal systems evolve into something new to accommodate the changes in climate.
Christopher Monckton has quite a good mind and I would heed carefully what he says.
You think that there is this mystical moral duty to science that exists whereby people around the world regardless of their economic station in which they live require a huge tax in order to save the planet.
The further the IPCC and cohorts are investigated the deeper the scam becomes....
Do a search for Lord Christopher Monckton. This knowledgeable gentleman speaks most eloquently on the subject.
What I do find interesting is post Copenhagen the gradual and quite subtle backdown by the warmist scientists and followers that the science is absolute, definite and unequivocal.
People who could know better chose to instead wallow in blind faith and ignorance.The alarmist gravy train is unwinding as realisation of the fraud sets in. Hang in there Basilio - there might be a few more squirts of gravy left before the funding is cut.
One thing I've realised is that nobody started out with a hypothesis that humans were warming the planet. Scientists from many different disciplines were trying to understand climate, and the role of human activities only became apparent as the understanding grew.
This morning I wondered why a party with actual policies could be be defeated by a party that had none of merit.
For me it's seeing a thread title that is nonsensical.What are the stages of grief again?
Action does need to be taken.For me it's seeing a thread title that is nonsensical.
Climate change is a thing.
It exists because it has been measured. Nobody was advocating for it to magically appear.
The people who have determined it exists actually prefer that it did not. What they advocate is that we should be aware of what happens as a result.
We probably don't want our children and grandchildren to suffer grief over climate change. But maybe if we, like many posting here, pretend it's not happening then everything will be fine.
Not me.
I got firm aim on some flying pigs.
This is not about "environmentalism."Action does need to be taken.
I think the environmentalists need a better tact then the divisiveness that has gone on. The lefts tactics are starting to fall flat worldwide.
Yeah but being a dick about it doesn't sell. What do you think is going to happen.This is not about "environmentalism."
The science in unequivocal, yet you suggest there is "divisiveness."
That being the case, it has only to do with the divide between knowledge and ignorance.
Indeed. The simple may not realize who is simple and who isn't, however.Simple people fall for scare campaigns.

So I came here for inspiration:
People who could know better chose to instead wallow in blind faith and ignorance.
Their justifications were creative when they weren't plain evasive.
What the average punter doesn't "get," because of the polarisation stirred by vested interests against the science, is best summed up below:
Circumstances never changed, and nor did the evidence - we just have more now.Unlike some people, when the circumstances and evidence change, I change my opinion. Quoting me from 9 years ago is not appropriate in this case.
Circumstances never changed, and nor did the evidence - we just have more now.
I carefully read your posts.
You selectively chose information to make a case, and that's pretty standard practice for those in denial of climate science.
