Himal: next problem

Moving on

Time now to examine The IPCC's assessment of melting Himalayan glaciers has also been criticized as being "horribly wrong" by to John Shroder a Himalayan glacier specialist at the University of Nebraska. According to Shroder, the IPCC jumped to conclusions based on insufficient data. Donald Alford, a hydrologist, said that his water study for the World Bank demonstrated that the Ganges River only gets 3-4% of its water from glacial sources - casting doubt on the claim that the river would dry up since its primary source of water comes from rainfall. [91] 91 is http://www.sciencemag.org/cgi/content/summary/326/5955/924 which is behind a paywall, so I'm guessing its being inaccurately paraphrased. Anyone out there with access care to toss me a copy? Email enabled... William M. Connolley (talk) 23:28, 4 January 2010 (UTC)

It is reprinted here. --Kim D. Petersen (talk) 01:06, 5 January 2010 (UTC)
Maybe I missed a link, but that does not look like the original Science paper. --Stephan Schulz (talk) 01:17, 5 January 2010 (UTC)
It may not be - i may have jumped the gun by surmising that since it is the same author, same title, copyright AAAS and that the style looked consistent to the commentary section - that it was the same. --Kim D. Petersen (talk) 01:22, 5 January 2010 (UTC)
Ah, but maybe that is it. In which case its a straight rip-off of AAAS copyright and you're very naughty for linking to it William M. Connolley (talk) 01:24, 5 January 2010 (UTC)
Someone sent me the pdf (ta). So I can confirm that Kim's link is correct. So: (one of the) troubles with the text above is that it is context-free: there is no ref to *what* is supposed to be wrong. In the article, there is extensive analysis. I don't think that is right William M. Connolley (talk) 22:42, 5 January 2010 (UTC)

IPs etc

I have semi protected the page. There have only been a couple of new user IP or sock edits but when we are trying to keep 1RR and keep edits uncontraversial it is going to cause deterioration if they carry on. --BozMo talk 08:22, 7 January 2010 (UTC)

Thanks William M. Connolley (talk) 21:44, 8 January 2010 (UTC)

Article cleanup templates

I have reverted an edit that moved an article cleanup template to the talk page. Convention on WP, which is consensus by default, is to place these templates on the article. I know they are ugly and I would dearly love to not have them. However, they serve to alert the readers and the editors of WP about any article issues. This is not the first time that I have seen climate change article editors moving templates from climate change articles. It should be noted that policies and guidelines are applicable to the whole of Wikipedia. Please fix the relevant problem BEFORE removing the templates. -- Alan Liefting (talk) - 22:32, 8 January 2010 (UTC)

As far as I can tell, there is no single raw link in the article. Links are far from perfect, but the template is plain wrong. Please apply more discretion. --Stephan Schulz (talk) 23:06, 8 January 2010 (UTC)
Have a look at the References section. There are plenty of bare urls. Please apply less accusation. -- Alan Liefting (talk) - 23:30, 8 January 2010 (UTC)

Unsourced text in 'Physical modeling debate' section

I've noticed that the section 'Physical modeling debate' seems to contain original research (in bold):

MIT professor Richard Lindzen, one of the scientists in IPCC Working Group I, has expressed disagreement with the IPCC reports. He expressed his unhappiness about those portions in the Executive Summary based on his contributions in May 2001 before the U.S. Senate Committee on Commerce, Science and Transportation:

The summary does not reflect the full document... For example, I worked on Chapter 7, Physical Processes. This chapter dealt with the nature of the basic processes which determine the response of climate, and found numerous problems with model treatments – including those of clouds and water vapor. The chapter was summarized with the following sentence: 'Understanding of climate processes and their incorporation in climate models have improved, including water vapor, sea-ice dynamics, and ocean heat transport.'[3]

The Summary for Policymakers of the WG1 reports does include caveats on model treatments: Such models cannot yet simulate all aspects of climate (e.g., they still cannot account fully for the observed trend in the surface-troposphere temperature difference since 1979) and there are particular uncertainties associated with clouds and their interaction with radiation and aerosols. Nevertheless, confidence in the ability of these models to provide useful projections of future climate has improved due to their demonstrated performance on a range of space and time-scales.[4]

These statements are in turn supported by the executive summary of chapter 8 of the report, which includes:

* Coupled models can provide credible simulations of both the present annual mean climate and the climatological seasonal cycle over broad continental scales for most variables of interest for climate change. Clouds and humidity remain sources of significant uncertainty but there have been incremental improvements in simulations of these quantities.

* Confidence in the ability of models to project future climates is increased by the ability of several models to reproduce the warming trend in 20th century surface air temperature when driven by radiative forcing due to increasing greenhouse gases and sulphate aerosols. However, only idealised scenarios of only sulphate aerosols have been used.

In my view, this is an unsourced commentary on Lindzen's viewpoint, and should be deleted. If someone wants to comment on Lindzen's viewpoint, then they should provide a source. For example, Sir John Houghton has given evidence to the House of Lords on Lindzen's views. Alternatively, you could simply refer to supporters of the IPCC, e.g., other climate scientists, statements made by national science academies, etc. and let readers make up their own mind.Enescot (talk) 18:43, 25 June 2009 (UTC)

Good point. Looks like somebody has taken care of the problem by removing the lengthy excerpts and just using a quote from Sir John. Definitely an improvement. Thanks.--CurtisSwain (talk) 23:01, 16 September 2009 (UTC)

Fixed. Please add new topics at the end (you can use the "New section" button). Thanks. --Stephan Schulz (talk) 22:40, 16 September 2009 (UTC)

We need discussion & resolution of the self described "Scientific" vs. "Advocacy" characterization

The problem relates to the first sentence of the article as it appears as of 12-12-09 emphasis added:

The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body[1][2] tasked with evaluating the risk of climate change caused by human activity.

Should the term scientific be used to describe the IPCC, notwithstanding the fact that the IPCC itself goes to great length to characterize themselves as such: "The IPCC is a scientific body."[19] But we find what appears contradictory in the same article:

The IPCC does not carry out its own original research, nor does it do the work of monitoring climate or related phenomena itself. A main activity of the IPCC is publishing special reports on topics relevant to the implementation of the UN Framework Convention on Climate Change (UNFCCC),[4] an international treaty that acknowledges the possibility of harmful climate change.

and

The IPCC is only open to member states of the WMO and UNEP.

It doesn't seem right to call the IPCC, a United Nations body, a self described intergovernmental body, as a scientific body. It also seems wrong to deny the central purpose of the UN, influencing policy and conduct of its member nations. Let's consider by analogy, the publishing arm of University is not a scientific body. The credit union which provides banking services to members of a University is not a scientific body. Perhaps they are regulators, or a policy think tank. I don't dispute that they are commenting on the scientific reports and data of some scientists, academics, & researches. Clearly the operation of the IPCC has had affects on politics, policy, and perhaps legislation around the globe. I would like to suggest that the word scientific be removed and inserting "policy influencing" or "advocacy" at the same location. Obviously this particular issue has had some attention with less than a perfect record of civil discourse. So Please let's discuss this in a civil manner. The issue to discuss in this role is not Global Warming, but how to accurately characterize the IPCC. These are two separate questions one for the deletion of an adjective, one for the inclusion of an adjective. 1) Is it a scientific body? 2) Is it a body for policy influence or advocacy? This article needs some sort of organized resolution of these two questions perhaps with the assistance of some experienced editors / administrators. -- Knowsetfree (talk) 01:56, 16 December 2009 (UTC)

1. Yes. 2. It is a body whose results are used for political purposes, just like lots of other scientific research, but which is itself largely non-political William M. Connolley (talk) 08:39, 16 December 2009 (UTC)
1. Yes, since it's composed of scientists. There are interests behind almost every scientific study. They're payed for by governments, companies and advocacy groups. They will always get their money from a particular group of people with particular interests. That doesn't mean they won't follow scientific principles and methods. 2. It's a scientific body whose results are used for policy influence.--camr nag 16:01, 16 December 2009 (UTC)
1. Sure. Al-Jazeera, Sydney Morning Herald, BBC, Guardian, Royal Society, ... --Stephan Schulz (talk) 16:31, 16 December 2009 (UTC)
1. No. Some of the lead authors are economists, not scientists e.g. Kenneth Arrow. 2. Judging by the contents of its public reports, it is focussed on advocacy - note for instance http://www.ipcc.ch/pdf/10th-anniversary/anniversary-brochure.pdf - the summary of each IPCC report has a followup section advertising what impact that report had on the government COP meetings that followed. The IPCC clearly measures its performance against its influence on those meetings. Cadae (talk) 09:45, 23 December 2009 (UTC)
So, economy is not a science? Also, any scientific body that discovers that X is bad, would not cease to be scientific if they actually say "hey, X is bad". If doctors discover that smoking is bad for your health and recommend their patients to stop, then their licences should be revoked?--camr nag 14:52, 23 December 2009 (UTC)
Correct - economy is not a science. Scientific bodies don't use the word or concept of 'bad' as that is a value judgement which is distinctly not science. 'bad' is, however, liberally used in the realms of politics and advocacy. Cadae (talk) 19:26, 23 December 2009 (UTC)
ok, you've said it all.--camr nag 19:42, 23 December 2009 (UTC)
1. Yes. This complaint seems very partisan against the IPCC. The contributing authors for the Assessment Reports bring in most of the top scientists in the field - highly cited, widely published, many elected Fellows of learned societies including the AGU, AAAS, National Academy of Sciences, etc. 2. Yes, the IPCC sets out the basis for concern and the need for a broad response to the implications of their findings. The whole point of forming the IPCC was to have a forum where leaders could inquire of scientists what the science tells us, and what the implications are - what is the problem and what would we have to do to address it. Do you want to argue that no scientist can ever discover facts that compel us to respond? Is all science only ivory tower, irrelevant theory? Birdbrainscan (talk) 23:04, 24 January 2010 (UTC)
