On new page patrol, I noticed a new article entitled Climate Security (with a capital 'S'; not to be confused with Climate security, which redirects to Weather warfare). Before flagging article issues, article name, etc. I thought it would be more sensible to suggest merging it with this article, specifically with the section Global warming#Responses to global warming and/or the sub-articles of that section.
Unfortunately, current full protection prevents me from adding {{Mergefrom}}.
If the new article is retained, links to it should probably be added to it from this article and from Index of climate change articles.
I'm not very happy with the Weather warfare redirect from Global security Climate security either. --Boson (talk) 11:38, 5 December 2009 (UTC)
Would you please add global cooling in a "See also" section? I think it's really worth mentioning. Thank you very much :) --Mahmudmasri (talk) 22:57, 4 December 2009 (UTC)
This thing is supposed to be permanently semi, can someone please fix? William M. Connolley (talk) 08:18, 9 December 2009 (UTC)
Several users continue to revert my edits that simply clarify the state of Global Warming in the scientific community. Global warming is a scientific THEORY. It has yet to be accepted as a law, and is therefore not necessarily true. Please stop trying to slant this article towards the left by attempting to project global warming as fact. I only ask that this article be 100% neutral in its point of view, and present the facts as they are known. It is the job of each individual to make a decision based on accurate scientific facts. Thank you. —Preceding unsigned comment added by Bonked116 (talk • contribs) 22:04, 13 December 2009 (UTC)

Discussion ended with conclusion to add a section on pre-human climate change similar to that found when article was promoted to FA Global Warming has only been occurring since the 20th Century? Hell, that's not only mislead, but it's an outright lie, apparently inserted for the ulterior purposes (advancing left-wing political agendas). Global Warming is NOT a new phenomenon. In fact, it has been steadily progressing for the last 12,000 years since the last ice age. Warming itself is a loaded term, implying that there is a "pristine"/"correct" temperature. A more accurate term would be "global thawing" as that's precisely what happens when the planet comes out of an ice age. Akulkis (talk) 02:06, 3 December 2009 (UTC)
Is the horse dead yet? I think so. Everyone, please stop responding to Woodwalker and this will remove the incentive for him to continue this "debate." Rev. Willie Archangel (talk) 18:38, 3 December 2009 (UTC)
Could we please use English? Reading the above I'm trying to wade through a comment that refers to "ABF behavior." If this is a Wikipedia term, please understand that I'm a Wikipedian of some five year standing, and *I* didn't know what ABF means. Imagine what a newcomer thinks. Looking carefully around Wikipedia I realize that the writer means "assumption of bad faith." This is a perfectly good English term. Why replace it with gobbledygook? --TS 22:21, 3 December 2009 (UTC)
Well, some good points have been made here, so it seems the best thing to do is simply change the 1st sentence to read, Global warming is the term commonly used to describe the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Just to make things abundantly clear. So, if nobody objects…--CurtisSwain (talk) 09:20, 4 December 2009 (UTC)
Hans has the best solution. All we need to do is start the article with... Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. More generally the term can also refer to similar events that happened at various times in the past. or maybe even... Global warming is the term commonly used to describe the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. More generally the term can also refer to similar events that happened at various times in the past. That should make it perfectly clear to the average Joe that the article is in no way implying that Global Warming has only been occurring since the 20th Century. There's no need to add anything about past warming, because the hat notes, with their subsequent linkage to Historical impacts of climate change provide for that. We just add a few simple words, and that should stop any accusations about the article being "misleading". --CurtisSwain (talk) 00:46, 5 December 2009 (UTC)
Sorry if I sound a bit negative, but it looks to me as if the latest responses are by people who didn't actually read my explanation and proposal in detail. I know it's TLDR, or at least close, but that's at least in part because I had to explain what is unusual about the situation, and because when commenting at this article for the first time I felt it particularly important to be completely open about my motivations and demonstrate good faith. When I said above that I agree with Woodwalker that was misleading because most people seem to have misunderstood Woodwalker. The point (of Woodwalker and me; I am not talking about the original poster of this section) is not to change the title of this article, hijack it for a different topic, or push a POV; the point is to
These two problems must be addressed because they make the article wrong. (I don't like to use "POV" in this context because there seems to be no real difference in POV between me and those who are responsible for this defect in the article.) Here are some of my key points again, in bullet form, and a few new ones:
Hans Adler 10:19, 5 December 2009 (UTC)
Misleading claim in first sentenceThe article's first sentence currently claims that "global warming" only refers to GW since the 20th century. This is not only false, I couldn't even find a source for this claim. For obvious reasons I am reluctant to add a fact tag to the first sentence, but I will do it if within a week or so the claim is still there and no adequate source for it has materialised. An adequate source for (formally) 'verifying' this claim would be a sufficiently reliable source that defines or at least uses "global warming" only in the restricted sense, even though it also discusses past or general GW or in other ways clearly operates in a sufficiently general context. Hans Adler 10:24, 5 December 2009 (UTC)
Yet another round of fiddling with the lede text will not solve anything.
You couldn't find a source for the fact that "global warming" refers to the modern period? How hard did you look? Try a dictionary, for example. As for scientific usage it's clear you have little familiarity with the relevant literature. Sure, if you dig hard enough you can find examples where "global warming" is used for other periods. But per WP:COMMONNAME that's not on. Short Brigade Harvester Boris (talk) 14:57, 5 December 2009 (UTC)

Let's face it, from a common-sense pov, global warming is when the world gets warmer and global cooling is when the world gets cooler. Just referring to the current episode as the ONLY example of global warming is, indeed, misleading, even if the current episode is more severe than past episodes. Also, nuclear winter, volcanic winter, ice ages, etc., could be considered periods of global cooling, and warm periods and thermal maxima could be considered periods of global warming. — Rickyrab | Talk 18:15, 13 December 2009 (UTC)

{Full disclosure: I first read this article about a month ago. My initial reaction was to look for a simpler graph (ie. one line of plotted data) that offered a more thorough perspective on the subject (I later learned there isn't really a 'simple way' to present much of this data). The chart I settled on was developed by a meteorologist and climatologist, but ultimately did not meet the article's standard of reference. Regulars may recall that discussion. I didn't consider it a big deal and I resumed my regular activities on Wikipedia.
But something about the article's presentation still nagged me. I came back and read it and reread it, and ultimately realized the scope of the 'controversy' surrounding global warming (as it's presented) is incredibly vague and hardly warrants much discussion (the 'Debate and skepticism' section appears to address 'global warming awareness' more than anything else). At the very least, it didn't seem to be what I would consider controversial. So I took it upon myself to research the subject to see how accurately it was being presented.
As it stands now, I've spent 82 hours of the past two weeks researching the material and the state of this article - reviewing past revisions, talk page archives, content forks, and relevant sources cited within. In truth, the deeper I found the rabbit hole went, the more I caught myself wishing I'd never even started the process to begin with (what with ignorance being bliss and all). :-)
I was two days into this process when the CRU email fiasco hit its stride in the news. Initially, I didn't consider it that significant, but like others, with time to digest it, I came to realize the magnitude of what it represented.
I'm not explaining all this to create some illusion of authority on the matter. I just want it to be understood that this was not a 'flyby' assessment intended to raise the hackles of those who have contributed heavily to the maintenance and upkeep of such a controversial article. Reviewing it was not a matter I took lightly. I consider my efforts in contributing to Wikipedia as not just a reflection of my own integrity, but the integrity of the the project as a whole. This represents the most time I've dedicated to a single subject here and when it's resolved, I'll be glad to get back to my regular, scatterbrained contributions elsewhere.}
All that being said, here is the summary of why I've concluded the article fails to meet Wikipedia's standard for neutrality:
If it's resolved that we intend to address the subject on the basis of current social perception (ie. the circumstances of the most recent warming trend as opposed to any period of warming in the climate record), then the entire scope of that perception must be addressed, including the dissenting view on AGW (anthropogenic global warming). The degree to which humans affect world climate is still under intense scrutiny and a matter of great debate in both the public sphere as well as scientific and scholarly circles. We have an intellectual responsibility to make this clear in the article. Yet even in the 'Debate and skepticism' section, mention is limited to a single sentence listing a few notable skeptics.
That relentless sockpuppetry has been employed in an effort to inject dissenting perspective into this article is certainly reprehensible. But it does not automatically invalidate the perspective or justify its ommission - content's veracity should not be judged solely on the methods employed in contributing it. Even good faith contributions to the article that shed light on the dissenting perspective are summarily dismissed (or quickly relegated to a POV fork) by finding some questionable aspect about the source so a policy for exclusion can be applied. But as questionable aspects of the currently accepted sources have come to light, this has become a bit of a double standard (ie. demanding 'peer-reviewed' sources when the possibility of subversion and manipulation of those sources has become evident). Nor is undue weight a valid reason for exclusion, as no weight whatsoever is given to the fact that there has been and still is heated debate over many assertions presented here.
In the lead, the IPCC's conclusions are issued with absolutely no mention of legitimate, significant concerns of reputable scientists and scholars regarding its data and assessments. While the IPCC report is important (as it represents work from a large segment of the climate change community), its assertions as to the degree of human influence on global climate should not be the only ones presented. It's important to remember that the IPCC is a heavily politicized force with a goal in presenting scientific data to provoke or influence action. It now exists to 'build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change'. Essentially, its purpose has become something more than simple scientific understanding (it could even be argued that it has an agenda). That does not mean the underlying data is necessarily wrong. Nor does it mean that its cause is not worthy. It simply warns us not to be so quick about addressing the subject through the filter of its conclusions alone. Legitimate concerns about its transparency and lack of peer-review have been voiced for years and the recent email fiasco simply serves to reinforce validity of that concern. The reality is that the science of global warming is still in its first generation of analysis. Addressing only the conclusions of a highly politicized report, regardless of its scope, simply cannot lend to neutral treatment of the subject.
A couple potential solutions that would help in resolving this:
1) Adjusting the lead to include a summary of the debate regarding anthropogenic influence on global warming with a corresponding passage appended to the Debate and skepticism section that goes into greater detail (and a serious review of the existing material in that section). Additionally, I would recommend inclusion of information relating to how the fossil fuel industry has conspired to manipulate debate on the matter as well.
or,
2) Removal of all 'conclusions' (and debate) from the lead. Including theories and assertions (consensus and otherwise) further along in the article would be reasonable, but should not be the lens through which we wholly assess (or summarize) it.
or,
3) Simply presenting the current state of global warming, explaining the science behind climate shifts and human interaction with them, and relegating all assertions, conclusions, debates, and criticism regarding AGW to related pages and/or a single page (ie. Anthropogenic Global Warming). This would be beneficial in reducing the number of 'Politics of global warming', 'Global Warming Controversy', 'Scientific opinion on climate change'-type articles on wikipedia (and there's alot of them) as they can all be summarized and addressed in a single article devoted to the majority opinion.
Of course, the latter two options would result in a sweeping restructure of the article and, given human inclination to avoid change, I defer to the first option as the most reasonable means of resolving the issue. Unfortunately, as mentioned earlier, even good faith efforts to incorporate critical evaluations of the IPCC conclusions have been summarily dismissed and frequently degenerate into edit-warring. Blithe disregard for a subject's reality deals as heavy a blow to Wikipedia's integrity as an article's manipulation by sockpuppets.
In conclusion, looking at the article overall, it's almost as if the maintenance has been overseen by editors so emotionally invested in remaining vigilant against persistent sockpuppetery that they lost objectivity. Ironically, as the puppetmaster tried harder and harder to incorporate his material, the article drifted further and further from his objective. It has left us in a situation where such a concerted effort has been made to actively suppress and sterilize any matter of dissent that the article has accumulated a half dozen POV forks and retained only a bunch of nonsensical, long-winded statements that are completely unrelated to any of the actual controversy or skepticism.
Input from uninvolved editors, especially those who are indifferent about the causes or mitigation of global warming, would be greatly appreciated (although the homework required for such an editor to properly assess the situation is pretty obscene).

If it's resolved that we intend to address the subject on the basis of current social perception - no, it isn't so resolved. I fear that your exteensive study has not resulted in much understanding.
It's important to remember that the IPCC is a heavily politicized force is just one of your many mistakes.
here is the summary of why I've concluded - it isn't clear why we should be so interested in your opinion. Everyone can comment, of course, but not everyone can post a vast long text as you've just done and expect people to read it all. I have a suggestion fro you: help keep the GW and related articles sane. Revert socks, don't support them on talk, and generally be helpful. Do this for a month or two, *then* come back with your opinions William M. Connolley (talk) 11:29, 5 December 2009 (UTC)
K10wnsta, thank you for all the time and thought you have put into improving this deeply flawed, disturbingly biased article. I concur with your approach to cleaning it up to conform with the high standards for neutrality at Wikipedia. Freedom Fan (talk) 16:56, 5 December 2009 (UTC)
<- While I'm sure that there are plenty of the scientists are acting out of a sense of duty, you can't deny that there are people who are on the AGW side for the cash they can milk out of it. World leaders haven't exactly been known for their selflessness, either. And there are scientists who are against AGW. But that's not really important. What is important is that when scientists disagree, they should provide their research that backs up their theories. Regardless of why they do their research, as long as they do it right, their research should benifit finding the final answer. As recent developments may or may not implicate the higher ups on the AGW side of cooking their data, the playing field may have leveled out a bit on whose research is or isn't viable. And this page only seems to display the pro-side research. At the least, it should have a part that discusses what dissenting scientists say, and what the pro side has done to debunk it. If the pro side's rebuttle is stronger, then it will only serve to strengthen their arguement. -Tainted Conformity Chat 00:33, 7 December 2009 (UTC)

ChyranandChloe, I apologize if I've annoyed you - that was not my intent. My specific suggestion would be to add a short paragraph towards the end of the Debate and skepticism section that briefly states what the incident is, links to the main article on it, and briefly summarizes what the best sources we can find have to say about its impact on the debate so far.
More generally, what I was hoping to get was an agreement in principle that the issue was within the scope of the article, and start a useful discussion of what the sources had to say about it. I must say that I do strongly disagree with the idea that leading newspapers such as the NYT and WP categorically fail as reliable sources - if nothing else, that seems to eliminate any objective common ground for determining when something has had an impact on the political debate (or, at least eliminate it until the issue shows up in Political Science theses ten years later).EastTN (talk) 16:00, 9 December 2009 (UTC)
I do not believe that there is any chance of neutrality per wikipedia definitions of neutrality in THIS article. Wikipedia rules do not exactly apply here.
Years ago, I came here without any specific agenda but just to improve the article if possible. I had no leaning one way or the other but I noticed that the definition in the first paragraph was (at least at that time) novel and unsupported by references. So I searched for references that defined the term "Global Warming" and suggested a summary that incorporated the vast bulk of those fully reliable sources' definitions. This was rejected despite wikipedia standards by a cadre editors who stand guard over the article. I was viewed as an enemy, insulted, called names and slandered.
And notice now the responses to requests for neutrality. For example, this very definition that I discussed, which (at least at the time that I researched it, was novel to wikipedia alone) is used as a defense of the content of the article: "I based that statement on ... primarily, the first sentence of the article ("increase in the average temperature ... since the mid-20th century ")" (Now I understand the resistance I got at the time, though it baffled me then).
Here is another perspective of an editor rejecting the wikipedia standards of neutrality: "This is not a 'debate' between two alternative sides. The two sides are those who understand the severity and urgency of the problem and those who don't." These are editors who are ignoring wikipedia standards of neutrality because they believe the issue is just too important. I can understand that sentiment... but it is not wikipedia standards.
And another: "Using newspaper coverage to argue for the modification of how an encyclopedia covers the science seems so misconceived to me that it's hard to take seriously. ... We don't, as a matter of fact, report on scientific matters using newspapers as sources. We're never going to do that." Notice... they will NEVER do that. Once again, wikipedia standards are considered ridiculous for this article and should be abandoned.
The protectors of this article find it impossible to imagine that if someone disagrees with their perspective, they are not somehow evil and need to be squelched. Good luck to anyone who tries to object. You will fail and you will find that it has nothing to do with wikipedia standards of neutrality. --Blue Tie (talk) 02:39, 13 December 2009 (UTC)

I have tried to put a little balance in the first paragraph of the Global Warming article. Anyone reading this would be left with the impression that AGW is a more solid scientific theory than Newton's Laws of Motion. I had added the following:
"However, a number of highly respected scientists dispute the consensus view. Recently, leaked emails reveal that the leading Global Warming scientists, at the Climatic Research Unit, University of East Anglia and elsewhere, have been concealing or altering the raw data, which shows the world has been cooling for the past decade. These Global Warming scientists have admitted in their emails, that none of the climate models can account for this lack of warming in the real world."
Not unsuprisingly, it was deleted a minute later. I note that despite the recent startling revelations of Climategate, this has completely failed to find any mention in the article. This strongly indicates censorship - since I am sure many editors must have tried to write about this highly relevant information.
I have asked for advice on how the editors controlling the article would recommend I rewrite these facts so that they wouldn't object to their inclusion. I received the following reply:
Please feel free to make any suggestions regarding balancing the first paragraph, so that the fact that many scientists dispute the AGW theory is mentioned. - Brittainia (talk) 12:37, 9 December 2009 (UTC)
We base everything in this article on the scientific perspecitve as reported in peer reviewed journals. Sm8900 had tried to change this consensus but he was unsuccessful. His Armada never made it to this article :) . Count Iblis (talk) 16:20, 9 December 2009 (UTC)
Getting this conversation back to my original point, is there any way to introduce some balance into the opening paragraph? I will accept that very current news needn't go here. But, the fact that there are many notable scientists who disagree with the consensus view does belong here to balance a certainty otherwise apparently stronger than both death and taxes.
How about the following at the end of the first paragraph: "However, a number of leading scientists dispute the consensus view. Recent climate data shows the world has not been warming for the past decade. Climate models cannot currently account for this lack of warming." - Brittainia (talk) 18:40, 9 December 2009 (UTC)
Well, I added that one small line back into the lede but as you can see, it was deleted within seconds:
So I guess that answers my original question. This was a lesson in the definition of "Censorship." - Brittainia (talk) 20:26, 9 December 2009 (UTC)
Scjessey, if you have a problem with the people included at List of scientists opposing the mainstream scientific assessment of global warming I suggest that you take that discussion to that page. As it pertains to this article, it would seem legitimate to have a single sentence in the lead that refers to that list. It purports to be a list of scientists and it's contents are closely monitored so if there are any inaccuracies there they are certainly minor for the purposes of our discussion relative to THIS article, and any corrections thereof should be made THERE not here. --GoRight (talk) 00:27, 10 December 2009 (UTC)
I feel that including this brief sentence in the lead section would not violate NPOV, and improves the article by giving both sides of a significant debate some basic coverage. --Steve, Sm8900 (talk) 17:47, 10 December 2009 (UTC)
The fact that "some" scientists dispute the idea that humans are causing the recent wave of global warming is about as relevant as the fact that "some" physicists reject the natural process of evolution. In other words, it's not relevant. The intro is fine and the article already has a skepiticism section at the end. It's not like we're hiding anything. We're saying it plainly: there are some notable people and scientists who disagree with the various ideas surrounding global warming. Should they be mentioned in the lead? No.UberCryxic (talk) 18:12, 13 December 2009 (UTC)

There is an article about the hacking of the Climatic Research Unit. As yet there seems to be no material effect on the science. This isn't surprising as climatology is a global field.
I added a 'missing info/climategate' tag to the Debate and skepticism section. I left a note to leave it up for 48 hours to reach a consensus to add text that mentions the climategate news.
OK. This text was deleted by tonysidaway 3 minutes after it was added by User:Brittainia;

Removed graph of sea level rise in the lead, this belongs in the section "Attributed and expected effects". There are two graphs on global temperatures, the first I believe are the mean temperature of each year with a step-wise (Dragonsflight? help me man) regression on it. The second compares the monthly average land-based and satellite based measurements with a linear regression through it all. I think we should cut the second, since it only goes back to 1975, where in the section "Temperature change" we start the regression in 1906. What do you guys think? ChyranandChloe (talk) 08:33, 13 December 2009 (UTC)
“ | Earth has experienced warming and cooling many times in the past. The recent Antarctic EPICA ice core spans 800,000 years, including eight glacial cycles timed by orbital variations with interglacial warm periods comparable to present temperatures.[2]
A rapid buildup of greenhouse gases caused warming in the early Jurassic period (about 180 million years ago), with average temperatures rising by 5 °C (9.0 °F). Research by the Open University indicates that the warming caused the rate of rock weathering to increase by 400%. As such weathering locks away carbon in calcite and dolomite, CO2 levels dropped back to normal over roughly the next 150,000 years.[3][4] Sudden releases of methane from clathrate compounds (the clathrate gun hypothesis) have been hypothesized as a cause for other warming events in the distant past, including the Permian-Triassic extinction event (about 251 million years ago) and the Paleocene-Eocene Thermal Maximum (about 55 million years ago). |

I think we're arguing about this diff . Whilst I don't care a lot about FA, I know some people do, and I wouldn't discount it entirely. It looks to me as though this argument has got heated, which is regrettable between two good contributors. I'd suggest reverting to the pre-change version (which I think means A's preferred version) and talk over what to do. But there is no hurry over this William M.
