List of...

Ron added the good ol' list of sci... . As has been said often before (usually to a chorus of yes-we-know-that) that page can't be used to assess scientific opinion, because it includes people who are clearly no longer scientist, and scientists with no climate expertise at all. Until that page gets cleaned up, leave it out of things like this William M. Connolley 19:41, 8 September 2007 (UTC)

William, I completely disagree. The list is a good list of scientists including many eminent who are "Professor Emeritus" of climate science. To say they are no longer scientists is just bogus. RonCram 04:37, 9 September 2007 (UTC)

This may be a bit not pc for some, but on the topic of Emeritus professor's views... A friend of mine studies physics and he mentioned that (he read it somewhere) in physics the new 'consensus' tends not to be established because scientists change their minds. It basically happens because all those that believed in the old stuff die. I thought it was funny. Brusegadi 04:42, 9 September 2007 (UTC)

Ron, I will revert your edit because the article you link to is not primarily about climate scientists. To be more precise, most of them are not either not climate scientists or not engaged in current research. Also, I think there is a thread about this in the archives. Brusegadi 04:48, 9 September 2007 (UTC)

Brusegadi, this article is about the controversy regarding the science. It is completely POV to give readers access to the majority view and not give access to skeptical scientists. The list of skeptical scientists includes both climate scientists and other types of geophysical scientists. It is not a list of social scientists or some other unrelated field. Give me the date of the archived discussion and I will read it.RonCram 05:14, 9 September 2007 (UTC)

Ron, just a question -- do you know what "emeritus" means? Raymond Arritt 05:26, 9 September 2007 (UTC)

Raymond, you really need to stop treating me as if I am uneducated. Maybe I am just in a bad mood tonight, but I am beginning to find your questions offensive. Of course I know what "emeritus" means - not every retired prof is given the status of "emeritus." This is a title of honor and usually means the prof still keeps an office at the university, at least the ones I knew did, even though they do not have any teaching responsibilities. These older gents have tons of wisdom and are often asked to attend meetings with contributors to the university. BTW, instead of insulting me with these silly questions, you ought to start paying me for all the things I have taught you. Without me you would not know about the data archiving policies of AGU - or how the distribution of weather stations could yield a non-warming trend overall but still show a warming trend using the grid cell method. RonCram 06:11, 9 September 2007 (UTC)

No. The practice varies, but at most universities "emeritus" simply means retired after a certain minimum period of service. It's not usually a "title of honor" as you say. Raymond Arritt 13:36, 10 September 2007 (UTC)

Raymond, that is nonsense. I defy you to name me one university (in the U.S.) that has such a practice. RonCram 23:01, 25 September 2007 (UTC)

If you look under emeritus here you will see that it does not say anything about "achievements" and that the title is "customarily awarded" to faculty that is retiring after 15 years of service. You do not have to be a full professor so associates may get it too. Finally, right under "18.4 Retired Faculty" emeritus is used interchangeably with "retired faculty." What I did not know is that it could also be awarded to people doing mostly administrative work. For those of you who like to learn about places other than the United States, Cambridge has definitions for some slang terms they use; including one that seems right on for this "argument." Brusegadi 23:45, 25 September 2007 (UTC)

Bellamy is no longer a scientist, not because he's emeritus, but because he has switched to PR. But also, the list contains many scientists with no climate expertise, and hence doesn't belong under the heading "sci cons" William M. Connolley 13:15, 10 September 2007 (UTC)

Hansen "frees the code"

Stephen McIntyre announced that Hansen has finally released the code. McIntyre has been requesting the source code used to construct global temps from GISS for some time. Contrary to the standards of science (see Pseudoscience), Hansen had refused to release the code until now. Without doubt, the fact GISS had to admit McIntyre found an error put additional pressure on GISS to release the code. This is a significant development in the controversy. It will give McIntyre more information and many people expect more errors to be found. While Hansen's action is a step forward, Phil Jones of CRU still does not share data and code and so this will continue to be a controversial issue. The article does not deal with it in any way at this point and it needs to. RonCram 06:11, 9 September 2007 (UTC)

You can write about it in the article about Stephen McIntyre, or you could create a new article devoted to the dispute McIntyre has with Hansen about the data. It seems to be a notable thing in the climate-skeptic sector of the blogosphere. In this article we cannot give too much weight on the opinions of one person (but it can be mentioned briefly). Count Iblis 13:40, 9 September 2007 (UTC)

I imagine a brief bit might be appropriate in the James Hansen article, as well. Of course, due care must be taken to keep it NPOV. Ben Hocking 12:25, 10 September 2007 (UTC)

General comment

It's been a while since I read this whole article from beginning to end. I'd not realized how awful it is. Raymond Arritt 23:14, 9 September 2007 (UTC)

Raymond, I agree with that. I would much rather see the political stuff merged into the Politics of global warming article. If we focused just on the science controversy, it could be turned into a decent article. RonCram 01:08, 10 September 2007 (UTC)

That would be good for a start. Raymond Arritt 01:10, 10 September 2007 (UTC)

I do not know anything about merging articles or portions of articles. Is it a long process? RonCram 02:13, 10 September 2007 (UTC)

Sadly so, its a bit of a free for all. I've just improved it a bit :-) William M. Connolley 13:17, 10 September 2007 (UTC)

America COMPETES Act

Someone requested more info about the provision of this act requiring government scientists to provide data and methods. Here's a quote from the Act:

SEC. 1009. RELEASE OF SCIENTIFIC RESEARCH RESULTS.

(a) Principles- Not later than 90 days after the date of the enactment of this Act, the Director of the Office of Science and Technology Policy, in consultation with the Director of the Office of Management and Budget and the heads of all Federal civilian agencies that conduct scientific research, shall develop and issue an overarching set of principles to ensure the communication and open exchange of data and results to other agencies, policymakers, and the public of research conducted by a scientist employed by a Federal civilian agency and to prevent the intentional or unintentional suppression or distortion of such research findings. The principles shall encourage the open exchange of data and results of research undertaken by a scientist employed by such an agency and shall be consistent with existing Federal laws, including chapter 18 of title 35, United States Code (commonly known as the `Bayh-Dole Act’). The principles shall also take into consideration the policies of peer-reviewed scientific journals in which Federal scientists may currently publish results. (page 11 of 208 of the Act)

BTW, COMPETES is capitalized because it is an acronym for "Creating Opportunities to Meaningfully Promote Excellence in Technology, Education, and Science." RonCram 14:35, 10 September 2007 (UTC)

It's not an acronym, but a propagandistic backronym ;-). Anyways, it looks like this is mostly hot air. Note "overarching principle" (i.e. nothing concrete), "encourage the open exchange" (i.e. not require it). It also only applies to federal research agencies. I welcome the sentiment, but I doubt the effect. I fear this will add another bureaucratic layer and have the opposite effect ("before you publish, it has to be vetted by our open access officer. Oh, for vetting that incenvenient piece of research he will have time in 2013, unless his dentist's appointment gets into the way"). But maybe I'm just cynical. --Stephan Schulz 14:52, 10 September 2007 (UTC)

To me this looks more significant a provision than you acknowledge. As an authority-giving clause, this means that principles will be developped and issued, and that these principles will have to require the open exchange of data and results. The language is quite clear despite some appearance of looseness. It actually looks like after Enron - the SEC was 'invited' to develop regulations that would 'encourage' some practices... This translated into SOX. --Childhood's End 15:48, 10 September 2007 (UTC)

I notice that William has removed the section on data archiving and sharing saying that it is not a major part of the controversy, only my pet. This is not true. Congress had to request Michael Mann to testify and turn over all of his records before they could get information that should have been turned over previously. Congress also passed the America COMPETES Act setting up a process requiring government scientists to archive and share data. If it is a big enough deal for Congress to get involved, then it is a big deal. I know it is an embarrassment to William and his friends, but facts are facts. Refusal to turn over data and methods is not right. This is a major part of the controversy. If they would turn over the data and methods, maybe the skeptics would be convinced. They will never be convinced without it. It would contrary to science to be convinced without seeing the data and methods. RonCram 17:47, 10 September 2007 (UTC)

Ron, you're ranting again. And no, glaciers *don't* break off and form sea ice William M. Connolley 18:13, 10 September 2007 (UTC)

William, you are being insulting. If you are trying to make me think you are delusional, it is not working. I did not say sea ice breaks off to form glaciers, glaciers break off and become sea ice. One of the news articles you deleted was about Greenland's glaciers and they do break off into the sea. RonCram 18:21, 10 September 2007 (UTC)

?!?Wot are you on?!? Where does sea ice breaks off to form glaciers come from? And no, glaciers don't break off to become sea ice, which is what I criticised you for. Glaciers break off into the sea - buts that a different matter William M. Connolley 19:00, 10 September 2007 (UTC)

I must say that imo, once this issue deserved Congress attention, it certainly became more relevant and of the essence of the Global warming controversy than betting over global warming or passive smoking... --Childhood's End 19:24, 10 September 2007 (UTC)

Lindzen funding sources

Recently this was deleted:

as well as funding from federal sources including the National Science Foundation, the ], and ].<ref>{{cite journal | url=http://www-eaps.mit.edu/faculty/lindzen/203_2001GL014074.pdf | title=Reconciling observations of global temperature change | last=Lindzen | first=Richard S. | authorlink=Richard S.

A request was made to bring to the talk page for re-adding (actually, it should have been brought to the talk page before deleting, but I have no interest in an edit-war), so I'm doing so. The claim was that it wasn't clear that the source backed up the claim, but if you look at the acknowledgments on the last page, it clearly says:

This work was supported by grants ATM9813795 from the National Science Foundation, DEFG02-93ER61673 from the Department of Energy, and NAG5-5147 from National Aeronautics and Space Administration.

I feel that this supports the sentence quite amply. Thoughts? Ben Hocking 21:23, 10 September 2007 (UTC)

Agreed. The user may have skimmed over it too fast and not noticed it. Brusegadi 21:34, 10 September 2007 (UTC)

Pielke and sea ice

Ron insists on re-inserting an edit that looks barking to me: "arctic sea ice is approaching its record low, but its current level is within natural climate variability". First, Pielke doesn't say "within natural climate variability" or indeed anything very similar to it, AFAICS. Second, Pielkes original post was on the 10th of Aug and can (just about) be excused noticing that the very data he was relying on said it was already a minimum. But now the ice has declined even further, there is no doubt that "is approaching" is simply wrong: it *is* a record low. We don't have to print everything RP says, especially when its obviously false. RP knows precious little about sea ice, as evidenced by his "Antarctic" comments in the same post William M. Connolley 21:37, 10 September 2007 (UTC)

I second that. If the record low is an outlier then being close to the record does not imply being within natural variability. Including it constitutes WP:OR. Furthermore, if we already have a new record-low inclusion of that paragraph is not correct, as William Connolley points out. Ciao, Brusegadi 21:41, 10 September 2007 (UTC)

William, Pielke makes clear from his post that he prefers the site you linked to because it is updated daily. Your conclusion that Pielke would write about a daily website without looking at it for two days seems ridiculous to me. There is no question Pielke has read it just prior to his post because he is talking about the news media picking up the story soon. Pielke does indicate that sea ice will continue to shrink since it is still summer and he provides a link to another website which is updated weekly. The NSIDC website says the previous record was set in 2005. If the article says sea ice has reached a record low, it also needs to mention when records began to be kept so readers will know these types of measurements were not made in the 1930s. Pielke's view that sea ice low is due to regional warming and not global warming is a common view among skeptics, including Syun-Ichi Akasofu - the founding director of the International Arctic Research Center. I used Pielke's quote because it is more recent and directly applicable to the current situation. RonCram 04:31, 11 September 2007 (UTC)

Still makes no sense at all. Pielke is getting data from his preferred site, which says that sea ice has just reached a record low, and you insist he knew that, and he writes a post saying "approaching a record low"? Its obviously wrong. We could perhaps put it on the Pielke page as an example of his errors; but there is no point putting it in here. I notice you haven't troubled to defend your inventing of the stuff about within natural variability William M. Connolley 08:28, 11 September 2007 (UTC)

No, William, it is not obviously wrong. The data from Cryosphere Today is great data, but the data only goes back a short time. They did not take those measurements in the 1930s when the previous low happened. Pielke is also exactly right about the question of arctic sea ice melt being from regional or global warming. I have referenced the images from Cryosphere Today he used for Southern Hemisphere. In addition, I referenced a Letter to Nature that points out the high natural variability of arctic sea ice and how changes there do not conform to expectations of global warming. Since this article is about the science controversy, it is important these views are made available to readers. RonCram 13:58, 14 September 2007 (UTC)

Ignoring for a moment your WP:OR regarding 1930 (which neither Pielke nor anyone else but you mention). Where do you get the information that the 1930s should be the "previous low"? (Chapman and Walsh(1993) as well as Vinnikov et al(1999) seem to disagree .... a lot). --Kim D. Petersen 21:19, 14 September 2007 (UTC)

I have not read the Vinnikov paper but I know that 1934 was the warmest year in the U.S. in the 20th century. 1934 was also the warmest year in Europe, if you only count the rural stations. 1934 does not show to be the warmest in Russia, but the Russian temp histories are not reliable. To reach a record low in sea ice melt, you need warm temperatures and you need the arctic to be in a warm period of its 8-10 oscillation. Since the entire decade of the 1930s was warm, one of those years had to be in the warm period of the regional oscillation. I think it is clear from Pielke's writings that he is aware of some measure of sea ice that showed it to be quite low in the 1930s. I do not know what measurement that could be. Obviously, it is not the satellite method currently being used. RonCram 23:57, 24 September 2007 (UTC)

Laxon et al.

As far as i can see the insertion of a paper by Laxon et al(2003), is misrepresenting the results of the paper (by cherry-picking a quote):

However, researchers claim computer models predictions poorly represent observed changes in arctic sea ice.

'The observed variability of Arctic sea ice thickness, which shows that the sea ice mass can change by up to 16% within one year, contrasts with the concept of a slowly dwindling ice pack, produced by greenhouse warming.

This makes us think that Laxon et al are arguing against the previous paragraph, which as far as i can see is entirely wrong. If i read the paper correctly - then Laxon et al. are arguing that the melt is being underestimated by models (corresponding well with the former paragraph) - not that it is being overestimated as the text implies. (i'm btw. a bit confused about what this is doing here - since it seems more appropriate elsewhere - and looks to me to be an "invented" controversy). --Kim D. Petersen 14:08, 14 September 2007 (UTC)

Kim, you seem to be confused by many things. If you read the paper in its entirety, you would the authors are convinced the arctic sea ice melt is not related to global warming but to natural climate variability, including sometimes longer summer seasons. They see an eight year oscillation between longer and shorter summer melt seasons and they also see a much greater variability in arctic sea ice on an annual basis than the computer models show. This is further support of Pielke's position that arctic sea ice melt is related to regional warming and not global warming. Pielke's comments continue to be germane to this aspect of the scientific controversy. If you still want to delete this section, I suggest you try WP:IDONTLIKEIT. RonCram 14:32, 14 September 2007 (UTC)

Instead, how about a short summary in the style of "However, in light of recent studies and observations made in Antartica, some scientists argue that Arctic ice melting is attributable to regional warming instead of global warming (refs)" ? --Childhood's End 14:37, 14 September 2007 (UTC)

That would implicitely accept a broken use of language. Global warming and local warming don't conflict, one is an expression of the other. I could just as well claim that the "arctic sea ice is not melting, just some chunks of ice swimming in the arctic ocean". --Stephan Schulz 14:55, 14 September 2007 (UTC)

You can obviously have ice melting because the region has warmed without it being a consequence of planetary warming.... That does not mean that global warming and regional warming are conflicting. --Childhood's End 15:15, 14 September 2007 (UTC)

I'm confused here, where exactly does the Laxon paper argue against global warming or argue for local variability? It actually does the opposite. Its stating that the circulation issues have little effect - and (again from my reading) that the GCM's are understating the consequences in loss of sea-ice. The actual cherry-picked quote is even further misrepresenting since the current melt is way beyond 16% (annual variation) - since its currently more than 20% below the last record.... --Kim D. Petersen 15:24, 14 September 2007 (UTC)

You should read my proposal as "Provided Ron is right"... But at least Pielke seems to make the suggestion no? --Childhood's End 15:58, 14 September 2007 (UTC)

Ron misrepresents the paper; if we could stop to talk about it he might learn but I don't have high hopes. Peilkes views are simply silly in this instance. Things don't belong just because Pielke says them - this article is about the controversy in general. You need more people saying this wacko stuff, *then* it can go in. This is "depresys" Smith, BTW William M. Connolley 20:52, 14 September 2007 (UTC)

William, I resent you saying I am misrepresenting the paper. Nothing could be further from the truth. All of my statements have been accurate. Laxon, Peacock and Smith write: "However, it is unclear from model results whether ice thickness is controlled mainly by changes in thermodynamic (radiative or thermal) forcing5, or by dynamic (ocean and wind stress) forcing7." Thermodynamic forcings may be global but dynamic forcings are more closely related to regional climate. They also write: "The majority of Arctic Ocean models suggest that variability in Arctic ice thickness occurs on decadal timescales5,6,9, and is caused mainly by dynamic forcing6–8." They write: "However, numerical simulations of ice thickness are undermined by uncertainties in the representation of physical processes9, and by differences in methods used to couple the ice, ocean and atmosphere12, resulting in significant discrepancies between model simulations of ice thickness evolution14." Here they admit the models are not very good. They also write: "The lack of continuous large-scale thickness measurements means that conclusions drawn from numerical simulations regarding the variability of Arctic sea ice thickness, and the processes that control it, remain untested3,12." Here they admit that we simply do not have much data about sea ice in the past. Pielke writes that we are "approaching" record lows and he must have a reason for his view. No doubt Pielke has the 1930s in view as the time period of the previous low but satellite records were not kept at that time. To make a big deal out of the current level of sea ice is unscientific. We do not have enough data to make claims about record lows in arctic sea ice. RonCram 19:07, 24 September 2007 (UTC)

Resent all you like, it doesn't change your inability to learn, though your ablilty to read Pielkes mind is impressive. But I agree, making a big deal of the current Arctic sea ice is a bad idea - see the current t:GW or indeed http://scienceblogs.com/stoat/2007/09/betting_on_sea_ice.php William M. Connolley 21:56, 24 September 2007 (UTC)

William, you are just being pejorative. You did not attempt to deal with any of the facts I presented so you did not support your claim regarding my "inability to learn." I accurately represented the paper which shows the authors are not convinced the level of sea ice is related to global warming. Your blog link does not really deal with issue of regional vs. global warming. You only project that next year will not set a new record. It seems a safe bet to me. Let me know if you get any takers. RonCram 23:13, 24 September 2007 (UTC)

For more on arctic ice in the 1930s, you can visit the Arctic Warming website that summarizes a number of research papers. See specifically this. It is pretty clear that arctic warming and sea ice melt has considerable natural variability. RonCram 13:56, 25 September 2007 (UTC)

World Conference on Research Integrity to Foster Responsible Research

European Science Foundation has reported on the "World Conference on Research Integrity" which met in Portugal from Sep 16-19. It was organized by the ESF and the U.S. Office of Research Integrity. They discussed two incidents touching on global warming - the misrepresentation of the examination of station history in China and the NASA error found by Steve McIntyre. The misrepresentation regarding Chinese station histories is an issue being pushed by Doug Keenan. Keenan has accused Wang, a co-author of Phil Jones, of unethical behavior. Both of these issues were originally raised by Steve McIntyre. It seems misconduct by climatologists to push an alarmist view of global warming is becoming a more important issue all the time. The article should discuss this. RonCram 17:46, 24 September 2007 (UTC)

Happens where you least expect it. Brusegadi 20:23, 24 September 2007 (UTC)

Brusegadi, climate science is a field with one of the worst reputations regarding unethical behavior by scientists. This is mainly due to their refusal to provide data, methods and code so other researchers can reproduce their work. Almost whenever this info is provided, errors both intentional and unintentional are found. Lindzen is correct to be negative about the state of affairs in climate science. RonCram 21:25, 24 September 2007 (UTC)

That's funny... a few years back it was secondhand-smoke researchers who, we were told, had a horrible reputation for unethically bending the data to support their "alarmist" views on the harms of passive smoking (cf. anything by Steven Milloy). Now it looks like climate scientists have surpassed even that ethical low point (cf., well, anything by Steven Milloy). It's almost like there's a pattern er something... though I'm sure more study would be needed to establish one. MastCell 21:35, 24 September 2007 (UTC) Never mind... that was probably better kept to myself. MastCell 21:36, 24 September 2007 (UTC)

Oh dear, I wish you hadn't done that... now I feel obliged to ask Ron to stop ranting, again. Ron, please see WP:SOAP and try to use the talk to discuss improvements to the article William M. Connolley 21:53, 24 September 2007 (UTC)

Sorry, the substance: why should this article discuss the conf? According to their prog they have nothing to say about climate, but a lot to say about medical. Why not try over there? William M. Connolley 21:58, 24 September 2007 (UTC)

William, if you read the article I linked to, you would see that climate issues were discussed just as I wrote. My earlier comment was a response to Brusegadi since he seemed to think that climate science was a rare place to find unethical behavior. The two fields with these greatest number of these kinds of problems seem to be medicine and climate. My post is all about making the article better. Unethical behavior is a major part of this controversy. RonCram 22:36, 24 September 2007 (UTC)

William, Howard Alper specifically pointed to medicine and climate science as fields with ethical issues. I have to agree with him. RonCram 23:04, 24 September 2007 (UTC)

Predictions of global warming are not based on scientific forecasting

J. Scott Armstrong has presented on this issue. I just recently found his presentation online. The PowerPoint (in pdf form) is here. Video of him making the presentation is here. Armstrong audited IPCC chapter 8 and found 72 principles of scientific forecasting were violated. I believe this was discussed here before. Why is it not in the article? If there was a reason, I have forgotten. RonCram 23:34, 24 September 2007 (UTC)

I agree this is an extremely important criticism of the IPCC methodology. Further coverage here

If I can point to him again, David Orrell makes a similar claim, and few would say he's not an authority in this regard. You can take a glimpse at . --Childhood's End 17:29, 25 September 2007 (UTC)

Margaret Thatcher, Miner's Strike, Nuclear Power, Global Warming

Margaret Thatcher's initial interest in Carbon Dioxide emissions (and eventually, Global Warming) was motivated by long-term strategic concerns for British Capitalism - in particular, energy stability following the miner's strike of the mid-1980's - and NOT by concerns for the environment. Stimulating public concerns around atmospheric pollution was seen as the key to her pro-nuclear policies - which was to be promoted as a clean alternative to energy production which was heavily reliant on burning fossil fuels.

I believe this important point should be included as context to Margaret Thatcher's 'interest' in global warming mentioned at the beginning of this article.BadCop666 07:35, 25 September 2007 (UTC)

Sounds good. Given Thatcher's reputation, the above makes sense to me; but for the sake of verifiability do not forget the sources. Take care, Brusegadi 07:41, 25 September 2007 (UTC)

Jim Hansen's earlier prediction of coming Ice Age

Interesting opinion piece in the Investor's Business Daily based on a story in the Washington Post in 1971. Recently, global warming alarmists have tried to distance themselves from the prediction of a coming Ice Age back in the 70s. But it is hard to distance your camp when one of the leaders of the current alarmism was a leader of the Ice Age alarmism. I think this deserves to be in the article. RonCram 13:19, 25 September 2007 (UTC)

See talk:James Hansen and try to centralize the discussion in one place, please. --Stephan Schulz 13:58, 25 September 2007 (UTC)

Stephan, I do not see the point in that. This is relevant to both articles. Different editors are involved in the two articles. Everyone should be involved in the discussion. RonCram 14:28, 25 September 2007 (UTC)

And they can now all go over to talk:James Hansen so that we do not need to copy and paste the same arguments all over the place. --Stephan Schulz 14:34, 25 September 2007 (UTC)

Like I said, Stephan, your request is nonsensical. Arguments (reasons for inclusion or exclusion) will differ depending on the article. Each article has its own discussion page for a reason. RonCram 18:04, 25 September 2007 (UTC)

That is sound reasoning in general. In this particular case, however, the source you cite is simply wrong, as explained at Talk:James Hansen. An unreliable source has no place in either article. --Stephan Schulz 18:55, 25 September 2007 (UTC)

If the argument was about weight or relevance, you'd have a point Ron. However, that article is inaccurate as the talk page on James Hansen's page shows. There's no point in having two separate discussions about the accuracy of the claim. It's either accurate or it's not (it's not), irrespective of which article we're talking about.

Okay, so your real argument (for both Stephan and Benhocking) is that this published (and reliable) source is wrong and you do not want to have to explain this on both pages. At least now you have explained your reasoning. But your reasoning is still not valid because it has to be explained to two separate groups of editors. After a quick glance through the Talk page on James Hansen, I am not convinced the published source is wrong. It may be possible to convince me, but it has not happened yet.

Both sets of editors can go read it over there. Surprisingly, you don't need a permit to read other than your normal pages on Misplaced Pages. And I suggest you take more than a "quick glance" over there and read how your obviously unreliable (why am I even discussing this? It's an editorial by someone who has not an inkling of science) fourth-hand source mangles the third-hand source (a recent Washington Times article) until it is unrecognizable. You can than see how the third-hand source misrepresents the second hand source in various ways, but in particular by omitting that Hansen's program was not a climate program, but a program that simulated how aerosols shatter sunlight (and developed for the analysis of clouds on Venus). The second-hand source, this 1971 Washington Post article describes this reasonably well, but of course oversimplifies the first-hand Science paper. --Stephan Schulz 23:42, 25 September 2007 (UTC)
