Q1: Is there really a scientific consensus on climate change? A1: Yes. The IPCC findings of recent warming as a result of human influence are explicitly recognized as the "consensus" scientific view by the science academies of all the major industrialized countries. No scientific body of national or international standing presently rejects the basic findings of human influence on recent climate. This scientific consensus is supported by over 99% of publishing climate scientists. See also: Scientific consensus on climate change Q2: How can we say climate change is real when it's been so cold in such-and-such a place? A2: This is why it is termed "global warming", not "(such-and-such a place) warming". Even then, what rises is the average temperature over time – that is, the temperature will fluctuate up and down within the overall rising trend. To give an idea of the relevant time scales, the standard averaging period specified by the World Meteorological Organisation (WMO) is 30 years. Accordingly, the WMO defines climate change as "a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer)." Q3: Can't the increase of CO2 be from natural sources, like volcanoes or the oceans? A3: While these claims are popular among global warming skeptics, including academically trained ones, they are incorrect. This is known from any of several perspectives:
  • Current human emissions of CO2 are at least 100 times larger than volcanic emissions. Measurements of CO2 levels over the past 50 years do not show any significant rises after eruptions. This is easily seen in a graph of CO2 concentrations over the past 50 years: the strongest eruption during the period, that of Mount Pinatubo in 1991, produced no increase in the trend.
  • Isotopic analysis of atmospheric carbon dioxide shows the observed change in the ratio of carbon isotopes reflects the isotopic ratios in fossil fuels.
  • Atmospheric oxygen content is decreasing at a rate that agrees with the amount of oxygen being used to burn fossil fuels.
  • If the oceans were giving up some of their carbon dioxide, their carbon dioxide concentration would have to decrease. But instead we are measuring an increase in the oceans' carbon dioxide concentration, resulting in the oceans becoming more acidic (or in other words, less basic).
Q4: I think the article is missing some things, or has some things wrong. Can I change it? A4: Yes. Keep in mind that your points need to be based on documented evidence from the peer-reviewed literature, or other information that meets standards of verifiability, reliability, and no original research. If you do not have such evidence, more experienced editors may be able to help you find it (or confirm that such evidence does not exist). You are welcome to make such queries on the article's talk page but please keep in mind that the talk page is for discussing improvements to the article, not discussing the topic. There are many forums that welcome general discussions of global warming, but the article talk page is not such a forum. Q5: Why haven't the graphs been updated? A5: Two reasons:
  • There are many images used in the articles related to global warming, and there are many reasons why they may not be updated with the latest data. Some of the figures, like the Global Warming Map, are static, meaning that they are intended to show a particular phenomenon and are not meant to be updated frequently or at all. Others, like the Instrumental Temperature Record and Northern Hemisphere Sea Ice Extent Anomalies, use yearly data and thus are updated once per year—usually in mid- to late-January, depending upon when the data is publicly released, and when a volunteer creates the image. Still others, like Mauna Loa Carbon Dioxide, use monthly data. These are updated semi-regularly.
  • However, just because an image is 6 months or a year old does not mean it is useless. Robert A. Heinlein is credited with saying, "Climate is what you expect, weather is what you get", meaning that climate is defined as a long-term average of weather, usually about 30 years. This length was chosen to eliminate the year-to-year variations. Thus, in terms of climate change, any given year's data is of little import.
Q6: Isn't climate change "just a theory"? A6: People who say this are abusing the word "theory" by conflating its common meaning with its scientific meaning. In common usage, "theory" can mean a hunch or guess, but a scientific theory, roughly speaking, means a coherent set of explanations that is compatible with observations and that allows predictions to be made. That the temperature is rising is an observation. An explanation for this (also known as a hypothesis) is that the warming is primarily driven by greenhouse gases (such as CO2 and methane) released into the atmosphere by human activity. Scientific models have been built that predict the rise in temperature and these predictions have matched observations. When scientists gain confidence in a hypothesis because it matches observation and has survived intense scrutiny, the hypothesis may be called a "theory". Strictly speaking, scientific theories are never proven, but the degree of confidence in a theory can be discussed. The scientific models now suggest that it is "extremely likely" (>95%) to "virtually certain" (>99%) that the increases in temperature have been caused by human activity as discussed in the IPCC Fifth Assessment Report. Global warming via greenhouse gases by human activity is a theory (in the scientific sense), but it is most definitely not just a hunch or guess. Q7: Does methane cause more warming than CO2? A7: It's true that methane is more potent molecule for molecule. But there's far less of it in the atmosphere, so the total effect is smaller. The atmospheric lifetime of methane (about 10 years) is a lot shorter than that of CO2 (hundreds to thousands of years), so when methane emissions are reduced the concentration in the atmosphere soon falls, whereas CO2 accumulates in the atmosphere over long periods. For details see the greenhouse gas and global warming potential articles. See also: Clathrate gun hypothesis and Arctic methane release Q8: How can you say there's a consensus when lists of "skeptical scientists" have been compiled? A8: Consensus is not the same as unanimity, the latter of which is impractical for large groups. Over 99% of publishing climate scientists agree on anthropogenic climate change. This is an extremely high percentage well past any reasonable threshold for consensus. Any list of "skeptical scientists" would be dwarfed by a comparably compiled list of scientists accepting anthropogenic climate change. Q9: Did climate change end in 1998? A9: One of the strongest El Niño events in the instrumental record occurred during late 1997 through 1998, causing a spike in global temperature for 1998. Through the mid-late 2000s this abnormally warm year could be chosen as the starting point for comparisons with later years in order to produce a cooling trend; choosing any other year in the 20th century produced a warming trend. This no longer holds since the mean global temperatures in 2005, 2010, 2014, 2015 and 2016 have all been warmer than 1998. More importantly, scientists do not define a "trend" by looking at the difference between two given years. Instead they use methods such as linear regression that take into account all the values in a series of data. The World Meteorological Organisation specifies 30 years as the standard averaging period for climate statistics so that year-to-year fluctuations are averaged out; thus, 10 years isn't long enough to detect a climate trend. Q10: Wasn't Greenland much warmer during the period of Norse settlement? A10: Some people assume this because of the island's name. In fact the Saga of Erik the Red tells us Erik named the new colony Greenland because "men will desire much the more to go there if the land has a good name." Advertising hype was alive and well in 985 AD.

While much of Greenland was and remains under a large ice sheet, the areas of Greenland that were settled by the Norse were coastal areas with fjords that, to this day, remain quite green. You can see the following images for reference:

Q11: Are the IPCC reports prepared by biased UN scientists? A11: The IPCC reports are not produced by "UN scientists". The IPCC does not employ the scientists who generate the reports, and it has no control over them. The scientists are internationally recognized experts, most with a long history of successful research in the field. They are employed by various organizations including scientific research institutes, agencies like NASA and NOAA, and universities. They receive no extra pay for their participation in the IPCC process, which is considered a normal part of their academic duties. Q12: Hasn't global sea ice increased over the last 30 years? A12: Measurements show that it has not. Claims that global sea ice amounts have stayed the same or increased are a result of cherry picking two data points to compare, while ignoring the real (strongly statistically significant) downward trend in measurements of global sea ice amounts.

Arctic sea ice cover is declining strongly; Antarctic sea ice cover has had some much smaller increases, though it may or may not be thinning, and the Southern Ocean is warming. The net global ice-cover trend is clearly downwards.

See also: Arctic sea ice decline See also: Antarctic sea ice § Recent trends and climate change Q13: Weren't scientists telling us in the 1970s that the Earth was cooling instead of warming? A13: They weren't – see the article on global cooling. An article in the Bulletin of the American Meteorological Society has reviewed the scientific literature at that time and found that even during the 1970s the prevailing scientific concern was over warming. The common misperception that cooling was the main concern during the 1970s arose from a few studies that were sensationalized in the popular press, such as a short nine-paragraph article that appeared in Newsweek in 1975. (Newsweek eventually apologized for having misrepresented the state of the science in the 1970s.) The author of that article has repudiated the idea that it should be used to deny global warming. Q14: Doesn't water vapour cause 98% of the greenhouse effect? A14: Water vapour is indeed a major greenhouse gas, contributing about 36% to 70% (not 98%) of the total greenhouse effect. But water vapour has a very short atmospheric lifetime (about 10 days), compared with decades to centuries for greenhouse gases like CO2 or nitrous oxide. As a result it is very nearly in a dynamic equilibrium in the atmosphere, which globally maintains a nearly constant relative humidity. In simpler terms, any excess water vapour is removed by rainfall, and any deficit of water vapour is replenished by evaporation from the Earth's surface, which literally has oceans of water. Thus water vapour cannot act as a driver of climate change.

Rising temperatures caused by the long-lived greenhouse gases will however allow the atmosphere to hold more vapour. This will lead to an increase in the absolute amount of water vapour in the atmosphere. Since water vapour is itself a greenhouse gas, this is an example of a positive feedback. Thus, whereas water vapour is not a driver of climate change, it amplifies existing trends.

See also: Greenhouse gas and Greenhouse effect Q15: Is the fact that other solar system bodies are warming evidence for a common cause (i.e. the sun)? A15: While some solar system bodies show evidence of local or global climate change, there is no evidence for a common cause of warming.
  • A 2007 National Geographic article described the views of Khabibullo Abdusamatov, who claims that the sun is responsible for global warming on both Earth and Mars. Abdussamatov's views have no support in the scientific community, as the second page of the National Geographic article makes clear: "'His views are completely at odds with the mainstream scientific opinion,' said Colin Wilson, a planetary physicist at England's Oxford University. Amato Evan, a climate scientist at the University of Wisconsin, Madison, added that 'the idea just isn't supported by the theory or by the observations.'"
  • There is no reliable source claiming that Jupiter is warming. However, observations of the Red Spot Jr. storm suggest Jupiter could be in a period of global climate change. This is hypothesized to be part of an approximately 70 year global climate cycle, characterized by the relatively rapid forming and subsequent slow erosion and merging of cyclonic and anticyclonic vortices that help transfer heat between Jupiter's poles and equator. The cycle works like this: As the vortices erode, heat exchange is reduced; this makes the poles cool down and the equatorial region heat up; the resulting temperature difference destabilizes the atmosphere, leading to the creation of new vortices.
  • Pluto has an extremely elliptical orbit with a period of about 248 years. Data are sparse, but two data points from 1988 and 2002 indirectly suggest that Pluto warmed between those two dates. Pluto's temperature is heavily influenced by its elliptical orbit – it was closest to the sun in 1989 and has slowly receded since. Because of thermal inertia, it is expected to warm for a while after it passes perihelion (similar to how a sunny day's warmest temperatures happen during the afternoon instead of right at noon). No other mechanism has so far been seriously suggested. Here is a reasonable summary, and this paper discusses how the thermal inertia is provided by sublimation and evaporation of parts of Pluto's atmosphere. A more popular account is here and in Misplaced Pages's own article.
See also: Climate of Mars and Extraterrestrial atmosphere Q16: Do scientists support climate change just to get more money? A16: No,
  • Scientists participate in international organizations like the IPCC as part of their normal academic duties. They do not receive any extra compensation beyond possibly for direct expenses.
  • Scientific grants do not usually award any money to a scientist personally, only towards the cost of his or her scientific work.
  • There is not a shortage of useful things that scientists could study if they were not studying global warming.
    • Understanding our climate system better brings benefits independent of global warming. For instance, more accurate weather predictions save a lot of money (on the order of billions of dollars a year), and everyone from insurance agents to farmers wants climate data. Scientists could get paid to study climate even if global warming did not exist.
Q17: Doesn't the climate vary even without human activity? A17: It does, but the fact that natural variation occurs does not mean that human-induced change cannot also occur. Climate scientists have extensively studied natural causes of climate change (such as orbital changes, volcanism, and solar variation) and have ruled them out as an explanation for the current temperature increase. Human activity is the cause at the 95 to 99 percent confidence level (see the IPCC Fifth Assessment Report for details). The high level of certainty in this is important to keep in mind to spot mention of natural variation functioning as a distraction. Q18: Should we include the view that climate change will lead to planetary doom or catastrophe? A18: This page is about the science of climate change. It doesn't talk about planetary doom or catastrophe. For a technical explanation, see catastrophic climate change, and for paleoclimatic examples see PETM and great dying. Q19: Is an increase in global temperature of, say, 3 degrees Celsius (5.4 degrees Fahrenheit) important? A19: Though it may not sound like much, a global temperature rise of 3 degrees Celsius (5.4 degrees Fahrenheit) is huge in climate terms. For example, the sea level rise it would produce would flood coastal cities around the world, which include most large cities.
  • Earth's climate has varied significantly over geological ages. The question of an "optimal temperature" makes no sense without a clear optimality criterion. Over geological time spans, ecosystems adapt to climate variations. But global climate variations during the development of human civilization (i.e. the past 12,000 years) have been remarkably small. Human civilization is highly adapted to the current stable climate. Agricultural production depends on the proper combination of soil, climate, methods, and seeds. Most large cities are located on the coast, and any significant change in sea level would strongly affect them. Migration of humans and ecosystems is limited by political borders and existing land use. In short, the main problem is not the higher absolute temperature but the massive and unprecedentedly fast change in climate and the related effects on human societies. The IPCC AR6 WG2 report has a detailed discussion of the effects of rapid climate change.
Q20: Why are certain proposals to change the article discarded, deleted, or ignored? Who is/was Scibaby? A20: Scibaby is/was a long term abusive sock-master (or coordinated group of sock masters) who has created 1,027 confirmed sock puppets, another 167 suspected socks, and probably many untagged or unrecognized ones. This page lists some recent creations. His modus operandi has changed over time, but includes proposing reasonably worded additions on the talk page that only on close examination turn out to be irrelevant, misinterpreted, or give undue weight to certain aspects. Scibaby is banned, and Scibaby socks are blocked as soon as they are identified. Some editors silently revert his additions, per WP:DENY, while others still assume good faith even for likely socks and engage them. Q21: What about this really interesting recent peer-reviewed paper I read or read about, that says...? A21: There are hundreds of peer-reviewed papers published every month in respected scientific journals such as Geophysical Research Letters, the Journal of Climate, and others. We can't include all of them, but the article does include references to individual papers where there is consensus that they best represent the state of the relevant science. This is in accordance with the "due weight" principle (WP:WEIGHT) of the Neutral point of view policy and the "Misplaced Pages is not an indiscriminate collection of information" principle (WP:IINFO) of the What Misplaced Pages is not policy. Q22: Why does the article define "climate change" as a recent phenomenon? Hasn't the planet warmed and cooled before? A22: Yes, the planet has warmed and cooled before. However, the term "climate change" without further qualification is widely understood to refer to the recent episode and often explicitly connected with the greenhouse effect. Per WP:COMMONNAME, we use the term in this most common meaning. The article Climate variability and change deals with the more general concept. Q23: Did the CERN CLOUD experiment prove that climate change is caused not by human activity but by cosmic rays? A23: No. For cosmic rays to be causing global warming, all of the following would have to be true, whereas only the italicized one was tested in the 2011 experiment:
  • Solar magnetic field must be getting stronger
  • The number of cosmic rays reaching Earth must be dropping
  • Cosmic rays must successfully seed clouds, which requires:
  1. Cosmic rays must trigger aerosol (liquid droplet) formation,
  2. These newly-formed aerosols must grow sufficiently through condensation to form cloud-condensation nuclei (CCN),
  3. The CCN must lead to increased cloud formation, and
  4. Cloud cover on Earth must be declining.
Perhaps the study's lead author, Jasper Kirkby, put it best: "...it actually says nothing about a possible cosmic-ray effect on clouds and climate, but it's a very important first step." Q24: I read that something can't fix climate change. Is this true? A24: Yes, this is true for all plausible single things including: "electric cars", "planting trees", "low-carbon technology", "renewable energy", "Australia", "capitalism", "the doom & gloom approach", "a Ph.D. in thermodynamics". Note that it is problematic to use the word "fix" regarding climate change, as returning the climate to its pre-industrial state currently appears to be feasible only over a timeframe of thousands of years. Current efforts are instead aimed at mitigating (meaning limiting) climate change. Mitigation is strived for through the combination of many different things. See Climate change mitigation for details. References

Record low temperatures at global warming summit

Could we include this reference in the article:

http://theweek.com/article/index/210181/irony-alert-the-unusually-chilly-global-warming-summit

"As negotiators from nearly 200 countries met in Cancun to strategize ways to keep the planet from getting hotter, the temperature in the seaside Mexican city plunged to a 100-year record low of 54° F."

SuzBenson (talk) 04:41, 11 December 2010 (UTC)

And how would the temperature in a single city on a single day have any relevance to an article about long-term global temperature trends? --CurtisSwain (talk) 05:53, 11 December 2010 (UTC)

It was making a point. Few doubt that we went through a hot spell but many in Europe now believe we are entering a cold spell with poor summers for the last four years and increasingly bad winters with record cold temperatures in some countries like Britain. (Cyberia3 (talk) 00:55, 22 December 2010 (UTC))

Five isn't "many" compared to the population of Europe. Also see the FAQQ4. --Stephan Schulz (talk) 00:59, 22 December 2010 (UTC)

Still No Adequate Representation of Skeptical Perspectives In This Article

Every now and then I check back to this article to see if the "Editors" have allowed any skeptical information to creep into the article. Unfortunately, this article is still lacking any serious acknowledgment of the skeptical perspective.

The only times the skeptical perspective is even mentioned it is at the end of the article and couched in the fact that skeptical scientists are "funded" by the oil industry. Well, they aren't ALL funded by the oil industry. And sadly, there is no mention of the fact that many of the advocates' funding comes from government sources that would benefit from increasing regulation on energy production.

In the past, I have suggested that the folks who have editorial control over this page would be more intellectually honest if they would include a prominent skeptic who could negotiate a more balanced perspective. My suggestions were deleted by some ambitious editor. I suppose it was vandalism of some sort.

So, here I am again, pushing the idea of AT LEAST INCLUDING someone from the skeptical side of the aisle who could provide proper balance. I mean, are you people so threatened that you can't even listen to the other side?

Now, there is plenty of precedence on Misplaced Pages for including alternate perspectives in the presentation of controversial subjects (even when the alternate view has it's own article). Some examples:

  • If you look at the page for Creationism (http://en.wikipedia.org/Creationism), the article is fairly balanced between explaining the views that support and those that differ. The article explains the sources of various perspectives on the issue. There is also an article for Natural Selection (http://en.wikipedia.org/Natural_Selection) - so, there is precedence for including the contrarian view even if there is an article dedicated to the contrarian view.
  • The page for American Exceptionalism (http://en.wikipedia.org/American_exceptionalism) includes the counter-argument for American Exceptionalism in the second paragraph. So, that's very prominent.
  • The third paragraph of the article on Animal Testing (http://en.wikipedia.org/Animal_testing) includes the perspectives of both those who favor the practice as well as those who oppose it.

I propose that the Global Warming article would be stronger if skeptical perspectives were given proper treatment. Unfortunately, I expect that some "editor" will simple delete this suggestion as irrelevant. And of course, that would be dishonest. Mcoers (talk) 04:14, 20 December 2010 (UTC)

You don't have a reliable source or a specific piece of text to add, removed, or change. Therefore what you have isn't a "proposal" in the sense leading towards an edit to the article, but a "request." I'm sure someone will disagree with your request, but in my opinion ignoring it would be preferable giving your comment's lack of good faith. --CaC 174.52.224.148 (talk) 05:13, 20 December 2010 (UTC)
The problem in the case of this article is that the editorial process is controlled by people who delete all information that doesn't support their political cause. So, in this case, the proposal is to add qualified "skeptical" reviewers to the process so that people who do propose legitimately sourced information can have it reviewed in a process that is actually democratic. Rather than the current process which is terribly flawed.
In this case, I properly sourced the issue of providing alternative points of view within Misplaced Pages articles. So, no, it's not in bad faith. It's presented here in the context of the circumstances where information is systematically deleted if it doesn't support the cause of global warming. In this case, we can't improve the article until we improve the review process for making edits. Mcoers (talk) 05:20, 20 December 2010 (UTC)
Regardless of what you or I believe, I appreciate your act of good faith by proving a proposal. Before I move on to the discussion below, I just have one thing to say. Article talks are for the article, never the editors. What you are suggesting belongs at a notice board, I suggest either reliable sources noticeboard for the wider community to look at your sources, or more directly the administator's noticeboard if you believe there is editor abuse. --CaC 174.52.224.148 (talk) 05:48, 20 December 2010 (UTC)
I have already posted this information months ago to the administrator's noticeboard. I might as well have explained the problem to the rock beside my garage. Nothing has changed. It never does, despite the fact that hundreds of people have been on this discussion page proposing well-sourced information that has been summarily deleted. Misplaced Pages loses credibility when it does not include the ENTIRE story. Mcoers (talk) 06:00, 20 December 2010 (UTC)
This is what I have in reply:
  1. So you have posted to the Administrator's noticeboard? Perhaps not under a different name, because your edit contributions says otherwise.
  2. I looked at the proposal. A link to Archive 58 would have sufficed. In reading the previous discussion, this is my view:
    1. If this is about content: You don't have to YELL. What you are saying is clear, but others disagree with you, and you have not provided a satisfactory reply that would convince them otherwise.
    2. If this is about actual editor abuse: I'd like to see evidence, or you may present evidence at the administrator's notice board (which would be better).
Beyond that I have nothing to say. --CaC 174.52.224.148 (talk) 06:26, 20 December 2010 (UTC)
Ok, well, this is what I have to say to you CaC:
1. The only reason I re-posted the article proposal is because you said that you wanted to see a properly sourced article edit. So, I re-posted it. Obviously just leaving it in the archives doesn't do any good.
2. Yes, I did post a complaint about editor bias. If you can't find it, then perhaps it isn't there anymore. I have only one user credential for this site, and I don't pretend to be other people.
3. So, if people disagree with me, then that is grounds for eliminating my proposal from consideration? Well, that's great because I disagree with the way the entire GW article is written. So, by your logic the entire thing must be removed immediately. Hey, we may not agree, but the way these things are supposed to operate you need to give the opposing side a voice.
Obfuscating the lack of editorial diversity here by discounting dissenting opinion on the basis of any of dozens of technicalities does not make the case for Global Warming. Want proof of it? Well, I've just pointed out the fact that there is no mention of legitimate skepticism in the leading paragraphs of the article. If you need a link in order to make the point legit, then here it is: http://en.wikipedia.org/Global_warming. I have also sourced other articles that cover controversial subjects that do contain dissenting opinions. Those links are in the above thread. If you need me to repost them, I can; but then you'd get after me for re-posting information.
There is no mention of climategate at all.
The graphs that are included are created by some "dude" with an organization called, "Global Warming Art Project". What the heck is that?! So, if I have an art project called the "Skeptical Global Warming Art Project", then does that mean my stuff qualifies for publication here?
The timelines of these charts are cherry-picked to show a far more dramatic climb in temperature than what would be shown if the author used almost any other timeline. An improvement would be to show a chart of the last 10 years of global temperatures (which would show a decline). That way readers can see that, in fact, temperatures stopped going up around 1998. Mcoers (talk) 14:02, 20 December 2010 (UTC)
I think you believe your points are self-evident, which they are not. You don't need to repost an earlier post. List your main points, because right now I'm not quite sure which points you want me or someone else to reply to. --CaC 174.52.224.148 (talk) 15:57, 20 December 2010 (UTC)
Really? You mean to tell me that you actually don't understand what I'm saying? Here, let me say it again.
I want the editors who have authority to modify this page to allow skeptical information to be included in the presentation. There, do you understand that? Mcoers (talk) 16:29, 20 December 2010 (UTC)
I understand. Obviously your discussion lies with the "editors" and not me. --CaC 174.52.224.148 (talk) 19:49, 20 December 2010 (UTC)

Proposed Change to the First Paragraph of Global Warming Article

Back in January of this year, I proposed the following change to the Global Warming Article. At the time, it was swept under the carpet despite a significant level of support from other Misplaced Pages editors who are blocked from making edits to the Article. I would like to re-propose this edit in light of my previous suggestion that we allow Skeptical perspectives to be included in the article:

Begin Proposal

Global warming is a scientific theory that became popular in the 1980s to explain the observed increase in global temperature. The theory was proposed as a human-caused phenomenon, and is often referred to as Anthropomorphic Global Warming (AGW). Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century. However, the most recent decade has seen temperature declines in North America, Australia, and Europe. As a result, the controversy over human-caused global warming has increased. The Intergovernmental Panel on Climate Change (IPCC), The University of East Anglia, the National Academy of Sciences, and dozens of other education and governmental institutions have recently come under increased scrutiny as revelations of missing source data and allegations of fraud revealed in the "Climategate" scandal have called some of the fundamental assumptions made by leading AGW scientists into doubt. Sources to cite:

Leaked emails have surfaced showing leading proponents of AGW theory to have manipulated data and taken actions to destroy raw data in an effort to thwart Freedom of Information Act Mcoers (talk) 05:41, 20 December 2010 (UTC)

Well, Climategate can't be used like that because the scientists have been cleared of scientific misconduct multiple times by the reports that were commissioned into the matter. Also, I was under the impression that (depending on which temperature chart you favour) that this year is going to be either the equal hottest or equal second hottest on record globally, so unless I've got that wrong, there can hardly be any justification that the temperature is declining. Hitthat (talk) 07:51, 20 December 2010 (UTC)

Hitthat, if you look at the NOAA website that I cited (http://www.ncdc.noaa.gov/oa/climate/research/cag3/na.html), you can actually compare the various Month over Month (MoM) data trended for the last ten years (or any other period you choose). There has been an average decline of -0.66 degrees in North America between 2000 and 2010.
The averages fall out by month like this:
* January 2000 - 2010: -2.32
* February 2000 - 2010: -3.16
* March 2000 - 2010: +0.43
* April 2000 - 2010: -1.3
* May 2000 - 2010: -1.51
* June 2000 - 2010: +0.75
* July 2000 - 2010: -0.54
* August 2000 - 2010: -0.61
* September 2000 - 2010: +0.28
* October 2000 - 2010: -0.56
* November 2000 - 2010: +2.32
* December 2000 - 2010: -1.71
* Average temperature trend for the decade for North America: -0.660833333

Mcoers (talk) 13:59, 20 December 2010 (UTC)

Additionally, Climategate can and should be used "like that" because the emails that were disclosed clearly show these scientists colluding to avoid compliance with FOIA requests to see their source data. In fact, no one has seen their source data. The only way they can come to the conclusions they do (like your mention of this being the "hottest" year on record - which it isn't) is by modifying the source data - I think the word they use is to "cleanse it". Well, the whole point of peer-review is that the peer must have access to the same data and be able to reproduce the result.

Since they've obliterated the ability to do that, I think it is reasonable to include the fact that the information is unverifiable.Mcoers (talk) 14:25, 20 December 2010 (UTC)

I can see why you got nowhere with the administrator's noticeboard. The problems you identify are way beyond their powers to fix. You need to take these matters up with the UK House of Commons Science and Technology Committee, Lord Oxburgh of the Science Assessment Panel, and with Sir Muir Russell of the Independent Climate Change Email Review. Failing that, take your concerns straight to the United Nations, because they recently organised a Climate Change Conference in Cancún, Mexico, and seemed unaware of the points you are making. If you get anywhere with any of them, come back and let us know (e.g. the URL of the webpage where they retract their previous statements), and we will give the matter full and detailed coverage here. --Nigelj (talk) 18:17, 20 December 2010 (UTC)
Well, this is just sarcasm. Obviously you should try and keep your comments productive. Isn't that right? Mcoers (talk) 18:37, 20 December 2010 (UTC)
I don't think it's sarcasm. While temperatures have maybe decreased on some continents within the last few years, you cannot provide a source that concludes that this decrease casts scientifical doubts on the global warming research. If you yourself conclude that, that's original research. So if you're really convinced that you can disprove GW theory, you should indeed contact the panels mentioned by Nigelj. Wikiepdia is certainly the wrong venue to discuss your research results. The fact that investigations have been performed about those hacked emails is not related with the science discussed on the article page. Sorry. 85.178.140.24 (talk) 21:46, 20 December 2010 (UTC)
You are tilting at windmills. 97% of active publishing climatologists support the science behind AGW and many reliable sources do the same, as listed in the the article itself or in articles linked from the article. It is not fair and balanced to try to force the same weight to the arguments of opponents on this article when those opponents do not have nearly as much backing them up, and right now the evidence shows counterexamples. Misplaced Pages is not the place to try to forge a new path for science to take, as Misplaced Pages follows the scientists in the field themselves. If you have an issue with the science, then take it up with the scientists. If they consistently reject you, then perhaps you should take a hard look at your own perception of the body of evidence, rather than trying to force Misplaced Pages to give undue weight to your preferred sources and trying to put original research in a scientific article. --Cornince (talk) 03:17, 21 December 2010 (UTC)
Science isn't supposed to be the process of collecting together a bunch of like-minded partisans who go forth to promote their collective and negotiated mindset. It's supposed to be about the constant challenge of the scientific process.
I think that what I've provided here gives a justification for why skeptics have reason to believe that the AGW issue is overblown. This isn't a movement of oil industry hacks who are paid to have their opinions. I've listed off a decade of cooling in North America, backed by information provided by the NOAA; as well as information for the Southern Hemisphere and Europe. To my knowledge, these data don't exist to the public in other areas of Asia, Africa and so forth. So, it isn't something I'm able to cite as a source. Furthermore, I've given sourced information documenting the issues about corruption within the AGW research community.
  • The researchers weren't found guilty of wrongdoing? What does that prove? O.J. Simpson was acquitted for murder, but that doesn't mean he didn't do something wrong!
  • 97% of researchers believe something? I'd say 100% of Misplaced Pages editors believe in AGW - of course the "believers" squash out the "skeptics" here on Misplaced Pages in the same fashion they do in the literature, so the result is predictable. What percentage is required to disprove it? We all know the answer to that question.
At any rate, the controversy about AGW is a part of the story. It is blatantly ignored in this article. I think I'm making a very solid, sourced case, for changing the editorial process here, and not one of you is addressing that issue except with sarcastic, and I'll say flippant remarks which are not in the spirit of the type of discussion we're supposed to be having here.
I think it is entirely reasonable to respect the wishes of hundreds of contributing editors and help to make this article better by following the intent of the Misplaced Pages process and include a more diverse editorial review process, instead of pretending like the "other side" doesn't exist. Now, the question before you at this point is, are you on the side of freedom of thought and the thorough presentation of information, or are you just going to continue to push your political position and squash all dissenting perspectives in order to continue the appearance of consensus? Mcoers (talk) 16:38, 21 December 2010 (UTC)
I believe most of your concerns are addressed by the FAQ page. Mishlai (talk) 20:57, 21 December 2010 (UTC)
As stated above, Misplaced Pages is not a forum for the discussion of the topic. We believe the article has given appropriate weight to both sides, as can be shown here:
"The scientific consensus is that anthropogenic global warming is occurring. Nevertheless, political and public debate continues."
There is also a section of the article devoted to the controversy, giving appropriate weight to both sides.
As stated in WP:UNDUE, "Conspiracy theories, pseudoscience, speculative history, or even plausible but currently unaccepted theories should not be legitimized through comparison to accepted academic scholarship," and reiterated many times throughout WP:NPOV.
Misplaced Pages is not a forum and if you have an objection to Misplaced Pages policy, then this is not to place to give it. --Cornince (talk) 21:07, 21 December 2010 (UTC)
Well, you are ignoring the point of my proposal. Again: There needs to be skeptical representation among those who have the ability to make changes to this article. Failure to do that violates WP:NPOV. Furthermore, calling the fact of skepticism in a scientific theory pseudoscience is insulting to those legitimate scientists who do not agree with your assumptions (and yes, there are plenty of them). Perhaps you would like your work to be called a conspiracy theory?
Secondly, this page actually is, in fact, a forum for discussion for making changes to the article. That's what its for. If I attempt to make a change to the article without gaining consensus here first, then you would tell me to get consensus on the discussion page first. So, here I am doing it, and you say this isn't the forum for doing so. Can't have it both ways my friend.
Thirdly, the FAQ page is nothing but a bunch of excuses for tossing out legitimate criticism of the content of the page. The entire page is written from the perspective of someone who has zero intention of ever considering an opposing thought. Citing an FAQ that is created for the obvious purpose of suppressing dissent is not legitimate.
Finally, it is completely unreasonable to take the position that this one phrase at the end of the article is "giving appropriate weight to both sides". I'm sorry, but that is ridiculous. Again, please address the point of my criticism. And again, the point is a lack of diversity in the editorial process here. Mcoers (talk) 22:18, 21 December 2010 (UTC)
My apologies. I meant to say that what you were wanting put in the article, as though it were equal in weight to the scientific consensus, fit under "plausible but currently unaccepted theories." --Cornince (talk) 22:30, 21 December 2010 (UTC)
Which part(s) of the proposed paragraph are "plausible, but currently unaccepted theories"? What in that paragraph is factually inaccurate? Why, please be specific, should we not modify the current first paragraph to include this content? Mcoers (talk) 23:47, 21 December 2010 (UTC)
The paragraph itself does not describe global warming, gives undue weight to skeptical arguments and omits important information regarding the scientific consensus:
1) The phrase "became popular" gives the impression that global warming is merely the latest fashion, and diminishes the fact that global warming enjoys broad scientific consensus.
2) The phrasing mentions the global warming recorded, but then refers to recent cooling in selected regions. This omits the fact that 2000-2009 was the warmest period measured globally and to an uninformed reader would give the impression that global warming has stopped or reversed itself, when that is not the scientific consensus. The scientific consensus that global warming is continuing and will continue is omitted.
3) Regarding the increased scrutiny, the phrasing gives the impression that global warming is a theory in crisis and is coming under increased scientific doubt, when in fact it is not. In addition, it omits the fact that in the CRU emails, several independent investigations have found no fraudulent activity by the scientists. Also, the fact of the scientific consensus is ommitted in opposition to this point.
4) The paragraph gives no description of global warming or the major scientific findings regarding global warming, as represented in the scientific consensus and described in the article, but simply leads the article with the negative position.
This paragraph omits important information regarding the scientific consensus and gives the reader a warped view of the appropriate weight of arguments, in violation of WP:UNDUE as described above. Adding this paragraph as the first would therefore severely diminish the quality of this article. --Cornince (talk) 00:08, 22 December 2010 (UTC)
Amending point 1, "became popular" is a phrase unbefitting an encyclopedia on a matter of science. --Cornince (talk) 00:33, 22 December 2010 (UTC)
Regarding this statement:
"Thirdly, the FAQ page is nothing but a bunch of excuses for tossing out legitimate criticism of the content of the page. The entire page is written from the perspective of someone who has zero intention of ever considering an opposing thought. Citing an FAQ that is created for the obvious purpose of suppressing dissent is not legitimate."
We are supposed to assume good faith in other editors until it can be shown that they did not act in good faith. If you wish to express doubts, then please follow the process outlined here: Misplaced Pages:Assume good faith. (My apologies, this comment was written by me, but I had forgotten to log in. Edited signature so my IP address won't show.) --Cornince (talk) 01:11, 22 December 2010 (UTC)

Thank you, Cornice, for taking the time and effort to give an patient, informed, and reasoned answer. It is ironic that those who hold absolute beliefs contrary to fact accuse others of not listening. It is the global warming deniers who reflexively reject all data they don't like, and uncritically accept anything that seems to support their view. Rick Norwood (talk) 13:16, 22 December 2010 (UTC)

Yes. Well done, Cornice. --Nigelj (talk) 15:34, 22 December 2010 (UTC)
Agreed. Someone needed to do this. Thanks for taking the time to do it so well. Rollo (talk) 22:37, 24 December 2010 (UTC)
No, it isn't necessary. What is necessary is to figure out how to include skeptical information while retaining an accurate description of what the theory is about. Misplaced Pages shouldn't be a forum to "prove" global warming. It should describe what the theory is in the context in which it exists. This is the approach that is taken on other controversial subjects (as I pointed out in a previous post), and therefore it is the approach that should be taken for this one as well. Mcoers (talk) 19:48, 27 December 2010 (UTC)
Ok, Cornince. If I'm putting undue weight on something, then please explain how you would modify the first couple paragraphs to include an acknowledgment of the growing number of skeptical scientists who are publishing information that is contrary to the IPCC report? How do you include the fact that the few scientists who have access to the source data are hiding it from public review?
It is very important to make sure that this gets examined correctly. There are people who are proposing trillions of dollars in taxes that would have a hugely negative impact on the world economy and open the door to increased government/corporate corruption on a scale that perhaps has never been seen. Remember, Enron was built on this type of trading scheme - it is scary to think it could be so much larger.
The consequences of the "cure" for global warming could be far worse than the effects of the pollution. I see that you have a couple people on here clapping enthusiastically for your retort to my proposal, but you aren't addressing the issue that I'm presenting to the editors here:
Again, there is a lack of diversity among the editors of this article. Why can't there be a diverse group of editors? What are you afraid of?
The IPCC report, and much of the "consensus" information that is published in the literature all comes from the same few scientists who determine who gets to publish information in the literature and who have been caught suppressing the source data so that it cannot be independently reviewed. It is entirely appropriate for thinking people to have access to the underlying source data, as well as information on the methods used to normalize and cleanse it, so that the assumptions can be understood and the conclusions tested. The unsigned editor below in quoting the Investors.com article is trying to make that point. And it is an important one. The scientific method requires the theory to be falsifiable. We need to have a pluralistic discussion on the matter.
How on Earth can you be against such a Democratic process? Suppressing the fact that these scientists are colluding to avoid Freedom Of Information Act requests is a big deal. If it were any other subject, my guess is that you would be outraged.
I understand that we are supposed to assume good faith in the editors. So, I'm asking the folks here to *show* good faith and allow dissenting opinions to be expressed in this article. It will make the article stronger. If you disagree with how I worded the paragraph change, then show me how you would change it. Mcoers (talk) 19:48, 27 December 2010 (UTC)
"growing number of skeptical scientists" You are factually incorrect. 90% of actively researching climate scientists agree that temperatures have risen. Temperatures fluctuate, for example solar cycles are eleven years, ENSO three to five, and IPO fifteen to thirty. Therefore the standard for climate averaging is thirty years. The trends for every major model for the last thirty years are positive. To pick one of the hottest years due to ENSO and another in no now way shows a trend. To say temperatures are decreasing is plainly wrong. To give weight comparable to the scientific consensus is plainly undue. To conclude that temperatures are decreasing yourself is plainly original research. Undue weight (which is a part of NPOV) and no original research are Misplaced Pages's policies.

You've begun a thread on the conflict of interests noticeboard. If you're here to talk about people's motivation, keep it there. I have no reason to reply to what you have to say here.

Misplaced Pages is not a democracy. This is policy. The primary way in which editorial decisions are made on Misplaced Pages is through consensus (see WP:CON). Your text so far have failed either undue weight or original research. You do not have consensus. Unless you present references and text that satisfy undue weight and no original research, there doesn't need to be discussion. 67.190.48.91 (talk) 09:05, 28 December 2010 (UTC)

Can Global Warming Be Falsified?

Please see WP:NOTFORUM
The following discussion has been closed. Please do not modify it.


Since, no matter what happens with the weather, global warming is blamed, the theory cannot be falsified, hence must be classified as pseudo-science. Can anyone here name a single bonafide scientific theory that is immune to falsification? From investors.com: "Karl Popper, the late, great philosopher of science, noted that for something to be called scientific, it must be, as he put it, "falsifiable." That is, for something to be scientifically true, you must be able to test it to see if it's false. That's what scientific experimentation and observation do. That's the essence of the scientific method.

Unfortunately, the prophets of climate doom violate this idea. No matter what happens, it always confirms their basic premise that the world is getting hotter. The weather turns cold and wet? It's global warming, they say. Weather turns hot? Global warming. No change? Global warming. More hurricanes? Global warming. No hurricanes? You guessed it." http://www.investors.com/NewsAndAnalysis/Article/557597/201012221907/The-Abiding-Faith-Of-Warm-ongers.htm But since wikipedia is a leftist website, there is no chance that this non-falsifiable theory of Global Warming will receive adequate counter-argument in its propaganda article. —Preceding unsigned comment added by 67.183.191.86 (talk) 08:25, 27 December 2010 (UTC)

While I appreciate your interest in this topic, please note the banner at the top of the talk page.--CurtisSwain (talk) 08:59, 27 December 2010 (UTC)
This page is not a forum for general discussion about Climate change. Any such comments may be removed or refactored. Please limit discussion to improvement of this article. You may wish to ask factual questions about Climate change at the Reference desk.
Curtis, this is a talk page where we are supposed to discuss improvements to the article. This person is legitimately pointing out the political nature of the kinds of information that are included in the global warming article. It is popular among other editors to attempt to silence this kind of objection on any number of technicalities. However, the same level of scrutiny is not applied to those proposing the inclusion of information that is supportive of the AGW theory.
It is time to open this page up to a more democratic process of review. There is an increasing number of climate scientists who disagree with the "consensus" referred to in the IPCC report. The failure to acknowledge that fact is a glaring omission in this article.
Instead of looking for some technicality to disqualify someone's contribution, why don't you do something positive and help us figure out a way to reconcile the article to include information that is being presented by skeptical scientists. Mcoers (talk) 19:22, 27 December 2010 (UTC)

Science is not democratic. If fifty million people believe that the earth is flat, the wikipedia article should still state that the earth is round. Read the FAQs at the beginning of the article. The number of scientists who deny global warming is decreasing, not increasing. The evidence for global warming is increasing, not decreasing. The science behind global warming has been well understood for more than seventy years. The vast majority of people who provide talking points against global warming are politically or economically motivated and couldn't solve a freshman calculus problem to save their lives. Rick Norwood (talk) 12:50, 28 December 2010 (UTC)

Rick Norwood, please try to keep a cool head. Also, Science is not Misplaced Pages. If 50 million people believed the earth was flat, it should be included in the article of Earth. Not because it is "right" or "wrong", but because it is believed. The amount of information about it, though, is limited by the inforcment of the Undue Weight rule. WikIpedia articles should have a NPOV, as you should know. — Preceding unsigned comment added by Gunnar123abc (talk • contribs) 01:27, 30 December 2010 (UTC)

Here's how it is practiced in all the science articles: the view that the earth is round should be stated as though it were fact (of course, it would still be referenced), and then further down the article, in the history section, there should be mention of the minority/fringe belief by the 50 million that the earth is flat, but it should be stated as their opinion. --72.155.192.9 (talk) 04:34, 30 December 2010 (UTC)
Please ask your question over at WP:RD/S. ~AH1 21:14, 30 December 2010 (UTC)
There is no "should" about it, as popular opinion has nothing to do with science, is not required as ratification or commentary on science. Unless the article one has in mind is popular opinion about science, a common confusion. - J. Johnson (JJ) (talk) 22:41, 30 December 2010 (UTC)
Perhaps what we could include in the article, though, is the factors of falsifiability present for the anthropogenic global warming theory. ~AH1 00:26, 31 December 2010 (UTC)

I don't see how the (easy) question of falsifiability of global warming is any different from the question of how other scientific theories are falsifiable. All that would be necessary is to show that ten year average temperatures have not gone up but rather have gone down or stayed the same, or that CO2 levels have not risen, that the oceans are not rising and becoming more acidic, that the ice cap is not melting, that CO2 is actually transparent to infrared, or that burning fossil fuels does not produce CO2. Any one of these would "falsify" global warming. None are at all likely, but they could happen if the global warming deniers were correct. Rick Norwood (talk) 12:56, 31 December 2010 (UTC)

100% of climate predictions, where Global Warming was the theme, made prior to this date 1st of January 2011 has turned out to be 100% false.98.165.15.98 (talk) 17:29, 1 January 2011 (UTC)

Definition

In the first sentence, why is the term "Global Warming" defined using the phrase "since the mid-20th century"? That seems to be an arbitrary restriction on the definition with no reference given. Global warming has been happening for 12000 years (see e.g. http://en.wikipedia.org/Timeline_of_glaciation#Land-based_chronology_of_Quaternary_glacial_cycles). Has this definition been erroneously transferred from "anthropogenic global warming"? Or does Misplaced Pages make no distinction between cause and effect? Mrdavenport (talk) 19:44, 28 December 2010 (UTC)

As per the article hat-note (before the first sentence), what you're looking for may be in Climate change or Paleoclimatology. --Nigelj (talk) 20:07, 28 December 2010 (UTC)
