Under: Human Influences Semi-protected edit request on 21 October 2014

Another human influence to global warming is the general public's misconception of the percentage of scientists that agree that humans are causing global warming. The reality is that 97% of scientists agree that humans are the cause, although the general public on average perceives a highly decreased percentage. There are real-world consequences to the consensus gap. If the general public would understand that climate scientists agree on human-caused global warming, they would be more likely to support policy to mitigate global warming. The consensus gap is directly linked to a lack of public support for climate action. This underscores the importance of clearly communicating the consensus and closing the consensus gap

Opposed as this article is about the generic idea of climate change, which includes, for example, the PETM millions of years ago. We already linked to the main article for the contemporary warming (the article "global warming", and we discuss that there in brief, and then link to various sub articles such as Politics of global warming and Public opinion on global warming and Climate change denial. Adding this social-science/public-policy influenced on the physical mechanics that influence the current climate change is..... too much. And it sorta disses the dinosaurs, who's era is also part of this article's generic subject. NewsAndEventsGuy (talk) 13:40, 21 October 2014 (UTC)
Not done: please establish a consensus for this alteration before using the {{edit semi-protected}} template. Semi protected edit requests are meant for non-controversial, simple edits.

Denier section

This was posted on my talk page after I left a note on another ed's talk page. I am moving here to document consensus for deletion of the section, at least at this article. NewsAndEventsGuy (talk) 07:54, 28 October 2014 (UTC) At first I didn't understand your first message, but I realized after I reverted it again what you meant. I've been looking at financial data for climate change denial and noticed that there wasn't much info on that page so I added to the denier section. But again, I now see why you preferred to keep current events out of that page, so it's okay to take my edit out if you insist! — Preceding unsigned comment added by Emilyscarr (talk • contribs) 07:06, 28 October 2014 (UTC)

Looking for a section or article on popular myths, misunderstandings or misinformation

Hi, I'd like to contribute to an article or section of an article on popular myths, misunderstandings or misinformation about climate change, I had assumed there would be a mention of it on this article, maybe I'm just looking for the wrong phrase? Thanks Mrjohncummings (talk) 10:05, 22 November 2014 (UTC)

Precisely what myths, misunderstandings or misinformation do you have in mind? HiLo48 (talk) 10:39, 22 November 2014 (UTC)
HiLo48 asks a good question... on other hand, if you just have the general topic in mind, see Global warming and from there the various sub-articles. Don't just read the current threads in talk pages - study the talk page archives. Links to the archives are usually in the yellow-orange section at top of each article talk page.

Climate Change Affects Everyone and Everything

Climate change affects everyone because temperatures are predicted to rise between two to six degrees Celsius (Cunningham, Mary Ann, and William P. Cunningham). As a result, climate change affects agriculture, wildlife, and the economy. To begin, warmer temperatures will affect agriculture by impacting crops and livestock. Climate change will reduce crop yields, and increase an animal's vulnerability to disease and reduce fertility (“Climate Impacts on Agriculture and Food Supply”). In addition, climate change will affect wildlife. By raising temperatures of habitats, animals that are intolerant to the heat will go extinct. Finally, the rising temperatures will affect the economy by increasing the amount of natural disasters. Having to repair the community after a natural disaster is financially draining. For instance, in 2011 alone, weather disasters cost the economy $53 billion in damage (“Extreme Weather: Impacts of Climate Change”). In conclusion, climate change affects everyone and everything. — Preceding unsigned comment added by 71.211.43.86 (talk) 21:25, 11 March 2015 (UTC)

Update spheres affected by climate change

The following section may require updating: "Internal forcing mechanisms

Scientists generally define the five components of earth's climate system to include atmosphere, hydrosphere, cryosphere, lithosphere (restricted to the surface soils, rocks, and sediments), and biosphere.[6]"

I would recommend updating this to read: "Internal forcing mechanisms

Scientists generally define the five components of earth's climate system to include atmosphere, hydrosphere, cryosphere, regolith (the soils, rocks, and sediments), and biosphere.[6] However, recent studies have shown that these components extend into the solid Earth to include the lithosphere and asthenosphere (magma). [1]"

The reason for replacing "lithosphere" with "regolith" is that until recently, the majority of the lithosphere was not recognised as being included in climate change responses. However, there are now multiple review papers and books describing movement of the magma in response to the mass shift associated with glacial and ice sheet melt, and with mass shifts due to changed movement of sediments. The review paper used as a reference cites most of these papers, but also brings together feedback mechanisms from multiple disciplines and includes discussion on all of the climate change affected spheres.

Clim8prim8 (talk) 21:31, 22 December 2014 (UTC)

If this "sticks" in the literature, then by all means... but that is yet to be known. IPCC's recent AR5 WG1 glossary has this entry, quoted in full

Climate system - The climate system is the highly complex system consisting of five major components: the atmosphere, the hydrosphere, the cryosphere, the lithosphere, and the biosphere, and the interactions between them. The climate system evolves in time under the influence of its own internal dynamics and because of external forcings such as volcanic eruptions, solar variations and anthropogenic forcings such as the changing composition of the atmosphere and land use change.

— IPCC AR5 WG1 Glossary - "climate system"
NewsAndEventsGuy (talk) 22:00, 22 December 2014 (UTC)

Thanks. The use of the word "lithosphere" although stated by the IPCC is not what they actually refer to. The lithosphere is far deeper than the processes assessed by the IPCC. The term "regiolith" refers to that component of the lithosphere that has been affected by erosion and the biosphere, and that is very shallow. As to the "stickiness" of this paper, the cited paper has only been available electronically since May 2014, but has already had over 44,000 downloads on ResearchGate in under 6 months, yet alone from other repositories. Clim8prim8 (talk) 23:21, 24 March 2015 (UTC)

"The use of the word "lithosphere" although stated by the IPCC is not what they actually refer to. " That may be, but we can't cite your own expert knowledge and the readership over 6 months isn't the determining factor for "stick" on this point. The real question is what do other scientists say when describing the climate system? Will they adopt anything for that paper, or stick with "lithosphere". For that matter, there's also research about how the thinning of the ice sheets is effecting earth's crust. For example, increased isostatic rebound involves more than the regolith, does it not? NewsAndEventsGuy (talk) 00:54, 25 March 2015 (UTC)

I take your point. Your last comment that increased isostatic rebound involves more than the regolith is a major component of the paper suggested here. Anthropogenic climate change is causing rapid changes to ice loss and therefore isostatic rebound. This is very well documented. Clim8prim8 (talk) 03:37, 30 March 2015 (UTC)

Arctic sea ice loss

Ocean currents and Jet streams

Arctic researchers reports and statements now suggest the following scenario: The Arctic Ocean will likely be essentially ice free for most of the month of Sept. That frigid Ocean will warm some due to sun exposure, so that next year one might expect two or three (best est 3) of ice free summer. Do the math (energy absorbed) and the Arctic Ocean will be ice free (year around) in maybe 5 years.

Weather patterns are primarily a function of ocean currents and the jet streams, the power of which in turn driven by the temperature difference between the poles and the more temperate latitudes. The rules of the game are changing. Farming will be severely impacted.

Not much to write, because none of it is in journal reviews. Here's the problem with climate models ... they missed balls of soot pollution on the ice surface absorbing solar radiation FAST [[1]].32cllou (talk) 17:50, 20 June 2015 (UTC)

When you find an RS on this topic, try Climate change in the Arctic or Arctic sea ice. If you don't have any RS, then see WP:FORUM and WP:SOAP. NewsAndEventsGuy (talk) 18:15, 20 June 2015 (UTC)
Statements and published reports from Arctic researchers affiliated with accredited universities, govt funded research data, and fairly straight forward math likely meets RS. You didn't read that article. Black soot from fires. Forest fires particularly, are significantly a function of climate change (natural or man influenced), and are a positive feedback factor for climate change. Climate change, such as a change in the difference between temperatures in the Arctic circle and lower latitudes. Additional facts should be here too, and thanks for the additional topic links.32cllou (talk) 19:36, 20 June 2015 (UTC)
The information/research on soot and other particulat pollutants 32cllou mentioned are wholly reliably sourced, I have to agree with NewsAndEventsGuy suggestion about that. Just a quick look at the reference provided seems to me it's legitimate and useful. Damotclese (talk) 00:03, 23 June 2015 (UTC)
But not in this article, unless they are supporting generic text rather than text about the current episode. NewsAndEventsGuy (talk) 01:42, 23 June 2015 (UTC)
Reading the article, I find much that requires, but lacks, source material. Much of what is properly here is dated! 2010 for ice loss, for example. The article (s, as you note) should go to the current level tracking, thus including the crash in 2012, rebound in 2013 and 2014, and now tracking to a worse (than 2012) crash in 2015.32cllou (talk) 19:49, 20 June 2015 (UTC)

This article, climate change, is for talking about the abstract concept, even when the dinosaurs were around. For the specific warming trend of today see global warming. NewsAndEventsGuy (talk) 20:02, 20 June 2015 (UTC)

Changes in mean vs. changes in spread

Would it help to have a focused section distinguishing between changes in mean (e.g., rising temperatures) vs. changes in spread (e.g., rising temperature standard deviation)? Is the physical evidence well separated that way? Thanks. Fgnievinski (talk) 20:51, 21 July 2015 (UTC)

During recent global warming, there have been few changes in large-scale temperature spreads. For most seasons / locations, the variance is consistent with unchanged. The only pretty clear exception is that high Northern latitude spreads in late fall / winter have declined, probably as a result of declining snow fall. Beyond that, I'm not sure what is really known about variance changes over longer time periods. Dragons flight (talk) 21:35, 21 July 2015 (UTC)

NASA scientists report that human-made carbon dioxide (CO2) continues to increase above levels not seen in hundreds of thousands of years: currently, about half of the carbon dioxide released from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and the oceans.[2][3][4][5]

Carbon dioxide in Earth's atmosphere if half of global-warming emissions[4][5] are not absorbed.

Climate Change page is misleading and does not accurately reflect the current use of the term "Climate Change"

The wiki page for "Climate Change" takes a rather literal meaning of these two words together and talks about changing climate through time. In English, the term "climate change" refers to the recent warming of the planet at an accelerated rate - the concept originating when scientists began predicting that the climate would continue to warm as humans emitted more carbon dioxide into the air. Early well presented positions were in the public view in the 1980's (though the subject matter has a longer history - see Wikipedia page on History of Climate Change). The concept of looking at how climate changes over long periods of time is called "paleoclimatology", and there is a separate wiki page for "paleoclimatology". The discussions about plate tectonics, orbital variations, and solar output do not belong on the wiki-page that people are directed to for a discussion of climate change unless these topics discuss how current scientific evaluations show that these factors can not explain the warming that has been observed over the last 30 years. I suggest that people who search Wikipedia for "Climate Change" should be directed to the current "Global Warming" page which addresses the current use of the term "climate change" and not to a incomplete discussion of paleoclimatology that appears to be designed to present other reasons the climate can change over geologic time (not the general use of the term "climate change" in English usage). 9Questions (talk) 02:21, 7 February 2016 (UTC) — Preceding unsigned comment added by 9Questions (talk • contribs) 19:34, 6 February 2016 (UTC)

The term "climate change" (originally "climatic change") has been in use for decades to refer to changes in climate on a variety of timescales. This google ngram result shows the evolution well. If you look into the "climate change" results for 2008 say, you find a subset that refers to changes to climate in the geological past, showing that the term is not only used as an equivalent to "global warming". With the hatnote and lead section and further information elsewhere in the article I don't personally see the problem with the current set-up - I don't think that anyone is being misled. Mikenorton (talk) 11:26, 7 February 2016 (UTC)
should be directed to the current "Global Warming" page - but people already are. The article begins "For current and future climatological effects of human influences, see global warming. For the study of past climate change, see paleoclimatology. For temperatures on the longest time scales, see geologic temperature record."William M. Connolley (talk) 18:29, 7 February 2016 (UTC)

Actually, this article is primarily about the general phenomenon (which is an observed and undisputed fact even among most so-called climate change sceptics/deniers), not about the anthropogenic climate change theory. I fail to see how this assumes or implies a political position. Also, of course, not every scientific theory that has political implications assumes a political position - in fact, it is usually the other way round. The theory that the Earth is spherical has the politically relevant implication that you can get to China by sailing west from Spain, but it does not assume that position. --Stephan Schulz (talk) 15:53, 3 March 2016 (UTC)
