Might be tangentially related to the alleged Alzheimer's disease drug Aduhelm, the anti-amyloid therapy, that did show some success in proxy variable (biomarker), but no success at all in curing the disease or its symptoms (no efficacy), but which got accepted with a huge amount of controversy by NDA (which disregarded its advisory committee’s recommendation against approving Aduhelm). --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 07:32, 30 July 2022 (UTC)
: More relevantly, it came out recently that [https://www.dailykos.com/stories/2022/7/22/2111914/-Two-decades-of-Alzheimer-s-research-may-be-based-on-deliberate-fraud-that-has-cost-millions-of-lives|the last ~decade and a half of Alzheimer's drug research] is based on monitoring effects in mice on a specific biomarker that ''may not actually exist in humans'', and the initial study was potentially fraudulent. Seems like a damn topical proxy variable to me. [[Special:Contributions/162.158.166.249|162.158.166.249]] 00:56, 31 July 2022 (UTC)
:"It’s not much of a stretch to suggest those amyloids are a primary cause of the associated memory loss and dementia," is the failed proxy hypothesis. [[Special:Contributions/172.69.33.163|172.69.33.163]] 02:47, 31 July 2022 (UTC)

I removed this paragraph:
:''Proxy variables are of interest to non-scientists as they provide a scientific way to indirectly monitor or improve the complex systems that affect their lives. For example, blood pressure is a causative factor for cardiovascular disease so it can be used as a proxy variable for healthy lifestyle.  However, people need to remember that it isn't necessarily the proxy variable alone that is of concern. Atmospheric carbon dioxide is not the only gas released by humanity with global warming potential and other factors affect climate change; and it is not carbon dioxide but the impact of climate change that will cause major social, economic, cultural damage to the future of the planet. ''
because I want to discuss it. The first sentence needs a source, the second and third sentences claim blood pressure is used by non-scientists as a proxy for living a healthy lifestyle, which I'm not sure about on multiple levels, and the fourth and fifth sentences seem like PR for fossil fuel companies. #notallgreenhousegases Nevertheless, I feel as if there are likely one or two good ideas hidden in it. [[Special:Contributions/172.70.206.95|172.70.206.95]] 16:01, 30 July 2022 (UTC)
:I feel like the author doesn't know the work climate scientists go to to avoid using greenhouse gas concentration as a proxy for global warming (all the models of atmospheric water and its forms.) For blood pressure, it's easier to see what was attempted to be gotten at. [[Special:Contributions/172.70.211.90|172.70.211.90]] 16:37, 30 July 2022 (UTC)
::Yes: the ones who dangerously simplify the climate change to "we must stop produce carbon dioxide" are not scientists but politicians. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 16:53, 30 July 2022 (UTC)
:Definitely. We don't even KNOW all factors affecting climate change. Still, the link between rising carbon dioxide and temperature looks much more solid that the link between money spent on fighting climate change and levels of carbon dioxide. ... Wait, you didn't wanted to talk about climate did you? :-) (For record, I always though there are much better reasons to stop using fossil fuels than fighting global warming. Recently, for example, the energetic security from geopolitically problematic regions came under lot of attention.) -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 16:46, 30 July 2022 (UTC)
::I want to talk about climate. Do you think we will be able to transition to carbon neutral and negative technologies in time to avoid the {{w|Jevons paradox}}? [[Special:Contributions/172.70.214.185|172.70.214.185]] 17:00, 30 July 2022 (UTC)
:::The Jevons Paradox exists if the only forces affecting the consumption of a resource are supply and demand. If you're asking about carbon-neutral/negative technological process making sustainable technologies profitable faster than fossil fuel profits grow, then no, there's no hope even before the Jevons Paradox is considered. But if other options are considered, the Jevons Paradox doesn't really apply. (To take an extreme example: It doesn't matter how fuel-efficient internal combustion engines get, they'll never be the preferred choice if their manufacture is banned.) [[User:GreatWyrmGold|GreatWyrmGold]] ([[User talk:GreatWyrmGold|talk]]) 18:14, 30 July 2022 (UTC)
::Only carbon negative technology requires {{w|Carbon-burning_process|5×10^8 K or 50 keV and densities > 3×10^9 kg/m3}}. I think that in the moment we will be using THAT on industrial scale we would be quite desperate. Also, the amount of energy we will need is going to grow unless we reduce population a LOT (like, for example, if all ecological activists would do the carbon responsible thing and commit suicide). Also, more and more of that energy we will need will be specifically electrical energy. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 20:21, 30 July 2022 (UTC)
:::We need to remove 38 gigatons per year, which is only 0.7 milligrams per square centimeter of ocean. Think of the mean depth of the ocean: that square centimeter is very tall. From that perspective, isn't this an easy biological solution? That's only 0.5 micrograms per minute, from the full depth of each square centimeter of ocean, right?

::::I'm not sure what is the "this" you talk about but it sounds you are only storing carbon, not removing it. BTW, one of best way to store carbon is to make more highways. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 23:07, 30 July 2022 (UTC)

:Everyone thinks this is about pharmacology, and maybe it is. But I've been taking economics courses this semester, so that's what I think of. "We can't measure this factor directly, so we made up a formula that should let us calculate it (if we've measured all relevant factors correctly and all our other assumptions and theories are valid)" is a pretty common thing in that field. [[User:GreatWyrmGold|GreatWyrmGold]] ([[User talk:GreatWyrmGold|talk]]) 18:14, 30 July 2022 (UTC)
: What's the best example, using GDP as a proxy for development? Or something current like using the money supply as a proxy for inflation? [[Special:Contributions/172.70.214.95|172.70.214.95]] 20:19, 30 July 2022 (UTC)

:This is the remainder from below, apparently objected to:
::''Proxy variables are of interest to non-scientists as they provide a way to indirectly monitor or improve the complex systems that affect their lives. For example, people use local temperature as a rough experiential proxy for the severity of global warming. Economists might mistake GDP for productive or useful development, or mistake the size of the {{w|money supply}} for {{w|price inflation}}. While correlated, the causation implied by such assumptions is very much in doubt, because the GDP increase of demolishing a hospital might conflict with the widespread understanding of development, and while the money supply size is a cause of inflation, there are many other causes.''
:But it's different from the original. Regardless of what my IP address may or may not suggest, I know the original objector to the earliest version does not object to this edited version, because that objector was and is me. However, I have not yet decided whether I think it should be in the explanation. I will let you know when it gets off the main page, like tomorrow, roughly in a day unless Monday morning continues its traditional trend of presenting unexpected immediate commitments. I have to run a long errand tomorrow so let's say Tuesdayish. 
:My initial impulse is to add another paragraph from the climate discussion above, and propose it for a subsection or collapse box.  [[Special:Contributions/172.70.214.81|172.70.214.81]] 14:35, 31 July 2022 (UTC) 
::How about inserting: "The rate and conditions of {{w|carbonic anhydrase}} expression in genetically modified {{w|phytoplankton}}, such as {{w|diatom}}s intended to sink to the seabed, could be one of many partial proxies for carbon negative direct ocean removal. However, {{w|geoengineering}} success is difficult to measure, and harder to predict, because sometimes even small biological changes in one organism, like modulation of a gene, can have wide-ranging ecosystem effects."
::Not sure where the paragraph break should be. If two paragraphs, try appending a subsection; if one, try the collapse box before the first title text paragraph. If people could contribute other interesting examples of proxies for carbon removal (I remember reading about a desalination process?) that would be awesome.

::: I have questions about the phytoplankton stuff. Is it true that completely carbon negative sequestration could be accomplished with 0.5 micrograms per minute (carbon or carbonate) for each square centimeter of ocean? How can the innoculator be sure the strain is viable but not destructive? Are there any {{w|synthetic biology}} proposals for new carbonate diatoms? Can you guarantee sufficient sinking buoyancy from carbonates alone, or is silicon necessary for sequestration? Won't ocean bottom-feeders or e.g. whales just eat the phytoplankton and return it to the ocean and atmosphere when they die? (There could be worse carbon removal solutions than those providing extra whale food, but I fear keeping it unpalatable to bottom-feeders would require making it hazardous for other ocean life. What was the desalination ocean carbon removal proposal?) [[Special:Contributions/172.70.211.90|172.70.211.90]] 15:47, 31 July 2022 (UTC)

:::: One reason that I don't think it should be the go-to counter-vandalism approach being used. But not for me to say. Whilstsoever I'm capable of intervening ''at least'' as much as any vandal tries to, I support the mod actions (they are there, doing things, BTW).
:::: Without actually tolerating the vandal, we easily outnumber the person concerned (and the very few other spammers/bots that sneak through the clearly effective existing speedbumps) and this means that such nuisance edits are heavily mitigated. If you see the damaged bits then you're either a regular or a very unlucky occasional visitor.
