I noticed that the Ocean Acidification section of this page was very short, and I would like to add some detail on it. I would like to add details on the immediate effects of ocean acidification as well as the long term effects. These effects include what happens to smaller ocean organisms and larger ocean dwellers, and the resulting chain of events that could affect whole food chains and ecosystems as well as threaten the functioning of human society.Subsection: Ocean AcidificationEffects of ocean acidification would first hit creatures such as small crustaceans. The increased amount of hydrogen ions takes away from the production of calcium carbonate. This is important because calcium carbonate is a compound that’s necessary for zooplankton to construct shells, so not only are they zooplankton running out shell building elements, but the increased acidity can dissolve their shells as well putting entire food chains at risk as many fish depend on these zooplankton as a food source. The effects of Ocean Acidification can also be seen on coral, and other animals that require calcium carbonates to build their skeletons or shells. An effect called coral bleaching is the result of increased CO2 in the oceans, and this can be seen on the Great Barrier Reef in Australia, where ocean acidification’s effects are already taking place. The acidity can dissolve an organism’s shell or make it difficult for an organism to construct and keep a shell in order to grow and thrive, threatening whole ecosystems and food chains. --BriMcC16 (talk) 16:42, 19 April 2016 (UTC)[reply]

Brittany3000 (talk) 01:05, 4 October 2019 (UTC)How can the article be improved? Maybe add more information in the Oxygen Depletion section so it feels more complete.[reply]
I have been reading a lot of articles about the effects ocean acidification has on our oceans. This article does a great job of describing what ocean acidification is and the effects it has on calcifying organisms and how that can then effect the environment as a whole. I have been looking into articles that talk about how ocean acidification can have effects on the olfactory systems of marine fish as well, which then has negative consequences. I added on internal effects of ocean acidification on marine life after what has already been said about the effects it has externally on marine life. I have read articles about studies that have tried to understand how this could have negative effects. In the experiment that focuses on smaller marine fish larvae (orange clownfish), the scientists that conducted the experiment reared clownfish in three opposing pH levels: control (pH 8.15), a predicted pH for the next century (pH 7.8), and a pH predicted for even further into 2100 (pH 7.6). The results showed drastic differences from the pH of 8.15 and the pH of 7.8. The results for the pH of 7.6 were not recorded because the larvae reared in this pH had no reaction to any cues that were presented. I added a section describing this process and the experiment under the ‘Ocean Acidification’ section right before the paragraph that begins to talk about the steps that can be taken to combat these negative effects. I think this is a nice transition into the next section that talks solely about marine life.Kate Caputo (talk) 21:51, 28 November 2018 (UTC)[reply]
Global warming not only affected the the planets when it comes for forest fires or overall global heat, but it also affects the temperature of the oceans water. As the temperature of our planet increase, the ocean temperature does as well, becomes this a big issue due to the change in it's balance. The rising of the oceans temperature will endanger the marine life and the ecosystem that allows them to reproduce and live. [1]
I think an article such as this, which pulls together other topics under a common theme (effects of climate change), should use the excerpt function more. For example, the content under "ocean acidification" should probably be merged to ocean acidification and then replaced with an excerpt. Similarly for sea level rise for which there is a dedicated article, so we don't need to repeat the same content here in other words. This means the content would later only have to be updated in one place and not in two. If anyone is not yet familiar with the concept of excerpts, see here for example where I have used it a few times: Ocean#Threats. EMsmile (talk) 08:20, 2 July 2021 (UTC)[reply]
I propose to merge Effects of climate change on marine mammals into this article. I see lots of overlap of overlap and outdated information, which will be easier to update in just one article instead of two. See also discussion on talk page of effects of climate change.

Femkemilene I have closed the other 2 discussions as I got confused. So if you are still opposed I could close this as "no consensus". Or has EMsmile convinced you now? Chidgk1 (talk) 14:51, 8 February 2022 (UTC)[reply]
I've now copied some arguments for and against from the other talk page:
What would be the advantage of keeping it separately from effects of climate change on oceans? EMsmile (talk) 12:39, 28 October 2021 (UTC)[reply]
I feel that most of this article's content should also be merged to effects of climate change, so that the article reverts to becoming a quick overview article, mainly consisting of excerpts from other articles. Specifically, I am wondering where the bulk of the content about ocean currents (and their possible changes) should reside. I think it should be in effects of climate change, and then just an excerpt be used from there. I am even inclined to say that this article should perhaps be entirely merged into effects of climate change. Having all those "effects of climate change on XX" articles just creates too much work in maintenance, especially when they deal with physical phenomena which are all interlinked, not societal ones. EMsmile (talk) 09:41, 9 February 2022 (UTC)[reply]
The article effects of climate change on the water cycle has content about changes in salinity and also about ocean currents. My proposal is to bring ocean related content into this article and to refocus the other one on effects of climate change on water resources. I've also commented on the other article's talk page. In its current state, it overlaps too much with effects of climate change and Effects of climate change on oceans. EMsmile (talk) 14:03, 1 April 2022 (UTC)[reply]
I am working with content expert Tim Jickells on this article (he also helped a lot last year with ocean and also this year with eutrophication, harmful algal bloom and with Coastal waters). I've asked him for his opinion about this article and what he would change. Below you can find his suggestions:
Please add some info on/from this study to the article. It's currently featured in 2022 in science like so:
A study shows that climate change-related exceptional marine heatwaves in the Mediterranean Sea during 2015–2019 resulted in widespread mass sealife die-offs in five consecutive years.[1][2]
I already added info to it to the other two wikilinked articles. It's relevant here too and I think it should be added somewhere to section "#Biological effects and impacts on marine life", albeit the current section structure doesn't have summary section across many types of organisms so maybe you need to split the info to multiple sections or add a new section or add a summary to the top that also includes other info (not just this study).
Sadly figure 3 map in the study is not licensed CC BY and can't be uploaded/added here.

Hi User:Mikeblas, thanks for your help with this article. I see you've made some edits to the reference list, adding an additional list of sources. I plan to change this back so that the reference list is purely with the long ref style, not a mixture of long and short ref style. I've also talked about it more here in the past. And I hadn't noticed any cite errors for this article recently? Were they here or at ocean heat content? EMsmile (talk) 17:56, 19 October 2022 (UTC)[reply]
I've just copied some paragraphs from effects of climate change to the lead as I thought they were pretty good. However, they now introduce a bit of repetition in the lead. This is work in progress. In general, we need to ensure that this article integrates well with Effects of climate change and also with effects of climate change on the water cycle. EMsmile (talk) 09:28, 30 September 2022 (UTC)[reply]
There are many significant effects of climate change on oceans including: an increase in sea surface temperature as well as ocean temperatures at greater depths, more marine heatwaves, a reduction in pH value, a rise in sea level from ocean warming and ice sheet melting, sea ice decline in the Arctic, increased upper ocean stratification, reductions in oxygen levels, increased contrasts in salinity (salty areas becoming saltier and fresher areas becoming less salty),[1] changes to ocean currents including a weakening of the Atlantic meridional overturning circulation, stronger tropical cyclones and monsoons, and changing wind patterns.[2]EMsmile (talk) 20:40, 24 October 2022 (UTC)[reply]
Hi everyone, my group is working on this article for a class and we were thinking of adding on a sea turtle subs-section above the effects on marine mammals sub-section. Sea turtles are greatly affected by climate change in oceans, specifically due to temperature change and we think that this would be noteworthy in this wikipedia article. If you have any suggestions for us let us know! Mountsainthelena (talk) 21:58, 16 November 2022 (UTC)[reply]
Hello, I am currently editing this article to improve its readability. My work is part of a project focusing on improving the readability of climate change articles on Wikipedia.

I think the image that is in the lead is not very clear. It has a lot of arrows and text but doesn't make it very clear what the effects are, as distinct from the causes. I think a 2 x 2 image collage could work better, similar to the one at effects of climate change. The image collage could include:

Hello, I am working on this article for a class as you can see above. The main part of my project is updating the North Atlantic right whale#Climate change section, but my professor recommended that I simultaneously add a small section to this article under the impacts on marine life//marine mammals. I will likely employ an excerpt as used in other sections of this article. EcoBear13 (talk) 19:56, 17 November 2023 (UTC)[reply]

1. "The upper ocean (above 700 m) is warming the fastest, but the warming trend is widespread. " Can anybody help elaborate the expression of "but the warming trend is widespread", or use other wordings to make them easy to understand? 2. "The warming rate varies with depth: at a depth of a thousand metres the warming occurs at a rate of nearly 0.4 °C per century (data from 1981 to 2019), whereas warming occurs at only half that depth." the part "whereas warming occurs at only half that depth" seems to me incomplete, can anybody help? Thanks for your kind attention. ThomasYehYeh (talk) 13:26, 6 February 2024 (UTC)[reply]
