The ocean temperature varies from place to place. Temperatures are higher near the equator and lower at the poles. As a result, changes in total ocean heat content best illustrate ocean warming. When compared to 1969–1993, heat uptake has increased between 1993 and 2017. [5]: 457
Another example of a species which may be seriously impacted by ocean acidification is Pteropods, which are shelled pelagic molluscs which play an important role in the food-web of various ecosystems. Since they harbour an aragonitic shell, they could be very sensitive to ocean acidification driven by the increase of anthropogenic CO 2 ...
Ocean acidification means that the average seawater pH value is dropping over time. [1]Ocean acidification is the ongoing decrease in the pH of the Earth's ocean.Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05. [2]
While the full implications of elevated CO 2 on marine ecosystems are still being documented, there is a substantial body of research showing that a combination of ocean acidification and elevated ocean temperature, driven mainly by CO 2 and other greenhouse gas emissions, have a compounded effect on marine life and the ocean environment. This ...
Global ocean temperatures have reached a record high, prompting warnings of serious consequences for the Earth’s climate. Reaching an average of 20.96C, according to the EU’s climate change ...
In addition, climate change impacts oceanic currents and sea levels, further altering fish distributions and habitats. Furthermore, ocean acidification, resulting from increased CO2 levels, compromises the ability of shellfish and corals to form shells and skeletons, further endangering marine ecosystems and the communities that depend on them.

A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid-century, according to a new study, and scientists have said before that such a collapse ...
The key issue in terms of the penetration of ocean acidification is the way the surface water mixes with deeper water or does not mix (a lack of mixing is called ocean stratification). This in turn depends on the water temperature and hence is different between the tropics and the polar regions (see ocean#Temperature). [100]
