Science 305, 367-371 (2003). Ocean acidification and climate change, as expected by the middle of the 21st century, will pose a serious threat to marine biota, even under the most ambitious mitigation strategies (e.g. B of the SSP1-2.6 emission trajectory). In this study, we focused on the impact of three ambitious net CO scenarios {2} on the living conditions of tropical reef-building pteropods and corals. Pteropods play an important role in the marine food web43, especially in polar regions. Our study showed that much of the Arctic and Antarctic should become uninhabitable for pteropods, as high acidification results in seasonal under-saturation of large areas relative to the aragonite needed for pteropod plateaus. Previous studies have shown that changing aquatic chemistry and temperature already have a negative effect on pteropod survival and shell formation18,44. As our model shows, this trend is expected to continue over the next few decades, but particularly early CDRs can prevent large polar regions from being saturated with aragonite and therefore remain habitable for pteropods. In this study, we showed that, combined with the rapid reduction of CO emissions (“{2}”),” the early use of atmospheric DERE measurements could be effective in maintaining to a large extent the current oceanic physical and chemical conditions, provided that the Earth`s carbon cycle remains a carbon sink until the end of the 21st century. Given the subversal carbon cycle that would become a carbon source, as suggested by some model simulations34 provided by the Coupled Climate-Carbon Cycle Intercomparison Project (C-{4}) MIP, the early introduction of atmospheric cdR measurements would be much less effective (Figures 1 and 2, which were created with modified parameters for the terrestrial model, see additional table 1).

It shows that the future development of the Terrestrial biosphere is deeply linked to the marine biosphere and has the potential to accelerate the decline of biodiversity in the ocean. Early support of aggressive climate change trajectories with CDRs could help mitigate the most serious effects on key marine ecosystems. However, to achieve a significant effect, it is essential that CDR technologies be used as soon as possible, ideally over the next decade.
