Final answer:
Ocean acidification is a primary concern among ocean scientists in relation to climate change impacts, caused by the absorption of atmospheric CO2 by the oceans.
Step-by-step explanation:
Among the concerns raised by ocean scientists regarding the outcomes of climate change, ocean acidification has been a prominent issue.
Ocean acidification occurs primarily due to the absorption of atmospheric CO2 by the ocean, which leads to chemical reactions that reduce the pH of the seawater. This phenomenon has significant implications for marine ecosystems, particularly for organisms with calcium carbonate structures, such as coral reefs, shellfish, and some species of plankton. As the oceans continue to absorb more CO2, their capacity to sustain diverse marine life deteriorates, potentially leading to a loss of biodiversity and disruption to many marine food webs.
Additionally, the other outcomes listed, such as sea level rise, more frequent hurricanes, and increased ocean salinity, are also concerns associated with climate change, but the question specifically asked about ocean scientists' views, and ocean acidification has been a central topic of research and discussion among marine scientists.
