Final answer:
Climate change affects the ocean by causing ocean acidification, rising sea levels, and shifts in marine populations.
Step-by-step explanation:
Climate change affects the ocean in several ways:
- Ocean Acidification: As the ocean absorbs carbon dioxide emitted by burning fossil fuels, it becomes more acidic. This change in pH levels can threaten marine food webs, including coral reefs and salmon populations.
- Rising Sea Levels: Melting glaciers and the greater volume of warmer water contribute to an increase in ocean levels. This can lead to the inundation of shorelines, reduction in island size, and even disappearance of some islands.
- Changes in Marine Populations: Increases in greenhouse gas emissions, associated with global warming, can lead to shifts in marine populations due to changes in ocean temperatures.
