Since 1983, the amount of carbon dioxide in the ocean is

Question

and the pH of ocean
water is

Answer 1

decreasing due to the process of ocean acidification. This is caused by the absorption of excess carbon dioxide from the atmosphere, which reacts with seawater to form carbonic acid. This process lowers the pH of ocean water, making it more acidic and less hospitable to many marine organisms. The effects of ocean acidification are expected to worsen as carbon emissions continue to rise.
