What can happen when the oceans become more acidic

Web9 feb. 2024 · Like global warming, this phenomenon, which is known as ocean acidification, is a direct consequence of increasing levels of carbon dioxide (CO 2) in Earth’s atmosphere.

Carbon dioxide (CO 2) is a greenhouse gas, that humans are releasing into the atmosphere at rates exceeding historical values. In 2011, CO 2 accounted for 84% of all greenhouse gas emissions, and between 1990 and 2011 emissions had increased by 10%. We know that the release of greenhouse gases are increasing air temperatures.
