How an antacid for the ocean could cool the Earth

The article from MSN discusses a novel geoengineering approach aimed at mitigating climate change by using an "antacid" for the ocean. Scientists are exploring the idea of adding alkaline substances like lime or magnesium hydroxide to the ocean to counteract ocean acidification and enhance the ocean's ability to absorb carbon dioxide (CO2). This process, known as ocean alkalinity enhancement, could potentially remove CO2 from the atmosphere, thereby cooling the Earth. The concept involves increasing the ocean's pH, which has been decreasing due to the absorption of excess CO2, leading to acidification that harms marine life. By making the ocean more alkaline, not only would it help in reducing atmospheric CO2 levels, but it could also restore conditions more favorable for coral reefs and other marine organisms. However, the article also highlights the potential risks and uncertainties associated with this method, including unknown ecological impacts and the challenge of scaling up such operations to have a significant global effect.
