06.12.2024/Kiel. To mitigate climate change, carbon dioxide emissions must be reduced quickly and drastically. Additionally, some of the CO2 already emitted needs to be removed from the atmosphere. One solution is to enhance the ocean’s uptake of CO2 by increasing its alkalinity. The method mimics the natural process of rock weathering by adding ground rock, or its dissolution products, directly to the seawater. Little is known about the method’s effects on marine life. A new study has assessed the impacts of a moderate OAE application, showing that the effects on zooplankton are likely minimal and that the food web could remain stable. The results are published today in Science Advances.
