'Rock dissolving' method of geoengineering to mitigate climate change would not be easy

Monday, January 21, 2013 - 20:00 in Earth & Climate

The benefits and side effects of dissolving particles in our ocean’s surfaces to increase the marine uptake of carbon dioxide, and therefore reduce the excess amount of it in the atmosphere, have been analyzed in a new study.
