By Phil Renforthon, Eos/AGU. For GSS Climate Change chapter 10. Excerpt: The oceans contain more carbon than soils, plants, animals and the atmosphere combined. Every cubic meter of seawater contains about 120 grams of negatively charged bicarbonate ions, which are balanced with positive ions such as calcium and magnesium. This carbon pool was created naturally over millions of years by mineral weathering. A recent review article published in Reviews of Geophysics explores the possibility of accelerating weathering processes to increase bicarbonate ions in the ocean, and thus prevent climate change and potentially ameliorate ocean acidification. The editors asked one of the authors some questions about the scientific basis for this idea and how it might work in practice.... https://eos.org/editors-vox/preventing-climate-change-by-increasing-ocean-alkalinity
