Two changes in the oceans that are driven by climate change are surface sea water temperatures and acidity. Several studies have documented the effects of these two changes on global fisheries. Sone of these studies were summarized by the famous fishery scientist Daniel Pauly in a recent comprehensive lecture in Los Baños, Laguna las December 2013. Dr. Pauly presented several graphs based on published papers authored by him and several other colleagues.
