35% greater than the decrease projected for the global maximum catch potential ; . The global revenue potential loss for that period ranges from USD 6 to 15 billion , but impacts may be amplified at the regional scale for fisheries- dependent and low-income countries. The maximum revenue potential percentage decrease in the EEZ under RCP8.5 is estimated to be over 2.3 times larger than that of the high seas . Ocean acidification is also expected to drive large global economic impacts  , and there is high confidence that the integrated economic consequences of all interacting climate change-related factors would result in even larger losses. Changes in the frequency and intensity of extreme events will also alter marine ecosystems and productivity. Marine heatwaves can lead to severe and persistent impacts, from mass mortality of benthic communities to decline in fisheries catch . These events have very likely doubled in frequency between 1982 and 2016 and have also become more intense and longer ; for all future scenarios Earth System Models project even more frequent, intense and longer-lasting marine heatwaves .
