Since I began commercial fishing in 1979 I have already seen many changes. Diminishing salmon runs, and other species are moving farther north, and warm water species like the Humbolt squid, tuna and ocean sunfish are becoming more common on the BC coast....Since the late 90s most fishing activity is taking place on the north coast, just south of the Alaska border
Warming and acidification of surface ocean waters will increase proportionately with cumulative CO2 emissions (see figure). Warm-water corals have already been affected, as have mid-latitude seagrass, high-latitude pteropods and krill, mid-latitude bivalves, and fin fishes. Even under the stringent emissions scenario (RCP2.6), warm-water corals and mid-latitude bivalves will be at high risk by 2100. Under our current rate of emissions, most marine organisms evaluated will have very high risk of impacts by 2100 and many by 2050. These results—derived from experiments, field observations, and modeling—are consistent with evidence from high-CO2 periods in the paleorecord.
Contrasting futures for ocean and society from different anthropogenic CO2 emissions scenarios
Global warming could wipe out vast numbers of marine species, a new report from a international group of researchers finds. Climate change, including rising temperatures, could force many species to relocate their native habitats, investigators conclude.
