Impacts of global warming on marine ecosystems: Ocean acidification and fish catches

The temperature of the earth has been increasing since the industrial revolution. In recent years, global warming has become more and more severe, so as to the warmer ocean. This paper focus on the response of the oceans to the global warming in physical, chemical, and biological. Under the current climate of global warming, the oceans play a huge mitigating role as thermal containers. And the oceans are also the largest carbon sink in the world. This leads to a serious pollution, ocean acidification, which may change the physical and chemical processes of the ocean and affect the environment of marine life. In the meantime, we point out that the nature internal variability also has great impact on the marine ecosystem, like fish catches. If we learn more the mechanisms of the internal variability, there would be less uncertainty of the ocean changes. Overall, we show a general picture of the effect of the ocean warming to our readers and try to give some constructive suggestions to the policy maker.
