Abstract

Global warming has severely affected the biosphere, the problem of living conditions of living creatures seems to be extremely serious. However, people do not have a clear understanding of many species, including cetaceans. In fact, marine creatures and their ecosystem are extremely sensitive to climate change. This paper focuses on the changes caused by global warming to the ocean environment and the implications of these changes on cetaceans. The paper discusses rising sea-surface temperatures (SST) and ocean acidification resulting from global warming. These changes have had irreversible effects on cetaceans. SST is one of the most important parameters associated with the presence or absence of cetaceans and it is essential to discuss its impact on cetaceans on a case-by-case basis. As for ocean acidification, its impacts on cetaceans are mainly reflected by their food sources and habitats. These two changes always occur at the same time, and studies have demonstrated that rising SST can sometimes mitigate the adverse effects of acidification. Given the hidden impact resulted from global warming on the conservation status of cetaceans, the paper points out that additional research is required in many areas related to cetacean ecology that are currently poorly understood. In addition, more relevant predictions should be confirmed through detailed investigations and research, with a wider range of cetacean species being studied. The significance of this paper is evaluating effects of rising SST and ocean acidification on cetaceans and provide more available materials for cetaceans’ research.
