Abstract: Global warming has become a global challenge having dire consequences on different aspects of the environment due to the melting of glaciers, excess carbon dioxide (CO2), and excess warming of water bodies among others. At a faster pace recently, climate change is affecting the marine environment, causing numerous alterations. Here, we address its consequences and the numerous alterations, which are more vital for researchers and global agencies to advocate more on why it’s essential to lessen the impact of climate change. Our review showed that the impacts of climate change are articulated at several stages of the marine ecosystem where it affects the inhabitants and their habitats. In response to climate change (ocean warming) marine species shift their latitudinal range to find suitable conditions leading to the redistribution of species. In addition, we found that growth reduction, sub-optimal behaviors, and reduced immune-competence of marine organisms, are as a result of thermal stress due to climate change. Also, the periodic changes in temperature above or below the optimum have a meditative reproductive effect on marine species, including fish. Finally, we discovered that due to higher water temperatures, several diseases showcase greater virulence in the sense that the marine species become less resistant to these diseases due to stress, increased virulence stimuli, or increased transmission.
