Impacts of climate change on marine biodiversity

The Ocean climate change is defined as the changes in the statistics of average seawater temperature, average ocean water salinity, average sea level rise, average sea height, average water pH range etc. was reported changed over the decades, years or even centuries. Due to human activities over land such as the burning of fossil fuels, deforestation, agricultural activities etc. causes an increase in the greenhouse gases in an atmosphere and which ultimately causes human-induced climate change. Due to the increased temperature primary productivity production, the process is affected, which impacted on the recruitment process of the other marine biodiversity, this phenomenon called a match-mismatch theory. The increasing melting of glacial causes an increase in sea level and sea height, this also impacted on ocean water salinity. The increased temperature impacted increased metabolic rates of phytoplankton and if that coupled with eutrophication then it will cause as algal blooms in the ocean. The changing environment also causes the cyclones, which destroys the coastal breeding and feeding grounds of marine biodiversity. The increased level of CO2 in the atmosphere causes more diffusion in ocean water, where it changes the pH of water, the process called ocean acidification. The ocean acidification impacts on marine biota such as corals, molluscs species etc. So it can be concluded that the potential adverse effects of climate change have posed a serious threat not only to marine biodiversity but also for humans. So in future, it is necessary to take proper steps towards minimizing the human-induced climate change activities were required, for this purpose, detailed research and awareness are becoming necessary.
