According to the global analysis of over 300 sea creatures covering more than 100 years, the number of mammals, plankton, fish, plants and sea birds changes as our climate warms. While the number of species increases in the cold regions and places that were previously uninhabitable due to climate change become natural environment, the species in the hot regions tend to decrease due to the inability of the warmer climate. The research by the universities of Bristol and Exeter reviewed 540 records published about the number variation of the species. The team’s goal was to investigate how marine plants and animals react to the warming of the seas. For this, the records kept since the last century were also examined. The number of herring and penguins is decreasing in hot regions Martin Genner, a professor of evolutionary ecology at the University of Bristol, said they were reviewing data collected over the past century when the oceans’ temperature rose by 1 degree. Another researcher, Louise Rutterford, said that the number of sea creatures is limited between the cold polar regions and the hot equatorial regions, but they estimate the number of species to increase as the regions move towards the polar regions due to the warming seas with climate change. Rutterford stated that they think that the number of species in the equator regions will decrease because the warmer seas will begin to prevent life. Indeed, as a result of the researches, it was found that the number of herring and penguin species decreased in the hot parts of their flora, but increased in their colder parts. Rutterford noted that some sea creatures have gained an advantage due to these changes and others have problems, and this is especially true for species living in the equatorial areas. By 2050, the researchers, who noted that the temperature will increase by 1.5 degrees compared to the pre-industrialization period, predict that the number of species will change further in the coming years. Rutterford thinks that especially sea creatures will be affected by climate change. The researcher points out that this will enable more catching of hot water fish, but can also activate previously rare hot water parasites with the increase in temperature.
