Climate change has drastically affected the ecosystem of marine life throughout the world. As the oceans are getting warmer, species that can cope up with raised local temperatures have increased nearer to the poles, while species living closer to the equator are shrinking in size. Martin Genner and his colleagues from the University of Bristol, UK  examined more than 300 marine species, including mammals, birds, fish and plankton, and their change in abundance within their usual habitat range. The researchers found that the warming of oceans by 1°C since pre-industrial times has triggered a widespread change in the marine ecosystem. Researchers have warned that ocean temperatures are projected to rise by another 1.5°C In the next 50 years, which indicates that this trend could continue.
