Greenhouse gas emissions have caused the Indo-Pacific Warm Pool -the largest area of warm water in the world -to get hotter and increase in size, scientists have warned. The pool stretches about 14,484 km along the Equator and 2,414 km from north to south. It is an area of ocean with an average temperature of more than 28 degrees Celsius. Researchers, including those from Commonwealth Scientific and Industrial Research Organization in Australia and Ocean University of China, also found that if Indian Ocean section of the warm pool expands more than the Pacific part, it leads to an increase in rainfall in western Indian Ocean. But if this is reversed, it results in a decrease in rainfall over East Asia.
