Warming waters due to global warming will result in rising of sea levels by about 30cm by the end of the century, in addition to the rise caused by melting ice and glaciers, says a new analysis.
Due to a process called thermal expansion, warm oceans take up more space. Warm ocean also leads to increased frequency and intensity of storms, hurricanes and extreme rainfall.
Even if the greenhouse gas emissions are halted, cooling down oceans — which play the most important roles in regulating the world’s climate — would require decades.
The report analysed four studies published between 2014 and 2017 and built a fuller picture of ocean warming than was previously possible.
