A finding published in US journal Science has shown that the oceans are heating up faster than previously thought. The finding has debunked previous reports that suggested a pause in global warming. Ocean water has heated 40 percent faster than previously estimated by a United Nations panel five years ago. This is important because oceans have provided a critical buffer by absorbing 93 percent of heat trapped by greenhouse gasses. The thermal expansion of water as a result of warming of oceans could lead to 30 centimetres above sea level which is much higher than sea level rise from melting glaciers.

“2018 is going to be the warmest year on record for the Earth’s oceans,” said Zeke Hausfather, author of the study speaking to The New York Times.

The extra warmth of oceans can decrease oxygen in it and damage coral reefs. Warming seas are also the reason behind increasing frequency of powerful storms and it also leads to higher sea levels by melting ice.
