Study traces warming of oceans in last 150 years


The amount of heat that oceans have absorbed due to global warming is equivalent to one 1.5 Hiroshima-size atomic bomb explosion per second for the past 150 years, says new research.

According to a report on the Guardian, the research traces the amount of heat stored in the oceans since 1871 with computer models of ocean circulation.

The research was published in the journal Proceedings of the National Academy of Sciences.

Oceans absorb more than 90% of the heat trapped by global greenhouse gas emissions. This stored heat drives phenomena like sea level rise — which threatens the lives of billions of people living in coastal areas — and increased frequency and intensity of hurricanes and typhoons.

The research which reconstructed the amount of heat absorbed by the oceans in the study period found, for instance, that heat transfer by currents to the low and middle latitudes resulted in half the rise seen since 1971 at the region.
