Global warming of oceans equivalent to an atomic bomb per second - The Guardian

Seas absorb 90% of climate change’s energy as new research reveals vast heating over past 150 years

  Global warming has heated the oceans by the equivalent of one atomic bomb explosion per second for the past 150 years, according to analysis of new research.

  The total heat taken up by the oceans over the past 150 years was about 1,000 times the annual energy use of the entire global population.

  “Understanding ocean heat change and the role of circulation in shaping the patterns of warming remain key to predicting global and regional climate change and sea-level rise.”

  Dana Nuccitelli, an environmental scientist who was not involved in the new research, said: “The ocean heating rate has increased as global warming has accelerated, and the value is somewhere between roughly three to six Hiroshima bombs per second in recent decades, depending on which dataset and which timeframe is used.

  This new study estimates the ocean heating rate at about three Hiroshima bombs per second for the period of 1990 to 2015, which is on the low end of other estimates.”
