Oceans absorb more than 90% of excess heat created by greenhouse gas emissions and quantifying how much they have warmed up in recent years gives scientists an accurate read on the rate of global warming. That means the world's oceans have absorbed 228 Zetta Joules of energy in recent decades. "The amount of heat we have put in the world's oceans in the past 25 years equals 3.6 billion Hiroshima atom bomb explosions." The past five years are the five hottest years for the ocean, the study found. As well as the mid-term warming trend, the data showed that the ocean had absorbed 25 Zetta Joules of additional energy in 2019 compared with 2018's figure.
