A new study published Monday shows that the Earth’s oceans reached the highest temperatures and warmed the fastest since records began, highlighting the urgent need for global action to address the climate crisis before it’s too late. The study (pdf), “Record-Setting Ocean Warmth Continued in 2019,” which was published in Advances in Atmospheric Studies, found the oceans have warmed by around 0.075 degrees C above the average of 1981-2010. That level of warming, the paper found, is equal to 228,000,000,000,000,000,000,000 (228 Sextillion) Joules of heat. The amount of heat we have put in the world’s oceans in the past 25 years equals to 3.6 billion Hiroshima atom-bomb explosions. We are now at five to six Hiroshima bombs of heat each second.
