An international team of scientists determined the average temperature of our world’s oceans in 2021 was .075 degrees celsius higher than the 1981-2010 average.
Given the massive volume of oceans, an increase even this small would require a staggering influx of heat – 228 sextillion Joules worth. A hard number to contextualise, so scientists compared it to the amount of energy released by the atomic bomb dropped on Hiroshima, Japan.
Hiroshima atom bomb exploded with an energy of 63,000,000,000,000 Joules. The amount of heat we have put in our world’s oceans in the past 25 years equals to 3.6 billion Hiroshima atom-bomb explosions.
Averages to 4 Hiroshima bombs worth of energy entering oceans each second for 25 years. In 2020, ocean warming was equivalent to 5 Hiroshima bombs of heat every second, 365 days.
Ice is melting faster, causing sea levels to rise. Dolphins, marine life are dying. Heat makes hurricanes, typhoons more powerful, rainfall more intense. Each moment we delay taking action to slow down & reverse ocean warming, it’ll only get worse at an alarming rate of increase.
