A 2018 study by researchers from Oxford, the UK meteorological Office and the University of Texas at Austin calculated that over the course of the past 150 years, global warming has added the equivalent of one atomic bomb per second to the world’s oceans.
 

The website 4hiroshimas.info has produced the following widget that shows the oceans, land, atmosphere and melting ice, have contributed close to 5 billion Hiroshima bombs worth of heat since 1970. Ninety-three percent of which has gone into the ocean.

 

The widget also shows the number of Hurricane Sandy's, the number of point 6 earthquakes, Big Bens Full of Dynamite, and Million Lightning Bolts this amount of heat equates to.

 

The gif to the right is a visual representation of these bombs being detonated under water.

 

The world’s nine nuclear weapon states built about 70,300 nuclear warheads between 1940 and 2010 in accordance with the the military strategy and national security doctrine of mutually assured destruction. Whereby a full-scale use of nuclear weapons by two or more opposing sides would cause the complete annihilation of both the attacker and the defender.

After reaching a record high of 70,300 weapons in 1986, there has been a drawdown to approximately 3,750 active nuclear warheads and 13,890 total warheads. Which is 1/1,333,333th of the number of Hiroshima’s we have added to the ocean since 1970. All of which are going to come back to annihilate us, if we don't come up with an effective strategy for dealing with this heat. 

 

 On August 5, 1963, representatives of the United States, Soviet Union and Great Britain signed the Limited Nuclear Test Ban Treaty, which prohibited the testing of nuclear weapons in outer space, underwater or in the atmosphere.

 

Clearly we haven't lived up to the treaty with respect to the oceans and have to start doing so.
