Climate Change Indicators: Ocean Heat | US EPA
This indicator describes trends in the amount of heat stored in the world’s oceans.www.epa.gov
How much energy do you think that is? 18 e22 joules? That is equivalent to 43,020,000 MTons (43.02 terratons), 860,400 TIMES as powerful as the largest nuclear explosion ever set off (Tsar Bomba, 50 MT)
And that is not the ocean's total heat content. That is only the anomaly global warming has produced above the 1971-2000 average.
2) Climate history didn't begin in 1955.
Not better by any measure.
