claim: The oceans have absorbed much of this increased heat, with the top 700 meters ( about 2,300 feet ) of ocean showing warming of more than 0.4 degrees Fahrenheit since 1969.
evidence: Warming of the ocean accounts for about 93% of the increase in the Earth's energy inventory between 1971 and 2010 ( high confidence ), with warming of the upper ( 0 to 700 m ) ocean accounting for about 64% of the total.
