Scientists acknowledge key errors in study of how fast the oceans are warming

I kinda want to re-up my comment from when this story was originally released a week or two ago.

The mass of the world's oceans is 1.4 × 10^21 kg. The mass of the world's atmosphere is 5.1480 × 10^18 kg. So the oceans have a mass that is 272 times as large as the atmosphere. So if they're predicting a 2C rise in the atmosphere, and all that energy went into the ocean, the ocean would warm by 2/272 = 0.0073 degrees.

How is it even possible to measure something so small on something as massive and varied as the ocean?
