So the linked site claims 345 (+/- 2) zettajoules increase in energy for the top 2,000 m of oceans. Some calcs:
1. 1 zettajoule = 10 exp21 joules
2. Average depth of oceans = 3,682 m
3. Mass of oceans = 1.4 x 10exp21 kg
4. Mass of top 2,000m of oceans = 1.4 x 10exp21 x 2,000/3,682 = 5.4 x 10exp20 kg
5. Specific heat of water = 4,182 joules/kg
Claimed increase in temperature since 1955 = (345 x 10exp21)/(5.4 x 10exp20 x 4182) = 0.15 degrees C +/- 8.9 thousands of a degree.
How do you measure ocean temperature that accurately, especially back prior to the Argo ocean buoy deployment around 2000?
