<i know this is 3 days later, I'm sorry> So when I said that the ocean has 1000x the mass of the atmosphere, I did the math earlier to get the total mass of both. That is a different calculation than the below per unit of volume measurement. Sea water has a mass of ~1000kg/m^3. Sea level air has a mass of 1.2kg/m^3. How does it only take 4 times as much energy to heat up a cubic meter of seawater than a cubic meter of air? Wouldn't it be ~820 times as much?
