The overall heat increase is the same, but the localized effects mights not be: fewer beings live in the atmosphere, and air displaces that heat faster than water, reducing the local concentration.

That's not the case if you're comparing with AC. You have to use energy (generating more waste heat) to pump heat up a temperature gradient.

Wait, is that true? Fewer organisms in air versus water? Is that due to the huge amount of e.g. zooplankton maybe? Curious...
