In its latest report the IPCC has
said that the oceans have been warming rather than the sky, in an effort to explain
away the problem of the lack of atmospheric warming for 15+ years. This does solve the problem of what Trenberth
called the "missing heat" -- the lack of global warming for (now on)
15 years.
While the missing heat problem is
potentially solved by claims of ocean warming, the explanation introduces another problem. If
something gets warmer, in this case the ocean, it is less likely to absorb heat, not
more; therefore making it less likely that heat from a warm atmosphere would be
drawn into the ocean, to be hidden in its deep recesses.
The energy is supposed to come
from the atmosphere, specifically its greenhouse layer. If the ocean is getting
warmer, the heat should be going outward not inward from it; so, it should be heating
the atmosphere, not cooling it!
The IPCC ocean heat model is sensibly based on the idea that heat must move from hot to cold, e.g. that there should be
no spontaneous take-up of heat by the oceans.
