So where's the warming? Both poles have more ice than usual.
If you want to claim its the oceans, then you are going to have to explain where your heat pump is, or why the oceans just now started warming instead of a hundred years ago. Yes I have had this conversation before.
We do have AGW, but it is caused by humanity shifting the water vapor equilibrium (through irrigation, paving, combustion, and cooling towers). It is a tight equilibrium, so there is very little chance of runaway global warming. Ocean acidification, however, is an extreme problem that is far more likely to do grievous harm to humanity. But no-one wants to actually think for themselves and do the calculations themselves. They just want to fit in.
