Localised sea level rises?, page-49

Tinnitus I may be wrong, but I don't recall Plimer suggesting that at all, I think he was merely referring to the fact that it was more likely that any deep sea warming was more likely to be from sub-sea sources than from a small amount of atmospheric warming, which from a heat transfer point of view makes sense. I think he was also claiming that CO2 outgassing from the sea due to emissions from sub-sea volcanoes was not taken into account when claiming that volcanic sources of CO2 are low. I think the isotopic analysis of atmospheric CO2 puts that one to bed, but it is still a relevant point against the argument that some make that prior to the industrial revolution, atmospheric CO2 was somehow in a state of natural balance which we are upsetting. Such balance has never existed.

Sub-sea volcanism is the likely mechanism for the ice loss of the West Antarctic ice sheet by the way, It is very active due to the plate boundary extending down from South America. My wife has been swimming off the Antarctic coast in a bikini near some of the volcanic vents. One should not be surprised to see ice melting in warm water.
