I have to raise an objection to the phrase «the only region of the world that has defied global warming» — that might be neglecting a certain area in the Pacific where England 2014 has identified a very obvious point where the «Pacific conveyor» was bringing in the last decade up a lot of cold water from the deep ocean and has possibly played a major role in the specific trends for that period.

As Arctic sea ice species wane, southern taxa are re-colonizing waters their ancestors knew in past warm periods, and as parts of Bangladesh submerge Greenlanders find new opportunities.

If C02 is the largest single contributing factor to the Greenhouse Effect (because supposedly water vapor is only involved as a feedback to primary chemistry involving C02 itself), and C02 lags temperature increases (as has been stated on this very blog), how has the Earth ever returned to colder glacial conditions following periods of warming?

Re # 33 (Dave D.): Ice core measurement issues aside, remember that there has to be some degree of lag because a) the initial warming is from Milankovitch changes, not CO2, and 2) the delayed turnover of ocean water means that not all the CO2 will outgas in a short period of time.

«At the end of the last ice age around 11,000 years ago, the ice sheet went through a period of rapid, sustained ice loss when changes in global weather patterns and rising sea levels pushed warm water closer to the ice sheet — just as is happening today,» NASA said.

So, it is not surprising that those modellers who «need» to get warm surface waters to move into the depths of the oceans, and remain sequestered there for long periods of time, would turn to the physical mechanism of this vertical circulation system.

However, since this cycle takes hundreds of years, it could be that the current slow and small change in pH in the near surface waters since 1700 is due to the Medieval Warm Period rather than human co2 emissions.
