Actually, there is some interesting work being done by Matt Huber of Purdue, following up on some earlier ideas of Emanuel's, suggesting that the role of TCs in transporting heat from equator towards the poles may be more significant
than previously thought — it also allows for some interesting, though admittedly somewhat exotic, mechanisms for explaining the «
cool tropics paradox» and «equable climate problem» of the early Paleogene and Cretaceous
periods, i.e. the problem of how to make the higher latitudes warm without warming the tropics much, something that appears to have happened during some past warm epochs in Earth's history.

Perhaps a change in instrument during the 1916 - 1984 time -
period occurred that would affect this urbanization effect; I can't imagine the same instrument has been operating since 1916 and I would suspect the instruments have been better designed to deal with heating up from solar exposure so they would probably record
cooler temperatures
than the older instruments.
Solar forcing has increased over the 20th century and given that the oceans have not yet had time to equilibrate to the new levels of forcing, it must have contributed some to the recent warming, in fact, that equlibration was further delayed by the
cooling period, so the unrealized climate commitment would have been greater
than ordinarily expected given that most of the increase in solar activity occurred in the first half of the century.

cooler than the 1961 — 1990 base
period, and this result emerges even without comparing the results to the instrumental record.»
