The former is likely to overestimate the true
global surface air
temperature trend (since the oceans do not warm as fast as the
land), while the latter may underestimate the true trend, since the air
temperature over the ocean is predicted to
rise at a slightly higher rate than the ocean
temperature.

Seems to me the debate about AGHG
global warming and increasing TC frequency / intensity / duration boils down to the fact that as sea
surface temperatures, as well as deeper water
temperatures rise, the wallop of any TC over warmer seas without mitigating circumstances like wind sheer and dry air off
land masses entrained in the cyclone will likely be much more devastating.
The
global surface temperature is already starting to
rise even without an El Nino, and ocean,
land and Arctic
temperatures have been
rising anyway with no pause.
Earth's
global average
surface temperature has
risen as shown in this plot of combined
land and ocean measurements from 1850 to 2012, derived from three independent analyses of the available data sets.
(It is frequently forgotten or overlooked in discussions of
global mean
temperature that
temperatures over
land rise much more than
temperatures over ocean — and ocean, of course, occupies roughly 70 % of the world's
surface.
