In June 2015, NOAA researchers led by Thomas Karl published a paper in the journal Science comparing the new and previous NOAA
sea surface temperature datasets,
finding that the rate of
global warming since 2000 had been underestimated and there was no so - called «hiatus» in warming in the first fifteen years of the 21st century.
Hi Andrew, Paper you may have, but couldn't
find on «The phase relation between atmospheric carbon dioxide and
global temperature» CO2 lagging temp change, which really turns the entire AGW argument on its head: http://www.sciencedirect.com/science/article/pii/S0921818112001658 Highlights: ► Changes in
global atmospheric CO2 are lagging 11 — 12 months behind changes in
global sea surface temperature ► Changes in atmospheric CO2 are not tracking changes in human emissions.
Although the IPCC climate models have performed remarkably well in projecting average
global surface temperature warming thus far, Rahmstorf et al. (2012)
found that the IPCC underestimated
global average
sea level rise since 1993 by 60 %.
Back in 2009, by analysing the data, I
found that the
global average
sea surface temperature, the SST, stays fairly constant when the Sun is averaging around 40 sunspots per month.
Uncertainties of estimated trends in
global - and regional - average
sea -
surface temperature due to bias adjustments since the Second World War are
found to be larger than uncertainties arising from the choice of analysis technique, indicating that this is an important source of uncertainty in analyses of historical
sea -
surface temperatures.
By examining the spatial pattern of both types of climate variation, the scientists
found that the anthropogenic
global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing
sea surface temperature difference and thus intensify the circulation.
They
found that averaged
sea surface temperatures over the MDR are the best predictor of Atlantic cyclone activity, followed by
global average
surface temperature, with MDR warming relative to the tropics being the worst predictor of hurricane activity (Figure 1).
The integrated NAO (INAO) is
found to well correlate with the length of the day (since 1650) and the
global surface sea temperature record HadSST2 and HadSST3 (since 1850).
Emanuel, a recent convert to the theory of
global warming, had just concluded research that
found a link between rising
sea -
surface temperatures and the increasing destructiveness of hurricanes.
[1] Research
findings published in the science journal Nature in August suggest increased
sea surface temperatures as a consequence of
global warming, will lead to more intense hurricanes.

Recent studies have
found a large, sudden increase in observed tropical cyclone intensities, linked to warming
sea surface temperatures that may be associated with
global warming (1 - 3).
The team's
findings are controversial because they draw a connection between stronger hurricanes and rising
sea surface temperatures — a phenomenon that has itself already been linked to human - induced
global warming.
Specifically, the study
found that» [d] uring much of last year's hurricane season,
sea -
surface temperatures across the tropical Atlantic between 10 and 20 degrees north... were a record 1.7 degrees F above the 1901 - 1970 average,» «
global warming explained about 0.8 degrees F of this rise,» while» [a] ftereffects from the 2004 - 05 El Nino accounted for about 0.4 degrees F,» and a natural cycle in
sea -
surface temperatures «explained less than 0.2 degrees F of the rise.»
The atmosphere swap is
found to have much larger influence on sensitivities of
global surface temperature and Northern Hemisphere
sea ice cover.
The new
finding of the importance of multiple ocean
surface temperature changes to the multi-decadal
global warming accelerations and slowdowns is supported by a set of computer modeling experiments, in which observed
sea surface temperature changes are specified in individual ocean basins, separately.
