I'm not sure I totally understand this post, but if the ocean has cooled slightly as part of natural fluctuation «noise,» and if last year's hurricane season (with Katrina, et al.) happened during this natural cooling fluctuation, and if the ocean is on a general track of getting warmer, then we probably have much much worse to expect in future hurricanes....

Oleg Sorokhtin of the Russian Academy of Sciences Institute of Ocean Studies, and many other Russian scientists maintain that global climate depends predominantly on natural factors, such as solar activity, precession (wobbling) of the Earth's axis, changes in ocean currents, fluctuations in saltiness of ocean surface water, and some other factors, whereas industrial emissions do not play any significant role.

I would have thought that was a more reasonable view than a large coincidental natural fluctuation that somehow also more rapidly warmed the land, removed Arctic sea ice and raised ocean heat content while giving us the warmest decade on record.

On the other hand, some of the long - term change in the AMO could be driven by natural variability, e.g. fluctuations in thermohaline flow.

Some skeptics have attributed contemporary climate change to natural fluctuations in solar activity, rather than human - emitted greenhouse gases — the explanation endorsed by nearly all climate scientists, including those convened by the Intergovernmental Panel on Climate Change.

They have long appreciated - ever since the early 1990s, when the global warming bandwagon first started to roll behind the gravy train of the UN Intergovernmental Panel on Climate Change (IPCC)- that such short - term climate fluctuations are chiefly of natural origin.»

«We evaluate to what extent the temperature rise in the past 100 years was a trend or a natural fluctuation and analyze 2249 worldwide monthly temperature records from GISS (NASA) with the 100 - year period covering 1906 - 2005 and the two 50 - year periods from 1906 to 1955 and 1956 to 2005... The data document a strong urban heat island eff ect (UHI) and a warming with increasing station elevation... About a quarter of all the records for the 100 - year period show a fall in temperatures... that the observed temperature records are a combination of long - term correlated records with an additional trend, which is caused for instance by anthropogenic CO2, the UHI or other forcings... As a result, the probabilities that the observed temperature series are natural have values roughly between 40 % and 90 %, depending on the stations characteristics and the periods considered.»
