Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

If we looked at only the ONI to determine changes in El Nino / La Nina frequency it would be misleading because that indicator is based upon a baseline that shifts; that baseline is determined from the very sea surface temperatures that would change if El Nino / La Nina become more dominant.

As a result, directly comparing the Sea Surface Temperature data from the early 20th century to the current Sea Surface Temperature data is like «comparing apples and oranges» — there have been too many changes in the data sources for such comparisons to have much meaning.

The other source of bias comes from a change in the way sea surface temperatures (SSTs) are measured.

«Much of our confidence stems from the fact that our model does well at predicting slow changes in ocean heat transport and sea surface temperature in the sub-polar North Atlantic, and these appear to impact the rate of sea ice loss.

There are secular changes in cloud associated with variable sea surface temperature — that vary from weeks to millennia creating warmer or cooler surface conditions.

See, the first thing to do is do determine what the temperature trend during the recent thermometer period (1850 — 2011) actually is, and what patterns or trends represent «data» in those trends (what the earth's temperature / climate really was during this period), and what represents random «noise» (day - to - day, year - to - random changes in the «weather» that do NOT represent «climate change»), and what represents experimental error in the plots (UHI increases in the temperatures, thermometer loss and loss of USSR data, «metadata» «M» (minus) records getting skipped that inflate winter temperatures, differences in sea records from different measuring techniques, sea records vice land records, extrapolated land records over hundreds of km, surface temperature errors from lousy stations and lousy maintenance of surface records and stations, false and malicious time - of - observation bias changes in the information.)

However, a confident assessment of human influence on hurricanes will require further studies using models and observations, with emphasis on distinguishing natural from human - induced changes in hurricane activity through their influence on factors such as historical sea surface temperatures, wind shear, and atmospheric vertical stability.

This accounts for a change in bias that arose from changing the source of sea - surface temperature analysis.»

Doing this on a year - to - year basis shows NO apparent correlation with the absolute «globally and annually averaged land and sea surface temperature anomaly» (i.e. HadCRUT3), but does show a weak correlation with the CHANGE in temperature from the previous year, for example:

There is a recognised bias in the dataset from the period around WWII associated with changes in the nationality of the shipping fleets taking sea surface temperature measurements - the main contributor to the temperature record - due to the war.

In so far as the air circulation fails for a time to maintain temperature stability then radiation from surface to space will also change but in due course stabilty is always restored between the four said parameters (sea surface / surface air / sun to sea / air to spaceIn so far as the air circulation fails for a time to maintain temperature stability then radiation from surface to space will also change but in due course stabilty is always restored between the four said parameters (sea surface / surface air / sun to sea / air to spacein due course stabilty is always restored between the four said parameters (sea surface / surface air / sun to sea / air to space).

These frequency changes are consistent with other paleoclimate indicators from the tropical North Atlantic, in particular, sea surface temperature variations.

Not only that, but there is increasingly compelling evidence that the recent short - term slowdown in the surface temperature record was much less pronounced than previously estimated, if rapid Arctic warming is fully reflected, along with potential biases from the changing mix of sea surface temperature measurement sources in recent years.

Ho added that the enhanced intensification of tropical cyclones over East Asian coastal seas caused by changes in sea surface temperature and wind flows mean that «an individual tropical cyclone could strike East Asia, including the Philippines, with a record - breaking power, for example Haiyan, even though landfall intensity in south - east Asia has not notably changed on average in recent years because of the shifted genesis location; note that Haiyan formed over the eastern Philippine Sea far from land.&raqsea surface temperature and wind flows mean that «an individual tropical cyclone could strike East Asia, including the Philippines, with a record - breaking power, for example Haiyan, even though landfall intensity in south - east Asia has not notably changed on average in recent years because of the shifted genesis location; note that Haiyan formed over the eastern Philippine Sea far from land.&raqSea far from land.»
