One thing I would have liked to see in the paper is a quantitative side - by - side comparison of sea - surface temperatures and upper ocean heat content; all the paper says is that only «a small amount of cooling is observed at the surface, although much less than the cooling at depth» though they do report that it is consistent with 2 - yr cooling SST trend — but again, no actual data analysis of the SST trend is reported.

Here we analyze a series of climate model experiments along with observational data to show that the recent warming trend in Atlantic sea surface temperature and the corresponding trans - basin displacements of the main atmospheric pressure centers were key drivers of the observed Walker circulation intensification, eastern Pacific cooling, North American rainfall trends and western Pacific sea - level rise.

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).

Sea surface temperatures in the Western Pacific are well above climatology, and it has been argued that the warmth in the Western Pacific along with the lack of an equivalent long - term warming trend in the Eastern Pacific, increase the chances of a «super El Niño,» comparable to the two strongest El Niños of the past century, which occurred in 1998 and 1983.

For example, let's say that evidence convinced me (in a way that I wasn't convinced previously) that all recent changes in land surface temperatures and sea surface temperatures and atmospheric temperatures and deep sea temperatures and sea ice extent and sea ice volume and sea ice density and moisture content in the air and cloud coverage and rainfall and measures of extreme weather were all directly tied to internal natural variability, and that I can now see that as the result of a statistical modeling of the trends as associated with natural phenomena.

Thirty years is far too short to encompass a cycle for the Arctic sea ice where the major cycle is at least 70 years — the best cycle context for this I have found is represented in the State of the Arctic Report or the work of Igor Polyarkov at IARC Fairbanks — looking at Surface Air Temperature trends for the whole Arctic — 60 - 90N, for the century you can see two peaks in 1940 and 2005 with a trough in the mid-80s (if anyone can tell me how to copy in a jpg I could put one in here!).

I'm inclined to think that Ocean Heat Content, trends in land ice and Sea levels are more appropriate indicators of global climate change than surface air temperatures, but that's another issue.

These trends in extreme weather events are accompanied by longer - term changes as well, including surface and ocean temperature increase over recent decades, snow and ice cover decrease and sea level rise.

This trend is closely linked to rises in the average temperatures of the sea surface.
