sea -
surface temperature anomalies over the northeast Pacific were driving storms (and moisture) away from California, but the
warming also caused increased humidity — two competing factors that may produce no net effect.
(1) The
warm sea surface temperatures are not just some short - term
anomaly but are part of a long - term observed
warming trend, in which ocean

Any way you look it, from the Climate Prediction Center Outlook through May, to the ongoing

Much of the recent
sea ice loss is attributed to
warmer sea surface temperatures with southerly wind
anomalies a contributing cause [Francis and Hunter, 2007; Sorteberg and Kvingedal, 2006], with thermodynamic coupling leading to associated increases in atmospheric moisture.»
These results suggest that
sea surface temperature pattern - induced low cloud
anomalies could have contributed to the period of reduced
warming between 1998 and 2013, and offer a physical explanation of why climate sensitivities estimated from recently observed trends are probably biased low 4.
«On May 22nd, 2014, global

warmest year (0.76 °C compared to the 1998
anomaly of 0.75 °C for the same months, and a 0.71 °C
anomaly for the whole year), while the land - ocean

sea surface temperature data) is trailing slightly behind (0.58 °C compared to 0.60 °C Jan - Sep, 0.56 °C for the whole of 1998).
Since 1850, CO2 levels rose, as did the «globally and annually averaged land and
sea surface temperature anomaly» (for what it's worth), but nobody knows whether or not the increase in CO2 had anything whatsoever to do with the
warming.
All we know for sure is that it hasn't
warmed (according to the «globally and annually averaged land and
sea surface temperature anomaly» record of HadCRUT) since the end of 1997.
The NINO3.4 index is defined as the average of
sea surface temperature (SST)
anomalies over the region 5 ° N - 5 ° S and 170 ° -120 ° W. El Niño (a
warm event) is considered to occur when the NINO3.4 index persistently exceeds +0.8 °C.
-- denying that the tropospheric land and
sea temperature anomaly (UAH) has
warmed more slowly than that at the
surface (HadCRUT3)(although it should
warm more rapidly according to the GH theory) and even stating exactly the opposite
However, during La Niña Modoki the
anomaly of the
sea surface temperature (SST) in the eastern Pacific isn't affected by cooling but by
warming just like western equatorial Pacific, while a cold
anomaly affects the central equatorial Pacific (Niño 3.4).
You are spending a lot of time rationalizing WHY there was a «standstill» in global
warming (as measured by the «globally and annually averaged land and
sea surface temperature anomaly»).
An El Nino analysis released by the national weather service last week says
sea surface and sub-
surface temperature anomalies were consistent with El Niño during December, but the overall atmospheric circulation continued to show only limited coupling with the
warm water.
The metric used by IPCC in all its reports for past and projected future «global
warming» has been the «globally and annually averaged land and
sea surface temperature anomaly» (as reported by HadCRUT3).
Regardless of whether or not the oceans integrate ENSO and portray it in
sea surface temperature anomalies, the West Pacific and East Indian Oceans
warm in response to both El Nino and La Nina events, so there is a cumulative response to ENSO by a major portion of the global oceans.
''... worked with two sediment cores they extracted from the seabed of the eastern Norwegian
Sea, developing a 1000 - year proxy
temperature record «based on measurements of δ18O in Neogloboquadrina pachyderma, a planktonic foraminifer that calcifies at relatively shallow depths within the Atlantic waters of the eastern Norwegian
Sea during late summer,» which they compared with the temporal histories of various proxies of concomitant solar activity... This work revealed, as the seven scientists describe it, that «the lowest isotope values (highest
temperatures) of the last millennium are seen ~ 1100 - 1300 A.D., during the Medieval Climate
Anomaly, and again after ~ 1950 A.D.» In between these two
warm intervals, of course, were the colder
temperatures of the Little Ice Age, when oscillatory thermal minima occurred at the times of the Dalton, Maunder, Sporer and Wolf solar minima, such that the δ18O proxy record of near -
surface water
temperature was found to be «robustly and near - synchronously correlated with various proxies of solar variability spanning the last millennium,» with decade - to century - scale
temperature variability of 1 to 2 °C magnitude.»
Sea surface temperature anomalies that persist over many years can be signals of regional or global climate change, such as global
warming.
The period of increased
warming from 1987 to 1997 loosely coincided with the divergence of the global average
temperature anomalies over land, which are derived from observation station recordings, and the global average
anomalies in
sea surface temperatures.
Over ocean stretches with a positive SST
anomaly air convection is higher (as the
temperature difference between the
warm sea surface and the cool air higher up in the troposphere is greater), so a higher likelihood for the formation of depressions exists and more precipitation is to be expected.
The best way to envision the relation between ENSO and precipitation over East Africa is to regard the Indian Ocean as a mirror of the Pacific Ocean
sea surface temperature anomalies [much like the Western Hemisphere
Warm Pool creates such a SST mirror with the Atlantic Ocean too]: during a La Niña episode, waters in the eastern Pacific are relatively cool as strong trade winds blow the tropically Sun -
warmed waters far towards the west.
However you slice it, lolwot, there is a current «pause» (or «standstill») in the
warming of the «globally and annually averaged land and
sea surface temperature anomaly» (used by IPCC to measure «global
warming»), despite unabated human GHG emissions and CO2 levels (Mauna Loa) reaching record levels.
If you are referring to the «globally and annually averaged land and
sea surface temperature anomaly», then this indicator has shown «cooling» since the end of 2000 (12 years) and lack of
warming since the end of 1997 (15 years).
Greenhouse gases continued to rise unabated, BUT instead of a
warming there was a net cooling of the globally averaged land and
sea surface temperature anomaly (HadCRUT3).
As a result of the leftover
warm water, the
sea surface temperature anomalies of the Rest - of - the - World appear to shift upwards in response to the strong El Niño events:
In fact, without the strong El Niño events, the Rest - of - the - World

(1) The

Here we quantitatively relate the impacts of
warm (and cold)
sea surface temperature anomalies in the eastern tropical Pacific Ocean to the number of hurricanes making landfall in the United States.
Further to my previous comments, it should be noted that the
warm anomalies («
anomaly» means the difference from the norm, whether yearly, seasonal, monthly, etc.) mentioned are
sea surface temperatures.
