Composite analysis of
global sea surface temperature during unusually wet and dry years also suggests a linkage between reconstructed rainfall and ENSO.
9) The correlation between CO2 content in atmosphere and sea surface temperature is connected especially with
global sea surface temperature during time periods when El Niño events are dominating.

global teleconnection associated with tropical
sea surface temperatures.
Global average
temperature is lower
during glacial periods for two primary reasons: 1) there was only about 190 ppm CO2 in the atmosphere, and other major greenhouse gases (CH4 and N2O) were also lower 2) the earth
surface was more reflective, due to the presence of lots of ice and snow on land, and lots more
sea ice than today (that is, the albedo was higher).

During that same period, average annual rainfall in New South Wales declined by 3.6 inches (92 millimeters).3 Scientists think the decline in autumn rainfall in southeast Australia since the late 1950s may be partly due to increases in heat - trapping gases in Earth's atmosphere.3, 14 Major bushfires over southeast Australia are linked to the positive phase of an ocean cycle called the «Indian Ocean Dipole» — when
sea surface temperatures are warmer than average in the western Indian Ocean, likely in response to
global warming.15, 16
3) In my comment https://judithcurry.com/2011/08/04/carbon-cycle-questions/#comment-198992 I have explained that
during recent three decades the increase of CO2 content in atmosphere is controlled by the rising
temperature of
global sea surface.
In other words, its shows that
global sea surface temperatures rose from 1910 to the early 1940s and from the mid-1970s to present because El Niño events dominated ENSO
during those periods, and it shows that
global sea surface temperatures dropped from the early 1940s to the mid 1970s because La Niña events dominated ENSO.
If this happens
during northern winter,
surface pressure falls in the Arctic (rising AO) the night jet stalls, NOx injection falls away, stratospheric ozone levels increase, the coupled circulation is invigorated and pressure falls at 50 - 60 ° north and this is associated with cloud loss (when
global cloud cover is at its maximum value) and a strong rise in
global sea surface temperature.

A study published Wednesday in Science Advances confirms once again that there was no
global warming hiatus or cooling period
during the past 20 years, an idea that had previously been raised in earlier assessments of
sea surface temperature data.
Using measured amounts of GHGs
during the past 800000 years of glacial — interglacial climate oscillations and
surface albedo inferred from
sea - level data, we show that a single empirical «fast - feedback» climate sensitivity can account well for the
global temperature change over that range of climate states.
Dr. Trenberth clearly stated that his calculations imply ~ 1 ″ of the rain that fell on New Orleans
during Katrina could be attributed to the change of
sea surface temperature associated with
global warming since 1970.
Here tests for causality using the
global mean near -

Global sea surface temperature (SST) has warmed by 0.4 — 0.8 °C
during the last century, although regional differences are evident [7,8].
During the Last Interglacial Period (about 129,000 to 116,000 years ago) when peak
global warmth was not more than 2 °C above pre-industrial
temperatures, and peak
global annual
sea surface temperatures were 0.7 [0.1 to 1.3] °C warmer (medium confidence), maximum GMSL was at least 5 m higher than at present (very high confidence), but did not exceed 10 m (high confidence).
Recent research highlights include new

during past episodes of
global warmth.
Weather satellites have been available to infer
sea surface temperature (SST) information since 1967, with the first
