The near -
surface ocean temperature before the storm's passage was upward of 30 degrees Celsius (86 degrees Fahrenheit), and after passage the temperature was still around 28.5 C (83 F).
Not exact matches
Sea
surface temperatures in the tropical Atlantic and tropical Pacific
oceans three to six months
before the peak of fire season are strongly correlated with total fire activity.
They also looked at recent
ocean conditions, in particular the
temperature of the sea
surface near Japan and Florida the winter
before a given breeding season.
Their research approach has been used extensively
before, but applied mainly to
surface and
ocean temperatures.
Basically per the work of Zeebe and others, the idea is that in those times (and today) the rates of CO2 emissions, and
temperature increases, overwhelmed the short term feedbacks (biosphere,
surface ocean etc),
before the long term feedbacks (deep
ocean, weathering, etc) could cut in to process them.
Another problem, as has been mentioned
before, is that about 98 % of anthropogenic CO2 should be absorbed by the
oceans in order to preserve the 1:50 partitioning ratio of CO2 between air and water at earth's average
surface temperature that is governed by Henry's law.
So the
temperature of the deep
oceans (presently ~ 275K) is set by heat from inside the earth
before the sun starts warming the
surface layer.
Stephen Wilde (00:59:57) «Also one would need to observe the air circulation systems moving latitudinally
BEFORE the
ocean sea
surface temperatures change and I don't think that happens does it?»
Before we look at the causes, here are a series of detailed measurements from Near -
surface ocean temperature by Ward (2006):
If a significant portion of heat were being lost from the
ocean, then it must warm
surface air
temperatures,
before reaching the upper atmosphere and being radiated out to space.
I guess it means that most of the
ocean surface temperatures are something like 3.5 degrees C warmer than
before.
Percent change in zonally - averaged cloud cover over the
oceans as a function of latitude and height in response to an instantaneous quadrupling of CO2, decomposed into two parts: (a) a fast adjustment that occurs
before surface temperatures have warmed appreciably, and (b) a part that scales linearly with the warming of
surface temperature as the system adjusts to the increase in CO2.
Stott et al. (2007), for example, conclude that deep
ocean temperatures rose by 2 °C within a 2,000 - year time span (19,000 to 17,000 years ago) about a 1,000 years
before CO2 concentrations (and
surface temperatures) began to rise.
Similarly, Demezhko and Gornostaeva (2015) found that the heat energy change in the deep
oceans during the climate transition from the last ice age to this current interglacial occurred «2 - 3 thousands of years»
before the increases in
surface temperature and CO2, and that «the increase of carbon dioxide may be a consequence [rather than a cause] of
temperature increasing».
