«This kind of study discusses the natural cycle and could help define the likely positive feedbacks we can
expect in the long - term future, [for example] as
temperatures warm, the
ocean will want to give up more CO2, or rather absorb less,» says climatologist Gavin Schmidt of NASA's Goddard Institute of Space Studies.
As the largest contributor is
ocean thermal expansion,
warmer than
expected temperatures would be a significant part of the discrepancy.
Around 3 million years ago, when global
temperatures were about as
warm as they're
expected to be later this century,
oceans were dozens of feet higher than today.
You've got the radiative physics, the measurements of
ocean temperature and land
temperature, the changes in
ocean heat content (Hint — upwards, whereas if if was just a matter of circulation moving heat around you might
expect something more simple) and of course observed predictions such as stratospheric cooling which you don't get when
warming occurs from oceanic circulation.
He later continued: «Now that
ocean temperatures are considerably
warmer than they were a few decades ago, the maximum potential intensity a hurricane can reach is higher, and we should
expect to see a few Patricias sprinkled among the inevitable phalanxes of major hurricanes that will assault our shores in the coming decades.»
So there seem to many reasons to
expect temperatures at the bottom of the ESAS and other parts of the Arctic
Ocean to
warm in the coming years and decades.
«The global annual
temperature for combined land and
ocean surfaces for 2007 is
expected to be near 58.0 °F and would be the fifth
warmest since records began in 1880.
Soundbite version: «Global
warming is
expected to increase sea surface
temperatures, create a thicker and
warmer ocean surface layer, and increase the moisture in the atmosphere over the
oceans — all conditions that should lead to a general increase in hurricane intensity and maybe frequency.»
The paleoclimate record (8.2 kyr, and earlier «large lake collapses») shows a dramatic drop in surface
temperatures for a substantial period of time when the
ocean circulation shuts off or changes, but is that actually what would be
expected under these
warming conditions?
«The climate patterns responsible for the
expected above - normal 2007 hurricane season continue to be the ongoing multi-decadal signal (the set of oceanic and atmospheric conditions that have spawned increased Atlantic hurricane activity since 1995),
warmer - than - normal sea surface
temperatures in key areas of the Atlantic
Ocean and Caribbean Sea, and the El Nino / La Nina cycle»
Global
warming is
expected to reduce the
ocean's ability to absorb CO2, leaving more in the atmosphere... which will lead to even higher
temperatures as below from NASA.
RIGHT NOW, you are
expecting an air mass at an average 289K to more rapidly
warm a higher thermal mass of the
oceans at an average
temperature of 294.2 K.
«Even with just a further 3C of
warming — well within the range to which the UN climate science panel
expects temperatures to rise by the end of the century — nearly one - fifth of the planet's 720 world heritage sites will affected as ice sheets melt and
warming oceans expand.»
I should add that this surface
warming from anthropogenic CO2 is
expected to increase the
temperature of the
oceans which can be seen in this graph correlation http://media.web.britannica.com/eb-media/15/106515-004-540A3E17.gif
Researchers analyzed how six tropical fish species might behave in
ocean temperatures that are 2 to 3 degrees Celsius (3.6 to 5.4 degrees Fahrenheit)
warmer than their current habitats — a change that is
expected to happen by the end of this century.
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 predicted continuous
warming trend of the
ocean surface
temperature is
expected to favour the growth of smaller phytoplankton cells (picophytoplankton replacing large diatoms) that in turn would also favour small - sized zooplankton species (Li et al. 2009).
The year 2016 marked the
warmest ocean annual average
temperatures ever recorded, putting corals at risk and foreshadowing what we can
expect as climate change continues.
Importantly, these trends can largely be explained by increases in mean
ocean temperatures, suggesting that we can
expect further increases in marine heatwave days under continued global
warming.»
You'll note that the dude is clueless («Since surface
temperature ncreased significantly from 1976 to 1998, one would
expect the deep
ocean to
warm too, not because it's absorbing additional heat but because of the that increase in surface
temperature.
Loss of glacial volume in Alaska and neighboring British Columbia, Canada, currently contributes 20 % to 30 % as much surplus freshwater to the
oceans as does the Greenland Ice Sheet — about 40 to 70 gigatons per year, 66,78,63,57,64,58 comparable to 10 % of the annual discharge of the Mississippi River.79 Glaciers continue to respond to climate
warming for years to decades after
warming ceases, so ice loss is
expected to continue, even if air
temperatures were to remain at current levels.
Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the
expected influence of human - induced climate change.3 The signature of global
warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface
temperatures in the northern Pacific
Ocean.4
«in proxy data CO2 is correllated with, but lags
temperatures; the solubility of CO2 decreases with increasing
temperatures; the
oceans have
warmed, thus it is natural to
expect that CO2 has risen as a result.»
While a range of factors can contribute to
warmer seawater, both the frequency and severity of these bleaching events is
expected to increase in line with global
temperatures, as the
ocean absorbs much of the extra heat.
Hurricanes form in
warm tropical waters, drawing strength from the heat of the
ocean surface — that's why they are
expected to worsen as sea surface
temperatures increase.
The observed patterns of surface
warming,
temperature changes through the atmosphere, increases in
ocean heat content, increases in atmospheric moisture, sea level rise, and increased melting of land and sea ice also match the patterns scientists
expect to see due to rising levels of CO2 and other human - induced changes (see Question 5).
That's a key reason surface
temperatures haven't appeared to
warm as fast as many had
expected in the past ten years — although
ocean warming has sped up, and sea level rise has accelerated more than we thought, and Arctic sea ice has melted much faster than the models
expected, as have the great ice sheets in Greenland and Antarctica
And that, combined with the current record
ocean temperatures — and faster than
expected warming of the
ocean's surface layer — means we can
expect a continuation of the unexpectedly fast loss of Arctic sea ice and of land - locked ice in Greenland and Antarctica.
Of equal importance is what will happen as the
ocean warms, and what kind of changes in
ocean temperatures at the surface and at depth can be
expected?
Ultimately, the effect of dust upon hurricanes is important because, like
ocean temperatures, African dust export is
expected to change during the 21st century in response to global
warming and changes in African rainfall.
And even though
oceans are getting
warmer, water
temperatures would have to rise more and faster than
expected to produce the strongest possible storms.
