The significant difference between the observed decrease of the CO2 sink estimated by the inversion (0.03 PgC / y per decade) and the expected increase
due solely to
rising atmospheric CO2 -LRB--0.05 PgC / y per decade) indicates that there has been a relative weakening of the Southern
Ocean CO2 sink (0.08 PgC / y per decade)
due to changes in other atmospheric forcing (winds, surface air
temperature, and water fluxes).
Spatial variability of the rates of sea level
rise is mostly
due to non-uniform changes in
temperature and salinity and related to changes in the

due to coral bleaching.
Rising population and over-grazing by livestock was the first theory but studies now show the drought resulted from changes in
ocean surface
temperatures Folland et al (1986) Giannini et al (2003) which are likely
due in part to the sulphate aerosol pollution of Europe and North America Rotstayn & Lohmann (2002) Biasutti & Gainnini (2006) and thus it is the cleaning of emissions from power stations that has likely allowed the rains to return.

Hayden proposes that this is explained by assuming that the CO2 levels are
due to
ocean emissions, which
rise with
temperature.
To say nothing of the warming trends also noticed in, for example: *
ocean heat content * wasting glaciers * Greenland and West Antarctic ice sheet mass loss * sea level
rise due to all of the above * sea surface
temperatures * borehole
temperatures * troposphere warming (with stratosphere cooling) * Arctic sea ice reductions in volume and extent * permafrost thawing * ecosystem shifts involving plants, animals and insects
In addition, multidecadal measurements of steric sea level
rise (a
rise due to thermal expansion of sea water), and of
ocean heat content have also been consistent with the
temperature trends.
Between 1910 and 1940 global atmospheric
temperature rose by 0.5 C (probably
due to increased CO2 concentration), we should not be surprised when this heat reappears 40 years later in the
oceans.
One of the important points for the actual dispute is if the increase of evaporation from the surface of the
oceans prevents the
rise of
temperature of
oceans, which would be expected
due to the increase of the back radiation (which, in turn, is
due to the change of the composition of the atmosphere).
Uncertainty in these projections
due to potential future climate change effects on the
ocean carbon cycle (mainly through changes in
temperature,
ocean stratification and marine biological production and re-mineralization; see Box 7.3) are small compared to the direct effect of
rising atmospheric CO2 from anthropogenic emissions.
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).
Vincentrj # 28 you are unclear re the division of your opinions / inferences between the 3 basic sub-topics (1) heat is entering the
oceans due to radiative imbalance
due to humans burning carbon fuels (2) the heat rate coupled with its estimated duration (based on its cause) will make it within a few decades become unprecedented during the last several thousand years and same for the surface
temperature rise that will be required to stop it (3) the effects on flora & fauna will be highly negative even within this century and more so for centuries and millenia thereafter, in particular the human species which has softened much and expects much more since the days when a mammoth tusk through the groin was met with «well Og's had it, press on».

As far as
rising ocean temperatures are concerned, I know studies (like Barnett et al 2005) demonstrated there is an anthropogenic signal (if I am using the term correctly, meaning a discernable increase in
ocean temperature that is
due to human activities) globally.
In some of the tropical
oceans where reef - building corals live
temperatures rose above average tropical

RealClimate is wonderful, and an excellent source of reliable information.As I've said before, methane is an extremely dangerous component to global warming.Comment # 20 is correct.There is a sharp melting point to frozen methane.A huge increase in the release of methane could happen within the next 50 years.At what point in the Earth's
temperature rise and the
rise of co2 would a huge methane melt occur?No one has answered that definitive issue.If I ask you all at what point would huge amounts of extra methane start melting, i.e at what
temperature rise of the
ocean near the Artic methane ice deposits would the methane melt, or at what point in the
rise of co2 concentrations in the atmosphere would the methane melt, I believe that no one could currently tell me the actual answer as to where the sharp melting point exists.Of course, once that tipping point has been reached, and billions of tons of methane outgass from what had been locked stores of methane, locked away for an eternity, it is exactly the same as the burning of stored fossil fuels which have been stored for an eternity as well.And even though methane does not have as long a life as co2, while it is around in the air it can cause other tipping points, i.e. permafrost melting, to arrive much sooner.I will reiterate what I've said before on this and other sites.Methane is a hugely underreported, underestimated risk.How about RealClimate attempts to model exactly what would happen to other tipping points, such as the melting permafrost, if indeed a huge increase in the melting of the methal hydrate ice WERE to occur within the next 50 years.My amateur guess is that the huge, albeit temporary, increase in methane over even three or four decades might push other relevent tipping points to arrive much, much, sooner than they normally would, thereby vastly incresing negative feedback mechanisms.We KNOW that quick, huge, changes occured in the Earth's climate in the past.See other relevent posts in the past from Realclimate.Climate often does not change slowly, but undergoes huge, quick, changes periodically,
due to negative feedbacks accumulating, and tipping the climate to a quick change.Why should the danger from huge potential methane releases be vievwed with any less trepidation?
As Media Matters has noted, the IPCC's 2007 «Synthesis Report» concluded that» [w] arming of the climate system is unequivocal, as is now evident from observations of increases in global average air and
ocean temperatures, widespread melting of snow and ice and
rising global average sea level» and that» [m] ost of the observed increase in global average
temperatures since the mid-20th century is very likely [defined in the report as a» > 90 %» probability]
due to the observed increase in anthropogenic [human - caused] GHG [greenhouse gas] concentrations.»

Oceans absorb CO2 so sea level
rise is good - Not when most of the sea level
rise is
due to thermal expansion and the rate of CO2 absorption decreases as
temperature increases.
