of the Antarctic Ice Sheet will be governed more by long - term anthropogenic
warming combined with multi-centennial natural variability than by annual or decadal climate oscillations.»
Volume, in contrast, is crucial in determining the vulnerability
of Arctic sea ice to rapid
future reductions (since thin ice is much more prone to react strongly to a single
warm summer, making single very - low sea - ice summers more likely), and the thickness
of the ice determines the exchange
of heat between
ocean and atmosphere.
Certainly
future ocean warming from increasing levels
of greenhouse gases is reasonable to expect.
I'm not sure I totally understand this post, but if the
ocean has cooled slightly as part
of natural fluctuation «noise,» and if last year's hurricane season (with Katrina, et al.) happened during this natural cooling fluctuation, and if the
ocean is on a general track
of getting
warmer, then we probably have much much worse to expect in
future hurricanes....
Even with these possible issues, it buys us 50 years

In Northeast Land and Svalbard, the melting waters on the ice caps are the tears
of the Earth mourning the
future death
of men and civilizations as the concentration
of carbon dioxide in the atmosphere spikes and global
warming proceeds rapidly, killing millions
of marine organisms, and increasing the acidification
of the
oceans.
Part
of problem is that even with current levels
of emissions, the inertia
of the climate system means that not all
of the
warming those emissions will cause has happened yet — a certain amount is «in the pipeline» and will only rear its head in the
future, because the
ocean absorbs some
of the heat, delaying the inherent atmospheric
warming for decades to centuries.
At the moment, the
oceans are absorbing about a third
of the carbon dioxide we are emitting, but scientists are unclear whether it will continue to do so in the
future, as the

It's very clear (thanks to Steve M, Willis etc) that there are issues with both but given the current hyped claim by the «
warmers» that the past effects
of man - caused global
warming have largely been masked by the
warming of the
oceans and that unless we reduce CO2 emissions now that we won't be able to mitigate
future global
warming when this «stored heat» eventually comes back out
of the
oceans and leads to catastrophic effects, I'm very interested in getting to the punchline
of this debate on SSTs.
«a slowdown in the MOC is predicted by our model (and others) for a
future world, partly as a function
of ocean warming and partly as a function
of increased freshening from ice melt and increased rainfall.
There is new information that lack
of sea ice causes storms to produce larger waves and more coastal erosion.5 An additional contributing factor is that coastal bluffs that were «cemented» by permafrost are beginning to thaw in response to
warmer air and
ocean waters, and are therefore more vulnerable to erosion.22 Standard defensive adaptation strategies to protect coastal communities from erosion such as use
of rock walls, sandbags, and riprap have been largely unsuccessful.23 There remains considerable uncertainty, however, about the spatial patterns
of future coastal erosion.
But the
future climate
of West Antarctica is uncertain, and the physical factors that govern the collapse
of outlet glaciers like Thwaites are poorly understood — in particular, a peculiar glacier instability mechanism likely triggered by
warming ocean waters in a changing climate.
All such projections involve assumptions about the
future that can not be tested, so the authors spread their bets: they considered a range
of scenarios involving crude population growth, levels
of economic growth with time, and a series
of predictions
of sea level rise, as icecaps and glaciers melt, and as the
oceans warm and expand according to predictable physical laws.
