Including the elevation effects in the model increases the estimated
sea -
level rise by a small but significant amount (5 % enhancement of melt by 2100 and 10 % by 2200 for a climate warming
scenario).
Paul D... As a part - time alarmist I would answer that with a little bit of extrapolation added to some warnings of climate scientists I guess the worst case
scenario at least
includes the total collapse of the WAIS, creating tsunamis at least all over the Pacific rim, the subsequent
sea level rise of c. 7m will destroy most of the remaining harbours, communication centers near coasts, next up would be the melting of the collapsed ice in the southern ocean altering the climate of the entire southern hemisphere, making it near - impossible to guess what areas are good for similar agriculture as before, leading to massive movements of people.
We analyzed the effect of a medium - high greenhouse gas emissions
scenario (Special Report on Emissions
Scenarios A2 in IPCC 2000) and
included updated projections of
sea -
level rise based on work by Rahmstorf (Science 315 (5810): 368, 2007).
San Francisco, in its complaint,
included a map showing water inundation for the city with 66 inches of
sea level rise plus 42 inches of flooding from a 100 - year storm, a
scenario they called «unlikely, but possible.»
The Arctic shows that tipping points for dangerous climate change and large
sea -
level rises have already been passed, a fact that the IPCC did not recognise in failing to
include any emission
scenarios for less than 2 — 2.4 ˚C in its 2007 report.
The «business as usual»
scenario outlined in the «Risky Business» research also
includes extreme
sea -
level rise, which will flood the water supply and delivery infrastructure.
Including the effects of physical mechanisms that can quickly increase ice sheet discharge significantly raises
sea level rise projections under high - emission
scenarios.
It will also confirm the accelerated rate of change for impacts such as
sea -
level rise, the steady retreat of Arctic
sea ice and quickened melting of ice sheets and glaciers, as well as offer more detail on
scenarios that will shape international negotiations over both short - term and long - term greenhouse gas emissions,
including how long «business as usual» can be sustained without dangerous risk.
Climate
scenarios of
sea level rise for the northeast Atlantic Ocean: a study
including the effects of ocean dynamics and gravity changes induced by ice melt.
Even under this highly optimistic
scenario we might see over half a meter of
sea -
level rise, with serious impacts on many coastal areas,
including coastal erosion and a greatly increased risk of flooding.
Mitigation
scenarios (also known as climate intervention or climate policy
scenarios) are defined in the TAR (Morita et al., 2001), as
scenarios that «(1)
include explicit policies and / or measures, the primary goal of which is to reduce GHG emissions (e.g., carbon taxes) and / or (2) mention no climate policies and / or measures, but assume temporal changes in GHG emission sources or drivers required to achieve particular climate targets (e.g., GHG emission
levels, GHG concentration
levels, radiative forcing
levels, temperature increase or
sea level rise limits).»
