Given the impacts of adding 120 meters equivalent of global
mean sea level equivalent of freshwater to the system are unlikely to be negligible on ocean circulation and biological activity.
Not exact matches
People's beliefs tend to align neatly with their interests, and in the absence of indisputable proof (and to non-scientists that
means the
equivalent of a ten - foot rise in
sea level inundating South Beach) it is more «convenient» for people to use cheap oil, natural gas and coal.
The contribution from glaciers and ice caps (not including Greenland and Antarctica), on the other hand, is computed from a simple empirical formula linking global
mean temperature to mass loss (
equivalent to a rate of
sea level rise), based on observed data from 1963 to 2003.
That would likely
mean that also the official UN climate goal of limiting the average world temperature rise to no more than 2 degrees Celsius — a target linked to 450 ppm CO2
equivalent stabilisation scenarios (practically ambitious, theoretically weak)-- will eventually lead to many meters of global
sea level rise.
West Antarctica loses an amount of water weight
equivalent to Mount Everest every two years and this could
mean that
sea level could rise by about by 3 feet in 2100.
Based on ice - sheet model simulations consistent with elevation changes derived from a new Greenland ice core, the Greenland ice sheet very likely contributed between 1.4 m and 4.3 m
sea level equivalent, implying with medium confidence a contribution from the Antarctic ice sheet to the global
mean sea level during the last interglacial period.
For instance: I was looking at what the AMSU instruments (http://discover.itsc.uah.edu/amsutemps) at
sea -
level are showing and their
equivalent temperature has always hovered about 294.75 K ± 0.25 K for global average, not 288 as Trenberth assumes as the
mean global average temperature of the surface, so, just change it and see the effect.
