Warming the surface mixed later alone to such a degree could drive roughly an inch of sea level rise a year - which is in the middle of the modeled
range of projections for runaway AGW - but that is not a prediction because it wound require implausible rates of increase in fossil fuel burning
So they're sure to come up with an
exciting range of projections and options, modelled on state - of - the - art equipment, paid for by you and me.
It was already well known that it is possible to envisage models that match recent observations but which have a
broader range of projections than the CMIP models.
As the press release states, «his film and video installations involve specially designed architecture, built to contain
a range of projection devices that create specific viewing conditions for each work.»
Still, our understanding has a wide
range of projections, particularly for high emissions scenarios as Jevrejeva et al. (2014) illustrates.
For these reasons,
a range of projections of future climate change has been conducted using coupled AOGCMs.
Ed Hawkins, of the University of Reading, in Britain, points out that surface temperatures since 2005 are already at the low end of
the range of projections derived from 20 climate models.
We would note we are only using the opposite ends of
the ranges of projections from industry, analyst or government sources to test the potential for change.
Sea levels will likely be greater than
the range of projections, but we can't be sure by how much until more data can be gathered about the effect of global warming on ice flows.
In October, Bloomberg Business published a chart summarizing
the range of projections, which also included the International Energy Agency's (IEA) projection that — in Bloomberg's words — «temperatures were likely to rise by 2.6 degrees Celsius by 2100, and by 3.5 degrees Celsius a century later»:
