Key assumptions
This module is based on uses a linear algorithm developed by Rahmstorf, based on extrapolating from increases in temperature and sea level that occurred from between 1881 -and 2001.
This approach was chosen because, according to Rahmstorf the "capability for calculating future sea-level changes...with present physics based models is very limited."
...
- Baseline annual increase in sea level of 3.4 millimeters for each degree Celsius by which GMT in that year exceeds pre-industrial levels (C-LEARN uses this baseline parameter in all of its outputs).
- User-specified parameter which that enables adjustment of baseline annual increase to take into account faster or slower ice sheet melt (this parameter is adjustable in C-ROADS but not in C-LEARN).
Parameter value of 1 doubles annual sea level increase per degree of increase in GMT to 6.8 mm per degree Celsius increase in GMT .
Parameter value of -1 reduces annual sea level increase to 0 mm.
