Using sea-level rise to define climate targets

One major consequence of global warming is the rising sea level. A study conducted at Universität Hamburg’s Cluster of Excellence for climate research CLICCS by Dr Chao Li, scientist at the Max Planck Institute for Meteorology (MPI-M) and his colleagues now shows:

if we assume that sea-level rise is the most critical effect of climate change, then it is not only more sensible, but also less expensive, to set a maximum limit for sea-level rise that corresponds to the two-degree target, rather than a temperature-based target.
