07/15/2013 - Greenhouse gases emitted today will cause sea level to rise
for centuries to come. Each degree of global warming is likely to raise
sea level by more than 2 meters in the future, a study now published in
the Proceedings of the National Academy of Sciences shows. While
thermal expansion of the ocean and melting mountain glaciers are the
most important factors causing sea-level change today, the Greenland and
Antarctic ice sheets will be the dominant contributors within the next
two millennia, according to the findings. Half of that rise might come
from ice-loss in Antarctica which is currently contributing less than 10
percent to global sea-level rise.
