1. so what about the millennial-scale context?

2. IPCC predictions too conservative???

5.  Global sea level has remained close to stationary during the past few thousand years prior to the industrial revolution  A global acceleration of sea level started in the late 19 th or early 20 th century, reaching ~3 mm/yr during the satellite era (since 1993)  Along the central US Gulf Coast, sea level has risen 4 to 5 times faster in the 20 th century compared to the pre-industrial millennium  Sea level will very likely continue to accelerate in the next century; yet by which amount remains uncertain  The future of the US Gulf Coast depends in large part on the stability of the Greenland and West Antarctic ice sheets
