so what about the millennial-scale context?

IPCC predictio

ns

too

conservative???

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 19th or early 20th 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 20th 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
