hot off press from New Zealand: my island house is doomed

Hi Jim,

In 20 years there may not be very big sea impacts of sea level rise except in some very low, flat places. It is only 3 mm/yr global now, or a bit more than an inch per decade, so 2" in 20 years. Not going to have a huge impact in a place with such large tide range. And, I checked the tide gauge record for Newport, Rhode Island (next island over) and there is no acceleration of rise yet. So, for now, local effects can outweigh global effects. Hey, one big quake with uplift rather than subsidence would cause a local (relative) sea level drop!

What is unclear is how fast the acceleration of sea level rise will be. Will it every get to 30 mm/year? When? 10 mm/yr?

Chris
