Measurements have been averaging a little above 3mm per year for the last two decades[0]. This is believed to be about double the post-Ice-Age background rate of a century ago, and it is predicted to accelerate further (though it has yet to do so noticeably).

- godshatter 9y agoIn fact, that same graph used to have a trend line of 3.2 mm/yr, and is now 3.1. I've been checking in with that site off-and-on for the last few years. At the current linear rate, we're looking at an increase of 0.25m by 2100. To get to the 1m by 2100 that is predicted, we would have to have a linear sea level rise of 12.4 mm/yr. The graph displayed shows some variable years a few years ago, but it's mostly been pretty linear. The graph shows 20 years or so of data, and we're 82 years out from 2100. I would expect to see it curving up sometime soon, but it hasn't done that yet.
