In our paper published last night in ERL we show the newer Church & White data set with less smoothing in Fig. 3 (orange line), and you can see it is more «wiggly» — hard to tell whether these wiggles are true oscillations in global sea level or again an effect of the limited number of gauges.

Satellite data now shows we are witnessing a very rapid acceleration in global sea level rise.

Past studies still foresaw a heavy melt, but it led to an increase in global sea levels of around 2 centimeters, not the 3.5 of this new, more precise study.

Even as negotiators meet in Marrakech, Morocco to take the next steps to avert dangerous human - caused climate change — and, even as the U.S. decides whether or not to elect a president who is skeptical it is happening — a new study has highlighted the sharp stakes involved, particularly when it comes to the ongoing rise in global sea level and the dramatic but uneven way in which it could affect the world's coastlines.

Since 1995, researchers found that Greenland has lost a total of about 4,000 gigatons of ice, which has become the biggest single contributor to the rise in global sea levels.

The findings have implications for the wave environment of the Southern Ocean and, potentially, for factors driving the collapse of ice shelves, which can lead to an accelerated increase in global sea level.

This is a particularly useful region because the oxygen isotopic composition of the seawater is largely determined by the flow of water through the Strait of Gibraltar, which in turn is sensitive to changes in global sea level — in a way like the pinching of a hosepipe.
