Is sea level rise worse than terrorism?

Amid repeated claims of climate change alarmism from climate sceptics, a new study published in Nature Geoscience claims that sea level rise this century could be double that previously predicted by the IPCC.
This news comes amid a British Government report warning that the UK needs to treat risk of flooding with the same level of priority currently assigned to terrorism following £3 billion of flood damage in the UK this Summer.
Sceptics who once claimed that global warming didn’t exist now admit that the planet is warming, although they repeatedly tell us that current changes in climate are within ‘natural variations’. Extreme weather events have increased dramatically in the past ten years, and as global warming gets closer to home and the natural variation theory gets stretched further we hope that some old prejudices may be re-examined.
We fully appreciate that the science still has some way to go, but the evidence mounting around us every day its time we made some decisions before it’s too late.

I’ve read the paper in Nature geoscience and it doesn’t claim that sea level rise this century could be double that previously predicted by the IPCC. The paper studies estimated sea levels and rates of sea level rise during the last interglacial 125,000 years ago. Not-with-standing that the estimates come with necessarily high error bars the authors merely state that their results give an ‘observational context’ that underscores the plausibility of rates of sea level rise of 1+/-0.5m per 100 years. Wether or not sea levels in this interglacial will rise at that rate is a moot point and depends on the nature and path of climate change.
The last interglacial was different in several contexts to the present, not least of which is the more extreme warming of Greenland which is estimated to be 3 to 5 degrees C warmer than present.
