Sea Level Could Rise in South, Fall in North

Climate change is expected to cause sea levels to rise -- at least in some parts of the world. Elsewhere, the level of the ocean will actually fall. Scientists are trying to get a better picture of the complex phenomenon, which also depends on a host of natural factors.
What this article shows is the sheer complexity of climate change and how some regions will be barely affected and others potentially hard hit. Very interesting and a reminder of the dangers of the simplistic green messages which ignore the scientific evidence.

There have been several papers on this 'fingerprinting' of sea level rise over the last few years, a couple of them involving people I work with. The interesting thing in that article is where the 0m line is in the second image. For Greenland the zero line passes through the UK. However, the same chart can be drawn for the melting of WAIS and the 0m line is in the southern hemisphere.

You can also draw a similar chart based on today's rates of ice loss, expressed in mm per year. The average might be around 3 mm per year, but there's only really a single contour around the globe that actually experiences the average. Interestingly enough, hardly any coastline at all lies on that line making it hard to find paleoclimate proxies.

This may be true for sea level change alone, not for climate change as a whole. Have you considered the effects of poor harvests and hungry migrants on those areas fortunate enough to not be affected by sea level change, drought, flooding, increased crop and livestock pests and any other causes of crop failure?

Sorry, who exactly is giving simplistic messages? Other than you, I mean (see above).
