Limiting global warming to 1.5°C above the pre-industrial baseline won't be enough to stop sea levels from rising by several metres over the coming centuries, according to a review of all the ...

This chart shows how much ice melt from the Antarctic ice sheet will contribute to global mean sea level increase in a scenario with +1.5°C of warming (black) vs no additional warming (dashed lines).

The primary concern is sea level rise. Levels have risen 5 millimeters a year since the 1990s, says Huw Williams, a civil engineer at Gwynedd Council, which has oversight of Fairbourne.

On average, the global sea level rises annually by about 0.14 inches, so while global warming is a very real concern you probably aren’t noticing its effects on the shoreline one year to the next.

Notes to Editors: The paper ‘Antarctic temperature and global sea level closely coupled over the past five glacial cycles’ is published by Nature Geoscience, on 21 June 2009.

Letter writer John Brock is correct that "global warming (is) not new." ("Global warming not a new phenomena," June 4). The fact that sea levels are rising is well-established and measured by "up ...
