The planet could face sea levels 30 cms higher in 80 years.<\/p>\n<p>While 2018 was probably only the fourth warmest year for global surface temperatures, it is <a href=\"https:\/\/www.eurekalert.org\/pub_releases\/2019-01\/uoc--oaw010919.php\">likely to have been the hottest year ever for the oceans<\/a>. The previous such year was 2017, and before that 2016.<\/p>\n<p>And if global warming follows the pattern predicted by computer simulations, then at present rates the extra temperature of the oceans will cause a thermal expansion \u2013 warm water is always less dense than cold water \u2013 by <a href=\"https:\/\/www.eurekalert.org\/emb_releases\/2019-01\/ioap-owi010319.php\">30 centimetres by the end of the century<\/a>.<\/p>\n<p>That is 30cms of sea level rise on top of all the extra rising sea water delivered by melting ice caps and glaciers on the world\u2019s continents.<\/p>\n<blockquote><p><strong>\u201cThe need to slow or stop the rates of climate change and prepare for the expected impacts is increasingly evident\u201d<\/strong><\/p><\/blockquote>\n<p>The planet is 71% ocean and the clear blue water absorbs an estimated 93% of all the excess heat trapped by the greenhouse gases emitted by humans as they burn fossil fuels to power the global economy.<\/p>\n<p>And a quartet of scientists from China and the US calculate that if the world goes on burning fossil fuels under the notorious business-as-usual scenario, then by the end of the century the top 2,000 metres of the high seas will have warmed by 0.78\u00b0C, causing 30cms of sea level rise simply by ocean expansion.<\/p>\n<p>\u2026click on the above link to read the rest of the article\u2026<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Warming may mean sea levels 30 cms higher An Irish railway station, built with sea level rise in mind.
