RON Meldrum of the Green Party [Echo Letters, January 7] makes some sensational claims. 

He writes that sea level rose by a foot in the last century. But before the United Nations started the great global warming scare 30 years ago, oceanographers said the rise was at the most an inch. 

After the great scare began, leaders of the Maldives, the lowest lying islands in the world, started asking the world for huge sums of money for sea defences against the rising Indian Ocean.

However Professor Nils-Axel Morner, chairman of the International Commission On Sea Level Change [ICSLC], part of the International Union For Quaternary Research [INQUA], visited the Maldives six times with ICSLC experts, on a special INQUA project. He found that the sea level there had not risen for half a century. 

The leaders of the low lying Maldives had been lying. An inch, not a foot, Ron.

In this century Ron says that sea levels will rise by three feet, which will put half of Holland permanently under water, and it will be all our fault for not being green. 

That sounds less threatening than his ‘Act now to save planet’ letter of late last year, when he wrote that Theresa May must make plans now, to resettle 20 to 30 million people in Britain, who will be flooded out by rising seas. 

Sometimes you wonder what planet Green Party people are on.
