Letters: No climate crisis

I HAVE two papers. The first one shows a photograph of an American nuclear submarine in open water at the North Pole. The date is 1958. The other is a graph of the latest analysis of Greenland ice core samples going back 8,000 years. This shows six warmer periods before this century. I already knew about four.

They are the Holocene Climatic Optimum, the Minoan Warm Period, the Roman Warm period and the Medieval Warm Period. There were another two which were unnamed. During the Holocene Climatic Optimum, the Sahara was a land of lakes and streams, teeming with wildlife. The remains of some of the Stone Age settlements were shown recently in the National Geographic magazine.

This knowledge should put an end to the present-day scares.

Nick Dekker (Letters, 2 September) raises a moot point in his example extracted from the Neta website, regarding the inputs to national energy supplies from renewables. We would be better placed to judge the "myths and mists" propounded by the renewable energy caballists if we (especially the Scottish Government) looked at its contents.

Would anyone from the cabal like to tell us how many tens of thousands of wind and tidal turbines will be required to replace fossil fuel and nuclear sources, where we are going to put them and how many glacial glens in the Highlands will have to be dammed to provide back- up?
