GLOBAL warming is a bigger threat to the world than Hitler, a leading historian has warned. Dr Jim Hunter told a conference on renewable energy that it would finish the job of the Highland Clearances Dr Hunter, former chairman of Highlands and Islands Enterprise, said Scottish communities would be obliterated over the next two generations by climate change. He said: 'Global warming is a more insidious and longer-term danger than Hitlerism,but it's one that could be far more deadly. Dr Hunter added that windfarm objectors in the Highland and Western Isles were missing a very serious point. He said: 'In 1940, the notion that an airbase should be resisted because of the way it would irrevocably alter the nature and the character of the community that hosted it would have seemed patently absurd. 'The Nazi threat was deemed, correctly, to be a greater hazard to our way of life than the concrete and the tarmac being spread across the landscape.' Dr Hunter, director of the UHI Centre for History in Dornoch, was speaking at a conference being hosted on the Knoydart peninsula.
