Climate change campaigner and former US vice-president Al Gore has hailed Scotland as a world leader in renewable energy.
He was speaking at the Scottish Low Carbon Investment Conference in Edinburgh.
Mr Gore spoke at length on the catastrophe he claims the world is facing if steps are not taken to reduce carbon emissions.
He said: “Scotland has unique opportunities with the natural resources, including the incredible percentage of the offshore wind resource and the excitement of the potential of wave and tide energy, although that’s at an earlier stage of investigation and development.”
There was only one dissenting voice in the question-and-answer session that followed Mr Gore’s speech.
Tory Edinburgh councillor Cameron Rose queried the consensus on climate change.
However, Mr Gore responded by saying a man with chest pains would take the health advice of 98 doctors and ignore the two who said there is nothing to worry about.
First Minister Alex Salmond said: “We face a moral obligation to act against growing climate chaos and a clear economic imperative to avoid much greater future costs and these are issues which Mr Gore has worked tirelessly and consistently to communicate to governments, corporations and citizens across the world.
“His leadership in this area can provide great encouragement and impetus to delegates attending this week’s conference as we work together to build a sustainable future for the planet and for the generations that follow us.”
