Al Gore, climate change and the art of the possible

Al Gore has done a great deal to raise awareness of global warming. He failed in his bid to become President of the United States but succeeded in publicising “An Inconvenient Truth” which reached millions of people with its message. Mr Gore succeeded in either creating or adopting a phrase which grasped hold of the imagination and it did not matter too much that his book and his film contained some inaccuracies, or that the title itself portrayed as simple truth what is a complex interweaving of postulations.
