The castaway in this week's Desert Island Discs is Sir Crispin Tickell, Britain's Ambassador to the United Nations. As well as being an ambassador, he is also a passionate meteorologist and conservationist - a cool diplomat who's made himself an expert on global warming. He'll be talking to Sue Lawley about his many postings, passions and pastimes.
