how thatcher went green

In Radio 4's Uncertain Climate we learn how Sir Crispin Tickell explained climate change to Prime Minister Margaret Thatcher on a flight back from Paris to London.

Tickell had been at the same school, Westminster, with the Chancellor of the Exchequer, Nigel Lawson.

(Lawson, a doubter then as now, thought Tickell's exposition on climate change was just "Crispin being Crispin".)
