Telling little green lies?

The hole in the ozone layer has more to do with politics than deodorants, a French scientist tells Ian Phillips.

If there is one thing Haroun Tazieff believes in, it is speaking his mind. "When I've got something to say, I say it," he asserts. In the past, France's most famous volcano expert has raged about everything from the Mafia to television presenters, but in recent years he has found a new hobby-horse - the ecological lies he believes Green politicians have invented to scare the electorate into voting for them.

Things that go bump in the night!

North island, New Zealand
Every year in my introductory geology course I cover topics on volcanic activity and on earthquakes, and every year, almost without exception, nature obliges me with some excellent practical examples.
