Who’s got the time these days to watch an hour-long video? Certainly not you! This one traces the attempts by a Danish scientist to discover exactly what is the relationship between clouds and cosmic rays and the magnetic activity of the sun. He searches first for theoretical evidence, then later for experimental evidence. There’s an interesting scene where Svensmark gives his presentation and is told by one in the audience that his experiment is a waste of time and not worth conducting!
