Eminent geographer Professor David Livingstone wants us to see that climate is more than just the weather outside our window - it's an empire that has shaped our lives throughout history.

In the Western world, we live very cushioned lives, so that climate rarely impacts on us in a disastrous fashion. When it does - like the floods that hit parts of the UK in 2007 - we're left shocked and surprised by the ferocity of what climate can do. David explores the way human beings are shaped by weather patterns; "climate has always been a moral issue - not just a description of the weather" he says.
