Mathematics of Planet Earth

It is a Chinese curse that you should 'live in interesting times'. 
These are times when things are changing quickly, and often not for the 
better. But why do we have both boring times when nothing much happens 
and interesting times with a lot of change.

In this talk Professor Budd will look at why things can change quickly 
and why this matters. He will look at examples including power cuts, 
climate change and events from history. The lecture will, quite literally,
upset the apple cart.
