Here's something you won't want to miss:
A life-size woolly mammoth will visit Trafalgar Square on Wednesday 15 November to warn us that Britain may soon be set to suffer a peculiar and very savage climate change.
According to Chris Stringer, Research Leader in Human Origins at the Natural History Museum, within the next 50 years we may have to adjust not only to baking summers from global warning but also to mortally freezing winters - by depopulating, by changing our agricultural practices, the houses we live in, the way we live. The British way of life and Homo britannicus could go the same way as Neanderthal Man and the woolly mammoth.
Chris Stringer will be on hand in Trafalgar Square too, bringing with him a hippo's tusk found in Trafalgar Square, a mammoth's tooth and a stone tool used by Neanderthals to butcher Norfolk mammoths 60,000 years ago.
We're going along to ask Prof Stringer a bunch of scientific questions such as 'who would win in a fight to the death between a woolly mammoth and The Sultan's Elephant?'
The mammoth will be there from 9am until 4pm.
