This is a short book that does one thing: it is a clear and concise explanation of climate change - how it’s happened, our part in it, what we are currently doing about it and what we need to do about it.

Why, you might ask, do we need another book on climate change?

The answer is that in December this year, in Paris, is the most important climate change conference there has ever been. It is make-or-break time, and we need to be in full possession of the facts.

We need to decide what kind of world we want to leave our grandchildren.
