One of the most highly charged topics preoccupying the governments of the world is to be thrashed out at a UK conference starting on 1 February.

The participants, more than 200 in all, will try to agree how to define what is a danger level, and what it should be.

This, they hope, will lead to a better understanding of methods the world can employ to avoid catastrophic warming.
