Climate Change from the BBC Weather Centre aims to inform people about the potential changes in our weather in the coming 100 years. The site explains what climate change is and the part the greenhouse effect plays in it. It looks at the evidence that indicates our climate is already getting warmer and wetter, the impact this will have on our lives and the way we need to adapt to deal with it - in the ways we build our homes and the sources from which we get our energy. Climate Change also explains the negotiations made between politicians around the world - such as at the Kyoto Protocol and the Delhi Declaration.

magine you live in a timber shack in Alaska. It's chilly up there, so you build yourself a huge log fire and pile on all the wood you can find. To start with, the fire seems a great idea—especially since it's so cold outside. The shack warms up slowly, but predictably, and it's soon pretty cosy. Since the shack is much warmer than the atmosphere and ground that surround it, it loses heat quite quickly. If the fire supplies heat at the same rate as the shack loses it, the shack stays at roughly the same temperature. But if you make the fire too big, the shack will get hotter... and hotter... and hotter. Before long, you'll start feeling uncomfortable. You might wish you'd never made the fire so big in the first place. But once it's burning, there's nothing you can do to stop it. The shack will keep getting hotter long after you stop piling wood on the fire.
