The BBC is conducting a vast experiment in climate change and you can take part!
Basically they need you to download the software that will allow you to run a weather model, to help predict what will happen to the weather in the future. The software runs in the background so you use your computer normally. Thousands of participants are needed in order to run as many models as possible, with each one being slightly different to take account of the millions of variables. Remember that 10,000 computers are equal to the worlds most powerful super computer and the beeb wants many more than this.
So if you are serious about global warming now is your chance to help find out what is really happening.
