Be part of the biggest climate change experiment in the world.
The BBC have just started a new project to harness the power of thousands of home PCs to build a supercomputer that can help create simulations of how climate change will affect the world.
The PCs will enable environmental scientists to run multiple experiments that will combine to give them a more accurate prediction of climate change.
