Trying to predict climate change is hard. There are lots of factors involved – air temperature, sea temperature and cloud cover all play a part – as do dozens of other variables. Therefore, there are a huge number of calculations involved.
One solution is for scientists to use the largest supercomputer they can find. But even the biggest supercomputers are only so good.
We think you can do better.
Using a technique known as distributed computing, we’re hoping to harness the power of thousands of PCs around the world. If 10,000 people sign up, we’ll be faster than the world’s biggest computer. And we’re hoping to be even better than that.
However, if you want to, you can follow the progress of your experiment on a 3D spinning globe.
Take part in the experiment
Donate your spare computing power and take part in the world's largest climate experiment. Find out why we need your help, and what we are hoping to find out.
