climateprediction.net applies distributed computing to climate science by running thousands of perturbed climate simulations on volunteer computers worldwide. Each simulation varies uncertain physical parameters within plausible ranges, enabling probabilistic climate prediction through ensemble statistics. | climateprediction.net applies distributed computing to climate science by running thousands of perturbed climate simulations on volunteer computers worldwide.
