At the other end of the spectrum are huge software models that simulate incredibly detailed processes at high speed. An example of these are the Global Climate Models (GCMs) which simulate the trajectory of the earth’s climate over the coming decades, used by the Intergovernmental Panel on Climate Change (IPCC) to prepare its periodic assessment reports on the current threat of climate change.
