Climate modelling has produced varying projections of possible global rises in temperature. A simple statistical method brings several such projections into closer agreement and includes an indication of potential accuracy.

Governments around the world are investing heavily in coupled-climate models to project future climate change. Such models have interacting atmosphere, ocean, land and sea-ice components, and serve as laboratories for studying the effects of natural and human influences on the climate system.
