Statistical forecasting: how fast will future warming be?

A new paper published by the Global Warming Policy Foundation explains how statistical forecasting methods can provide an important contrast to climate model-based predictions of future global warming. The repeated failures of economic models to generate accurate predictions has taught many economists a healthy scepticism about the ability of their own models, regardless of how complex, to provide reliable forecasts. Statistical forecasting has proven in many cases to be a superior alternative. Like the economy, the climate is a deeply complex system that defies simple representation. Climate modelling thus faces similar problems. This paper explains how statistical time-series forecasting methods are being applied to climatic processes.
