AEI, in association with The Economist magazine, is pleased to announce the Institute's Second Annual Climate Policy Conference. The conference will convene international panels of experts to examine the controversy over emissions forecasting scenarios and methods. The fundamental input of climate change models is derived from forecasts of future emissions of greenhouse gases, but in recent years there has been considerable discussion and dispute over the economic foundation of these scenarios. This conference will review the uncertainties of emissions forecasting, with an eye toward highlighting "best practices" that might be used to refine future climate change forecasts.
