Global Warming Models Fail Forecasting Principles

Published February 4, 2013

Global warming forecasts and models produced by the United Nations Intergovernmental Panel on Climate Change fail several fundamental principles of forecasting, University of Pennsylvania professor Scott Armstrong reports today in the Washington Times.

Armstrong reports the asserted global warming crisis is similar to past environmental concerns that turned out to be overhyped. Much like global warming alarmists violate fundamental forecasting principles today, none of the past environmental alarmist movements relied on scientific forecasting methods. Nevertheless, “The government imposed regulations in 23 of the 25 alarms that involved calls for government intervention. None of the alarming forecasts turned out to be correct. Of the 23 cases involving government interventions, none were effective, and 20 caused net harm.
