Skeptical Testimony: Forecasting Expert Prof. J. Scott Armstrong audited IPCC’s temperature forecasting procedures and found they ‘violated 81% of the 89 relevant forecasting principles’
The warmists 'argument for predictive validity is based on their claim that nearly all scientists agree with forecasts...errors for IPCC model long-term forecasts were 12.6 times larger than 'no change' model...'We have identified 26 historical alarmist movements. None of forecasts for alarm proved correct. In the 25 alarms that called for gov't intervention, gov't imposed regulations in 23. None of 23 interventions was effective and harm was caused by 20 of them'
