@thingsbreak No. 0.06% is reduction in annual *growth* rate (from say 2% to 1.94%/yr). Cumulates over time: -1.2% in 2030 (1.0006^20) etc.

Huh? The cumulative, over 20 years (2034, not 2030), of 0.06% would be .2%, not 1.2%. @BjornLomborg @thingsbreak In 2070 (56 years), .34%.

@A_Siegel @thingsbreak AR5 WGIII SPM p.18: 2% growth over 2010-30=48.6% growth (1.02^20). 1.94% growth=46.9%. Cost in 2030: 46.9-48.6=-1.7%

IPCC mitigation cost: -0.06% GDP growth rate. That's -1.2% GDP in 2030, -2.3% in 2050, -3.5% in 2070 @BjornLomborg @A_Siegel @thingsbreak

@simondonner @A_Siegel @thingsbreak Simon, yes, for 0.06% (though higher with 2% growth overlay). But high-end is 0.14% growth reduction

@BjornLomborg @A_Siegel @thingsbreak Yes, but still not -6% in 2050. It is -5.3%, starting from 2010; -4.8% from this year.
