Phys. Rev. Lett. 89, 028501 (2002) [4 pages]Global Climate Models Violate Scaling of the Observed Atmospheric VariabilityReceived 1 November 2001; revised 22 April 2002; published 21 June 2002 We test the scaling performance of seven leading global climate models by using detrended fluctuation analysis. We analyze temperature records of six representative sites around the globe simulated by the models, for two different scenarios: (i) with greenhouse gas forcing only and (ii) with greenhouse gas plus aerosol forcing. We find that the simulated records for both scenarios fail to reproduce the universal scaling behavior of the observed records and display wide performance differences. The deviations from the scaling behavior are more pronounced in the first scenario, where also the trends are clearly overestimated. © 2002 The American Physical Society URL:
