At the global scale (i.e. across all the continents) the authors demonstrate that the agreement between the pattern of observed changes in natural systems and the pattern of observed temperature change is "exceptionally unlikely" (P<<0.01) to be due to either natural internal climate variability or natural variability of the systems themselves.
Ã€ l'Ã©chelle mondiale (c.Â­Ã Â­d. pour l'ensemble des continents), les auteurs dÃ©montrent que la concordance entre la tendance observÃ©e des changements des systÃ¨mes naturels et la tendance des changements de tempÃ©rature observÃ©s est " exceptionnellement improbable " (P<<0.01) d'Ãªtre attribuable soit Ã la variabilitÃ© naturelle du climat interne ou Ã la variabilitÃ© naturelle des systÃ¨mes euxÂ­mÃªmes.
