In the past decade, new observational platforms and improved modelling of the polar climate systems have led to a quantification of recent Arctic and Antarctic climate changes and to a tentative suggestion of causality. A mounting body of literature indicates that the changes in Arctic and Antarctic climate are consistent with the human-induced warming that is occurring globally. On page 750 of this issue, Gillett and colleagues1 use an innovative attribution technique and simulations from several state-of-the-art global climate models to disentangle the internal and external forcing mechanisms that have contributed to the recently observed variability in near-surface air temperature near the poles.
