In the News & Views article 'Atmospheric Science: Winds of change' by Matthew Newman (Nature Clim. Change 3, 538–539; 2013), the words 'L'Heureux and colleagues' were missing from the sentence “The pronounced multidecadal strengthening of the Walker circulation shown by L'Heureux and colleagues is primarily linked to recent warming by association; they do not suggest a similar relationship to warming earlier in the century.” Corrected in the HTML and PDF versions after print 31 May 2013.
