In the Commentary 'Characterizing loss and damage from climate change' (Nature Clim. Change 4, 938–939; 2014) it is incorrectly implied that the UNFCCC has an official definition for loss and damage. Whilst the definition is correctly quoted from a UNFCCC literature review, this was a working definition for the purpose of that review. There has been no formal discussion under the UNFCCC on what the term 'loss and damage' signifies. This correction notice has been published after print 7 January 2015.
