title: Comment on "Absence of cooling in New Zealand and the adjacent ocean during the Younger Dryas chronozone".
abstract: Barrows et al. (Reports, 5 October 2007, p. 86) presented cosmogenic exposure dates and data from an ocean sediment core that challenge evidence for glacier advance in New Zealand during the Younger Dryas event. We use modeling of geomorphic processes to argue that their cosmogenic exposure dates are inconclusive.
