In our paper describing a new coral record from Butaritari, we hypothesized that comparing the temporal trends in our records to coral records from farther east in the equatorial Pacific may support the evidence for a weakening of a Walker circulation, documented elsewhere in the literature [Power and Smith, 2007; Tokinaga et al., 2012]. Weakening of the Walker circulation is expected under global warming due to an imbalance in the rate of change in different aspects of the hydrological cycle [Vecchi and Soden, 2007].
provide additional analyses, which confirm that our reconstruction [Carilli et al., 2014] shows a long-term
weakening of the Walker circulation over 1972–1998. We also document that significant decadal variations
in Walker circulation strength, and for particular choices of start and end years over which trends are
calculated, are able to show slight Walker strengthening. Overall, we conclude that Walker circulation
variations are more nuanced than either our original publication [Carilli et al., 2014] or the subsequent
Karnauskas et al.  comment would suggest. Karnauskas et al.  also provide a detailed analysis
of Equatorial Undercurrent (EUC) activity near the Gilbert Islands and argue that the EUC does not strongly
affect Butaritari. Our original publication did not claim to find significant EUC/Butaritari linkages, and we
appreciate the diligence of Karnauskas et al.  for ruling this out as a possibility.
