Response to Comment on “Review of Methane MitigationTechnologies with Application to Rapid Release of Methane from theArctic”
In our paper, “Review of Methane Mitigation Technologieswith Application to Rapid Release of Methane from the
Arctic” we attempted to lay the groundwork for a new field ofinquiry into Arctic methane mitigation. Part of that effort wasto catalog the mitigation options that have been proposed todate, which include, for example, microbubbles to whiten andcool Arctic waters and water management to reduce emissionsfrom Arctic wetlands.Mr. Lockley’s comment on our paper describes additional
mitigation options to those that we cataloged. It is worth notingthat his suggestions, and many of ours, are still little more thannotions at this stage. However, with the menu of options nowlaid out, we can begin to evaluate them and systemicallydetermine the most promising strategies.A sensible approach to the Arctic methane threat should
continue to emphasize environmental monitoring and climatescience since large uncertainties remain about the quantity andmechanism of methane release. However, the risk is clearenough that a dedicated research effort on Arctic methanemitigation is warranted. We hope that the options that we andMr. Lockley have identified can now be investigated in detail.
