Van Meter (Reports, 27 April 2018, p. 427) warn that achieving nitrogen reduction goals in the Gulf of Mexico will take decades as a result of legacy nitrogen effects. We discuss limitations of the modeling approach and demonstrate that legacy effects ranging from a few years to decades are equally consistent with observations. The presented time scales for system recovery are therefore highly uncertain.
范米特（《报告》，2018年4月27日，第427页）警告说，由于遗留氮的影响，要在墨西哥湾实现氮减排目标需要数十年时间。我们讨论了建模方法的局限性，并证明从几年到几十年的遗留效应同样与观测结果相符。因此，所提出的系统恢复时间尺度具有高度不确定性。
