Reviewer 2 Report

The study examines interannual variability of the Earth's rotation as an indicator of climate change. It is premised on the assessment of Elnino and Lanina events over a +/- 47 year period. A lot of similar/ related studies have been conducted. Though limited in novelty, the study is very important as it contributes significantly to our understanding of the climate system from the perspective of geophysical processes.

This work is well thought out and presented. Congratulations to the authors. However, before the work is accepted for publication, the authors need to provide a detailed and convincing analogy of how the data sets were treated to deal with auto-correlations and other noise which come naturally with data. Pre-whitening of data is important in trend analysis, hence the authors need to be clear on how this was done.

Determination of the margin of error is also very key. The authors need to make sure this is clearly explained in the methodology. Just a few grammatical issues need your attention as well. 

 

The quality of English Language is good. Very minor corrections are required.

 

Reviewer 3 Report

General Comment: The research provide good analysis in terms of how extreme events affect Earth’s rotation, specifically ENSO. However, it seems that the analysis is quite unbalance. More attention and deeper analysis was provided to address La Nina Impact. Since El Nino extreme is also predicted to be more common in the future, It seems that deeper analysis and explanation need to be added especially when the prediction is given for El Nino year.

The research uses different method of citation in text and reference. While the text uses numeric system reference, there are no number in reference. Thus, it is hard to confirm the citation.

Some of the grammar errors need to be corrected
