Dear Maria and co-authors,

Thank you for your resubmission of your manuscript. I have carefully read your manuscript and your reply to the review. The paper has clearly improved. However the following issues should be considered prior to publication:
- Include the calculated uncertainty to all relevant numbers and not only to the per cent change. Please also do so for table 2 (and 4) as requested by a reviewer. Do not show two decimal digits for numbers where not needed (especially for values >10.0 km²) as this implies an accuracy which is not true (e.g. abstract L. 18, Tables 2 and 4).
- You mainly present information about area and length changes. Area and length changes are, as you write correctly in lines 435ff, a delayed signal to climate. This fact has to be mentioned earlier and better taken into account when presenting and discussing the climate data.
- L. 113: You write later that you used pansharpend Landsat images. Please state here if you used the 15 m panchromatic images or the pansharpened multispectral images.
- L. 124: This justification not to use Corona is a weak one. Even if the theoretical error would be comparable with the signal you can likely see changes. Either provide a better justification or omit.
- L. 126: Provide more information about the “preliminary assessments”. What have you done? Is the data from Katalog Lednikov and WGI different? If not, please state so.
- L. 165: Provide more information why extensive manual corrections are required when automatically mapping small glaciers (see e.g. Paul et al. 2013 as cited few lines above; you may also interested to read Fischer et al. 2014)
- L. 187/189: Repetition of “was applied”.
- L. 194f: You need not to cite two times a work by F. Paul as the method used for both studies is the same. Rather refer to Schiefer et al. (2008) or Bolch et al. (2010, which is anyway cited in the manuscript) who present a different and more automated approach.
- L. 198f. The reviewer stated that it would be interesting to know the effect on area changes when including the surging glaciers. I agree that the area changes of these glaciers are not forced by climate. However, the information about the area changes is a very valuable asset to this paper and could easily be calculated for the 7 glaciers.
- L. 235: “Most debris-covered glacier snouts do not merge with periglacial landforms” Be more precise.
- L. 269ff: It would be suitable to consider here Hall et al. (2003)
- L. 314: The fact that the smallest glaciers show the lowest relative change is interesting. Put a bit more emphasis on this fact especially in the discussion. Is this true for both regions? Is it due to topographic effects?
- L. 396. Paul et al. (2004) used Landsat not ASTER images.
- L. 400. It would be appropriate to cite Paul et al. (2013) also here.
- L. 448: It would be interesting to mention here also the recent study by Fischer et al. (2014) who investigated are change in the Swiss Alps until 2010.
- Please provide a conclusion at the end of the study and not a summary.
- Figure 1: This is not a good use of space. Reduce the white space and the size of the coordinates. Position the coordinates as you did in Figs. 4 and 5. The real area of interest would then be better visible without using more space.
- Fig. 5. Include a scale bar.

The revision should contain a response to each of the comments and explain how the comment was handled. If you disagree with a comment, please explain why. If the text was modified as a response to a comment, please indicate how the text was modified and highlight the changes in the manuscript.
Please do not hesitate to ask in case you have any questions.

Best regards,

Tobias Bolch, Editor TC

Dear Maria and co-authors,

Thank you for your carefull revisions.
I can accept the manuscript as is now. However, I sill recommend just to mention the resonse time of glaciers earlier in the manuscript. But I leave this up to you.

Best regards,

Tobias
