Thank you for your responses to the comments posted as interactive discussion. Please carry out all revisions you intend to do. Particularly, as indicated, you should be more specific about the different aspects of your study. I am looking forward to receiving a revised manuscript, which, I believe, will be a valuable contribution to the literature addressing effects of warming on soil properties.

Thank you for carefully revising the manuscript. I would like you to consider same small changes to the text in the abstract and the conclusions to be more precise about the specificity of your study.
Abstract
- 'However, specific ecosystem responses to warming are understudied'. maybe better: specific soil responses to warming under different ecosystems are understudied

- 'We used a natural geothermal soil warming gradient in an Icelandic spruce forest (0-17.5 °C warming intensity)' should be: We used a natural geothermal soil warming greadient (0-17.5 °C warming intensity) in an Icelandic spruce forest on Andosol

Conclusion:
- 'Using a strong geothermal warming gradient, we highlighted the critical role of SOC for soil structure.' Should be: Using a strong geothermal warming gradient we investigated soil structural changes and their effect on different SOC pools.

-'changes in the soil abiotic environment '- may be better: changes in the microbial habitat and possibly abiotic soil properties

Thank you for the detailed revisions, the manuscript is now ready for publication. Thanks again for choosing SOIL.

Kind regards,
