An Overview of the Impacts of Climate Change on Vineyard Ecosystems in Niagara, Canada
Round 1
Reviewer 1 Report
I have read the manuscript with great interest and I believe that it will be of interest to other readers of the journal. The manuscript reviews the current bioclimatic situation influencing vineyards in Canada, Niagara region. The authors provided a compact but comprehensive review of the literature on various aspects of the impact of climate change on the wine industry in the region. In addition, they provided an overview of agrotechnical measures and management solutions that will help mitigate the negative effects of climate change.
Perhaps, the positive (just my suggestion) effect of the reduced summer precipitation on the grape in terms of fungal diseases should also be mentioned in this article.
Also, I propose minor corrections (find in attached table please)

Reviewer 3 Report
The article presents an interesting comprehensive overview of changes in climate elements that are important for the vineyards of the Niagara Region of Ontario, Canada. Model forecasts up to 2080 of trends in temperature, seasonal precipitation, frequency of extreme events, duration of the frost-free period, and wind strength are analyzed. There are discussed the consequences of meteorological factors changes for vine, soils, pests, pathogens. The work is of practical importance, since measures to adapt vineyard management are also being discussed. There are several suggestions for clarifying the text. The main thing is the poorly structured schemes in Figs. Fig. 1 - The diagram looks disordered. It would be logical to depict phenomena of the same plan at one level, for example: the lower level - extreme consequences, the second from below - the dynamics of temperatures and precipitation in each season, even higher - the names of the seasons, even higher - the elements of climate change. Fig. 2. Not very clear conceptual model. By what principle are Soil organisms and Invertebrates distinguished? Are Invertebrates only in the air? Soil organisms are not divided into useful and harmful? Why do viruses not infect cover cultures? Mineralization and Vine look strange next to each other. The Virus rectangle is not in the same column with Pests and Benefits – by chance or is there some sense in this? Perhaps it would be clearer if you structured the scheme, for example: highlight the levels of soil (below), plants, air.Lines 35-37: ‘Vineyards, either for grape or wine production, are heavily managed perennial agroecosystems of high economic importance, with an estimated wine production of 262 million hL worldwide’ – wine production does not apply to table grapes. Perhaps this sentence should be divided into two.
Line 78: ‘2oC’ – replace ‘o’ with a degree sign.
Lines 80-82: ‘winters are cold, snowy, and windy, while springs and falls are characterized by cloudiness, rainfall, and cooler temperatures' – it turns out that in spring and autumn it is cooler than in winter. Line 151: ‘4. Conecting Climate Change to…’ – conNecting? Line 155: ‘and their interactions: soil, vines, invertebrates, invertebrates, and pathogens’ – ‘invertebrates’ is duplicated Lines 215-216: ‘to advance bud break by 45 days, flowering by 19 days, and veraison by 37 days in temperate areas. Fluctuating’ – it would be better to clarify from which year to which such significant shifts of the dates are expectedAuthor Response

Round 2
Reviewer 2 Report
Since the purpose of the review is not to outline the management practices or provide insight on how to improve them. And by considering other corrections in the revised version, the manuscript in its current state is sufficiently improved for publication.
Best wishes,
