(2024), we explore the relationship between statistical and machine learning models in the analysis of environmental time series. We specifically address the unique challenges of environmental time series data, including the need to consider the multivariate approach and account for spatial dependence. Emphasizing the importance of various types of statistical inference in environmental studies—not limited to forecasting—we propose that viewing statistical and machine learning approaches as complementary rather than alternative methods can unlock innovative modeling strategies that enhance both predictive accuracy and interpretive power. To illustrate these concepts, we present a case study that highlights the key points raised in the discussion.  \n1 | Introduction  \nWe would like to acknowledge the authors for their significant contribution to the examination of the relationship between statistical and machine learning (ML) models within the context of environmental time series. Their work raises an important question: should traditional statistical methods in environmental analysis be replaced by ML approaches? This question is followed by a comprehensive literature review that reveals a growing interest within the environmental statistics community in exploring the adaptability and potential of flexible ML models. The question is addressed by analyzing two distinct environmental datasets.  \nThe first dataset comprises daily measurements of PM2.5 (fine particulate matter smaller than 2.5 microns) concentrations from 12 air pollution monitoring stations (without any missing data) in  \nthe Golden Horseshoe region of Toronto, Canada. The data spans from January 1, 2009 to December 31, 2019, and allows for the evaluation of both predictive accuracy and uncertainty quantification, as the seasonal and environmental complexities provide a robust testing ground for comparing statistical and machine learning models.  \nThe second dataset consists of hourly meteorological data from a citizen science weather station near South Bend, Indiana, USA. The station records continuous measurements of temperature and wind speed, aggregated to an hourly level from July 20, 2020 to December 31, 2021 . This dataset features clear seasonal patterns, with temperature following typical mid-latitude seasonal variation and wind speed showing increased variance in fall and winter. This dataset provides another opportunity to assess model performance in capturing these dynamics, particularly in time series with shorter temporal resolution.  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2025 The Author(s).
