As a result of our interest in and the importance of green down data and its relationship to climate change, we decided to analyze data throughout Ohio to really understand if the leaves were changing color and falling sooner than they have in the past thirty years. We used the GLOBE plant color guide to observe eight different trees every week. Using a combination of our personal observations and data from the past thirty years across Ohio, we observed that the leaves have been falling sooner than they have for the past few years, likely as a result of climate change.
