| Summary | Our analysis shows that significant increases in lake area were 5.6 times more frequent than decreases during the study period. Wildfire and ground ice abundance were the most important predictors of the direction of change. Greater ground ice content was associated with regions that experienced increases in lake area, while wildfire was associated with regions that experienced decreases in lake area. The effects of climate, including trends in mean annual temperature and total annual precipitation were smaller than disturbance and environmental factors, indicating that climate has likely had indirect effects on lake area changes over our period of study. |
| Local Relevance | Relevant to the Northwest Territories, the study shows that permafrost thaw and wildfire are key drivers of changing water systems, affecting lakes, ecosystems, and water resources in regions like Yellowknife. |
| Notes | This study covers approximately 1.4 million km2 of northwestern Canada, including the Northwest Territories, Yukon and Nunavut. |
