What is the ice budget?

The ice budget refers to the balance between ice accumulation and ice loss within a glacier or ice sheet over a specific period. It encompasses factors such as snowfall, ice melt, sublimation, and calving events. A positive ice budget indicates more accumulation than loss, leading to glacier growth, while a negative budget suggests more loss than accumulation, resulting in retreat. Monitoring the ice budget is crucial for understanding climate change impacts and sea level rise.
