The study found that the movement of the Greenland ice sheet is minimally affected by late melting

Extreme melting and precipitation events can accelerate ice flow on the Greenland Ice Sheet, potentially causing more ice to move to lower elevations, where temperatures are warmer and melting rates are higher. Several unprecedented melting events occurred in September 2022. Their intensity caused some glaciers on the ice sheet to accelerate by 240 % compared to their pre-event speeds. Despite these accelerations, our analyses show that these events had only a minimal long-term impact on how much ice moved to lower elevations due to the short duration of the accelerations. As a result, while these melt-induced accelerations are expected to be more common in warmer climates, their impact on the amount of ice transported toward the ice sheet's edges is minimal. (Ryan N.
