Mutual effects of ablation and ice temperature in a firn-free glacier: Observations from Aug 1st glacier on northeast Tibetan plateau.

Observations show that for glaciers with firn layers, englacial temperature exhibits an increasing trend. 10 , 20 Notably, the direct contributions and range of influence of atmospheric sensible heat and solar radiation on englacial temperature increase are limited. 26 Instead, meltwater infiltration and refreezing have been identified as the primary drivers of englacial temperature increase in such glaciers. 9 Once the infiltration depth of meltwater exceeds the infiltration depth of winter cold air, glaciers undergo abrupt and irreversible changes in their properties. 8 , 26 Changes in englacial temperature reflect the cumulative effects of long-term climate change.
