Q2. “The twenty-first century marks a transition from glacier retreat to glacier extinction as a dominant cryospheric process”. Explain this transition. Analyse the physical drivers behind it, and its long-term geographical consequences. (15 M)
Difficulty Level: Medium

Why the question Accelerated global warming has transformed glacier change from a process of gradual retreat into one of large-scale extinction, making it a critical issue in contemporary physical geography and climate studies. Key Demand of the question The question demands an explanation of the transition from glacier retreat to glacier extinction, an analysis of the physical drivers causing this shift, and an examination of its long-term geographical consequences. Structure of the Answer: Introduction Briefly introduce the twenty-first century as a decisive phase in cryospheric change, where glacier dynamics are increasingly characterised by irreversible loss rather than mere shrinkage. Body Explain how glacier change has shifted from gradual retreat to complete extinction of glaciers. Analyse the major physical drivers such as sustained warming and glacier response characteristics behind this transition. Examine the long-term geographical consequences for hydrology, geomorphology and mountain landscapes. Conclusion Conclude by emphasising the permanence of glacier extinction and its significance for future geographical and environmental processes.
