Q2. What makes the Antarctic stratosphere uniquely prone to severe ozone depletion? Analyse how global warming may alter these conditions. Discuss the potential shifts in future ozone-hole patterns. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question The 2025 Antarctic ozone hole closed unusually early, raising analytical relevance about Antarctic atmospheric vulnerability, climate–stratosphere interactions and future ozone-hole behaviour. Key demand of the question The question requires explaining why Antarctica experiences extreme ozone depletion, analysing how global warming alters these stratospheric conditions, and discussing the likely shifts in future ozone-hole patterns. Structure of the Answer: Introduction Briefly introduce Antarctica as the coldest, most isolated stratospheric region where unique chemical and dynamical conditions intensify ozone loss. Body Unique Antarctic vulnerability: Highlight one core atmospheric–chemical condition that makes the Antarctic stratosphere prone to severe depletion. Impact of global warming: Highlight one major warming-driven alteration in stratospheric temperature or circulation influencing ozone behaviour. Future ozone-hole patterns: Highlight one broad expected shift in timing, size or variability of ozone holes under evolving climate conditions. Conclusion Give a short forward-looking statement on integrating ozone monitoring with climate modelling for anticipating long-term atmospheric risks.
