Why in news
Analysis of rising surface air temperatures and increased monsoon variability in India due to climate-induced moisture capacity changes.
Background
India's surface air temperature rose by 0.7°C between 1901 and 2018. Climate change is intensifying monsoon patterns by increasing atmospheric moisture capacity and causing shorter dry spells followed by intense rainfall bursts.
Facts for Prelims
- FactIndia's surface air temperature rose by 0.7°C during the period 1901-2018.
- S&TClimate change increases atmospheric moisture capacity, leading to more intense storm systems.
- EnvironmentMonsoon variability in India is characterized by shorter dry spells and intense rainfall bursts.
For Mains
Q. Discuss how climate-induced changes in monsoon patterns necessitate a shift from traditional disaster management to climate-resilient urban infrastructure planning in India.
Dimensions to cover in your answer
- Infrastructure mismatch: Existing urban drainage systems are inadequate for high-intensity, short-duration rainfall bursts.
- Adaptation gap: Need for localized climate-resilient building codes to mitigate flood risks in high-vulnerability zones.
- Data-driven planning: Requirement for high-resolution meteorological modeling to inform municipal spatial planning.
