Multilateral climate frameworks and India disaster vulnerabilities

Source:The Hindu ↗

Why It Matters

Highlights India's vulnerabilities to climate-induced hydro-meteorological disasters and discusses the effectiveness of technology, such as geoengineering, alongside the persistent necessity of a multilateral framework like the Paris Agreement.

Summary

At 'The Hindu Huddle 2025', climate experts emphasized that despite political shifts like the U.S. withdrawal from the Paris Agreement, multilateral climate regimes remain critical. The panel discussed the rapid pace of global warming, which is outpacing predictive models, and highlighted India's extreme vulnerability, noting that 75% of Indian districts are climate hotspots and 80% of the population faces risks from hydro-meteorological disasters. While technological interventions such as geoengineering and enhanced rock weathering (ERW) present potential solutions, experts cautioned against their unintended side-effects and stressed the need for economic alignment, pilot-scale research, and retaining scientific talent within India.

Key Points

  • Multilateral frameworks for climate change action remain indispensable, overriding political disruptions like the U.S. withdrawal from the Paris Agreement.
  • Global warming is accelerating faster than current climate models have anticipated, underscoring the urgent need for India to develop its own climate models.
  • India faces severe climate risk, with three-quarters of its districts designated as hotspots and 80% of its population exposed to hydro-meteorological disasters.
  • Emerging technologies like geoengineering and Enhanced Rock Weathering (ERW) offer promise but require rigorous, long-term pilot studies due to potential side-effects.
  • Effective climate action must integrate economic strategies, framing the transition to clean energy as a national industrial policy.
  • To lead in climate research and modeling, India must prevent the brain drain of its doctoral researchers to the United States.

Important Terms

Paris Agreement

A 2015 international treaty aiming to limit global warming to well below 2°C, preferably 1.5°C, through Nationally Determined Contributions (NDCs).

Prelims Trap

Enhanced Rock Weathering (ERW) involves capturing CO2 directly from industrial smokestacks and injecting it underground.

ERW is a Carbon Dioxide Removal (CDR) technique that spreads crushed silicate rocks on soil to absorb atmospheric CO2, distinct from industrial CCS.

Static Concepts Connected

Environment & Ecology

What is Enhanced Rock Weathering (ERW) and how does it sequester carbon?

  • Mechanism: Spreading finely ground silicate rocks (like basalt) over agricultural land or oceans to accelerate natural geological weathering and absorb CO2.
  • Chemical reaction: Atmospheric CO2 dissolved in rainwater reacts with the crushed rock, converting into stable bicarbonates that eventually wash into oceans for permanent storage.
  • Ecological risks: Large-scale mining and grinding require massive energy, while widespread application could alter local soil chemistry and hydrology unpredictably.
International Relations

What are the rules for withdrawal from the UNFCCC Paris Agreement?

  • Article 28: A party may withdraw at any time after three years from the date the Agreement entered into force for that specific party.
  • Timeline: Withdrawal takes effect one year after the deposit of the formal notification to the UN Depository.
  • Regime survival: The agreement remains legally binding for remaining signatories; multilateral emission targets, climate finance mechanisms, and NDC frameworks continue to operate.

Cross-Topic Patterns

  • Geoengineering risks to the Indian Monsoon

    Geoengineering interventions like solar radiation management could inadvertently alter global precipitation, posing a severe threat to the monsoon cycles that dictate India's agrarian economy.

  • Climate modeling as strategic sovereign tech

    The call for indigenous climate models reflects a shift where hydro-meteorological forecasting is treated as critical national infrastructure, intersecting with space tech (ISRO) and supercomputing missions.

Expect a 2026 Prelims question distinguishing Carbon Dioxide Removal (ERW, ocean fertilization) from Solar Radiation Management techniques.
