Match the international agreements and atmospheric phenomena related to climate change and ozone layer depletion in List-I with their primary descriptions or objectives in List-II:
- Kigali AmendmentLegally binding phase-down of high Global Warming Potential (GWP) Hydrofluorocarbons (HFCs)
- Kyoto ProtocolInternational agreement committing industrialized nations to limit and reduce greenhouse gas emissions
- Stratospheric OzoneAtmospheric shield that absorbs biologically harmful solar Ultraviolet-B (UV-B) radiation
- Tropospheric OzoneSecondary air pollutant and short-lived climate pollutant formed via photochemical reactions
Answer
The correct matches are: Kigali Amendment pairs with the legally binding phase-down of high GWP HFCs; Kyoto Protocol pairs with international commitments to limit greenhouse gas emissions; Stratospheric Ozone pairs with the atmospheric shield absorbing harmful UV-B radiation; and Tropospheric Ozone pairs with the secondary air pollutant formed via photochemical reactions.
The Kigali Amendment explicitly targets the phase-down of Hydrofluorocarbons (HFCs) due to their high climate-warming impact. The Kyoto Protocol establishes binding emission targets for major greenhouse gases. Stratospheric ozone functions as a protective shield against ultraviolet-B radiation, whereas tropospheric ozone operates as a secondary air pollutant and short-lived climate force.
