Comment les Parties de la CCNUCC, peuvent-elles agir sur les effets climatiques non carbone des forêts

This briefing by the World Resources Institute explains how forests influence the climate through non-carbon biophysical processes and argues that the UNFCCC should integrate these effects into its policies, reporting, and financing to better support climate mitigation and adaptation.

• Forests impact climate stability through four primary non-carbon biophysical processes: albedo (the reflection of solar energy), evapotranspiration (the release of moisture which cools the surface and air), surface roughness (which affects wind speed and turbulence), and aerosols (fine particles and chemical components that interact with the atmosphere).
• Deforestation disrupts biophysical processes with varying impacts based on latitude; in tropical regions, deforestation contributes 50% more to global warming than carbon emissions alone.
• The loss of forests has significant regional and local consequences, including the disruption of rainfall patterns across national borders and sharp increases in local temperatures. For example, deforestation in the Brazilian Amazon affects precipitation in Argentina, Bolivia, Paraguay, and Uruguay. Locally, while average greenhouse warming may be 1°C, some communities have experienced increases of 7.6°C during peak hours due to the loss of forest cooling.
• The document argues that the UNFCCC can integrate non-carbon forest effects into existing frameworks, noting that the Paris Agreement already defines the climate system as the interaction of the atmosphere, hydrosphere, and geosphere, and Article 5 specifically mentions "non-carbon benefits."
• The authors propose six specific actions for UNFCCC Parties to address biophysical forest effects: expanding annual GHG inventory reports, including biophysical effects in Nationally Determined Contributions (NDCs), integrating these benefits into REDD+ reporting and finance, incorporating them into national adaptation plans and funding requests, including them in the Global Stocktake, and ensuring their inclusion in the IPCC's Seventh Assessment Report (AR7).
