About Singapore's Third National Climate Change Study (V3)

Climate change is an existential threat for humans and other beings on Earth. With increasing evidence of the risks associated with climate change, countries globally especially small island nations like Singapore need reliable and actionable climate change information to be prepared well in advance to adapt to the multi-faceted risks due to climate change.

The latest Inter-governmental Panel on Climate Change (IPCC) 6th Assessment Report is based on scientific literature that primarily comes from the analysis of climate change projections of global climate models. While the information is useful to inform global and large-scale climate change, they lack the granularity to assess climate change at the regional and local levels. As a follow up on Singapore’s Second National Climate Change Study (V2) released in 2015, Singapore’s Third National Climate Change Study (V3) provides the required high-resolution climate change projections for Singapore and the wider Southeast Asia region, by dynamically downscaling the coarse resolution global climate model simulations. This new data set can be readily used for adaptation planning and thus help safeguard Singapore from the adverse effects of climate change.

V3 is undertaken the Centre for Climate Research Singapore (CCRS) under the Meteorological Service Singapore (MSS). The Study represents a significant advancement in climate change science for Singapore and the Southeast Asia region.

Key Features of V3:

  • V3 provides the world’s highest-resolution (8km) climate projections for Southeast Asia, based on the latest insights from the IPCC AR6.
  • V3 presents future climate scenarios for Singapore and the region using IPCC’s Shared Socioeconomic Pathways (SSPs), envisioning diverse outcomes based on three different greenhouse gas emissions and socioeconomic storylines.
  • V3's dynamical downscaling process offers detailed insights by transforming Global Climate Model (GCM) information into localised climate conditions using CCRS’s in-house Regional Climate Model (RCM).

Supporting Climate Resilience in Southeast Asia

Southeast Asia is a region of the world that is most vulnerable to the impacts of climate change. It is therefore crucial for countries in the region to have access to higher resolution climate change projections to support the formulation of national climate adaptation plans. As host to the ASEAN Specialised Meteological Centre (ASMC), MSS is making available the data and findings of V3 to ASEAN member states. This is in line with one of ASMC’s roles in supporting the scientific understanding and prediction of climate change and its impacts within the Southeast Asia region.

About the V3 Data Visualisation Portal

The V3 Data Visualisation Portal aims to make the findings of V3 accessible and actionable, empowering stakeholders in Singapore and the Southeast Asia region to address the local impacts of climate change effectively.
