National Climate Change Risk Assessment Main Report
Summary: Ireland’s first National Climate Change Risk Assessment (NCCRA) provides a comprehensive national overview of the potential risks and opportunities posed by climate change for Ireland. It will play a critical role in meeting national policy objectives and supporting sectoral and local authority climate adaptation planning processes. The NCCRA integrates scientific and technical knowledge with input from expert stakeholders, to identify, assess, and prioritise climate change risks to build a comprehensive understanding of risks.
The NCCRA identifies a total of 115 risks for Ireland across the nine systems assessed. 43 of these risks were then deemed to be significant in terms of impact at a national level. These were then then investigated the effectiveness of completed, ongoing and planned adaptation activities in addressing these risks.
A total of nine risks were identified as priority risks, four of which were classified as requiring urgent action within the next five years to offset substantial impacts in the short term and potentially critical impacts in the long term.
Over the coming decades, the proportion of the 43 significant risks that move in consequence rating from limited to substantial to critical and to catastrophic increases. Risks in a system also have the potential to cascade and impact upon other systems. The NCCRA identified the cascading impacts across systems, with the Biodiversity and Ecosystem, Economy and Finance, Health, and Social systems being particularly impacted by risks from other systems.
The NCCRA also identifies potential transboundary impacts for Ireland related to food security, supply chains, economic stability, and human mobility that may result from impacts of climate change that occur outside the state
