Climate Change in the Irish Mind Wave 2 Insight Report Number 3 Climate Literacy
How does knowing that humans are the main cause of climate change affect your climate literacy, perspective on climate change, support for climate policies?, December 2025
Year: 2025
The ‘Climate Change in the Irish Mind’ project (CCIM) is a nationally representative study of the Irish people’s beliefs, attitudes, policy preferences and behaviours regarding climate change, undertaken by the EPA and the Yale Program on Climate Change Communication. The CCIM Insight report “Climate Literacy” investigates how the public’s understanding of human caused climate-change connects to their overall climate knowledge, their support for climate policies, and their views on climate change.

Research 503: The Irish Hydrometric Reference Network Version 2.0
Authors: Paul O’Connor, Conor Murphy and Niamh Cahill, December 2025
Year: 2025
Hydrometric reference networks are crucial for tracking climate variability, hydrological modelling and extreme events. This research, led by a team in Maynooth University, enhanced the Irish Hydrometric Reference Network (IHRN) to better detect climate-driven changes in river flows across Ireland. Building on the EPA HydroDetect project, it adds a key tool for water management and addresses gaps in understanding floods, average flows and droughts. Findings show increasing high and mean flows in winter and decreasing low flows in spring and summer indicating greater flood and drought risks. Long-term reconstructions show stronger seasonal trends and the influence of the North Atlantic Oscillation. The updated IHRN dataset underscores the importance of hydrological modelling, flood risk management and climate resilience planning. The research recommends expanding the network to include groundwater and lakes with coordinated national oversight to ensure Ireland’s hydrological resilience.
