The report Our Changing Climate shows that summer 2025 was the warmest ever recorded in Ireland, driven in part by rising night-time temperatures.

The CCAC report examines how climate change is becoming more visible in Ireland through rising seasonal temperatures and changing weather patterns. By highlighting record summer heat and the role of warmer nights, it points to growing challenges for public health, ecosystems, and essential services, while stressing the need for stronger adaptation and mitigation measures.
