Our changing climate in 2025

This report provides an overview of how the climate is changing globally and in specific contexts (like Ireland), combining recent scientific evidence, observed trends, and projections. It examines temperature increases, changing rainfall patterns, and the growing frequency and intensity of extreme weather events, linking these changes to human-induced greenhouse gas emissions. It also reviews notable climate events in 2025, such as wildfires, hurricanes, and droughts, and assesses their impacts on sectors like infrastructure, ecosystems, and the economy, emphasizing the increasing need for climate services, monitoring systems, and resilience planning.

The report finds that most extreme weather events in 2025 were significantly influenced by human-driven climate change, with severe disasters causing major economic losses (over €100 billion) and widespread social impacts. It highlights clear trends such as rising temperatures, more intense storms, prolonged droughts, and increasing pressure on infrastructure and natural systems. The findings stress that without stronger adaptation, improved data systems, and coordinated responses, climate risks will continue to escalate across sectors and regions.
