Cardiff is facing significant risks from climate change, with a particular focus on rising sea levels. Recently, the United Nations Secretary-General, António Guterres, highlighted the urgency of addressing the impact of sea level rises on vulnerable nations, stating, “Rising seas are a crisis entirely of humanity’s making… But if we save the Pacific, we also save ourselves.†This underlines the interconnectedness of global climate challenges.
Research has shown that Cardiff is among the top ten most vulnerable cities worldwide to the effects of climate change. Factors considered include sea level rise, climate shift scores, and water shortage risks projected by 2050. While Cardiff may not face significant drinking water shortages due to its rainy climate, the threat of rising sea levels is substantial. Natural Resources Wales has mapped areas in Cardiff that could be underwater with a 1.1m rise in sea levels, particularly impacting the eastern parts of the city.
The Gwent Levels, in particular, are at high risk due to their geographical nature, making them susceptible to melting ice caps. Despite the seriousness of these projections, it is emphasised that flood defense infrastructure plays a crucial role in mitigating risks. It is essential to invest in protective measures to safeguard vulnerable areas and communities.
Apart from sea level rise, increased rainfall and river flows due to climate change pose additional risks, leading to potential flooding in built-up areas such as in the northern part of the city. The analysis of Cardiff’s climate vulnerabilities underscores the need for proactive planning and action to address these challenges effectively.
While the focus of this analysis has been on Cardiff, it serves as a reminder of the broader climate threats facing communities across Wales. The incorporation of risk assessments into planning applications reflects the importance of considering climate risks in future development projects. By prioritising resilience and adaptation efforts, Wales can better prepare for the impacts of climate change and protect its communities for years to come.
