Working with a Changing Climate A guide to adaptation in the Clwydian Range and Dee Valley AONB What the Clwydian Range and Dee Valley does for us This special landscape: • Is a home for people and various species of flora and fauna • Supports the economy, including farming and tourism • Provides food, fuel and materials from its fields, forests and quarries • Provides local water supplies and helps to manage flood risk • Helps to regulate the local climate and provide a clean, healthy atmosphere • Contributes to a strong sense of place for local communities and visitors • Provides opportunities for leisure, recreation, exercise, enjoyment, health and wellbeing for all • Is a physical record of our cultural heritage Clwydian Range and Dee Valley Working with a Changing Climate 3 Introduction The natural beauty of the Clwydian Range and Dee The designation of the Clwydian Range and Dee Valley as an Valley AONB must be conserved and enhanced, but AONB means that its natural beauty must be conserved and it is also a living and working landscape which is enhanced. It is, however, also a living and working landscape continuing to change over time. Climate change is which provides vital resources and services within the AONB and to the surrounding area. having an increasing influence on the area and we need to take action to adapt. This guide aims to help The Clwydian Range and Dee Valley has evolved over time, those working and living in the area to do just that. shaped by geological forces, climate and human activity, and this evolution is ongoing. Cimate change is expected to have a major Setting the scene influence in the coming decades, and we need to manage this process, taking action to adapt to the impacts and make the best of the opportunities. The Clwydian Range and Dee Valley Area of Outstanding Natural Beauty (AONB) is the dramatic upland frontier of north Wales, embracing some of the UK’s most wonderful countryside. Purpose of this guide The Clwydian Range is an unmistakeable chain of purple heather- This guide has been designed to help those working and living clad summits, topped by Britain’s most strikingly situated hillforts. in and around the AONB to understand the potential effects of a changing climate and take action to adapt. It is not a statement of Beyond the windswept Horseshoe Pass, over Llantysilio mountain, policy, but sets out a range of issues and options for discussion lies the glorious Dee Valley with historic Llangollen, a famous and consideration. market town rich in cultural and industrial heritage. It is aimed primarily at a professional audience, but it is hoped Offa’s Dyke Path traverses this specially protected area, one of that the information provided will also be interesting and useful for the least discovered yet most welcoming and easiest to explore of other residents, local businesses and community groups.

Sea-levels are also rising by around 3mm per year. drier summers, warmer wetter winters, more extreme weather and sea-level rise in Wales and Numerous records have been broken for extreme weather in the rest of Britain. recent years. The UK’s wettest summer in 100 years and wettest autumn since records began were in 2012 and the highest temperatures ever recorded were during the 2003 heatwave. In December 2013, the highest storm surge in sixty years caused Historic climate flooding along the North Wales coast.

Although the climate in Wales and the rest of the world has been relatively stable for the last 10,000 years, Recent changes in the global climate have been linked to increasing there have been periods of extreme change in the past. atmospheric concentrations of greenhouse gases such as carbon dioxide. This is largely due to human activity, such as burning fossil 350 million years ago, warm tropical seas covered the land, fuels, deforestation, peatland drainage and some farming practices. depositing the limestone found in the Clwydian Range and Dee Valley. 100 million years later, Wales had a desert climate, while the Global climate change is is projected to continue, causing hotter, valleys of the AONB were carved out by glacial movement during a drier summers, warmer, wetter winters, more extreme weather, series of ice ages, the most recent of which ended around14,000 drought, heatwaves, heavier rainfall, and accelerating sea-level rise years ago. in Wales and the rest of Britain over coming decades.
