I’ve been thinking about climate change: there have been several articles recently about the areas of Wales that will be lost to rising seas over coming decades. This is going to cause major social and economic upheaval. It’s going to demand that our society direct huge amounts of resources to defending ourselves from the sea – which means that those resources won’t be available for other social programmes that many people depend on. Large numbers of people may be forced to leave their homes and communities for ever. This is inevitably going to be traumatic. This is where we will need our bards. In Wales, the figure of Gwyddno Garanhir tells us that this has happened before, and we survived. If we did it before, we can do it again. Gwyddno connects the tales of Taliesin and of Gwyn ap Nudd: the tales of poetic inspiration, and of deadly challenges.
