Her yr Hinsawdd, Series 2

In the second series, Professor Siwan Davies visits California to give a lecture at the world’s biggest event dedicated to her field, and then takes us to see how fires are destroying the state just as Donald Trump comes into power. She visits Uganda to see how tree planting is literally saving lives, and how the wildlife of Costa Rica is in peril. And then there’s the canary in the coal mine – Svalbard – where the permafrost beneath her feet is melting resulting in fatal mudslides, and where climate change effects can be seen first.
