While we know that the global climate is changing, one burning question is how much of this change is due to solar activity. We speak with science journalist and author Stuart Clark about how solar weather affects the earth’s climate, and how the sun’s strange new behaviour over the last few years might allow us to determine its role in climate change.

Producer Daryn Caister speaks with Stephanie Iris Weiss, the author of the book “Eco-Sex: Go Green Between the Sheets and Make Your Love Life Sustainable” to find out how your love life affects the environment and how romance can help save the planet… if you’re doing it right.
