We usually see young people as the face of climate activism. This week, we find out how 2,000 Swiss women, all over the age of 65, took their government to court in a case that could change climate laws across Europe. And along the way, we figure out once and for all how the European Court of Human Rights actually works.

Katy's never voted in a European election before. This week she tries to make amends by figuring out, finally, what the European parliament is and what MEPs actually do.
