First Minister, it's clear that a growing number of people—our young people and, indeed, the older generation concerned for their grandchildren—do not think that the current scale and pace of action to combat climate change is sufficient. I think we've seen, with Extinction Rebellion and the number of people protesting, the number of arrests and, indeed, Greta Thunberg, as an amazing 16-year-old advocate for our environment, manifestations of that strength of feeling. As you say, there's a worldwide movement now to do more and, I think, to go faster. So, I very much welcome the Welsh Government's declaration of a climate emergency but I do believe it needs to be followed by new energy and new action. One key area, I believe, is transport, and I do think we need a more integrated, a much more integrated, transport system in Wales. One great opportunity is the south Wales metro, and I wonder, First Minister, if Welsh Government will now look at whether it's possible to radically strengthen and accelerate the programme of work for that south Wales metro.
