I don't believe there is a climate emergency.
And that's the problem, right there. We have a huge, global problem, and the leader of our major opposition party refuses to accept that it exists.
National simply isn't serious about climate change. And until they are, until they advocate the sort of emissions reductions we need, and the sort of policies we need to get them, they are unfit for office. If you're wondering what personal action you can take on climate change, here's an obvious one: vote out National, and vote only for parties who will actually do something.
