I vaccilate between being very confident about climate change and not at all confident.

I look at the cost trajectory of renewables and the increasing pace of rollout and I think - we've just about got this. Renewables are going to be cheap enough, soon enough that we'll avoid most of climate change. And then some days I look at it and I think, we've missed this by 20 years.

But we are definately moving and whilst we can't have it all *now* every solar panel or wind turbine installed today is a little bit of carbon avoided
