So this was maybe nine months after the fire in Notre Dame, and I had been struck visually by the fire, the yellow smoke, which is a telltale indicator of lead. The fact that 400 tons of lead constituted the covering of the roof of the cathedral. And a lot of that had volatilized, presumably, but no one really knew how much. So that got me thinking, and I happened to be in Paris at the time, so I thought if it's so much lead, could it be that it affected the population living within say a kilometer of the cathedral? I thought there wasn't really a lot of clear information about what had happened, and what had been measured. I thought some more openness and transparency was needed.

A lot of people think climate change is about avoiding the extinction of mankind. In my opinion, climate change is about putting pressure on society and disrupting society to an extent that it can't function properly anymore. So my greatest fear is that if we don't combat climate change, the weather extremes will hit us with a frequency and intensity that we will not be able to recover after each impact. And then we will start to fight with each other.
