Ten years ago today, May 24th 2015, the Pope weighs in to the climate debate
Laudato si’ (24 May 2015) | Francis

The amount of carbon dioxide in the air was roughly 401ppm. As of 2025 it is 430ppm, but check here for daily measures.
The context was that Jorge Mario Bergoglio had been Pope since March 2013. The Paris COP, the latest “last chance to save the world” conference was coming up in November.
What I think we can learn from this is that everyone knew, was warned. And here we are.
What happened next. The Pope kept banging on about it, right up to his end. The new Pope will probably do the same. There is, however, such a thing as “too late.”
What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs.
