Yes. Thank you. His book Aurora does a much better job at steering us towards action while still showing consequences of environmental disaster and I highly recommend it.
One of the coolest things about plantuml is the generated PNG actually contains the source code for the image as metadata. If someone gives you an image, they don't also need to send you the source because you can extract it using the plantuml CLI.
It's not a brave face. The science tells us that we're on a better and improving track. It's not without hope. A decade ago we thought we were on track for 6C by the end of the century.
That said, it's still going to be worse than we all want it to be. Like many things, the truth lies in the middle and all we can do is push hard on the margins.
