And am I correct that these dunkelflautes are becoming an increasing concern because of the increased likelihood of extreme weather events? Otherwise I don't really see why this is suddenly a bigger concern now, than it was, say, 50 years ago...?

Forgive me for being sceptical, but you did state that batteries have solved base load for most of the planet. Australia is probably the least convincing example anyone could pick, due to its extremely low population density, long coastline, and high amount of sun hours. I'd be much more interested in seeing this calculation for places like China, India, Nigeria, Brazil, Russia.

Most of the world's population lives equally or nearer to the equator than Australia.

Australia has a head start on solar mostly due to low costs of capital letting people invest long term. Same reason Northern Europe deploys more solar than you'd think is globally sensible.
