A third part of the work involves carbon capture and geological injection underground, into rock formations where it can be stored safely for millennia.

if there is one element that recurs and stands out for cities, it is the making and using of vertical options.

Planet City is built entirely from sustainable technologies that are already here, but that just lack the cultural investment or political will to implement them at scale.

The future is broken and we are left stranded in the long now, doomscrolling idly, waiting out the end of the end of the world.

Planet City may be more generative if we consider it to be a temporary destination. What if it was a place to retreat to while giving time for carbon removal and regeneration, while actively restoring the climate?

We are all already living in a planetary city, a distributed mega structure hiding in plain sight.

Managed retreat is ‘the strategic relocation of structures or abandonment of land to manage natural hazard risk’.

to address climate change, an active restoration is needed.

the path towards Planet City runs through political revolution. The paradox of Planet City is that at the current rate of social change, by the time the need for Planet City has fully dawned, the political and financial capacity to build it may be too far eroded to realise it.
