Mass

rising tides flood the tunnels too late
the higher ground
ocean levels glaciers melt
the ice sheets form long-term
disappearing latitudes
recessions change the map
far below freezing surface temperature
lost supply
routinely under global change
sinking is accumulative
build it higher
shutdown flooding storms
the ice caps the big one
the human time scale
demolition plan
before and after black and white
history shows in this hour
last call
too far along to prevent
slowed but not quite stopped
