How do we maintain communications in the face of climate calamity events? https://www.rnz.co.nz/programmes/the-detail/story/2018881865/preventing-a-communications-blackout-in-the-next-big-disaster One approach is to regulate the telcos to mandate that cellphones can talk to one another directly, without going via a celltower. Telcos don't want to do that (because they can't track & clip the ticket on all communication), but it's possible: there've been #FOSS projects to do so for years, including the ServalProject - http://servalproject.org/ - which was initiated after the Haiti earthquake.
