Carbonic's on their "force majeure" shit again:

Carbonic Service will declare force majeure due to feed gas supply issues affecting our CO2 supplier [...] We have no estimated end date, but we will continue to monitor the situation closely. [...] In the meantime, we have sourced CO2 from an out-of-state provider at a significantly higher cost [...which we will pass on to you].

Last year:

Now I'm just an unfrozen caveman, your modern climate confuses and frightens me; when I went into the ice, atmospheric CO2 was at 175ppm.

But apparently now there's a CO2 shortage?

Previously, previously, previously, previously, previously, previously.
