@ajsadauskas @jaystephens Ta, interesting. I vaguely recall some of that, but your helpful toot defo provided more info than i knew.
I think something like this is why i feel, & tbh remain, so archly cynical... If Straya, & frankly the rest of the world, was genuinely honestly doing all the serious shit needed NOW to decarbonise & ameliorate, then seeking engineering solutions in flood zones like this would be ok. Knowing though that we & most others are totes NOT seriously addressing the crisis, fuels [boom tish] my severe pessimism, coz eg, engineering designs need engineering assumptions [in this case including expected heights & frequency of floods]. Such assumptions necessarily must be predicated on a certain "steady state" belief [plus safety margins thrown in]. That's all fine, IF we had reason to trust such assumptions. I do NOT trust them, simply coz there IS no steady state; humans are continuing to add more & more CO2 & CH4 to Gaia's atmosphere, thus more & more raising the enthalpy, ergo the heating energy, ergo... yada yada.
