Nothing quite as HN as someone making bold alarmist unsupported assertions about the future of climate for all of time, then following it up with a sentence demanding an appreciation for “basic facts”.
- ClumsyPilot 3y agoAre you at odds with basic addition or something? We are pumping out the aquifers faster than they recharge. Basic math lets you calculate that they will run out in a few decades. The aquifers are left over from the ice age. Once depleted, the aquifer will take over 6,000 years to replenish naturally through rainfall.
- explaininjs 3y agoSo we now agree the aquifers have the capacity to refill on human timescales, especially given climate change is suspected to have a tendency to cause more rainfall. And by your omission I’ll take that we agree civilization cannot exist without significant engineering efforts to bring water to it, surface or otherwise. I don’t really know what’s left to say, besides hurling personal attacks back and forth as you seem want to steer this.
