Meanwhile, other places are experiencing the exact opposite - wells running dry because the water table is continually dropping.

There is one thing I don't understand about the article. The rise in groundwater level should follow the average increase in sea level. It is not like a big wave would suddenly affect the groundwater level. Assuming houses last for 50 years and during the next 50 years the sealevel can increase by around 50cm, it should be easy to check if buildings near the coast are high enough that they can accept this change in s…

I haven't read the article yet but one thing that makes more complicated in the US is the widespread use of septic tanks. The leach field will flood before the actual surface.

Related, this goes into far more detail: https://baynature.org/article/the-sea-beneath-us/

>Water will leach inside homes, she said, through basement cracks. Toilets may become chronically backed up. Raw sewage may seep through manholes. Brackish water will corrode sewer and water pipes and inundate building foundations. And most hazardous of all, water percolating upward may flow through contaminants buried in the soil, spreading them underground and eventually releasing them into people’s homes.

This describes my experience living in Miami. People are already acclimated to saltwater pouring out of drains during "king tides".

Population control. There is no way that we can fit 9-10 billion people on earth and are still able to be sustainable.

Capitalism and Free Market. On an individual basis, apart from zero-cost sustainable habits, if you are capable, become a master of science, attempting to solve energy, material, carbon and climate issue at a physics level. If you are a craftsman, observe all the day-to-day activities of humans, tinker/hack and attempt to solve the same workflows more sustainably. If you have a solution either through hacks or scienc…

Markets and capitalism are part of the solution, of course, but you absolutely do need policies to direct all that energy, at a high level.

Absent "policies" and enforcement, the cheapest way for a factory to dispose of waste is to dump it in the river. Same thing applies to CO2: dumping it in the atmosphere is cheap right now because the policies to deal with that externality aren't quite there.

An obvious example of a policy that might help would be a carbon tax that makes more carbon-efficient things more economically appealing.

==Here's what will 100% not work -- Activism or Trying to 'Policy' out of your way of Climate Change problems.==

Capitalism and Free Market are solutions today exactly because we have aligned our "policy" to make clean energy more attractive to capitalists. People quickly forget policies like the American Recovery and Reinvestment Act of 2009 [1] which invested $80 billion in clean energy. Tesla might not exist today if the DOE didn't loan them $465 million as part of the Energy Independence and Security Act of 2007 [2].

Yes, Capitalism will surely solve the problem that Capitalism wrought, and using tools like Regulation and Policy is sure to hamper Capitalism and not help consumers or the environment at all!

How sad it is that the comment suggesting we try to not continue overpopulating the globe is downvoted while this propaganda piece isn't.

Capitalism and the free market have already been in use and the single cause of the all environmental problems.
