I saw a study recently that estimated that some significant percent of sea level rise- maybe 10%-comes from groundwater extraction.
I'm not a hydrologist but I guess it makes sense- if you're pulling more groundwater than is recharged the hydrological cycle takes it somewhere.
That's a really big deal in China and India. And maybe a reason why business may be good for those who own land in moderate climates with adequate rainfall and soil water holding capacity.
Probably also true of climate change- perhaps the deniers here actually have some self interest, although that would be fairly pathological.
