Groundwater depletion in California’s Central Valley accelerates during megadrought - Nature Communications

Liu et al. used the NASA GRACE/FO missions to show that since 2019, groundwater depletion in California’s Central Valley has accelerated by 31% compared to recent droughts, and has increased by a nearly a factor of 5 compared to the 60-year average.

Here then is the #challenge of #nature to man -- #movewater to replenish the dwindling #groundwater. Creatively use the #solarenergy to #reversetransfer of #seawater to the land.

@ogb @petergleick I don't believe this is possible at the scale required. A rough calculation would indicate an area equivalent to at least 1/4 the size of the aquifer would need to be covered in solar panels.

I am trying to #imagine your #design to #movewater from the #PacificOcean to and through #California, and the positioning of the #solarpanels
