For some reason it bothers me a lot that this doesn't acknowledge that this graphic is a remake of two sets of very important USGS historical photos documenting & visualizing land subsidence from groundwater withdrawals in CA's Central Valley.
Yes, the USGS work is public domain, but still.
You may not feel it, but the ground beneath you may be sinking.
In fact, the surface of California’s Central Valley is nearly 30 vertical feet lower than it was a century ago.
Why is this happening? Because our planet is rapidly drying. THREAD/
