we have data, and we have history (in the form of the surrounding area,, dry beds, canyons etc) that tell us how an area was,
then add technology, drill this, dam up that, thinking we can populate an area
so X many millions move into an area that has a known rainfall, of X inches a year, and has been dry since the last ice age, and we blame climate change,,,
just maybe the problem is not the climate that is changing,,,
