What if we turned Death Valley into a massive reservoir, a lake to modify the weather and landscape? Could it work, or would there be unintended consequences?
Flooding in Death Valley, August 2022 |
What makes something a "desert" is not high temperatures. It is the temperature extremes -- dipping too cold and climbing too hot -- and the inability of the soil to retain water. It runs off, eroding topsoil with it. So it is not the lack of rain that makes for desertification but rather the series of events that follow: loss of topsoil, loss of plants, loss of roots that retain the soil, loss of moisture, temperature extremes, gravel, sand, over mineralization, rocks, floods, and so on.
