It feels like an apocalypse in the southwest — wildfires, floods, drought, heat, smoke. This was not the norm when I moved to Colorado 35 years ago. Climate scientists may have predicted the arrival of these extreme events, but many admit their predictions have come true faster than they expected.

One outcome they pinpointed was the impact of heat and drought on water flows in the Colorado River. For the last 20 years, this new climate, combined with booming human population growth, has parched landscapes, drained reservoirs and incited talk of water wars across the region. Lake Powell on the Colorado River and Glen Canyon Dam, which creates the reservoir, have become casualties of this strained environment.
