What would the effects on climate in western United States be if Death Valley were an inland sea connected to Gulf of Cortez?

The effects of an inland sea in Death Valley connected to the Gulf of Cortez on the climate of the western United States would be dramatic. The presence of a large body of water would raise humidity levels and increase precipitation, leading to decreased evaporation and drought. As a result, the region would experience more moderate temperatures, with hotter summers and milder winters. The influx of moisture would also change vegetation patterns, promoting growth in both desert and coastal ecosystems. Additionally, the increased water availability would provide opportunities for additional agriculture and recreation in the region.
