The Climate Assessment for the Southwest (CLIMAS) is a program by the University of Arizona that aims to study the effects of climate variability and longer-term climate change on human and natural systems in the Southwest United States. The program has already predicted that the southwestern United States will become drier and the transition to a more arid climate is already taking place. Other projections include fewer frost days, warmer temperatures, greater water demand by plants, animals and people, increased frequency of extreme weather events, warmer nights, declines in snow pack, an earlier spring snow melt, which will then reduce water supply, lengthen the dry season, create conditions for drought and insect outbreaks, and increase the frequency and intensity of wildfires.
