As some rural economies in the Southwest are primarily supported by local mining operations, any climate-related changes affecting the efficiency of mining becomes a critical issue. By anticipating these changes, mining interests can prepare and handle whatever climate changes may occur. As climate varies and changes over time, human beings are forced to adapt to resulting changes in their living environments. Warmer temperatures can lead to heat-induced illnesses. Dryer conditions can lead to breathing difficulties, compounded by increases in the amount of dust in some areas.
Urban areas are also susceptible to climate variability.
Electrical storms, floods, extreme heat, and high winds may result in injury or death, property damage or loss, and damage to natural ecosystems. Such threats to human life and health, fresh water supplies, economic activity, public infrastructure, and private property may be countered with appropriate planning. High temperatures increase electricity demand for cooling. If model projections are right, the Southwest could see increases in the frequency and duration of extremely hot summer months. Power plants will have to increase capacity to supply the increased energy demands.
