Climate Change in Arizona
The change in annual average temperature compared to the 1970 baseline. Positive values indicate warming.
The percentage change in annual precipitation (rain + snow). Negative values indicate drier conditions, positive values indicate wetter conditions.
Notable changes in extreme weather patterns including heat waves, storms, droughts, floods, and wildfires compared to historical averages from the 1970s.
The most significant climate-related threat facing this region, based on current trends and projections from climate scientists.

Energy Saving Tips for Arizona
Practical ways to reduce your energy usage and carbon footprint.
Upgrade to a Smart Thermostat
Smart thermostats learn your schedule and preferences, automatically adjusting temperature settings to reduce energy waste. They can be controlled remotely via smartphone apps, allowing you to make adjustments even when you're away from home.
Switch to LED Light Bulbs
LED bulbs use up to 90% less energy than incandescent bulbs and last 15-25 times longer. Replace your most-used lights first for maximum impact. Look for ENERGY STAR certified products.
Seal Air Leaks Around Windows and Doors
Air leaks can account for 25-30% of heating and cooling energy use. Use weatherstripping and caulk to seal gaps around windows, doors, and other openings. Check for drafts on windy days.
Use ENERGY STAR Appliances
When replacing appliances, choose ENERGY STAR certified models. These appliances meet strict energy efficiency guidelines and can significantly reduce your electricity consumption over time.
Install Low-Flow Showerheads
Low-flow showerheads use 2.0 GPM or less compared to standard 2.5 GPM heads. This reduces both water use and the energy needed to heat that water. Look for WaterSense labeled products.
Consider Solar Panel Installation
Solar panels can significantly reduce or eliminate your electricity bills. With federal tax credits and many state incentives available, the return on investment has never been better. Get quotes from multiple installers.
Drive Electric or Hybrid
Electric vehicles produce zero direct emissions and are 3-4 times more efficient than gasoline cars. With growing charging infrastructure and federal tax credits up to $7,500, EVs are more accessible than ever.
Adjust Your Water Heater Temperature
Lowering your water heater temperature to 120°F can reduce energy consumption by 3-5% for every 10 degrees. This also reduces the risk of scalding and extends the life of your water heater.
Use Power Strips for Electronics
Many electronics draw power even when turned off (phantom loads). Use smart power strips that cut power to devices when not in use. Unplug chargers when not actively charging devices.
Add Attic Insulation
Proper attic insulation prevents heat loss in winter and heat gain in summer. The recommended R-value varies by climate zone. Consider adding insulation if yours is below the recommended level.
Plant Shade Trees
Strategically planted trees can reduce air conditioning needs by 25%. Deciduous trees on the south and west sides provide summer shade while allowing winter sun. Trees also absorb CO2.
Use Ceiling Fans Efficiently
Ceiling fans use much less energy than air conditioners. In summer, run fans counterclockwise to create a cooling breeze. In winter, run clockwise at low speed to circulate warm air from the ceiling.
