Climate change, its impact on Arizona, and our responsibility

April 25, 2023

Climate change is a long-term shift in weather patterns and temperatures. These shifts are caused by natural phenomenon like variations in solar cycles and/or human activities like production of greenhouse gases. Since the 1800s, human activities—primarily the use of fossil fuels—have become the main driver of climate change. Burning of fossil fuels like coal, oil and gas generate greenhouse gases, such as carbon dioxide and methane. These gases act like a blanket wrapped around the earth that traps the sun’s heat and results in rise of the temperatures on earth. 


Climate change in Arizona and the southwest region has contributed to increased heat, drought, and water shortages. Adverse challenges include increases in the numbers and severity of wildfires,  heat-related health illnesses and deaths, declining the water supplies, poor air and water quality, and reduced agricultural yields.

What are some things you can do today to help mitigate the climate crisis? 

  • Use less energy  or switch to renewable energy at home
  • Walk, bike, or use public transportation 
  • Eat more vegetables
  • Throw away less food
  • Reduce, reuse, repair, recycle
  • Switch to hybrid or electric vehicles
  • Learn more about climate trends and their impacts where you live to identify ways you can stay safe and healthy, especially during the hot summertime months
