How Climate Change is Impacting Jackson

Like much of the Southeastern U.S., Jackson is beginning to experience climate shifts attributed to global warming and rising atmospheric carbon levels. Some of the changes include:

Rising Temperatures

  • Average temperatures increased 1-2°F in recent decades
  • Summers feeling hotter and longer lasting heat waves
  • Higher overnight lows offer less relief

Increased Rainfall

  • Precipitation increased 5-10% in the 20th century
  • More frequent extreme rainfall and flooding events
  • Rain patterns have become more variable

Stronger Storms

  • Tropical storms and hurricanes intensify more rapidly
  • Severe thunderstorms spawn heavier rain and wind
  • Peak tornado season extended due to warmer springs

Earlier Springs

  • Springs arrive 10-14 days earlier than in the 20th century

Longer Growing Season

  • Warmer weather extends the freeze-free growing season by 2-3 weeks
  • Farmers can grow and harvest more crops each year
  • But crops also face more heat stress and droughts

Milder Winters

  • Shorter periods of cold winter temperatures
  • Reduced frequency of winter storms and ice/snow
  • But spells of extreme cold still occur due to polar vortex dips

Increased Wildfires

  • Drier autumns and sporadic rainfall raise wildfire risks
  • Forest, brush, and grassland fires occurring more often

More Ozone Pollution

  • Rising temperatures increase ground-level ozone production
  • Poor air quality during heat waves and stagnant conditions

New and Expanding Pests

  • Warmer winters enable some insects to survive and breed year-round
  • Mosquitoes, ticks, roaches flourishing; diseases spread more
  • Some weeds and invasive plants also expand their ranges

Challenges for Agriculture

  • Longer growing season but also more pests, ozone damage, and extreme weather
  • Summer heat stress reduces crop yields
  • More irrigation needed to offset droughts
  • Farmers adjusting with more heat/drought tolerant varieties

Strains on Water Resources

  • Increasing rainfall variability and more frequent droughts
  • Rising water demands for irrigation, energy production, and drinking
  • Falling water tables and reservoir levels during dry years

Adapting to Jackson’s Changing Climate

Citizens, businesses, and government in Jackson are taking steps to adapt to the changing climate conditions:

Cooling and Energy Efficiency

  • Expanding shade tree cover in neighborhoods
  • Weatherizing homes better with insulation and sealing
  • Encouraging green roofs and cool roofs that reflect sunlight
  • Upgrades to AC systems to handle higher peak temperatures

Stormwater Management

  • Improving drainage systems to control heavier rainfall
  • Building bioswales, rain gardens, and retention basins
  • Implementing projects to reduce urban flood risks

Emergency Preparedness

  • Expanding cooling centers to protect vulnerable residents in heat waves
  • Improving early warning systems for tornadoes, floods, hurricanes
  • Hardening infrastructure against extreme weather impacts

Sustainable Agriculture

  • Developing heat, drought, and disease resistant crop varieties
  • Promoting soil health practices to conserve moisture
  • Expanding irrigation infrastructure like canals and reservoirs
  • Diversifying agriculture with alternative crops and livestock

Water Conservation

  • Removing wasteful fixtures and appliances, rainwater harvesting
  • Reducing leakage in delivery pipes
  • Building new aquifers and raising dam capacities
  • Promoting xeriscaping landscapes with native plants

Public Health Initiatives

  • Monitoring and treating diseases like West Nile amplified by climate change
  • Expanding access to quality air conditioning as heat shield
  • Addressing links between mental health and climate anxiety
  • Improving nutritional programs to combat food insecurity

By taking proactive measures to adapt to the changing climate, Jackson can build resilience and continue thriving environmentally, economically, and culturally for generations to come.

The city’s renowned Southern hospitality will surely persevere, even in an altered climate.
