Climate Action

The Earth's climate has changed in the past. Temperature and carbon dioxide levels have fluctuated due to natural variation like changes in the earth's orbit or factors such as volcanic eruptions. Modern climate change is occurring at an unprecedented and alarming rate. The main driver behind climate change today is human activity, which has increased carbon dioxide in the air to levels higher than anything seen in at least 800,000 years. An increase in greenhouse gases like carbon dioxide causes an increase in the earth's temperature.

Climate change has and will continue to present risks like higher frequency and intensity of hurricanes, forest fires, more extreme and record breaking temperatures, increased precipitation and flood risk, drought, rising sea levels, melting glaciers, loss of biodiversity, and potential risks that climate models will not be able to predict. 

For millenia, atmospheric carbon dioxide had never exceeded 300 parts per million.

Acting on climate change means both reducing our use of fossil fuels and proactively planning to adapt to future changes. More action is needed at both the state and federal levels. Citizens and businesses have a role to play in demanding effective action at all levels of government, using the climate action programs that are currently available, and making personal and business decisions that reduce energy waste.

Global climate change presents serious threats to our environment, human health, economy and equality, biodiversity, and national security.

The National Climate Assessment outlines particular threats climate change poses to Wisconsin and the Midwest as extreme heat, heavy downpours, and flooding that will affect infrastructure, health, agriculture, forestry, transportation, and air and water quality. Climate change will also exacerbate a range of risks to the Great Lakes.

The Impacts of Climate Change on Human Health Diagram

  • Human Health: lower air quality that could increase risk of lung and cardiovascular diseases, heat-related illnesses and premature deaths, and drinking water contamination
  • Community Vulnerability & Adaptation: negative impacts on urban heat island effect, homeless population, and tribal people who rely on threatened resources
  • Agriculture: reduced crop yields, wetter conditions that increase soil erosion, and more favorable conditions for pests and pathogens
  • Biodiversity & Ecosystems: faster rates of species decline and extinction, threats to ecological services like flood control, water purification, and crop pollination, and risk to freshwater resources from the Great Lakes 
  • Forestry: invasive species and reduced biodiversity, increase in tree mortality and decrease in forest productivity, challenges to timber and recreation industries, and threats to plants, animals, and resources important to tribal communities
  • Transportation & Infrastructure: increased flooding and heat stress could damage stormwater management systems and transportation infrastructure, as well as result in combined sewer overflows
  • Climate and Equity Plan:
    • By 2030, Milwaukee aims to reduce community greenhouse gas emissions by at least 45%
    • By 2050, or sooner, Milwaukee aims to achieve net zero greenhouse gas emissions
