Unit 1450: Climate Change and Public Health

1. Introduction to Climate Change

1.1 Basic Concepts

• Definition of climate change
• Difference between climate change and weather

1.2 Greenhouse Gases and Global Warming

• Key greenhouse gases (CO2, methane, nitrous oxide, etc.)
• Greenhouse effect mechanism
• Evidence of global warming trends

1.3 Human Activities Impacting Climate

• Fossil fuel combustion
• Deforestation
• Industrial processes
• Agriculture

1.4 Environmental Impacts

• Rising sea levels
• Melting glaciers and polar ice
• Changes in weather patterns
• Biodiversity loss

2. Health Impacts of Climate Change

2.1 Direct Health Effects

• Heat-related illnesses (heat stroke, dehydration)
• Injuries and deaths due to extreme weather events (storms, floods)

2.2 Indirect Health Effects

• Vector-borne diseases (malaria, dengue, Lyme disease)
• Air quality and respiratory illnesses (asthma, allergies)
• Food and water security affecting nutrition and waterborne diseases

2.3 Mental Health Implications

• Stress, anxiety, and depression related to climate disasters
• Displacement and trauma

3. Vulnerable Populations and Climate Change

3.1 Children

• Greater susceptibility to malnutrition and disease

3.2 Elderly Individuals

• Reduced thermoregulation and pre-existing conditions

3.3 Low-income Communities

• Limited resources for adaptation
• Higher exposure to environmental hazards

3.4 Individuals with Pre-existing Health Conditions

• Amplified effects of heat, pollution, and infections

4. Adaptation Strategies for Public Health

4.1 Early Warning Systems

• Heatwave alerts
• Disease outbreak monitoring

4.2 Urban Planning

• Green spaces to reduce urban heat islands
