    GEDB Global Warming: Extreme Heat Can Impact Our Lives in Many Ways (Lesson 3 of 5)

    GEDB Global Warming: Extreme Heat Can Impact Our Lives in Many Ways (Lesson 3 of 5)

    Overview

    Students will learn how climate change poses risks to human health. Students will realize we need to safeguard our communities by protecting people’s health and quality of life from climate change impacts. The standards tagged are for the entire series of lessons as a whole. This lesson was developed by Marty Ervin as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

    Lesson Plan

    Description

    Students will learn how climate change poses risks to human health. Students will realize we need to safeguard our communities by protecting people’s health and quality of life from climate change impacts.


    Content

    Learning Targets and Criteria for Success

    Objectives:  Students will learn how climate change poses risks to human health.  Students will realize we need to safeguard our communities by protecting people’s health and quality of life from climate change impacts.

    Teaching Point:   

    Human health — Effects of global warming on humans’ health includes exacerbating health problems that already exist, increases in ill-health in many regions and especially in developing countries with low-income, and greater likelihood of injury, disease, and death. These risks are due to more intense heat waves and fires, and increased likelihood of under-nutrition resulting from diminished food production in poor regions. As global temperatures rise, normal human activities are compromised, such as farming or working outdoors. Risks from lost work capacity and reduced labor productivity in vulnerable populations also increase, as well as increased risks from vector-, food-, and water-borne diseases.

     

    Lesson Procedures: 

    Students will complete the warmup on the respiratory system.  This will provide key details and review of parts of the respiratory system.  Students will then read the handout on how extreme heat can impact our health.  The handout provides a climate-health connection and background on the burning of fossil fuels.  They will answer the worksheet as they read. We will end the class with group discussion on how other countries of the world could reduce the impact of global warming towards their respiratory system.

    Independent Activity: Handout:  Background and the Climate – Health Connection

     When we burn fossil fuels, such as coal and gas, we release carbon dioxide (CO2).  CO2 builds up in the atmosphere and causes Earths temperature to rise, much like a blanket traps in heat. This extra trapped heat disrupts many of the interconnected systems in our environment.  Climate change also affects human health by increasing the frequency and intensity of extreme heat events. Increases in the overall temperature of the atmosphere and oceans associated with climate change cause changes in wind, moisture, and heat circulation patterns. These changes contribute to shifts in extreme weather events, including extreme heat events.

    Extreme heat events can be dangerous to health even fatal. These events result in increased hospital admissions for heat-related illness, as well as cardiovascular and respiratory disorders.

    Extreme heat events can trigger a variety of heat stress conditions, such as heat stroke. Heat stroke is the most serious heat-related disorder. It occurs when the body becomes unable to control its temperature. Body temperature rises rapidly, the sweating mechanism fails, and the body cannot cool down. This condition can cause death or permanent disability if emergency treatment is not given. Small children, the elderly, and certain other groups including people with chronic diseases, low-income populations, and outdoor workers have higher risk for heat-related illness.

    Higher temperatures and respiratory problems are also linked. One reason is because higher temperatures contribute to the build-up of harmful air pollutants.

    Many cities across the United States, including St. Louis, Philadelphia, Chicago, and Cincinnati, have seen large increases in death rates during heat waves.

    Collecting and Documenting Evidence of Learning

    Closure:  Group Discussion: 

    What are sources of air pollution in other countries that could impact respiratory health?

    Why would people living in the least developed countries or even rural areas of the United States be most vulnerable to the health impacts of climate change?   How do humans impact air quality?  Why would young children and the elderly be more at risk from air pollution?  Biomagnification is the buildup of pollutants in animals.  Humans are the top of the food chain.  How would biomagnification  negatively impact humans?
