    What is global warming?

    The long-term heating of Earth's climate system due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

    What is the greenhouse effect?

    A natural process that warms Earth's surface. The Sun's energy reaches the Earth's atmosphere, some is reflected back to space, and the rest is absorbed and re-radiated by greenhouse gases.

    What causes global warming?

    The primary driver is the burning of fossil fuels for energy production, transportation, and industry. Deforestation, agricultural practices, and industrial processes also release significant amounts of greenhouse gases.

    What are the impacts of global warming?

    Rising global temperatures, more frequent and intense heat waves, changes in precipitation patterns, melting glaciers, sea level rise, ocean acidification, disruptions to ecosystems, more intense storms, and impacts on human health.

    How do feedback loops affect global warming?

    Feedback loops amplify the effects of global warming. For example, melting permafrost releases methane, further increasing the greenhouse effect. Deforestation reduces the Earth's capacity to absorb carbon dioxide, accelerating warming.

    What are the consequences of continued global warming?

    Sea level rise threatening coastal areas, changes in agricultural yields impacting food security, spread of diseases, displacement of populations due to extreme weather events.

    What are some mitigation strategies for global warming?

    Transitioning to renewable energy sources (solar, wind, hydro) to reduce reliance on fossil fuels.

    What is methane and why is it a concern?

    A potent greenhouse gas released from sources like livestock farming, natural gas leaks, and thawing permafrost.

    Study Notes

    Definition of Global Warming

    • Global warming refers to the long-term heating of Earth's climate system observed since the pre-industrial period (1850-1900) due to human activities, primarily fossil fuel burning, increasing heat-trapping greenhouse gas levels in Earth's atmosphere.

    Greenhouse Effect

    • The greenhouse effect is a natural process warming Earth's surface. Solar energy enters the atmosphere, some reflects back to space, and the rest is absorbed and re-radiated by greenhouse gases.
    • Without the greenhouse effect, Earth's average temperature would be significantly colder, making it uninhabitable for most life forms.
    • The enhanced greenhouse effect results from increased greenhouse gas concentrations, trapping more heat and causing global warming.

    Causes of Global Warming

    • Burning fossil fuels (coal, oil, and natural gas) for energy, transportation, and industry is the primary driver of global warming.
    • Deforestation, agricultural practices, and industrial processes release significant amounts of greenhouse gases (carbon dioxide, methane, nitrous oxide) into the atmosphere.
    • Increased livestock farming contributes methane emissions, a powerful greenhouse gas.

    Impacts of Global Warming

    • Rising global temperatures occur.
    • More frequent and intense heat waves are experienced.
    • Precipitation patterns change, causing both droughts and floods.
    • Melting glaciers and polar ice contribute to sea level rise.
    • Ocean acidification harms marine life.
    • Ecosystems and biodiversity are disrupted.
    • More frequent and intense storms (hurricanes, typhoons) arise.
    • Human health is impacted, such as heat-related illnesses increasing.

    Feedback Loops

    • Global warming creates feedback loops amplifying its effects.
    • Melting permafrost releases methane, further increasing the greenhouse effect.
    • Deforestation reduces Earth's capacity to absorb carbon dioxide, accelerating warming.

    Consequences of Continued Global Warming

    • Sea level rise threatens coastal communities and infrastructure.
    • Agricultural yields change, impacting food security.
    • Diseases spread, potentially affecting global human health.
    • Displacement of populations due to extreme weather and environmental changes occurs.

    Mitigation Strategies

    • Shifting to renewable energy (solar, wind, hydro) reduces reliance on fossil fuels.
    • Improving energy efficiency in buildings and transportation systems is crucial.
    • Sustainable land-use practices, like reforestation, help.
    • Developing and implementing carbon capture and storage technologies.
    • Global cooperation and policy changes are needed to address the issue.

    Adaptation Strategies

    • Climate-resilient infrastructure (flood defenses) is vital.
    • Improving water management systems handles changing precipitation patterns.
    • Implementing early warning systems for extreme weather events improves preparedness.
    • Developing heat-resistant crops adapts to changing temperatures.
    • Protecting biodiversity and ecosystems is a key component of adaptation.
