    Study Notes

    Weather vs. Climate

    • Weather describes short-term atmospheric conditions (days to weeks), encompassing temperature, precipitation, humidity, and wind.
    • Climate represents long-term average weather patterns (30 years or more) in a region. It determines the types of plants and animals that can survive there.
    • Climate is what you expect; weather is what you get.

    Climate Zones and Ecoregions

    • Climate zones are determined by temperature, precipitation, and plant/animal communities.
    • Ecoregions are broader, also considering human activities, soil types, and landforms, in addition to climate and organisms.

    Factors Affecting Climate

    • Proximity to large bodies of water moderates temperature.
    • Latitude (distance from the equator) influences solar radiation intensity and temperature.
    • Ocean and air currents distribute heat globally.
    • Land formations and elevation impact local climates.

    Solar Energy and the Greenhouse Effect

    • The sun is Earth's primary energy source.
    • About 70% of incoming solar radiation is absorbed by Earth's surface, warming it.
    • The rest (30%) is reflected back into space.
    • The absorbed energy is re-radiated as infrared radiation (heat).
    • The greenhouse effect is a natural process where greenhouse gases and clouds absorb and re-radiate some of this infrared energy back towards Earth, maintaining a habitable temperature.
    • Without the greenhouse effect, Earth's average temperature would be -18°C. With it, it's ~15°C.

    Greenhouse Gases

    • Greenhouse gases are atmospheric gases composed of two or more elements. Examples include CO2, CH4, N2O, and H2O.
    • Carbon Dioxide (CO2): Represents 0.038% of the atmosphere.
    • Pre-Industrial levels: 280 ppm.
    • Current levels: 385 ppm.
    • Oceans and vegetation act as carbon sinks.
    • Water Vapor (H2O): Accounts for ~2/3 of the greenhouse effect.
    • Methane (CH4): ~23 times more potent than CO2 as a greenhouse gas, primarily from natural sources and/or agriculture.
    • Nitrous Oxide (N2O): ~300 times more potent than CO2 as a greenhouse gas, primarily from industry and agricultural sources.

    Feedback Loops and Anthropogenic Impacts

    • Feedback loops are processes where one change results in additional impacts that reinforce the initial condition.
    • Anthropogenic greenhouse gases are those emitted by human activities.

    Anthropogenic Greenhouse Gas Sources

    • Carbon Dioxide (CO2): Primarily from burning fossil fuels (coal, oil, and natural gas) and deforestation.
    • Methane (CH4): Associated with agriculture (livestock, rice paddies), coal mining, and landfills.
    • Nitrous Oxide (N2O): Found in fertilizers and livestock feed.

    Evidence of Climate Change

    • Rising Temperatures: Global average temperatures have increased by 0.6 °C since 1970. Canada has seen a 1°C rise in the last 55 years; parts of the Yukon have experienced a substantially greater increase (2.5°C).
    • Melting Glaciers and Ice Sheets: Glaciers are shrinking worldwide. Greenland's ice melt is accelerating.
    • Rising Sea Levels: Melting land ice contributes significantly to rising sea levels, which threatens coastal areas. Ocean ice melt does not.
    • Changes in Severe Weather: Increased frequency and intensity of heat waves, storms.
    • Changes in Precipitation Patterns: Some regions experience more rainfall, others less, which can alter water resources and agriculture.
    • Shifting Seasons: Earlier snowmelt, longer growing seasons, fewer cold days in some regions, and changes in timing of biological processes (migration, breeding).
    • Changing Ecosystems: Species adapting to changing conditions by migrating or shifting ranges, affecting biodiversity.
