    Study Notes

    Climate Change

    • Carbon dioxide is the main greenhouse gas responsible for trapping heat in the Earth's atmosphere.
    • The primary cause of climate change is the increasing levels of greenhouse gases in the atmosphere, mainly due to human activities.

    Deforestation and Climate Change

    • Deforestation contributes to climate change by releasing stored carbon into the atmosphere and reducing the ability of forests to act as carbon sinks.

    Contributors to Climate Change

    • Burning of fossil fuels is a significant factor contributing to climate change.
    • Human activity, specifically the release of chlorofluorocarbons (CFCs), is a significant contributor to the depletion of the ozone layer.

    Ocean Acidification

    • The primary cause of ocean acidification is the absorption of increasing amounts of carbon dioxide from the atmosphere, which reacts with water to form acid.
