Flashcards

Carbon Dioxide (CO2)

The primary greenhouse gas responsible for trapping heat in the Earth's atmosphere.

Climate Change

The major driver of changing global climate patterns.

Deforestation

The process of removing trees, which reduces the ability of the Earth to absorb carbon dioxide.

Fossil Fuel Combustion

The burning of fossil fuels like coal, oil, and natural gas, which releases carbon dioxide into the atmosphere.

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.
