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.
