Study Notes
Carbon Dioxide and Climate Change
- The amount of carbon dioxide in the atmosphere remained constant for most of the past 1,000 years, but changed in the late 18th century.
Contributors to Climate Change
- The biggest contributor to climate change is not specified in the text, but it is commonly known that human activities such as burning fossil fuels, deforestation, and land-use changes are significant contributors.
Reversing Climate Change
- The key to reversing the damage of climate change is not specified in the text, but it is commonly known that reducing greenhouse gas emissions, transitioning to renewable energy, and preserving natural carbon sinks can help mitigate its effects.
The Carbon Cycle
- The process by which carbon moves around the Earth is known as the carbon cycle.
- The carbon cycle involves the circulation of carbon through the atmosphere, oceans, land, and living organisms.
- Sources of carbon in the carbon cycle include fossil fuel burning, land-use changes, and respiration by living organisms.
- Sinks of carbon in the carbon cycle include oceans, forests, and soil, which absorb and store carbon dioxide.
