Study Notes
Climate Change Overview
- Climate change is a long-term warming of the planet, which is primarily caused by the increasing levels of greenhouse gases in the Earth's atmosphere.
Factors Contributing to Climate Change
- Natural causes: include volcanic eruptions, changes in Earth's orbit, and variations in the Sun's energy output
- Anthropogenic causes: include human activities such as burning fossil fuels, deforestation, and land-use changes
Natural Causes of Climate Change
- Volcanic eruptions emit natural aerosols, such as sulfur dioxide and ash, into the atmosphere
- Milankovitch theory proposes that variations in Earth's orbit, axial tilt, and precession combine to produce changes in the amount of solar energy that reaches the Earth
Anthropogenic Changes and Climate Change
- Burning fossil fuels, such as coal and oil, releases carbon dioxide and other greenhouse gases into the atmosphere
- Carbon dioxide traps heat and contributes to warming the air near the surface
- Deforestation and land-use changes lead to the release of stored carbon into the atmosphere
Greenhouse Gases and Aerosols
- Greenhouse gases, such as carbon dioxide and methane, trap heat and warm the planet
- Aerosols, such as sulfur dioxide and ash, can reflect sunlight back into space and cool the planet
Volcanic Eruptions and Climate Change
- Volcanic eruptions emit sulfur dioxide and ash, which can reflect sunlight and cool the planet
- Large-scale volcanic eruptions can lead to significant cooling of the planet for several years
