Study Notes
Climate Change
- Describes global warming and its effects on the Earth's climate system
- Also includes previous long-term changes to the Earth's climate
Causes of Climate Change
- Primarily caused by humans burning fossil fuels
- Fossil fuel use, deforestation, and some agricultural and industrial practices add to greenhouse gases
- Notable greenhouse gases: carbon dioxide and methane
Effects of Greenhouse Gases
- Absorb heat that the Earth radiates after warming from sunlight
- Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming
Impacts of Climate Change
- Deserts are expanding
- Heat waves and wildfires are becoming more common
- Amplified warming in the Arctic has contributed to:
- Melting permafrost
- Glacial retreat
- Sea ice loss
- Higher temperatures are a consequence of climate change
