Study Notes
Definition and Causes
- Global climate change refers to the long-term warming of the planet due to an increase in the average global temperature.
- Main causes:
- Greenhouse gases (GHGs): CO2, methane, water vapor, and other gases trap heat in the atmosphere.
- Human activities: burning fossil fuels, deforestation, and land-use changes release large amounts of GHGs.
- Natural factors: volcanic eruptions, changes in Earth's orbit, and solar radiation variations.
Effects of Climate Change
- Temperature increase: Average global temperature has risen by about 1°C since the late 1800s.
- Extreme weather events: More frequent and intense heatwaves, droughts, floods, and storms.
- Sea-level rise: Thawing of polar ice caps and glaciers, leading to coastal erosion and saltwater intrusion into freshwater sources.
- Ecosystem disruption: Changes in species distribution, extinction risks, and disruptions to food chains.
Consequences of Climate Change
- Human health: Increased risk of heat-related illnesses, respiratory problems, and the spread of disease vectors.
- Food security: Changes in temperature and precipitation patterns affect crop yields, food availability, and quality.
- Economic impacts: Damage to infrastructure, increased costs for healthcare and emergency response, and loss of productivity.
Mitigation and Adaptation Strategies
- Reduce GHG emissions: Transition to renewable energy sources, increase energy efficiency, and implement carbon capture and storage.
- Adaptation measures: Implement early warning systems, flood protection infrastructure, and climate-resilient agriculture.
- International cooperation: Global agreements, such as the Paris Agreement, aim to limit global warming to well below 2°C and pursue efforts to limit it to 1.5°C.
Key Terms and Concepts
- Climate change vs. global warming: Climate change encompasses a broader range of changes, including temperature, precipitation, and weather patterns, while global warming specifically refers to the increase in global temperature.
- Climate justice: The concept of fairness and equity in the distribution of climate change impacts, particularly in vulnerable communities.
