Study Notes
Global Warming
- Refers to the increase in average global temperature over time.
- Measured across the entire Earth's surface, typically over a year.
Climate Change
- Refers to the climatological changes caused by the increased energy in the Earth's system.
- Includes long-term changes in global weather patterns and temperatures.
Consequences of Climate Change
- Rising Sea Levels: Melting glaciers and ice sheets contribute to rising sea levels.
- Extreme Weather Events: Climate change increases the frequency and severity of extreme weather like hurricanes, heatwaves, wildfires, droughts, floods, and heavy precipitation.
- Ecosystem Impacts: Ecosystems are disrupted, affecting biodiversity. Rising temperatures, changes in precipitation, and ocean acidification alter habitats, forcing species to relocate or face extinction.
- Human Health: Climate change poses health threats, including heat-related illnesses, respiratory problems, and the spread of infectious diseases.
- Food & Water Security: Reduced crop yields and increased food insecurity due to climate change impacts on agriculture.
Addressing Climate Change
- Renewable Energy: Transitioning from fossil fuels to renewable energy sources like solar, wind, and hydropower is crucial to reduce greenhouse gas emissions.
- Energy Efficiency: Improving energy efficiency in buildings, transportation, and industry is essential to reduce energy consumption.
- Forest Protection & Restoration: Forests absorb carbon dioxide from the atmosphere. Protecting and restoring forests is a vital step in combating climate change.
- Adaptation: Implementing adaptation measures like flood control, drought-resistant crops, and early warning systems helps communities cope with climate change effects.
Key Policy Issues
Greenhouse Gas Emissions Reduction
- Setting Targets and Timelines: Defining specific greenhouse gas (GHG) emission reduction goals with realistic timelines is critical.
- Policy Instruments: Various policy instruments can be employed to reduce GHG emissions.
- International Cooperation: Addressing climate change effectively requires international collaboration due to the global nature of GHG emissions.
Adapting to Climate Change Impacts
- Investing in Infrastructure Resilience: Building resilient infrastructure to withstand rising sea levels, extreme weather, and water scarcity is crucial.
- Climate-Smart Agriculture: Supporting sustainable agricultural practices like drought-resistant crops and water-efficient irrigation helps ensure food security.
- Coastal Area Management: Protecting coastal communities from rising sea levels and storm surges requires investing in seawalls, flood defenses, and relocation strategies.
