Study Notes
Global Warming and Climate Change
- Global temperatures have increased since the 20th century
- Global warming is a long-term trend in Earth's temperature since the pre-industrial period
- Human activities, primarily burning fossil fuels, are the main cause of global warming
- Greenhouse Effect: Natural process where greenhouse gases (GHGs) trap heat near Earth's surface, preventing freezing
- Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), water vapor (H2O), and chlorofluorocarbons (CFCs)
- Human activities have increased GHG levels, causing global warming
Greenhouse Gas Emissions
- Carbon dioxide (CO2) is the primary GHG emitted by human activities
- Burning fossil fuels for energy and transportation increases CO2
- Cement, iron, and steel production also release CO2
- Deforestation reduces CO2 absorption
- Methane is produced from livestock, natural gas production, rice cultivation, and landfill waste
- Nitrous oxide comes from commercial and organic fertilizers, and from burning fossil fuels
Greenhouse Gas Emissions Throughout the Life Cycle
- GHGs are released at every stage of a product's life cycle: extraction, transport, manufacturing, waste management (especially incineration), and breakdown
- Microplastics in the ocean may interfere with the ocean's ability to absorb carbon dioxide
Climate and Climate Change
- Climate: Long-term average of temperature, humidity, and rainfall patterns over seasons, years, or decades
- Climate change: Long-term change in climate
- Climate changes over the last 650,000 years are due to changes in Earth's orbit
- Recent climate changes are mainly caused by global warming
Climate Change Effects
- Impacts of global warming include melting ice, rising sea levels, increased temperatures, more frequent wildfires, longer periods of drought, shift in blooming times, and stronger/more frequent typhoons or hurricanes
Coral Bleaching
- Global warming causes coral bleaching
- Coral reefs are made of polyps with zooxanthellae (algae)
- Warmer ocean temperatures cause zooxanthellae to expel from corals, leaving them without color (bleaching)
- Prolonged stress can kill coral
Technologies and Actions To Reduce Global Warming/Climate Change
- Carbon Footprint: Total greenhouse gas emissions caused directly and indirectly by an individual, organization, event, or product
- CO2 Capture Plant: Plants extract CO2
- Electric vehicles (EVs) produce less emissions than conventional vehicles
- Offsets: Voluntary payments to reduce greenhouse gases in the atmosphere
- Emissions Trading (cap and trade system): Governments set a maximum limit on pollution (cap) and companies can buy/sell allowances.
- Glasgow Climate Pact: Aims to limit global average temperature rise to 1.5°C, including phasing down coal use, halting deforestation and ensuring financing for developing nations.
- Ecotourism: Sustainable form of natural resource-based tourism focused on ethical and low-impact methods for observing nature and its conservation.
Tools for Environmental Management
- LCA (Life Cycle Assessment): Process of measuring environmental impact of a product or service throughout its life cycle
- EIA (Environmental Impact Assessment): Tool used to identify environmental, social and economic impacts of a project prior to decision-making
- GIS (Geographic Information Systems): Maps land use, vegetation, and other elements for informed decisions in architecture and natural resource management.
