Study Notes

Fossil Fuels

Pros: Existing infrastructure, high energy content, relatively cheap, relatively abundant.
Cons: Finite resource (unsustainable), habitat destruction, transport and combustion emissions (CO2, NOx, SO2), impacting aquatic ecosystems (water consumption and thermal pollution).

Nuclear Power

Pros: No CO2 emissions, fewer deaths than fossil fuels (compared to coal mining accidents, urban air pollution).
Cons: Radioactive waste (thousands of years), risk of accidents (Chernobyl, Fukushima), potential for nuclear weapons, high capital and decommissioning costs.

Renewable Energy Sources

Solar Power:
- Pros: Useable in remote areas, low running cost, no air pollution during operation, sustainable, renewable.
- Cons: Sunlight dependence (varies regionally and seasonally), high installation costs, pollution during production, no electricity at night.
Wind Power:
- Pros: Renewable, sustainable, abundant, usable in remote areas, no emissions, low operational cost.
- Cons: Wind dependence, noise pollution, aesthetic concerns, bird and bat fatalities, high manufacturing/installation costs, need for electricity storage.
Hydropower:
- Pros: Low running cost, sustainable, increased water resources, flood risk reduction, habitat creation, no air pollutants.
- Cons: High capital costs, displacement of people, habitat destruction (loss of biodiversity), emission of greenhouse gases (CO2, methane) due to decomposition.
Geothermal Power:
- Pros: Cheap operation, low CO2 emissions, reliable (in some areas), sustainable.
- Cons: High drilling costs, potential release of poisonous gases, limited to areas near volcanic activity (tectonic plate boundaries).

Comparing Energy Sources

Comparing fossil fuels and renewables: Fossil fuels are cheaper and have readily available infrastructure but are non-sustainable and highly polluting whereas renewables offer sustainability and reduced pollution but can be unpredictable and expensive initially.

Reasons for Changing Energy Sources

Climate Change: Many energy sources contribute to pollutant emissions, particularly greenhouse gases. These increase global warming. Renewables are being favored due to their lower emissions.
Renewability: Fossil fuels are finite, unlike renewable energy. The world is moving towards more sustainable choices.

Energy Security Factors

Distribution: Uneven global distribution of resources leads to interdependence.
Threats: Political instability/conflict, accidents/natural disasters, terrorist attacks, resource overuse.
Mitigation Strategies: Energy self-sufficiency, diversification of sources, exploiting indigenous resources, reduced demand/increased efficiency, reduced interdependence.

Factors Affecting Energy Choices

Availability: Depends on geographical location, geology (fossil fuel abundance, geothermal access), topography (wind, hydropower suitability).
Sustainability: Long-term considerations regarding resources.
Scientific/Technological Developments: Innovations increase affordability/accessibility.
Cultural Attitudes: Nature-centered communities may prioritize lower energy use.
Politics: Government policies reflect values and respond to international agreements.
Economics: Cost-effectiveness; economic status may restrict options.
Environmental Impact: Some countries prioritize low-emission energy sources.

Climate vs. Weather

Climate: Average weather patterns over a long period (regional scale).
Weather: Current conditions over a short period (local scale).

Earth's Climate Factors

External: Solar radiation (variations in emission, 11-year cycle), Earth's tilt and orbit (Milankovitch Cycles, impacting seasonal changes), influencing solar energy absorption and distribution.
Internal: Atmospheric and ocean circulation (equator-pole heat transfer), wind patterns (pressure differences).
Greenhouse Gases: Trap heat, warming the planet. Increased concentrations elevate temperatures.
Volcanic Activity: Short-term impact, reflecting solar radiation and causing cooling.

Feedback Mechanisms

Positive Feedback Loops: Enhance global warming.
- Water vapor: Increased evaporation leads to more greenhouse gases.
- Ice albedo: Melting ice reduces reflectivity, absorbing more heat.
- Permafrost thaw: Releases methane, boosting warming.
- Carbon dioxide solubility: Declining solubility results in more CO2 in the atmosphere.
Negative Feedback Loops: Reduce global warming.
- Plant photosynthesis: Increased CO2 absorption can reduce temperatures.
- Cloud cover: Low clouds reflect radiation into space (cooling), while high clouds retain heat.

Atmospheric Circulation

Tricellular Model: Explains heat transfer within the atmosphere.
Hadley Cell: Equatorial air rises, moves to poles, and returns to the equator, cycling for heat transfer.
Ferrel Cell: Air moves between Hadley and Polar cells, influences regional precipitation.
Polar Cell: Cool air descends, pushing air back to the Ferrel cell, completing the cycle.

El Niño Phenomenon

A climate pattern disrupting ocean and atmospheric conditions, particularly affecting the Pacific Ocean, leading to effects globally.

Climate Change Impacts

Higher Temperatures: Increased temperatures globally from 1880–2013 (0.85°C rise), with predicted rises to 2100 contingent on emission levels (reduced vs. high emissions).
Hydrological Cycle Impacts: Changes in precipitation patterns (more in some areas, less in others). More evaporation, leading to more/less intense and longer-lasting weather events.
Sea Level Rise: Thermal expansion of oceans, melting snow/ice, projected rise in sea level from 26cm to 82cm by 2100.
Water Resources: Reduced water resources in some regions, increased droughts, reduced glacier/snow water, affects agriculture, biodiversity and human populations.
Flooding: Increased precipitation results in more frequent and intense floods, causing damage, displacement, water contamination and mortality.
Agriculture/Fisheries: Altered climatic conditions can impact yields. Warmer water affects fish species distribution, range, and spawning periods.
Ecosystems/Biodiversity: Regional climate shifts, resulting in species extinction, range shifts/migration patterns.
Coastal Systems: Increased storm intensity, rising sea level, salinization, habitat loss, infrastructure and displacement damage, and overall livelihood threats.
Human Impacts: Impacts on food and water security, disease risk, extreme weather impacts on health.

Climate Change Viewpoints

Scientific Consensus: Climate change is occurring, mainly human-induced.
Climate Sceptics: Deny human causation, arguing for natural cycles.
Climate Advocators: Emphasize human causes and advocate for major policy changes.

Tipping Point

Tipping Point: A change in system properties beyond which a system abruptly reorganizes, potentially irreversibly, even if drivers are removed.

Climate Change Models

Model Use: Climate models use mathematical formulas to predict future climate changes.
Model Uncertainty: Limitations stemming from incomplete data sets, measurement protocols, positive/negative feedback loops, ocean circulation, tipping points, and predictions of human behavior/volcanic activity.
IPCC Use: The models are used for various scenarios (e.g., if greenhouse gas emissions are reduced/increase) to aid in resource allocation.

Mitigation vs. Adaptation

Mitigation: Reducing climate change causes (emissions reduction, carbon sequestration).
Adaptation: Adjusting to the effects of climate change (e.g. infrastructure changes, drought resistance crops)

Kyoto Protocol

Strengths: Increased global attention to emission reduction. Some countries met/exceeded targets.
Weaknesses: Major emitters did not ratify, emerging economies were often not bound, goals not ambitious enough, enforcement lacked effectiveness.

Barriers to Mitigation/Adaptation

Mitigation: High upfront cost, consensus/political will issues, access to green technologies, resistance to lifestyle changes
Adaptation: Limited funding, lack of data/research, poor governance, long implementation timelines

Addressing Barriers

Mitigation: Offer financial incentives, strengthen international cooperation, invest in research, raise awareness.
Adaptation: Establish climate funds, train communities, improve reporting and understanding via data sharing, integrate adaptation measures into policy.
