Causes and Effects of Global Warming

Study Notes

Causes Of Global Warming

Greenhouse Gas Emissions:
- Carbon dioxide (CO2) from fossil fuel combustion (coal, oil, gas).
- Methane (CH4) from agriculture (livestock, rice paddies) and landfills.
- Nitrous oxide (N2O) from agricultural practices and industrial processes.
Deforestation:
- Loss of trees reduces CO2 absorption.
- Provides habitat for species and affects carbon storage.
Industrial Activities:
- Manufacturing processes release various pollutants.
- Energy consumption in industries contributes to increased emissions.
Agricultural Expansion:
- Land conversion for crops and livestock increases emissions.
- Use of fertilizers releases nitrous oxide.
Transportation:
- Cars, trucks, and airplanes emit significant greenhouse gases.
- Urbanization increases reliance on fossil fuel transportation.

Effects On Ecosystems

Habitat Loss:
- Altered temperature and precipitation patterns disrupt habitats.
- Species migrations and extinctions are observed.
Biodiversity Decline:
- Ecosystems struggle to adapt to rapid climate changes.
- Coral reefs suffer from ocean acidification and increased temperatures.
Altered Weather Patterns:
- Increased frequency of extreme weather events (hurricanes, droughts).
- Affects water supply and food production.
Ocean Changes:
- Rising sea levels threaten coastal ecosystems.
- Marine life is affected by warming waters and acidification.
Shifts in Species Distribution:
- Species migrate poleward or to higher altitudes.
- Impact on predator-prey relationships and ecosystem dynamics.

Climate Change Mitigation

Renewable Energy:
- Transition to solar, wind, and hydropower reduces fossil fuel dependence.
- Energy efficiency improvements in buildings and appliances.
Afforestation and Reforestation:
- Planting trees helps absorb CO2 from the atmosphere.
- Restoration of degraded land improves carbon storage.
Sustainable Agriculture:
- Practices like crop rotation and organic farming minimize emissions.
- Reduction of fertilizer use decreases nitrous oxide release.
Policy and Legislation:
- Implementation of carbon pricing mechanisms (taxes, cap-and-trade).
- International agreements (e.g., Paris Agreement) to set emission reduction targets.
Education and Awareness:
- Promoting sustainable practices among individuals and businesses.
- Increasing public understanding of climate change impacts and solutions.

Causes of Global Warming

Greenhouse gas emissions from burning fossil fuels (coal, oil, gas) are a primary driver. This includes carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
Agricultural practices, including livestock farming and rice cultivation, significantly contribute to methane emissions. Landfills also release substantial methane.
Deforestation reduces the planet's capacity to absorb CO2, exacerbating global warming. It also disrupts habitats and reduces carbon storage.
Industrial processes release various pollutants and contribute significantly to energy consumption and greenhouse gas emissions.
Expanding agriculture, including land conversion for crops and livestock, increases greenhouse gas emissions, especially nitrous oxide from fertilizers.
Transportation, including cars, trucks, and airplanes, emits considerable greenhouse gases, amplified by urbanization and its reliance on fossil fuel-based transport.

Effects on Ecosystems

Habitat loss is widespread due to altered temperatures and precipitation patterns, leading to species migrations and extinctions.
Biodiversity decline is a direct consequence of rapid climate change, impacting ecosystems’ ability to adapt. Coral reefs are particularly vulnerable to warming waters and ocean acidification.
Altered weather patterns resulting from global warming increase the frequency and intensity of extreme events, such as hurricanes and droughts, affecting water supplies and food production.
Ocean changes, including rising sea levels and acidification, threaten coastal ecosystems and marine life.
Shifts in species distribution are observed, with species moving towards the poles or higher altitudes, disrupting predator-prey relationships and ecosystem dynamics.

Climate Change Mitigation

Transitioning to renewable energy sources (solar, wind, hydropower) is crucial for reducing reliance on fossil fuels. Improving energy efficiency in buildings and appliances also plays a key role.
Afforestation and reforestation, i.e., planting and restoring trees, help absorb atmospheric CO2 and enhance carbon storage.
Sustainable agricultural practices, such as crop rotation and organic farming, minimize emissions and reduce fertilizer use (decreasing nitrous oxide release).
Effective climate change mitigation requires strong policy and legislation, including carbon pricing mechanisms (taxes, cap-and-trade) and international agreements like the Paris Agreement.
Public education and awareness are essential to drive change by promoting sustainable practices and fostering a better understanding of climate change impacts and solutions.
