Study Notes

Causes Of Climate Change

Greenhouse Gas Emissions:
- Carbon dioxide (CO2) from fossil fuels (coal, oil, natural gas).
- Methane (CH4) from agriculture (livestock digestion, rice production) and landfills.
- Nitrous oxide (N2O) from fertilizers and industrial processes.
Deforestation:
- Reduces carbon absorption by trees.
- Land conversion for agriculture and urban development.
Industrial Activities:
- Emissions from manufacturing and energy production.
- Release of pollutants and greenhouse gases.
Transportation:
- Vehicles emit CO2 and other pollutants.
- Shipping and aviation contribute significantly to emissions.
Agricultural Practices:
- Use of fertilizers and pesticides leads to emissions.
- Livestock farming produces significant methane.
Natural Factors:
- Solar radiation changes.
- Volcanic eruptions can temporarily cool the climate but also emit CO2.

Effects On Weather

Increased Temperatures:
- Global warming leads to more frequent heatwaves.
- Alteration of seasonal patterns.
Changes in Precipitation:
- More intense rainfall and flooding in some regions.
- Droughts in others due to altered weather patterns.
Extreme Weather Events:
- Higher frequency of hurricanes, typhoons, and cyclones.
- Increased intensity of storms.
Ocean Changes:
- Rising sea temperatures affect weather systems.
- Changes in ocean currents can shift weather patterns globally.
Glacial and Snow Melt:
- Reduction in snowpack affects water supply.
- Rising sea levels due to melting glaciers contribute to coastal flooding.
Ecosystem Impact:
- Shifts in habitats affecting species distribution.
- Increased risk of wildfires in dry areas.

Causes Of Climate Change

Greenhouse Gas Emissions:
- Carbon dioxide (CO2) is primarily released from the combustion of fossil fuels like coal, oil, and natural gas, significantly increasing atmospheric concentrations.
- Methane (CH4) emissions stem from livestock digestion (enteric fermentation), rice farming, and decomposing organic matter in landfills, contributing to a potent greenhouse effect.
- Nitrous oxide (N2O) is released from fertilizers and industrial processes, possessing a higher heat-trapping ability than CO2.
Deforestation:
- Trees absorb CO2, so deforestation diminishes this carbon capture, exacerbating global warming.
- Land conversion for agriculture and urban expansion further reduces forests, increasing carbon levels in the atmosphere.
Industrial Activities:
- Manufacturing and energy production processes emit substantial amounts of greenhouse gases and pollutants.
- Many industries contribute not only CO2 but also other hazardous emissions impacting air quality.
Transportation:
- Automobiles, trucks, and buses are major CO2 and pollutant sources through fossil fuel combustion.
- The shipping and aviation sectors are significant contributors, with aviation having a high per-passenger emission rate.
Agricultural Practices:
- Excessive use of fertilizers leads to nitrous oxide emissions; meanwhile, livestock farming is responsible for considerable methane output due to digestion processes.
Natural Factors:
- Solar radiation fluctuations can influence climate systems, though changes are typically gradual.
- Volcanic eruptions can temporarily cool the climate by injecting ash into the stratosphere, but they can also release substantial CO2.

Effects On Weather

Increased Temperatures:
- Global warming is linked to an uptick in heatwaves, disrupting local climates and ecosystems.
- Seasonal patterns, such as flowering times and migration, are altered due to changing temperature regimes.
Changes in Precipitation:
- Regions may experience more intense rainfall leading to flooding, while others suffer from droughts due to shifted precipitation patterns caused by climate change.
Extreme Weather Events:
- Hurricanes, typhoons, and cyclones are becoming more frequent and intense, intensifying their destructive potential.
Ocean Changes:
- Rising sea temperatures lead to weather pattern shifts, affecting global climate systems.
- Changes in ocean currents can disrupt established weather patterns, impacting fishing and local climates.
Glacial and Snow Melt:
- Melting glaciers reduce snowpack, essential for seasonal water supply, especially in summer months.
- Rising sea levels from glacial melt result in coastal flooding and erosion, threatening coastal communities.
Ecosystem Impact:
- Habitat shifts disrupt ecosystems, leading to changes in species distribution and survival rates as organisms struggle to adapt.
- Increased risks of wildfires in prone areas are linked to drier conditions and higher temperatures, resulting in ecological and economic consequences.

Causes Of Climate Change

Greenhouse gases such as carbon dioxide (CO2) from fossil fuels are the primary drivers of climate change.
Major sources of methane (CH4) include livestock, rice cultivation, and landfill emissions, contributing significantly to global warming.
Nitrous oxide (N2O) is predominantly released from agricultural fertilizers and various industrial processes, further exacerbating climate change.
Deforestation diminishes the Earth’s ability to absorb CO2 since trees play a crucial role in carbon sequestration.
Land-use changes, driven by agriculture and urbanization, lead to increased carbon emissions.
Industrial processes contribute additional greenhouse gas emissions, including hydrofluorocarbons (HFCs) that have potent warming effects.
Agricultural practices, especially livestock farming, release methane, while the use of nitrogen-based fertilizers escalates nitrous oxide levels.
Dependence on non-renewable energy sources heightens the carbon footprint, underscoring the need for a transition to renewable energy options like solar, wind, and hydroelectric power.

Effects On Weather

Global average temperatures are increasing, resulting in more frequent and intense heatwaves and altered seasonal cycles.
Extreme weather events, including hurricanes and cyclones, have become more prevalent and severe due to climate change.
Some regions experience heightened precipitation leading to flooding, while others face increased drought conditions.
Rising sea temperatures contribute to the intensity of hurricanes, while ocean acidification threatens marine ecosystems and weather patterns.
Melting polar ice caps and glaciers are major contributors to rising sea levels, posing significant risks to coastal areas through flooding and erosion.
Ecosystems are disrupted as habitats change and species migrate, leading to increased vulnerability and potential loss of biodiversity.
Agriculture faces challenges from variable rainfall patterns, potentially reducing crop yields and increasing the spread of pests and diseases in warmer conditions.
