Causes and Effects of Climate Change

Study Notes

Causes Of Climate Change

Greenhouse Gas Emissions:
- Carbon dioxide (CO2) from burning fossil fuels (coal, oil, natural gas).
- Methane (CH4) from agriculture (livestock) and landfills.
- Nitrous oxide (N2O) from industrial activities and agricultural practices.
Deforestation:
- Trees absorb CO2; cutting them down increases atmospheric CO2 levels.
Industrial Processes:
- Production of cement, chemicals, and metals releases significant greenhouse gases.
Agricultural Practices:
- Use of fertilizers and methane emissions from livestock contribute to climate change.
Land Use Changes:
- Urbanization and conversion of land for agriculture alter natural carbon sinks.

Effects On Weather

Increased Temperatures:
- Global average temperatures rising, leading to heatwaves and altered climate patterns.
Extreme Weather Events:
- Increased frequency and intensity of hurricanes, floods, droughts, and storms.
Changes in Precipitation Patterns:
- More rain in some areas, leading to flooding; less in others, causing droughts.
Ocean Changes:
- Rising sea temperatures and acidification affect weather patterns and marine ecosystems.

Impact On Animals

Habitat Loss:
- Species losing their natural habitats due to rising temperatures and changing landscapes.
Altered Migration Patterns:
- Animals changing migration routes and timings due to temperature shifts and food availability.
Endangerment of Species:
- Increased risk of extinction for vulnerable species (e.g., polar bears, coral reefs).
Disruption of Ecosystems:
- Changes in food webs and predator-prey relationships due to shifting climate conditions.
Health Risks:
- Increased stress from temperature extremes and the spread of diseases affecting wildlife.

Causes of Climate Change

Greenhouse Gas Emissions:
- Carbon dioxide (CO2) primarily generated from the combustion of fossil fuels such as coal, oil, and natural gas.
- Methane (CH4) emissions largely arise from agricultural activities, particularly livestock production, as well as from decomposing organic matter in landfills.
- Nitrous oxide (N2O) released from various industrial processes and certain agricultural practices contributes significantly to greenhouse gas levels.
Deforestation:
- The removal of trees, which naturally absorb CO2, leads to higher concentrations of CO2 in the atmosphere, exacerbating climate change.
Industrial Processes:
- Major industries like cement, chemical manufacturing, and metallurgy emit a considerable amount of greenhouse gases during production.
Agricultural Practices:
- The use of nitrogen-based fertilizers results in nitrous oxide release, while livestock farming generates methane, both contributors to climate change.
Land Use Changes:
- Urbanization and the conversion of forests and wetlands into agricultural land can disrupt existing carbon sinks and contribute to increased atmospheric CO2.

Effects on Weather

Increased Temperatures:
- Global average temperatures are on the rise, resulting in more frequent heatwaves and altering traditional climate patterns worldwide.
Extreme Weather Events:
- A notable increase in the frequency and intensity of natural disasters, including hurricanes, floods, droughts, and storms.
Changes in Precipitation Patterns:
- Disparities in rainfall distribution, causing certain regions to experience excessive flooding while others face prolonged drought conditions.
Ocean Changes:
- Rising sea temperatures and increased ocean acidification are affecting atmospheric conditions and the health of marine ecosystems.

Impact on Animals

Habitat Loss:
- Many species are losing their natural habitats due to rising temperatures and environmental changes, resulting in diminished biodiversity.
Altered Migration Patterns:
- Animals are adjusting their migration routes and the timing of their movements in response to temperature fluctuations and changes in food availability.
Endangerment of Species:
- Particularly vulnerable species, like polar bears and certain coral reefs, face heightened extinction risks due to changing habitats and climatic conditions.
Disruption of Ecosystems:
- Ecosystem dynamics are shifting, leading to changes in food webs and predator-prey relationships as species adapt to new climate realities.
Health Risks:
- Wildlife experiences increased stress from extreme temperatures, alongside the increased spread of diseases as ecosystems shift and species interactions change.
