Study Notes
Global Warming and Climate Change
- Global warming is the long-term heating of Earth's surface due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels.
- Climate change is a long-term change in average weather patterns that define Earth's local, regional, and global climates.
- Global warming is a human-induced climate change, whereas climate change is a natural phenomenon.
Greenhouse Gas Emissions
- Carbon dioxide is the most common greenhouse gas, but other gases are more potent.
- Contributions to greenhouse gas emissions come from industry, roads, housing energy, leaks, and other irregular releases from pressurized containers in the gas and oil industry, cement, deforestation, livestock, and manure.
Habitat Shifting and Alteration
- Montane species' ranges are decreasing upwards, leading to isolation of subpopulations.
- Nature reserves' fixed positions in the landscape are affected by shifting geographical ranges.
Associated Changes
- Decline in ice coverage affects polar bears, breeding seals, and increases swimming distances.
- Reduction in foraging efficiency: one seal is equivalent to 74 snow geese, 216 snow geese eggs, or 3 million berries.
Extreme Weather Events
- Increase in ice coverage prevents narwhals from traveling due to fewer ice-free breathing holes.
- Changes in phytoplankton blooms, drought, storms, flooding, fire regimes, extreme temperatures, and hurricane intensity.
Mitigation
- Forest fires/bushfires and renewable energies like solar, wind, biomass, landfill gas, and hydroelectric power can help mitigate climate change.
- Challenges include retrofitting, social norms, and impact on house prices.
Carbon Footprint
- Carbon harvesting and mechanical trees/forests can extract and store carbon.
- Food waste contributes significantly to greenhouse gas emissions, and reducing food waste can help mitigate climate change.
Individual Actions
- Opening doors, using electronic devices, and having children all contribute to carbon emissions.
- Downsizing houses, using public transport, and reducing energy consumption can help reduce individual carbon footprints.
