Study Notes
Human Activities and Climate Change
- Global warming is the increase in Earth's average temperature caused by gases in the atmosphere trapping heat.
- The greenhouse effect is the warming caused by these gases, preventing heat from escaping into space.
- Greenhouse gases include water vapor, carbon dioxide, methane, ozone, and nitrous oxide.
- Climate change refers to a broader term encompassing changes in temperature, precipitation, and other weather patterns.
- Even small changes in average temperature (e.g., 1°C) can significantly impact climates.
- Burning fossil fuels (coal, oil, gas) is a major source of carbon dioxide emissions.
- Deforestation also contributes, as trees absorb CO2.
- Methane is a potent greenhouse gas produced by livestock, waste disposal, and agriculture.
- Nitrous oxide emissions come from fertilizers and industrial processes.
Annual Greenhouse Gas Emissions
- Industrial processes, power stations, transportation fuels, agriculture, and waste disposal are key sectors of greenhouse gas emission.
Impacts of Climate Change
- Globally: Increased temperatures lead to more severe storms (e.g., hurricanes, tornadoes), increased flooding, drought, and food security issues, and more diseases.
- Locally: Worsening air and water quality (especially in cities), extreme weather events, decline in water supply and agriculture, and sea level rise in coastal areas pose threats and increased costs for insurance in risk-prone areas.
- Indigenous peoples: Climate change impacts traditional food, water sources, lands, and cultural practices.
Global Warming
- Carbon dioxide is the major greenhouse gas from burning fossil fuels.
- In 1 year, 97 million barrels of oil were consumed globally (or 3.54 billion barrels per year).
- CO2 prevents energy from bouncing back into space.
- This effect is like a greenhouse, hence the name.
- Climate change results from the increased heat in the atmosphere.
- Reduced fossil fuel use is a way to decrease global warming.
Global Initiatives to Combat Climate Change
- Implement carbon taxes.
- Utilize renewable resources (wind, solar, tidal, geothermal, biomass).
- Improve transportation (e.g., electric vehicles, public transport).
- Use energy-efficient appliances and buildings.
- Reduce, reuse, recycle, and rethink consumption choices, including reducing meat consumption.
- Increase public awareness campaigns and actions.
