Study Notes
Climate Change
Global Warming
- Definition: Global warming refers to the long-term trend of rising average global temperatures, primarily caused by human activities that release greenhouse gases into the atmosphere.
- Causes:
- Burning of fossil fuels (coal, oil, and gas) for energy
- Deforestation and land-use changes
- Agriculture and livestock production
- Effects:
- Rising sea levels
- Increased frequency and severity of extreme weather events (heatwaves, droughts, floods)
- Changes in precipitation patterns
- Loss of biodiversity and ecosystem disruption
Greenhouse Gases
- Definition: Greenhouse gases are gases in the atmosphere that absorb and emit radiation, trapping heat and contributing to the greenhouse effect.
- Main Greenhouse Gases:
- Carbon dioxide (CO2): most abundant, primarily from fossil fuel burning and land-use changes
- Methane (CH4): from agriculture, natural gas production, and landfills
- Nitrous oxide (N2O): from agriculture, industrial processes, and natural sources
- Water vapor (H2O): most abundant, but concentration varies
- Ozone (O3): created in the stratosphere through UV radiation
- Fluorinated gases (F-gases): from industrial processes, refrigeration, and air conditioning
- Effects:
- Trap heat in the atmosphere, leading to global warming
- Enhance the natural greenhouse effect, amplifying climate change
- Influence climate patterns and weather extremes
Note: These notes focus on the core concepts and key facts related to global warming and greenhouse gases. They are meant to provide a concise and informative overview of these topics within the context of climate change.
