Study Notes
Global Warming
- Global warming is the ongoing increase in Earth's average surface temperature.
- It's primarily caused by human activities, most notably the burning of fossil fuels and deforestation.
- This releases greenhouse gases into the atmosphere, leading to climate change.
Causes of Global Warming
- Burning Fossil Fuels: Burning coal, oil, and natural gas for energy and transportation releases large amounts of carbon dioxide (COâ‚‚) into the atmosphere.
- Deforestation: Cutting down trees reduces the planet's ability to absorb COâ‚‚, increasing the concentration of greenhouse gases.
- Industrial Pollution: Factories and power plants emit various harmful gases, including COâ‚‚, that contribute to warming.
- Agricultural Practices: Livestock farming produces methane (CHâ‚„), a potent greenhouse gas. The use of synthetic fertilizers releases nitrous oxide (Nâ‚‚O).
- Waste Management: Decomposing waste in landfills releases methane (CHâ‚„).
