Global warming primarily happens through human activities that increase greenhouse gases in the atmosphere. The reference provided identifies some of these key activities:
Ways Human Activities Contribute to Global Warming
These activities increase the concentration of greenhouse gases, trapping more heat and leading to a rise in global temperatures.
- Burning Fossil Fuels: This includes burning coal, oil, and natural gas for energy. This releases large amounts of carbon dioxide (CO2), a major greenhouse gas, into the atmosphere.
- Deforestation (Cutting Down Forests): Forests absorb CO2 from the atmosphere. Cutting them down releases the stored carbon and reduces the Earth's capacity to remove CO2.
- Farming Livestock: Livestock, particularly cattle, produce methane (CH4), a potent greenhouse gas, as part of their digestive process.
In short, adding greenhouse gasses to the atmosphere increases the greenhouse effect which causes global warming.
