A major cause of global warming is the increase in greenhouse gas emissions, particularly carbon dioxide (CO2) and methane (CH4). These gases trap heat in the Earth's atmosphere, leading to a rise in global temperatures. The primary sources of these emissions include:
1. **Fossil Fuel Combustion**: Burning coal, oil, and natural gas for energy, transportation, and industrial processes releases significant amounts of CO2.
2. **Deforestation**: Trees absorb CO2, so when forests are cut down for agriculture or urban development, not only is this carbon storage lost, but the act of clearing and burning trees releases stored carbon.
3. **Agriculture**: Agricultural practices, especially livestock farming, produce methane emissions from enteric fermentation in animals and manure management.
4. **Land Use Changes**: Alterations in land use, such as converting natural landscapes to urban or agricultural areas, can significantly affect the carbon cycle.
These activities have resulted in a higher concentration of greenhouse gases in the atmosphere, which is the primary driver of climate change and global warming.
