Global warming is primarily caused by the emission of **greenhouse gases** into the atmosphere. These gases trap heat from the Sun within the Earth’s atmosphere, leading to a gradual increase in global temperatures. The main greenhouse gases responsible for global warming include:
1. Carbon dioxide (CO2): Released primarily from the burning of fossil fuels (coal, oil, and natural gas) for energy, transportation, and industrial processes. Deforestation and land-use changes also contribute to CO2 emissions.
2. Methane (CH4): Produced from agricultural activities (livestock digestion and rice paddies), landfills, natural gas production and distribution, and biomass burning.
3. Nitrous oxide (N2O): Released from agricultural and industrial activities, including the use of synthetic fertilizers, fossil fuel combustion, and biomass burning.
4. Fluorinated gases: Include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are synthetic gases used in various industrial applications such as refrigeration, air conditioning, and electronics manufacturing.
These greenhouse gases accumulate in the atmosphere and enhance the natural greenhouse effect, causing an imbalance where more heat is trapped than is radiated back into space. This leads to global warming, which has various impacts on climate patterns, sea levels, ecosystems, and human societies.
Reducing greenhouse gas emissions through mitigation strategies such as transitioning to renewable energy sources, improving energy efficiency, and adopting sustainable land-use practices is crucial for addressing global warming and its associated impacts.
