Global warming is primarily driven by the increase in greenhouse gases in the atmosphere. The burning of fossil fuels such as coal, oil, and natural gas for electricity, heat, and transportation is a significant contributor. These activities release large amounts of carbon dioxide (CO2) and other greenhouse gases, including methane (CH4) and nitrous oxide (N2O). Industrial processes also contribute through emissions from factories, cement production, and chemical manufacturing.

Agriculture is another major contributor to global warming. Livestock farming produces methane, a potent greenhouse gas, through enteric fermentation in animals. Rice paddies, due to anaerobic conditions, emit methane as well. Additionally, the use of synthetic fertilizers in agriculture releases nitrous oxide.

Waste management practices, such as landfills, generate methane during the decomposition of organic waste. Moreover, the increase in industrial waste and improper disposal methods contribute to greenhouse gas emissions. Transportation, including cars, trucks, airplanes, and ships, relies heavily on fossil fuels, leading to substantial CO2 emissions.

These activities, collectively, intensify the greenhouse effect, trapping more heat in the Earth’s atmosphere and driving global warming.
