Global warming is driven by various factors, but two major causes are:
-
Greenhouse Gas Emissions: Human activities, particularly the burning of fossil fuels (such as coal, oil, and natural gas) for energy, transportation, and industrial processes, release large amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) into the atmosphere. These gases trap heat from the sun, preventing it from escaping back into space, a phenomenon known as the greenhouse effect. Deforestation also plays a significant role, as trees absorb CO2. When forests are cleared or burned, this stored carbon is released back into the atmosphere, further increasing GHG concentrations.
-
Agricultural Practices: Agriculture contributes to global warming through methane (CH4) and nitrous oxide (N2O) emissions, both potent greenhouse gases. Methane is released during the digestion processes of ruminant animals (like cows and sheep) and from rice paddies, while nitrous oxide emissions arise from the use of synthetic fertilizers and manure management. These emissions can significantly impact the climate due to their high global warming potential, with methane being over 25 times more effective than CO2 at trapping heat over a 100-year period.
Addressing these causes involves transitioning to renewable energy sources, improving agricultural practices, and enhancing forest management to reduce emissions and increase carbon sequestration.
