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.

Climate change refers to the long term changes in the Earth’s climate especially those caused by human activities such as burning of fossil fuels, deforestation and pollution, leading to an increase in the Earth’s average surface temperature, altered precipitation patterns, and other environmental impacts.
Climate change devastates ecosystems,causing rising sea levels (3.2mm/year), intense natural disasters (26% increase since 1980), melting glaciers (18% since 1980), and extreme weather events, displacing 22.5 million people annually with global economic losses exceeding $320 billion (2020).
Climate change causes sea levels to rise through melting glaciers, ice sheet collapse and thermal expansion, leading to coastal erosion, flooding, saltwater intrusion and loss of ecosystems. By 2100, sea levels may rise 26-82 cm, displacing 143 million people, contaminating water sources and causing $1 trillion in economic losses annually.
Climate change demands urgent action. Effective strategies include transitioning to renewable energy, carbon capture, sustainable land use and climate resilient infrastructure. International cooperation, policy reforms and public awareness are crucial. Mitigating climate change requires collective efforts, reducing emissions by 45% by 2030 and achieving net-zero by 2050 to secure a livable future.
