Describe global warming.

Global warming refers to the long-term rise in Earth’s average temperature due to the excessive accumulation of greenhouse gases (GHGs) such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). These gases trap heat from the sun in the Earth’s atmosphere, preventing it from escaping into space.

Causes of Global Warming:

  1. Burning Fossil Fuels: The use of coal, oil, and natural gas in industries, power plants, and transportation releases large amounts of CO₂ into the atmosphere.
  2. Deforestation: Trees absorb CO₂, and deforestation reduces this natural carbon sink, increasing atmospheric CO₂ levels.
  3. Agriculture: Livestock farming produces methane, a potent greenhouse gas, while fertilizers release nitrous oxide.
  4. Industrial Emissions: Factories release greenhouse gases during production processes, contributing to warming.

Effects of Global Warming:

  • Climate Change: Rising temperatures cause extreme weather events like heatwaves, storms, and droughts.
  • Glacier Melting and Rising Sea Levels: Polar ice caps and glaciers are melting, leading to coastal flooding.
  • Biodiversity Loss: Many plant and animal species struggle to adapt to rising temperatures, leading to habitat loss and extinction.
  • Health Risks: Increased heat leads to dehydration, heat strokes, and the spread of diseases like malaria and dengue.
