Global warming
Global warming is defined as an increase in the average temperature of the earth caused by human activities that produce greenhouse gas emissions. The main causes of global warming include the burning of fossil fuels for industrialization and electricity production, as well as agricultural practices like deforestation. Effects of global warming include rising sea levels from melting ice caps, more extreme weather events, and disruption of biodiversity. Actions that can help reduce global warming include transitioning to renewable energy sources, reducing electricity usage, recycling, and planting more trees to absorb carbon dioxide.

- 2. What is GlobalWarming?
- 3. What is GlobalWarming? • Roger (2011) defines Global warming as an increase in the average temperature of the earth’s atmosphere and oceans, especially a sustained increase sufficient to cause climatic change. • Gope (2013) refers to Global warming as the effect of human activities that produces the unnatural change on the climate. • In its simplest form, it can be define as the increasing global temperature.
- 4. CAUSES OF GLOBALWARMING
- 5. CAUSES OF GLOBALWARMING • Industrialisation many factories use oil and fossil fuels to power their mechines • Coal Power plants generating electricity with coal emit greenhouse gases which trap heat in the atmosphere e.g Carbon dioxide (Kopchick, 2009) • Agricultural business (biofuels, deforestation and cattle producing methane). Trees reduce Carbon dioxide in the atmosphere
- 6. EFFECTS OF GLOBALWARMING
- 7. EFFECTS OF GLOBALWARMING (Gope, 2013) • Rising temperatures in poles, cause ice caps to melt and this result in sea level rising. • High temperatures speed up evaporation creating droughts in some areas and high rainfall in other areas. • Hurricanes and Storms • Biodiversity is disturbed. • Spread of diseases
- 8. MEASURES TO REDUCEGLOBAL WARMING
- 9. MEASURES TO REDUCEGLOBAL WARMING • Use renewable energy sources for example, solar energy, hydro electricity and wind electricity (Bussey, 2008) • Recycle bottles and plastics, reduce the usage of electricity and reuse bottles and plastics. • Plant more trees.
