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 Global Warming?

3. What is Global Warming?
• 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 GLOBAL WARMING

5. CAUSES OF GLOBAL WARMING
• 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 GLOBAL WARMING

7. EFFECTS OF GLOBAL WARMING
(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 REDUCE GLOBAL
WARMING

9. MEASURES TO REDUCE GLOBAL
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.
