The phenomenon of climate change is not new but it has accelerated due to human needs and development. While the course of climate change has been the result of the Industrial Revolution over several decades. Natural processes such as changes in the Sun’s energy and volcanic eruptions also affect the Earth’s climate.

Here are the main reasons for climate change in recent times:

1. Greenhouse Gas Emissions: The burning of fossil fuels emits large amount of GHGs such as Carbon-dioxide(CO2), methane (CH4), nitrous oxide (N2O), CFCs and HFCs. These GHGs emissions caused Earth’s temperature to rise and subsequently lead to global warming.

2. Deforestation: Clearing forests for urban development, agriculture and logging reduces the number of trees that can absorb CO2, thus increasing carbon footprint.

3. Rapid Industrialization: Since Industrial Revolution, human activities have contributed enormously to concentration of GHGs through manufacturing processes and energy production for making goods.

4. Urbanization: The rapid growth of urban cities has often lead to increased energy consumption and emissions from vehicles, heating and cooling systems.

These human- induced factors have hastened the rate of climate change leading to warming of Earth’s surface. Collective efforts are required from governments and individual to reduce the global increase in GHGs.
