Answer 2

Answer:

Global warming is defined as an increase in the average temperature of the Earth’s surface.  

Causes of global warming:

• Global warming occurs as a result of the increased concentration of greenhouse gases in the atmosphere.
• Greenhouse gases include carbon dioxide, methane, and water vapour.
• These gases trap solar radiations released back by the Earth.
• This helps in keeping our planet warm and thus, helps in human survival.
• However, an increase in the amount of greenhouse gases can lead to an excessive increase in the Earth’s temperature, leading to global warming.
• Global warming is a result of industrialization, burning of fossil fuels, and deforestation.
