Question
Discuss the role of greenhouse gases in causing global warming. Write the effects of global warming.
Answer
Greenhouse gases are gases in the atmosphere that trap heat radiated from the Earth’s surface, resulting in an increase in the Earth’s temperature. Carbon dioxide, methane, water vapor, and nitrous oxide are some of the major greenhouse gases.
The effects of global warming are numerous and include:
- Rising global temperatures: The average global temperature has increased by about 1°C since the pre-industrial era, and this increase is projected to continue.
- Melting of polar ice caps: The melting of polar ice caps has led to rising sea levels, which could cause flooding and displacement of coastal populations.
- Extreme weather events: Global warming has led to an increase in extreme weather events such as heatwaves, droughts, and heavy rainfall.
