Question

What is global warming?

Answer 1

Global warming :

1. The rise in the temperature of the Earth's atmosphere is called global warming.
2. This can occur due to various human activities such as the burning of fossil fuels, emission of carbon dioxide from vehicles, and deforestation.
3. A major reason is an increase in the concentration of heat-trapping gases (carbon dioxide, water vapour, methane, etc.) called greenhouse gases.
4. Global warming leads to extensive climate change and loss of habitats due to the massive melting of polar ice caps and loss of forests.
