Answer 1

It is important to study climate change because -

1. The earth's climate is changing faster primarily as a result of human activities.
2. The number of flash floods is increasing, especially in urban areas.
3. Due to the warming of oceans the rate of evaporation is high, which is the root cause of both flooding and droughts.
4. Due to the increase in temperature, there is melting of snow on mountains and sea level is rising.
5. Human activities, especially emissions of heat-trapping greenhouse gases from fossil fuel combustion, deforestation, and land-use changes are the primary drivers of the climate changes observed in the industrial era.
