Answer 1

Global warming is a natural phenomenon. Global warming can be defined as long-term heating of the Earth’s climate system observed since the pre industrial period (between 1850 and 1900) .
It happens due to human activities like primary fossil fuel burning , which increases heat trapping greenhouse gas levels in the earth’s atmosphere which leads to melting of polar ice caps which leads to an increase in sea level .
