What exactly is Global warming

Global warming is basically the increase in the temperature in the atmosphere. which causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. It happens when greenhouse gases(carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth's atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. The greenhouse effect is becoming stronger as a result of human activities, which is causing the warming we have observed over the past century.
