DENDROLOGY

Detailed explanation-1: -Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth’s atmosphere to trap more and more heat. This causes Earth to warm up.

Detailed explanation-2: -Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth. This heats up the atmosphere and raises the planet’s average temperature.

Detailed explanation-3: -Greenhouse gases act similarly to the glass in a greenhouse: they absorb the sun’s heat that radiates from the Earth’s surface, trap it in the atmosphere and prevent it from escaping into space. The greenhouse effect keeps the Earth’s temperature warmer than it would otherwise be, supporting life on Earth.
