Simply, Gases that trap heat in the air are called greenhouse gases. When the sun’s rays are travelling through the Earth’s atmosphere, these gases amplify the effect of the sun’s heat. More gases in the atmosphere mean a thicker blanket around the globe, which traps more heat.

There Are Four Greenhouse Gases:

1. Water vapour
2. Carbon dioxide
3. Methane
4. Nitrous oxide

Do We Need Ghgs?

Greenhouse gases play an important part in keeping the planet warm. They cover the planet like a blanket and trap some of the sun’s hot rays, keeping our planet from becoming too cold. If it weren’t for GHGs, our planet would be 33 degrees Celsius colder than it is now!

So, when are they bad for us?

When they make climate change worse. More greenhouse gases mean a thicker blanket around the Earth, which traps more heat and raises the temperature of the Earth.
