How Does Understanding Climate Change - How Greenhouse Gases Warm the Earth Work?

The Earth stays warm because greenhouse gases act like a cozy blanket around our planet.

Imagine you're wearing a thick winter coat on a cold day, it keeps you warm by trapping the heat your body produces. Greenhouse gases do something similar, but for the whole Earth. They trap the heat from the Sun that reaches our planet, keeping us comfortable instead of freezing.

When sunlight hits the Earth, some of it goes through the atmosphere and warms the ground and oceans. Then, the Earth sends this warmth back up into the air, like when you breathe out warm air in the cold.

Greenhouse gases, such as carbon dioxide and methane, are like invisible bubbles that catch this outgoing heat and send it back down to the Earth. This process is called the greenhouse effect.

It's like having a second blanket on your bed, extra warmth makes for better sleep! Without these gases, our planet would be much colder than it is now.

But sometimes we add too many blankets, or too many greenhouse gases, and that makes the Earth warmer than it should be. That’s why scientists are studying how to keep our planet just right, like keeping a room at the perfect temperature for playing and sleeping.
