What Causes the ‘Greenhouse Effect’ and Why Does It Matter?

The greenhouse effect is like a blanket around Earth. Imagine you're wearing a cozy blanket on a cold day, it keeps you warm by trapping the heat from your body. The same thing happens with gases in our atmosphere, like carbon dioxide and methane. They trap heat from the Sun, keeping Earth warm enough for life to exist. But when we add too many of these gases, the blanket gets thicker, and the planet gets warmer, just like if you wore multiple blankets at once!

Examples

  1. A warm cup of cocoa stays hot longer when you cover it with a lid, just like the greenhouse effect keeps Earth warm.
  2. Putting on an extra sweater makes you feel warmer, that's like adding more carbon dioxide to our atmosphere.
  3. A greenhouse keeps plants warm during winter by trapping heat from the Sun, similar to how gases in the air trap heat around the planet.
