What is Atmospheric CO₂?

Atmospheric CO₂ is like a invisible blanket around Earth that helps keep it warm.

Imagine you're wearing a cozy sweater on a chilly day, that’s how CO₂ works for the planet. It traps some of the heat from the Sun, so Earth doesn’t get too cold at night or too hot during the day.

CO₂ stands for carbon dioxide. You can think of it like the breath you take after running around, your body makes more CO₂, just like cars and factories do when they use fuel. Every time a car zooms past, or a factory hums to life, it releases some CO₂ into the air.

Once CO₂ is in the air, it stays there for a long time, like how your favorite candy stays in your pocket until you eat it. Trees and oceans help take some of it away, but not all of it goes back. That means more CO₂ stays around Earth, making the blanket thicker and warmer over time.

So, every time we use energy from cars or power plants, we're adding to that invisible blanket, and that’s why scientists are watching it closely!
