Why is the global average temperature increasing faster than predicted?

The Earth is getting warmer faster than scientists thought because extra heat from greenhouse gases is staying trapped in our atmosphere like a blanket that gets thicker every year.

Imagine you're wearing a cozy sweater on a chilly day. That’s comfortable. But now imagine someone keeps adding more sweaters, one after another, without taking any off. Soon, you’re sweating! The Earth is like you, and the greenhouse gases are like those extra sweaters.

Why the "Extra Sweater" Effect Happens

Scientists predicted how warm it would get based on what they knew about these greenhouse gases. But they didn't know that some of them, especially carbon dioxide from burning fossil fuels, were going to hang around for much longer than expected, just like a super cozy sweater that never comes off.

Also, the Earth's oceans and forests are like helpers who used to take in extra heat or carbon. But now they're getting tired, so they can’t help as much anymore. It’s like your friend who usually takes some of your sweaters, but now they’re too busy playing tag to help!

So, more heat stays trapped, and the Earth gets warmer faster than we thought, just like you getting warmer faster with all those extra sweaters!
