Why is extreme heat becoming more common globally?

The Earth is getting hotter because we're adding more heat to it, like leaving a kitchen stove on all day.

Imagine you have a cozy blanket that keeps your house warm, that's the Earth’s atmosphere, and some parts of it act like a heat trap. These parts are called greenhouse gases, and they help keep things just right for us to live comfortably.

But now, we're using more cars, burning more coal, and cutting down trees, all of these actions make more greenhouse gases, which means the blanket gets thicker. The thicker the blanket, the hotter it gets inside. That’s why we’re seeing extreme heat more often, like when you leave your room in the sun with the windows closed, and everything feels like a sauna.

Think of it like this: your body sweats to cool down. But if the air is already hot, your sweat can’t evaporate as fast, so you feel even hotter. The Earth is doing something similar, it's working hard to stay cool, but we’re making it harder by adding more heat.

So, every time we add more heat-trapping gases, we're like kids who keep turning up the heater in a room that’s already too warm, and now, the heat just keeps coming!
