Why are heat domes becoming more frequent and intense globally?

Heat domes are like big, cozy blankets that trap heat and make it really hot outside. They’re becoming more common and stronger because our planet is getting warmer.

The Earth is like a pot on the stove, and we're turning up the heat by using things like cars, factories, and power plants, they all let out hot gases into the air. These gases act like a lid that keeps the heat from escaping easily.

How Heat Domes Work

Imagine you’re wearing a heavy coat on a sunny day. The sun warms your body, and the coat stops the warmth from leaving. That’s kind of what happens with heat domes, they trap the hot air near the ground, making it feel even hotter than it is.

Why They're Getting Stronger

As the Earth gets warmer over time, these blankets (heat domes) become thicker and heavier. It's like turning up the stove more and more, the pot gets hotter, and so does the air around us.

Sometimes, a heat dome can feel like being in an oven that’s turned all the way up! That’s why we’re seeing record-breaking hot days happening more often.
