Climate Zones of the World

In some places, I make the air warm and damp, perfect for colorful parrots to fly through lush, green trees. In others, I spread a thick, white blanket of snow and make your breath look like a little cloud. I can be dry and sandy, where camels walk for miles under a bright sun, or cool and breezy, where fluffy sheep graze on grassy hills. I am the reason you wear shorts and a t-shirt in the summer and a thick coat and fuzzy hat in the winter. Hello. I am the world’s Climate Zones, and I am like a giant, invisible quilt that gives every part of the planet its own special weather. I decide if a place will have hot summers, cold winters, lots of rain, or very little at all, making each corner of the world unique.

A very long time ago, around the 5th century BCE, clever thinkers in Ancient Greece first started to notice me. They didn't have airplanes or satellites, but they realized that the sun felt different depending on how far north or south you traveled. They imagined the world had just a few big stripes of weather. They pictured a very hot one in the middle, two freezing cold ones at the very top and bottom, and two 'just right' ones in between where they lived. For hundreds and hundreds of years, people thought my quilt was that simple. But starting in the 1400s, brave explorers began sailing their ships to new lands. They saw that the hot stripe wasn't just empty and hot; it was filled with amazing rainforests and animals they had never seen before. They learned my patches were much more detailed and interesting than they first thought. It wasn't until 1884 that a scientist named Wladimir Köppen used numbers about temperature and rain to create a real map of all my different patches. He was like a detective, gathering clues to figure me out. His map was so good and so helpful that people still use it today to understand me.

Today, I help you understand so much about our amazing world. Because of me, you know that polar bears are built for my cold, icy zones at the top of the world, while monkeys love to swing through the trees in my warm, tropical zones near the middle. I help farmers decide what kinds of foods to grow, like juicy oranges in sunny places and crunchy apples in cooler ones. I also help people know how to build houses that will be cozy and warm in the snow or nice and cool in the heat. I show how every part of our planet is special but also connected, like different squares on the same quilt. By understanding my different zones, you can better understand and care for our wonderful Earth, from its driest deserts to its wettest rainforests.
