What is a climate?
Climate is the average weather and temperature of a place. Towns, cities, states, countries, biomes, and even the Earth all have their own specific climates! You can click on the pictures below to find out more.
Biome Climates
Tropical Rainforests: hot, humid, wet. These types of climates have at least 2.4 inches of rain every month!
Deserts: dry with little to no plants. Deserts get very little rain every year and the sun dries out the rain they do get very quickly! They tend to be very hot during the day and very cold at night.
City Climates
Cape Town, South Africa: The city of Cape Town has a "mediterranean climate" meaning they have dry, warm summers and mild but rainy winters. Did you know Cape Town winters are from June-August since they're in the Southern Hemisphere?
Raleigh, North Carolina, USA: Raleigh has what's called a "humid subtropical climate", meaning they have hot, humid summers and cold winters.
The Earth’s climate varies based on region, but the average temperature of the earth is about 57°F, or 14°C. In comparison, the human body’s natural temperature is around 97.9°F or 36.6°C.

Now, the Earth’s average temperature does change over time. These temperature changes take place over thousands and thousands of years, sometimes even millions! That's pretty normal. The graph above shows what the temperature has looked like over the past 140 years, which is not normal. You can see in the graph that the temperature has been going up. This means that Earth's climate is changing and slowly getting hotter. Starting in 1960, it has really been going up. We'll talk about what that means on the next page, which you can go to now!
