Costa Rica is famous for its beautiful cloud forests. These are forests that sit high up in the mountains. They are almost always covered in a thick, cool mist. This mist is basically a cloud that stays right on the ground. It gives the plants and animals the water they need to survive.

But things are changing. The air is getting warmer. Because of this, the clouds are starting to hang higher up in the sky. They are moving away from the trees.

When the clouds leave, the forest loses its main source of water. The mosses, ferns, and orchids that live on the tree branches are starting to dry out.

This is a big problem for the animals, too. Many frogs and birds that live in these forests are used to the constant damp, cool air. As the forest gets drier and warmer, these animals struggle to find a place to live.

Scientists have been watching this for a while. They say the forest is turning into something different. It is losing the special mix of wet, cool weather that made it a cloud forest in the first place.

Experts are worried that if the planet keeps getting warmer, these amazing forests might disappear forever. It is a sign of how much a small change in temperature can hurt nature.
