The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
Drought can occur anywhere in the world and harm people and ecosystems. Drought is becoming more frequent and more severe due to climate change.
