Causes of Drought

Natural droughts have affected humanity at various times throughout history.

Until recently, droughts that occur naturally were frequently caused by cyclical weather patterns, such as the temperature and moisture content of the air, land, and sea.

The way air moves through the atmosphere can also have an impact on where rain falls around the earth.

Air circulation patterns change when there is an imbalance in surface temperatures, especially over the ocean.

imbalance in the supply and demand of water.

More water is needed to support both the human race and agricultural operations as the world's population continues to grow and intensive agriculture methods are used.

In order for clouds to form and rain to fall, which returns the moisture to the earth, trees and plants must release moisture into the atmosphere.

Sadly, the destruction of these natural riches is something that the human race excels at.

The earth is warming at alarming rates, which leads to droughts.

Human activities, such as the release of greenhouse gases that have a trapping effect and raise global temperatures, is primarily to blame for global warming.

Increased temperatures have the effect of making dry areas drier and wet areas wetter. Warmer temperatures cause water to evaporate more quickly in more arid locations, while they cause warmer air to absorb more moisture, resulting in greater rain showers.
