Thus, if the temperature of the ocean or the surface of the land is relatively cool in a certain area, drought may occur in regions that rely on those sources of moisture.

With climate change and the modern increase in greenhouse gas emissions, the authors dont paint a happy future and instead see one that will experience many more droughts.

The scale of these impacts also varies and can be tracked at various levels (e.g., regional, national, community, and household) of agricultural production. Droughts often give rise to famines that can lead to the loss of millions of lives. This is mainly due to lesser rainfalls. The present drought in Cape Town has been caused by extremely poor rainfall in recent months, with the result that the water supplies are under enormous pressure. Failure to procure these resources, together with a severe dry spell. As hot air rises and expands, it creates a contrasting flow of air from cooler areas where air condenses and sinks. When the soil is moist, surface air temperatures stay cooler because more of the sun's energy is absorbed in the process of evaporation. The effects of drought are widespread and have devastating effects on the environment and the society as a whole. The research, published Wednesday in the journal Nature, finds that greenhouse gases generated by power plants, farming, cars, trains and human activities in general have influenced the risk of droughts. .
