Climate Matters is a reporting resource program that helps meteorologists and journalists report on climate impacts and solutions in ways that are local, immediate, and personal grounded in the latest science. Even if the overall water supply is low, drought is usually less of a concern in the winter months because demand is far less than in the summer. Scientists gather paleoclimatic data fromtree rings,sediments found in lakes and oceans,ice cores, and archaeologicalfeatures andartifacts. According to this analysis, based on the impacts of extreme weather events and the socio-economic losses they cause, Japan, the Philippines and Germany are the most affected places by climate change today. When the demand for water is high during a period of low rainfall, when the rivers and groundwater are not re-charged as usual, the impacts can be worse. Precipitation is the result of the natural process in which: The process is driven by the heat of the sun; the hotter it is, the greater the rate of evaporation.

In the early 1970s, more than 100,000 people died and millions of people were forced to migrate. Risk(or more specifically, disaster risk) is the potential disaster losses (in terms of lives, health status, livelihoods, assets and services) which could occur to a particular community or a society over some specified future time period. In this study, researchers found that states ranking highest in overall vulnerability often had less to do with how frequently drought occurs, and more with how prepared the state is for drought impacts. For general inquiries, please use our contact form. The cooler waters affect storm patterns by contributing to drier-than-normal conditions in parts of North and South America. Sometimes how much water humans consume, and the timing of that consumption, factors into how much water is available at a later date for people, plants and animals. Really hot temperatures can make a drought worse by evaporating moisture from the soil. National Geographic Society is a 501 (c)(3) organization. The NASA Earth Observatory lists three factors that cause drought. Protected areas, areas of ecological value, and stressed watersheds are considered vulnerable. In the 1950s, severe drought returned to the Great Plains and southwestern United States, affecting half of the continental U.S. Low rainfall and high temperatures caused the production of crops in some areas to drop nearly 50 percent. The animals are all mainly grassland and desert types adapted to hot, dry weather. It also maintains a register of drought, hazard and water plans by state, accompanied by local drought experts and agencies. It is not meant to be used as a drought predictor or for detailed information about specific areas.
