Latest Drought Stories
County-by-county report identifies socially vulnerable communities in 13 states facing risk of drought, flooding, hurricanes and sea-level rise WASHINGTON, Oct.
On Tuesday the UN sent out an alert that East Africa could be hit by flash floods in approaching months, with the potential to affect hundreds of thousands of people already suffering from a severe drought.
A 2005-2007 dry spell in the southeastern United States destroyed billions of dollars of crops, drained municipal reservoirs and sparked legal wars among a half-dozen statesâ€”but the havoc came not from exceptional dryness but booming population and bad planning, says a new study.
A Texas A&M University professor says much of Texas is suffering severe drought, with some areas experiencing once-in-a-century dry weather conditions. Professor John Nielsen-Gammon, who is also Texas' state climatologist, says areas near San Antonio, Victoria and Corpus Christi are reporting record-breaking drought. According to the National Weather Service, the past 22 months have been among the driest ever for San Antonio, he said.
Researchers say baldcypress trees in central Texas provide a record of past weather and clues to the region's future. Malcolm Cleaveland of the University of Arkansas and his team have been taking cores from the trees that show the rings, the Austin American-Statesman reported Tuesday.
A new study by researchers from the Nairobi-based International Livestock Research Institute (ILRI) and the United Kingdom's Waen Associates has found that by 2050, hotter conditions, coupled with shifting rainfall patterns, could make anywhere from 500,000 to one million square kilometers of marginal African farmland no longer able to support even a subsistence level of food crops.
Climate change can have devastating effects on endangered species, but new mathematical models may be able to aid conservation of a population of bighorn sheep.
Scientists say they're studying bighorn sheep on an island off the coast of Mexico to determine the effects of climate change on endangered species. The sheep, brought to Tiburon Island in 1975, are not at risk from disease or predators, said Barry Brook, a researcher with Faculty of 1000, a London-based cooperative of international scientists. Climate change is the only variable threat to the sheep, making them good subjects for a mathematical model aimed at predicting the effects of such...
Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...
