Climate change drought facts

Drought and Climate Change Climate change increases the odds of worsening drought in many parts of the United States and the world in the decades ahead. Regions such as the U.S. Southwest are at particular risk. There are a number of ways climate change may contribute to drought Global climate change affects a variety of factors associated with drought. There is high confidence that increased temperatures will lead to more precipitation falling as rain rather than snow, earlier snow melt, and increased evaporation and transpiration. Thus the risk of hydrological and agricultural drought increases as temperatures rise With climate change, droughts will become more frequent and more severe. We need to plan for preventing droughts proactively by looking at how much water is needed and what kind of water resources are available under different drought conditions A drought is an extended period of deficient rainfall relative to the statistical multi-year average for a region. But because of the various ways it is measured, an objective drought definition has yet to be produced upon which everyone can agree It's because warming is altering the water cycle—hotter soils lose their moisture faster, intensifying drought conditions. But heat also leads to more evaporation from the ocean. That evaporation transfers huge amounts of energy into the atmosphere and feeds more moisture into rain and snow
