Forecasts: Drought/Floods/Water Supply

Climate-driven forest disturbances, particularly drought-induced tree mortality and large high-severity fires from increasingly warm and dry conditions, are altering forest ecosystems and the ecosystem services society depends on (e.g., water supplies) in the Southern Rockies and across the Western U.S. We will combine unique, long-term place-based ecological data, diverse methods (e.g., paleo...

Drought is a prolonged and widespread deficit in available water supplies that creates multiple stressors across ecosystems and communities. The U.S. Geological Survey Water Mission Area conducts drought research and modeling to improve drought prediction capabilities. The research focus is on understanding the hydrological, ecological, and economic ramifications of drought. The modeling focus...

To understand changes in our climate, USGS scientists are synthesizing long-term data sets, including geologic records that can extend over millions of years. Paleoclimatology, in particular, uses evidence of past climate change preserved in sediments, rocks, tree rings, corals, ice sheets and other climate archives to reconstruct how climates varied in the past.
