Global Change and Extreme Hydrology

As climate change warms the atmosphere, Earth’s hydrology is shifting—with the potential to make floods and droughts more extreme. There is now a pressing need for decision-makers to better understand the ongoing changes in hydrologic extremes in order to make preparations for changing conditions. This report assesses changes in the frequency and severity of floods and droughts, abilities of communities to understand and forecast these changes, and strategies for better communicating the science to water resources practitioners
