Drought, Fire and Extreme Weather

The Rio Grande provides drinking water for more than six million people, irrigation water for two million acres of land in the United States and Mexico, and supports riparian ecosystems that are home to endangered species like the ocelot and Rio Grande silvery minnow. Climate variability and anthropogenic activities continue to stress this already limited water resource. This project was developed

The Southwest U.S. is experiencing hotter droughts, which are contributing to more frequent, severe wildfires. These droughts also stress vegetation, which can make it more difficult for forests to recover after fire. Forest regeneration in burned areas may be limited because seeds have to travel long distances to recolonize, and when they do arrive, conditions are often unfavorably hot and dry. C

The 2017 fire season in California was highly unusual with its late seasonal timing, the areal extent it burned, and its devastation to communities. These fires were associated with extreme winds and were potentially also influenced by unusually dry conditions during several years leading up to the 2017 events. This fire season brought additional attention and emphasized the vital need for manager

On August 21, 2017, Honolulu Harbor observed the highest hourly water level since tide gauge record collection began in 1905. Throughout the course of 2017, the gauge registered an unprecedented number of high-water events. These record high sea levels were the result of a series of compounding factors: ongoing sea-level rise, seasonally-elevated high tides, and a region of warm water combining wi

Fire size, frequency, overall area burned, and severity are increasing across many vegetation types in the southwestern U.S. In many cases, large contiguous areas are burning repeatedly at high severity, triggering vegetation type conversions (VTC), where once-dominant coniferous forests fail to return to their pre-fire state, often transitioning to shrub- or grass-dominated systems. Loss of these

Climate change and the extreme weather associated with it can be a major challenge to landowners and land managers interested in the protection, restoration, recovery, and management of wetlands and wildlife habitats. The Midwest is not only experiencing an increase in average temperatures and precipitation, but also an increase in the frequency of extreme events, such as heat waves and floods. Fo

The climate in Hawai‘i is changing, and alterations in rainfall amount and distribution have implications for future vegetation cover, non-native species invasions, watershed function, and fire behavior. As novel ecosystems and climates emerge in Hawai‘i, particularly hotter and drier climates, it is critical that scientists produce locally relevant, timely and actionable science products and that
