The Colorado River provides water to 40 million people in the southwestern United States. Consistent water level declines in Colorado River Basin reservoirs have focused research attention on the long-term changes in winter precipitation and the timing of snowmelt and runoff. Research on how warming temperatures affect winter precipitation and spring snowmelt is ongoing, however, less attention ha

Wildfire is a natural and essential process in forest ecosystems, but characteristics of fire regimes that have shaped these landscapes over long time scales are changing with climate change and human activities. In some places, changes in fire size, frequency, and severity threaten to degrade essential ecosystem services that produce clean air and water, fertile soil for crop and wood production,

Millions of acres of California’s forest cover have been lost due to severe wildfire and drought mediatedinsect outbreaks. These acres may not grow back as forests without management action, which could negatively impact carbon sequestration, access to clean drinking water, wildlife habitat and recreation opportunities. Various factors, including limited regeneration potential, hotter and more ext

The quantity and availability of weather- and climate-related data has grown dramatically over the past decade due in part to improvements in computing speed, internet bandwidth and data visualization tools. Ideally, these improvements should help information reach experts in the relevant domain and inform decision making, leading to better weather- and climate-related decision-making and risk man

Fire has always been a part of life in southern California. Climate change and current fire management practices have led to catastrophic losses and impacts to human health, infrastructure and ecosystems, as seen, for example, in the 2018 Montecito debris flow. Indigenous wisdom instructs that rather than suppressing fire, we should seek to be in good relationship with fire. This project centers t

The complex challenge of adapting to climate changerequires collaborative solutions that can be enhanced by connecting individuals to each other and to essential information. This project will evaluate the effectiveness of online decision information tools designed to aid adaptation, that are supported by the development of a network of practice. Networks can aid adaptation by improving the quanti

Stream flow is directly tied to climate, and numerous studies provide substantial evidence that climate change is a threat to future aquatic water flow processes. In the southwestern United States, mountain snow is a primary water source for streams and rivers. However, climate change is threatening the region's mountain snow, leading to reduced snowpack, earlier snowmelt, and more precipitation f

Climate Change is making our environment unpredictable. Increased persistence of drought is causing deaths of plants and animals across our landscapes. However, drought amongst the western United States is not a new thing. Native American populations have been living with drought since time immemorial and practiced culturally prescribed fire practices to foster the landscape for an environment tha

The Southwest Fire Climate Adaptation Partnership (SW FireCAP) is working to advance fire and climate adaptation in the southwestern U.S. Focused on cross-organizational collaboration and leveraging resources, the partnership facilitates climate adaptation planning by “sharing Indigenous and Western knowledge perspectives, being inclusive, and building trust.” The Collaborative Conservation and Ad

Indigenous knowledge systems, such as traditional ecological knowledge, contain climate observations and adaptation strategies reaching back millennia. These include methods for caring for our natural resources and relations, such as through drought resilient agriculture, soil, and water management practices. Despite a growing global recognition among researchers and resource managers of the value

Increasing wildfire activity in the western US poses profound risks for human communities and ecological systems. Recent fire years are characterized not only by expanding area burned but also explosive fire growth. In 2020, several fires grew by >100,000 acres within a 24-hour period. Extreme single-day fire spread events such as these are poorly understood but disproportionately responsible for
