Land Cover Change

The past decade encompasses some of the most extensive fire activity in recorded history. An area the size of Vermont (~24,000 km2) burned in a single Siberian fire in the summer of 2019 (Kehrwald et al., 2020 and references therein) while Australia, Indonesia and the Amazon have all experienced their most intense fires in recorded history (van Wees et al, 2021 and references therein). As more...

Land cover change is one of the fundamental measures for understanding pressures on ecosystems and is widely used to understand the consequences to biodiversity and ecosystem services. This study utilizes land cover and other associated socioeconomic and environmental data to examine the consequences of land cover change in human-dominated landscapes, and how provisioning of ecosystem services...

Drought and fire are powerful disturbance agents that can trigger rapid and lasting changes in the forests of western North America. Over the last decade, increases in fire size and severity coincided with warming, drought, and earlier snowmelt, factors that projected climatic changes are likely to exacerbate. However, recent observations are brief relative to the lifespans of trees and include...

Energy is a cornerstone issue for humanity, nations, and individuals. How we create and use energy impacts the consequences it embodies. The critical issue facing humanity involves meeting our massive and growing energy needs, without undermining human and natural capital. Facing the challenge of long-term, sustainable energy for the nation and world requires understanding the consequences of...

Climate changes can significantly affect species and ecosystems. Historical and paleoenvironmental data record species and ecosystem responses to past climate changes, but these records become sparse as one goes further back in time. Model simulations can be used fill the spatial and temporal gaps in observed records to improve our understanding of the potential magnitude, rate, and spatial...

Large wildfires have raged across the western Americas in the past decade including the Las Conchas, New Mexico fire that burned 44,000 acres in a single day in 2011 (Orem and Pelletier, 2015, Geomorphology 232: 224-238, and references therein), the 2016 Fort McMurray, Alberta fire that required evacuating an entire city, and the 2015 Alaskan fire season that burned more than 5 million acres...
