Climate Change Impacts

Science plays an essential role in helping communities and resource managers understand the implications of climate change, anticipate the effects of change, and prepare for projected changes. GECSC scientists conduct research critical to understanding the physical, chemical, and biological components of the Earth system, the causes and consequences of natural and anthropogenic climate change, and the vulnerability and resilience of the Earth system to such changes.

Understanding long-term drivers of vegetation change and stability in the Southern Rocky Mountains with paleoecological data and ecological models

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...

Quaternary Hydroclimate Records of Spring Ecosystems

Desert springs and wetlands are among the most biologically productive, diverse, and fragile ecosystems on Earth. They are home to thousands of rare, endemic, and endangered plants and animals and reflect the availability and health of emergent groundwater. Despite the ecological importance of these wetlands, our knowledge of how they might respond to predicted future climate change is limited...

Past Perspectives of Water in the West

In the intermountain west, seasonal precipitation extremes, combined with population growth, are creating new challenges for the management of water resources, ecosystems, and geologic hazards. This research contributes a comprehensive long-term context for a deeper understanding of past hydrologic variability, including the magnitude and frequency of drought and flood extremes and ecosystem...

Burned Area Essential Climate Variable

Essential Climate Variables (ECVs) track critical attributes of the atmosphere, oceanic, and terrestrial systems over time-scales appropriate for analyzing their relationships with climate change. As part of a larger Climate Data Record (CDR) and ECV project, scientists at GECSC are leading the development and validation of the Burned Area ECV algorithm. This algorithm automatically extracts...

Ecosystem Services Assessment and Valuation

Ecosystem services are the benefits that nature provides to human well-being: clean air and water, protection from natural disasters, fisheries, crop pollination and control of pests and disease, and outdoor places for recreation, solitude, and renewal. Ecosystem services underlie the functioning of our entire economy. They are neither worthless nor priceless, and by integrating the physical...

Exploring Future Flora, Environments, and Climates Through Simulations (EFFECTS)

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...

Geologic Records of High Sea Levels

This project studies past high sea levels on coastlines that preserve fossil coral reefs or marine terraces. We ascertain the magnitudes of sea-level high stands by field mapping, stratigraphic measurements, and precise elevation measurements. Geochronology is accomplished by radiocarbon dating of mollusks (for Holocene-to-last-glacial deposits), uranium-series dating of corals (for high-sea...

Global Ecosystems

The Earth contains an astonishing variety of terrestrial, freshwater, and marine ecosystems, which provide biological resources and services that are essential to our survival. A high resolution, data-derived, global ecosystems map will improve our ability to manage, conserve, and restore ecosystems that are increasingly threatened by fragmentation, alteration, loss, invasive species, fire...

Holocene Hydroclimate of Western North America

The objectives of this project are to reconstruct detailed histories of Holocene hydroclimate and corresponding environmental change from geological archives such as lake sediment, peat, and wood to more fully understand past, ongoing, and future change and its impacts.

Mountain Pine Beetle Impacts on Carbon Cycling

In the Southern Rocky Mountains, an epidemic outbreak of mountain pine beetle (Dendroctonus ponderosae; MPB) has caused forest mortality on a scale unprecedented in recorded history. The impacts of insect-induced mortality have only recently received attention, although other disturbances such as fires and land-use change have a strong influence on carbon sequestration and can result in a net...

Paleohydrology of Desert Wetlands

Springs and wetlands are among the most highly threatened ecosystems on Earth. Although geographically limited, they support more than 20% of all the threatened and endangered species in the United States. Scientists from the U.S. Geological Survey are examining the rock record to determine how springs and wetlands responded to abrupt climate change during prehistoric times and the recent geologic...
