The Powerhouse of USGS Paleo-research
The USGS is home to one of the largest, most multidisciplinary groups of scientists who unravel mysteries of the past, and help project future patterns, by studying paleoclimate.

Pollen records, postglacial: Southeastern North America
Pollen records from the unglaciated southeastern region of North America provide an overview of biogeographic changes associated with vegetational migration northward following the retreat of the Laurentide Ice Sheet. Changing insolation during the Holocene affected forest composition on the Coastal Plain, and rising sea level controlled the distribution of marsh and forested wetlands...
Chronology and Paleoenvironment of the Tunga Formation, a new lowermost Miocene sequence in the East Pisco Basin of southern Peru
The East Pisco Basin, occupying the coastal plain of Peru between 13°S and 16°S, is widely known for its extensive Eocene to Quaternary biosiliceous deposits and excellent preservation of fossil marine vertebrates. Biochronologic studies published over the past 35 years record a hiatus of about 13 million years (*32–19 Ma) separating the youngest Paleogene deposits (Otuma Formation) from...
An integrative paradigm for building causal knowledge
A core aspiration of the ecological sciences is to determine how systems work, which implies the challenge of developing a causal understanding. Causal inference has long been approached from a statistical perspective, which can be limited and restrictive for a variety of reasons. Ecologists and other natural scientists have historically pursued mechanistic knowledge as an alternative...

Impacts of changing climate and disturbance regimes on forest ecosystem resilience in the Southern Rocky Mountains
Climate-driven forest disturbances, particularly drought-induced tree mortality and large high-severity fires from increasingly warm and dry conditions, are altering forest ecosystems and the ecosystem services society depends on (e.g., water supplies) in the Southern Rockies and across the Western U.S. We will combine unique, long-term place-based ecological data, diverse methods (e.g., paleo...
Glaciers and Climate Project
Mountain glaciers are dynamic reservoirs of frozen water closely coupled to ecosystems and climate. Glacier change in North America has major socioeconomic impacts, including global sea level change, tourism disruption, natural hazard risk, fishery effects, and water resource alteration. Understanding and quantifying precise connections between glaciers and climate is critical to decision makers...
Paleoclimate Research: Integrating Systems and Models (PRISM5)
PRISM5 addresses how the world, and particularly the US east coast, is affected by climate change. We study past warm climates from the Pliocene, Middle Miocene and early Eocene because these periods provide a suite of natural climate experiments in which marine ecosystems responded to rapidly changing temperature, sea-level and atmospheric CO2 for comparison to modern and future climate change...
