Quantitative paleoclimatic reconstructions from late Pleistocene plant macrofossils of the Yucca Mountain region Quantitative paleoclimatic reconstructions from late Pleistocene plant macrofossils of the Yucca Mountain region
Plant macrofossil assemblages recovered from packrat (Neotoma) middens of late Pleistocene age from the present-day Mojave Desert of southern Nevada contain plant species that today live at higher elevations and/or farther north than the midden collection sites. Previous reconstructions of late Pleistocene climates from packrat midden assemblages in this region (Spaulding, 1985) assessed...

Atlas of relations between climatic parameters and distributions of important trees and shrubs in North America Atlas of relations between climatic parameters and distributions of important trees and shrubs in North America
This atlas explores the continental-scale relations between the geographic ranges of woody plant species and climate in North America. A 25-km equal-area grid of modern climatic and bioclimatic parameters was constructed from instrumental weather records. The geographic distributions of selected tree and shrub species were digitized, and the presence or absence of each species was...

Conditions for bubble elongation in cold ice-sheet ice Conditions for bubble elongation in cold ice-sheet ice
Highly elongated bubbles are sometimes observed in ice-sheet ice. Elongation is favored by rapid ice deformation, and opposed by diffusive processes. We use simple models to show that vapor transport dominates diffusion except possibly very close to the melting point, and that latent-heat effects are insignificant. Elongation is favored by larger bubbles at pore close-off, but is nearly

A strategy for assessing potential future changes in climate, hydrology, and vegetation in the Western United States A strategy for assessing potential future changes in climate, hydrology, and vegetation in the Western United States
Historical and geological data indicate that significant changes can occur in the Earth's climate on time scales ranging from years to millennia. In addition to natural climatic change, climatic changes may occur in the near future due to increased concentrations of carbon dioxide and other trace gases in the atmosphere that are the result of human activities. International research...
