Paleoclimate simulations for North America over the past 21,000 years: Features of the simulated climate and comparisons with paleoenvironmental data Paleoclimate simulations for North America over the past 21,000 years: Features of the simulated climate and comparisons with paleoenvironmental data
Maps of upper-level and surface winds and of surface temperature and precipitation illustrate the results of a sequence of global paleoclimatic simulations spanning the past 21,000 yr for North America. We review (a) the large-scale features of circulation, temperature, and precipitation that appear in the simulations from the NCAR Community Climate Model Version 1 (CCM 1), (b) the...

Pliocene and early Pleistocene environments and climates of the western Snake River Plain, Idaho Pliocene and early Pleistocene environments and climates of the western Snake River Plain, Idaho
Sedimentological, palynological, and magnetic susceptibility data provide paleoenvironmental and paleoclimatic information from a 989 ft (301 m) core of sediments from the upper Glenns Ferry and Bruneau Formations from near the town of Bruneau in Owyhee County, Idaho. Chronology is based on stratigraphic position, paleomagnetism, and biostratigraphic data, which collectively suggest a...

Middle Pliocene vegetation: Reconstructions, paleoclimatic inferences, and boundary conditions for climate modeling Middle Pliocene vegetation: Reconstructions, paleoclimatic inferences, and boundary conditions for climate modeling
The general characteristics of global vegetation during the middle Pliocene warm period can be reconstructed from fossil pollen and plant megafossil data. The largest differences between Pliocene vegetation and that of today occurred at high latitudes in both hemispheres, where warming was pronounced relative to today. In the Northern Hemisphere coniferous forests lived in the modern...

Joint investigations of the Middle Pliocene climate I: PRISM paleoenvironmental reconstructions Joint investigations of the Middle Pliocene climate I: PRISM paleoenvironmental reconstructions
The Pliocene epoch represents an important transition from a climate regime with high-frequency, low-amplitude oscillations when the Northern Hemisphere lacked substantial ice sheets, to the typical high-frequency, high-amplitude Middle to Late Pleistocene regime characterized by glacial—interglacial cycles that involve waxing and waning of major Northern Hemisphere ice sheets. Analysis...

PRISM 8 degrees X 10 degrees North Hemisphere paleoclimate reconstruction; digital data PRISM 8 degrees X 10 degrees North Hemisphere paleoclimate reconstruction; digital data
The PRISM 8?x10? data set represents several years of investigation by PRISM (Pliocene Research, Interpretation, and Synoptic Mapping) Project members. One of the goals of PRISM is to produce time-slice reconstructions of intervals of warmer than modern climate within the Pliocene Epoch. The first of these was chosen to be at 3.0 Ma (time scale of Berggren et al., 1985) and is published...

A joint US-USSR workshop met at the Laboratory of Paleogeography of the Academy of Sciences of the USSR in Moscow from April 20th to 23rd, 1990 to discuss Pliocene paleoclimates and to develop a joint long- term research program. Soviet participants included more than fifteen scientists from across the USSR, and the United States was represented by four scientists from the U.S...
