Historic 2013 Colorado Front Range storm accomplished up to 1,000 years of erosion,CU-Boulder study finds
2013 Colorado storm accomplished 1,000 years of erosion CU-Boulder
2015/9/8
The historic September 2013 storm that triggered widespread flooding across Colorado’s Front Range eroded the equivalent of hundreds, or even as much as 1,000 years worth of accumulated sediment from ...

Warming Western U.S. Driest Period 1,000 Years
2015/3/4
During the second half of the 21st century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions “driven pri...
Stable isotope records for the last 10 000 years from Okshola cave (Fauske, northern Norway) and regional comparisons
Stable isotope last 10 000 years Okshola cave

The sensitivity of terrestrial environments to past changes in heat transport is expected to be manifested in Holocene climate proxy records on millennial to seasonal timescales. Stalagmite formation...
Rapid climatic variability in the west Mediterranean during the last 25 000 years from high resolution pollen data
climatic variability High-temporal resolution pollen west Mediterranean
2009/12/3
High-temporal resolution pollen record from the Alboran Sea ODP Site 976, pollen-based quantitative climate reconstruction and biomisation show that changes of Mediterranean vegetation have been clear...
Millennial-scale climatic variability between 340 000 and 270 000 years ago in SW Europe：evidence from a NW Iberian margin pollen sequence
climatic variability Marine Isotope Stage SW Europe
2009/12/3
We present a new high-resolution marine pollen record from NW Iberian margin sediments (core MD03-2697) covering the interval between 340 000 and 270 000 years ago, a time period centred on Marine I...
Comparing transient, accelerated, and equilibrium simulations of the last 30 000 years with the GENIE-1 model
GENIE-1 model
2008/11/11
We examine several aspects of the ocean-atmosphere system over the last 30 000 years, by carrying out simulations with prescribed ice sheets, atmospheric CO2 concentration, and orbital parameters.
Simulating low frequency changes in atmospheric CO2 during the last 740 000 years
low frequency changes atmospheric CO2
2008/11/11
Atmospheric CO2 measured in Antarctic ice cores shows a natural variability of 80 to 100 ppmv during the last four glacial cycles and variations of approximately 60 ppmv in the two cycles between 410 ...

“EDML1”：a chronology for the EPICA deep ice core from Dronning Maud Land, Antarctica, over the last 150 000 years
EPICA Dronning Maud Land Antarctica
2008/11/5
A chronology called EDML1 has been developed for the EPICA ice core from Dronning Maud Land (EDML). EDML1 is closely interlinked with EDC3, the new chronology for the EPICA ice core from Dome-C (EDC) ...
Modeling variations of marine reservoir ages during the last 45 000 years
marine reservoir ages modeling variations
2008/10/30
When dating marine samples with 14C, the reservoir-age effect is usually assumed to be constant, although atmospheric 14C production rate and ocean circulation changes cause temporal and spatial rese...

Eurasian ice sheet East Asian summer monsoon interglacial
2008/10/30
Deep-sea and ice-core records show that interglacial periods were overall less "warm" before about 420 000 years ago than after, with relatively higher ice volume and lower greenhouse gases concentrat...
