anomalies was produced by combining (and homogenizing) model-reconstructed and RUSLE data, thus providing a range of natural variability in climate erosivity to detect the main changes from 1580 to 2004. The so-called Little Ice Age was identified
This paper deals with the potential of written historical documents to reconstruct yearly erosive rain anomalies (differences between erosivity values and long-term average) from precipitation amounts and weather anomalies. A detailed analysis
was undertaken of the Calore River Basin (South Italy) erosive rainfall using data from 425-year-long series of both observations (1922-2004) and proxy-based reconstructions (1580-1921). Annual erosivity was computed for the observational time based
as the stormiest period. Important historical climate fluctuations were observed, but with a relevant smoothing in the last 150 years of the series.

Reconstructing extreme flows using an airflow index-based stochastic weather generator and a hydrological simulation model

This paper offers an alternative to the use of geomorphological and sedimentological evidence for the reconstruction of flood and low flow frequencies. It is based on a technique developed to estimate the hydrological impact of future climate change
and it uses either observed or calculated meteorological parameters. The method is illustrated here in a reconstruction of daily flow series for the River Wye catchment above Rhayader, mid-Wales, for the period 1889-1998. The method makes use of observed
climatic variables for the entire period, with the aim of capturing actual climate variability occurring over the 110-year period.

Last Glacial snowlines in the Tibetan Plateau : an argument against an extensive coalescing icesheet

This paper focuses on the Last Glacial snowline reconstruction and uses the reconstructed snowline to argue against the claimed coalescing icesheet, with hope that the plateau's role affecting the global climates and Asian monsoons will be more
reasonably projected in modeling the Last Glacial global climates.

Dendroclimatic reconstruction of april-may temperature fluctuations in the western Himalaya of India since A.D. 1698

The AA. present the reconstruction of mean April-May temperature variations back to A.D. 1698 using ring-width chronologies of Himalayan cedar, Himalayan pine, and Himalayan spruce from the western Himalaya. The most striking feature of the present
reconstruction is the absence of any warming trend in the 20th century. Relationships between the mean April-May temperature for the western Himalayan region, Indian summer monsoon rainfall, and Southern Oscillation Index indicate that the tree-ring chronologies
, as surrogate temperature records, will provide valuable data for climate change studies with regional and global perspectives.

A 12,500-yr pollen record from Loon Lake, Wyoming provides information on the climate history of the southwestern margin of Yellowstone National Park. The environmental reconstruction was used to evaluate hypotheses that address spatial variations

Late Quaternary environmental and climatic changes in Central Brazil

Late Quaternary environmental and climatic changes in Central Brazil

Paleoenvironmental changes dating back to 30,000 yr B.P. documented in a pollen record from central Brazil (lat. 19o S) permit the reconstruction of climatic changes related to shifts of the Antarctic polar fronts. The paleoclimatic inferences were
obtained by a study of modern vegetation and pollen distribution, taking into account present-day climatic parameters.

West African paleoclimates during the last climatic cycle inferred from an Atlantic deep-sea pollen record

West African paleoclimates during the last climatic cycle inferred from an Atlantic deep-sea pollen record
The main results of pollen and dinocyst analyses on the upper 6 m of core V22-196, corresponding to the last 140,000 yr, are presented with the aim of discussing reconstructions of north tropical African environments and climates during the latest
climatic cycle, and comparing the results with previous paleoatmospheric circulation reconstructions inferred from the marine or terrestrial component of ocean sediments.

Responses of floods to Holocene climatic change in the Upper Mississippi Valley

Responses of floods to Holocene climatic change in the Upper Mississippi Valley
Valley watersheds of southwestern Wisconsin. The reconstructed record of floods shows relatively large and persistent (nonrandom) departures from contemporary long-term average flood magnitudes. The flood history indicates climatic changes
Dimensions of Holocene relict channels and sedimentological characteristics of point bars associated with these relict channels were used to reconstruct a Holocene history of long-term changes in magnitudes of 1.58 yr floods in Upper Mississippi
that are broadly similar to climatic changes indicated from fossil pollen in the same region.

Climatic reconstruction in Europe for 18,000 yr B.P. from pollen data

Climatic reconstruction in Europe for 18,000 yr B.P. from pollen data
This paper proposes a new method of reconstructing past climate from pollen data, which is applicable to other continents as well as Europe. In order to deal with the lack of perfect analogs of fossil assemblages, the AA. used a combination
of pollen types grouped according to plant phenology and present climate constraints rather than pollen percentages for each individual taxon. The distribution of pollen taxa into plant functional types (PFTs) is aimed to reflect the vegetation in terms
of biomes. The climatic variables are then calibrated on these PFTs using an artificial neural network technique. The method is applied to the glacial steppic vegetation in Europe, using 15 pollen records.

Paleoenvironment reconstructions and climate simulations of the Early Triassic : impact of the water and sediment supply on the preservation of fluvial systems

Paleoenvironment reconstructions and climate simulations of the Early Triassic : impact of the water and sediment supply on the preservation of fluvial systems
On the basis of paleoenvironmental reconstructions and climatic modelling, the AA. investigate the influence of water and sediment supply on the preservation of fluvial systems within a given geodynamic context. This study only covers the West
-Tethys domain, where sedimentological and stratigraphic data allow to check climate simulation results against geological data. The climatic simulations show that paleoclimates differ between Western Europe and North Africa. In Western Europe
