| Zusammenfassung |
| This paper reviews multi-proxy paleoclimatic reconstructions with robust
age-control derived from lacustrine, dendrochronological and
geomorphological records and characterizes the main environmental changes
that occurred in the Southern Pyrenees during the last millennium. Warmer
and relatively arid conditions prevailed during the Medieval Climate Anomaly
(MCA, ca. 900–1300 AD), with a significant development of xerophytes and
Mediterranean vegetation and limited deciduous tree formations (mesophytes).
The Little Ice Age (LIA, 1300–1800 AD) was generally colder and moister,
with an expansion of deciduous taxa and cold-adapted montane conifers. Two
major phases occurred within this period: (i) a transition MCA–LIA,
characterized by fluctuating, moist conditions and relatively cold
temperatures (ca. 1300 and 1600 AD); and (ii) a second period, characterized
by the coldest and most humid conditions, coinciding with maximum (recent)
glacier advances (ca. 1600–1800 AD). Glaciers retreated after the LIA when
warmer and more arid conditions dominated, interrupted by a short-living
cooling episode during the late 19th to early 20th centuries. Some
records suggest a response to solar activity with colder and slightly
moister conditions during solar minima. Centennial-scale hydrological
fluctuations are in phase with reconstructions of NAO variability, which
appears to be one of the main climate mechanisms influencing rainfall
variations in the region during the last millennium. |
