“…Smaller stromatolites located stratigraphically closer to the current shore are dated 11 210 ± 120 years. These results are consistent with the large paleolake being formed during the Holocene wet climate episode (Messerli et al, 1993;Wirrmann and Mourguiart, 1995;Grosjean et al, 1995;Baucom and Rigsby, 1999;Sylvestre et al, 1999;Vuille et al, 2003). Below this stratigraphic level, and closer to the current active shoreline, the density of fossil structures is scarce.…”

“…Most of the brackish lagunas in the Bolivian Altiplano were formed as freshwater lakes and experienced their peak volumes during the early Holocene between 18 000 and 9200 BP, when precipitation reached 400À500 mm/yr (Tauca phase, Messerli et al, 1993;Wirrmann and Mourguiart, 1995;Grosjean et al, 1995;Baucom and Rigsby, 1999;Sylvestre et al, 1999;Vuille et al, 2003). Our topographic survey using Global Positioning System (GPS) and Laser Range Finder shows that the two lagunas were originally one large ($20 Â 3 km), deep ($55 m) lake which has receded significantly since its formation.…”

“…Analysis of high-elevation stations on the Tibetan Plateau over showed no significant correlations between elevation and trend magnitudes of temperature extremes, except for coldest day temperature (You et al, 2008). In South America, lower elevations to the west of the Andes have experienced the greatest warming, while warming at higher elevations to the east is less marked (Vuille et al, 2003). Analysis of 1084 stations from the Global Historical Climate Network (GHCN) and Climate Research Unit (CRU) datasets by Pepin and Seidel, (2005) did not yield systematic relationships between temperature trends and elevation.…”

South Asia covers more than 30°of latitude with weather observation stations situated from 6°N at Galle, Sri Lanka, to 36°N at Chitral in Pakistan. Moreover, the South Asian station network ranges in altitude from sea level to nearly 4000 m above sea level. This paper uses time series of 11 objectively defined indices of daily temperature extremes at 197 stations in Bangladesh, India, Nepal, Pakistan and Sri Lanka to examine the possible impacts of elevation and latitude on changes in temperature extremes over the period of 1971-2000. Trends in extreme indices are consistent with general warming only at low altitudes and latitudes. Stations at high altitudes and latitudes show both positive and negative trends in extreme temperature indices. As a notable example, the Diurnal Temperature Range (DTR), which has been known to decrease in most parts of the globe, has increasing trends over many high altitude stations in South Asia. Trends in extreme temperature indices at stations in South Asia higher than 2000 m above sea level are mostly in disagreement with those reported over the Tibetan Plateau. Observed trends at low altitude locations in South Asia suggest that these sites can generally expect future changes in temperature extremes that are consistent with broad-scale warming. High-elevation sites appear to be more influenced by local factors and, hence, future changes in temperature extremes may be less predictable for these locations.

“…Against the background of the global average surface temperature increase (especially since about 1950) (Solomon et al 2007), and the rapid retreat of mountain glaciers around the world (particularly in the Himalaya, Andes and Alps) (Solomon et al 2007), huge efforts have been made to explore the features and impacts of climate change in high-elevation regions Beniston 2003;Rangwala and Miller 2012). However, despite numerous studies in the past decades (Beniston and Rebetez 1996;Diaz and Bradley 1997;Liu and Hou 1998;Liu and Chen 2000;Vuille and Bradley 2000;Pepin and Losleben 2002;Vuille et al 2003;Pepin and Seidel 2005;Diaz and Eischeid 2007;Appenzeller et al 2008;Pepin and Lundquist 2008;You et al 2008You et al , 2010Liu et al 2009;Lu et al 2010), our understanding of whether elevationdependent warming commonly occurs in high-elevation regions, and whether high-elevation regions are warming faster than their low elevation counterparts, remains uncertain (Rangwala and Miller 2012).…”

Recent warming amplification over high elevation regions across the globe

Despite numerous studies in recent decades, our understanding of whether warming amplification is prevalent in high-elevation regions remains uncertain. In this work, on the basis of annual mean temperature series of 2,367 stations around the globe, we examine both altitudinal amplification and regional amplification in the high elevation regions across the globe using new methodology. We develop the function equations of warming components of altitude, latitude and longitude and station warming rates for individual stations within a high-elevation region based on basic mathematic and physical principles, and find a significant altitudinal amplification trend for the Tibetan Plateau, Loess Plateau, Yunnan-Guizhou Plateau, Alps, United States Rockies, Appalachian Mountains, South American Andes and Mongolian Plateau. At the same time, we detect a greater warming for four high-elevation regions than their low elevation counterparts for the paired regions available. These suggest that warming amplification in high-elevation regions is an intrinsic feature of recent global warming.
