Large-Scale Temperature Changes Across the Southern Andes: 20th-Century Variations in the Context of the Past 400 Years
Ricardo Villalba,Antonio Lara,José A. Boninsegna,Mariano H. Masiokas,Silvia Marcela Delgado,Juan Carlos Aravena,Fidel A. Roig,Andrea Schmelter,Alexia Wolodarsky,Alberto Ripalta +9 more
TL;DR: In this paper, a critical appraisal of surface air temperature from station records is presented for southern South America during the 20th century, for the interval 1930-1990, three major patterns in temperature trends are identified.
Journal ArticleDOI

Boninsegna,Ana Marina Srur,Mariano S. Morales,Diego Christian Araneo,Jonathan G. Palmer,Emilio Cuq,Juan Carlos Aravena,Andrés Holz,Carlos LeQuesne +20 more
TL;DR: In this article, the authors used tree-ring records from over 3,000 trees in South America, Tasmania and New Zealand to identify dominant patterns of tree growth in recent centuries and showed that the foremost patterns of growth between 1950 and 2000 differed significantly from those in the previous 250 years.
Journal ArticleDOI
Snowpack Variations in the Central Andes of Argentina and Chile, 1951–2005: Large-Scale Atmospheric Influences and Implications for Water Resources in the Region
TL;DR: In this article, the authors developed the first regional snowpack series (1951-2005) from Chilean and Argentinean snow course records, showing a strong regional signal, marked interannual variability, and a positive, though nonsignificant, linear trend.
Journal ArticleDOI

Mariano Masiokas,Andrés Rivera,Andrés Rivera,Lydia E. Espizua,Ricardo Villalba,Silvia Marcela Delgado,Juan Carlos Aravena +6 more
TL;DR: In this paper, the authors presented an updated, extensive review of glacier fluctuations during the past 1000 years in the extratropical Andes of South America between ca. 17° and 55°S.
Journal ArticleDOI

TL;DR: In this article, the authors statistically reconstruct austral summer and winter air temperature fields back to AD 900 (1706) using 22 (20) annually resolved predictors from natural and human archives from southern South America (SSA).
