Little Ice Age climate reconstruction from ensemble reanalysis of Alpine glacier fluctuations
Mountain glaciers sample a combination of climate fields – temperature, precipitation and radiation – by accumulation and melting of ice. Flow dynamics acts as a transfer function that maps volume changes to a length response of the glacier terminus. Long histories of terminus positions have been assembled for several glaciers in the Alps. Here I analyze terminus position histories from an ense...

متن کاملThe Economic Effects of Long-Term Climate Change: Evidence from the Little Ice Age, 1500-1750
Understanding the economic effects of long-term and gradual climate change, when people have time to adapt, is a central question in the current debate on climate change. Empirical evidence, however, is scarce. I study the economic effects of climate change over a period of 250 years during the Little Ice Age, a historical episode of climate change, between 1500 and 1750. Historians have argued...
متن کاملThe Medieval Climate Anomaly and the Little Ice Age in the eastern Ecuadorian Andes
To better characterize the climate variability of the last millennium in the high Andes, we analyzed the pollen content of a 1150-yr-old sediment core collected in a bog located at 3800 m a.s.l. in the páramo in the eastern Cordillera in Ecuador. An upslope convective index based on the ratio between cloud transported pollen from the Andean forest to the bog (T) and Poaceae pollen frequencies, ...
متن کاملSolar modulation of Little Ice Age climate in the tropical Andes.
The underlying causes of late-Holocene climate variability in the tropics are incompletely understood. Here we report a 1,500-year reconstruction of climate history and glaciation in the Venezuelan Andes using lake sediments. Four glacial advances occurred between anno Domini (A.D.) 1250 and 1810, coincident with solar-activity minima. Temperature declines of -3.2 +/- 1.4 degrees C and precipit...
