Ice Cores , High - Mountain Glaciers , and Climate
The near-global retreat of high-mountain glaciers and the shrinkage of ice fields and ice caps and retreat of their associated outlet glaciers are perhaps the most visible evidence for 20th-century climate change and the recent increase in the globally averaged near-surface temperatures of the Earth’s surface. The loss of high-mountain glaciers—including ice fields, ice caps, and other glaciers...
متن کاملAnnually resolved ice core records of tropical climate variability over the past ~1800 years.
Ice cores from low latitudes can provide a wealth of unique information about past climate in the tropics, but they are difficult to recover and few exist. Here, we report annually resolved ice core records from the Quelccaya ice cap (5670 meters above sea level) in Peru that extend back ~1800 years and provide a high-resolution record of climate variability there. Oxygen isotopic ratios (δ(18)...
متن کاملAnnually resolved North Atlantic marine climate over the last millennium
Owing to the lack of absolutely dated oceanographic information before the modern instrumental period, there is currently significant debate as to the role played by North Atlantic Ocean dynamics in previous climate transitions (for example, Medieval Climate Anomaly-Little Ice Age, MCA-LIA). Here we present analyses of a millennial-length, annually resolved and absolutely dated marine δ18O arch...

متن کاملMillennial climate variability: GCM-simulation and Greenland ice cores
[1] The low frequency variability of the near surface temperature in a climate simulation is compared with Greenland ice core dO time series during the holocene. The simulation is performed with the coupled CSIRO atmosphere-ocean model under present-day conditions. The variability, analyzed by the detrended fluctuation analysis, reveals power-law scaling of the power-spectrum for frequency f, S...
