Past temperature reconstructions from deep ice cores: relevance for future climate change
Ice cores provide unique archives of past climate and environmental changes based only on physical processes. Quantitative temperature reconstructions are essential for the comparison between ice core records and climate models. We give an overview of the methods that have been developed to reconstruct past local temperatures from deep ice cores and highlight several points that are relevant fo...
متن کاملImproving climatic signal representation in tropical ice cores: A case study from the Quelccaya Ice Cap, Peru
[1] The published ice core records for Quelccaya, Peru are shown to contain numerous errors in annual layer determination, introduced by the subjective methodology of the original analysis. A newmethodology is presented that aligns and then merges dO sample measurement profiles from the two Quelccaya cores. Absolute dating of the stratigraphy is established by comparison of prominent dust anoma...

متن کاملMicroparticle concentration variations linked with climatic change: evidence from polar ice cores.
The microparticle concentrations in three deep ice cores reveal a substantial increase in the concentration of insoluble particles in the global atmosphere during the latter part of the last major glaciation. The ratio of the average particle concentration in the late glacial strata to that in the Holocene strata is 6/1 for the core from Dome C, Antarctica, 3/1 for the core from Byrd Station, A...
متن کاملIce 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...
