Reconstructing Climate from Glaciers
Glaciers offer the potential to reconstruct past climate over timescales from decades to millennia. They are found on nearly every continent, and at the Last Glacial Maximum, glaciers were larger in all regions on Earth. The physics of glacier-climate interaction are relatively well understood, and glacier models can be used to reconstruct past climate from geological evidence of past glacier e...
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...
متن کاملAs climate changes, so do glaciers.
Understanding abrupt climate changes requires detailed spatial/temporal records of such changes, and to make these records, we need rapidly responding, geographically widespread climate trackers. Glacial systems are such trackers, and recent additions to the stratigraphic record show overall synchronous response of glacial systems to climate change reflecting global atmosphere conditions.
متن کاملObliquity-paced climate change recorded in Antarctic debris-covered glaciers
The degree to which debris-covered glaciers record past environmental conditions is debated. Here we describe a novel palaeoclimate archive derived from the surface morphology and internal debris within cold-based debris-covered glaciers in Antarctica. Results show that subtle changes in mass balance impart major changes in the concentration of englacial debris and corresponding surface topogra...
متن کاملWhat do glaciers tell us about climate change?
Glacier are pretty and move around a lot on the landscape due to the random stochastic climate forcing inherent to a constant climate. They obviously also respond to changes in climate. The tricky part is whether, in absence of direct instrumental measurements, climate changes can be inferred from variations in glacier length.
