I constructed a temperature history for different parts of the world from 169 glacier length records. Using a first-order theory of glacier dynamics, I related changes in glacier length to changes in temperature. The derived temperature histories are fully independent of proxy and instrumental data used in earlier reconstructions. Moderate global warming started in the middle of the 19th century. The reconstructed warming in the first half of the 20th century is 0.5 kelvin. This warming was… 

Temperature reconstruction from glacier length fluctuations in the Himalaya

Abstract A temperature reconstruction in the glacierized Himalaya over the past centuries using glacial length fluctuation records is challenging due to the abundance of debris-covered glaciers and a

Reconstructing the glacier contribution to sea-level rise back to 1850

Abstract. We present a method to estimate the glacier contribution to sea-level rise from glacier length records. These records form the only direct evidence of glacier changes prior to 1946, when

Global and hemispheric temperature reconstruction from glacier length fluctuations

Temperature reconstructions for recent centuries provide a historical context for the warming over the twentieth century. We reconstruct annual averaged surface temperatures of the past 400 years on

Understanding drivers of glacier-length variability over the last millennium

Abstract. Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation resulting from both external forcing (e.g., volcanic eruptions or

Understanding drivers of glacier-length variability over the last millennium

Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation resulting from both external forcing (e.g., volcanic eruptions or anthropogenic CO2)

Glacier response to North Atlantic climate variability during the Holocene

Abstract. Small glaciers and ice caps respond rapidly to climate variations, and records of their past extent provide information on the natural envelope of past climate variability. Millennial-scale

A data set of worldwide glacier length fluctuations

Glacier fluctuations contribute to variations in sea level and historical glacier length fluctuations are natural indicators of past climate change. To study these subjects, long-term information of

Analysis of Alpine glacier length change records with a macroscopic glacier model

Abstract. The length change record of 91 glaciers in the Swiss Alps was analyzed with a novel macroscopic glacier model (LV-model). Based on a history of equilibrium line variations, synthetic length

The response of glaciers to intrinsic climate variability: observations and models of late-Holocene variations in the Pacific Northwest

Abstract Discriminating between glacier variations due to natural climate variability and those due to true climate change is crucial for the interpretation and attribution of past glacier changes,



Quantifying Global Warming from the Retreat of Glaciers

Records of glacier fluctuations compiled by the World Glacier Monitoring Service can be used to derive an independent estimate of global warming during the last 100 years and can be explained by a linear warming trend of 0.66 kelvin per century.

The relation between changes in modern glaciers, not including the ice sheets of Greenland and Antarctica, and their climatic environment is investigated to shed light on paleoglacier evidence of

Contribution of Small Glaciers to Global Sea Level

Although the error band is large, these glaciers appear to account for a third to half of observed rise in sea level, approximately that fraction not explained by thermal expansion of the ocean.

Glaciers and climate change

This text brings together meteorology and the theory of glacier flow, providing a fundamental understanding of how glaciers respond to climate change. Attention is paid to the microclimate of

Modelling the response of glaciers to climate warming

Abstract Dynamic ice-flow models for 12 glaciers and ice caps have been forced with various climate change scenarios. The volume of this sample spans three orders of magnitude. Six climate scenarios

Deriving historical equilibrium-line altitudes from a glacier length record by linear inverse modelling

Glaciers have fluctuated in historic times and the length fluctuations of many glaciers are known. From these glacier length records, a climate reconstruction described in terms of a reconstruction

A flowline model for Nigardsbreen, Norway: projection of future glacier length based on dynamic calibration with the historic record

Historic glacier-length variations are used to constrain a computer model for Nigardsbreen, Norway. A mass-balance history is derived that, when imposed on the flow model, gives an almost perfect

Late Holocene glacier variations and climate at Jan Mayen

Jan Mayen is a small (373 km2) remote island in the Norwegian Sea. One third of it is covered by glaciers, all located on the Beerenberg volcano. There have been at least two Holocene periods of

Glaciological investigations at Nigardsbreen, Norway

One of the largest outlet glaciers from the ice cap Jostedalsbreen has been studied by various scientists during the 19th and 20th centuries, and a detailed programme of mass balance investigations

Global surface temperatures over the past two millennia

We present reconstructions of Northern and Southern Hemisphere mean surface temperature over the past two millennia based on high‐resolution ‘proxy’ temperature data which retain millennial‐scale
