Forecasting Climate Change Using a Multivariate Cointegrated System

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A cointegrated vector equilibrium correction model of key climate variables including sea surface temperature, ocean heat content, Arctic sea‐ice extent and sea‐level change is built, driven by radiative forcing in which a stochastic trend arises due to anthropogenic emissions of greenhouse gases.

Greenland Ice Sheet Response to Stratospheric Aerosol Injection Geoengineering

Earth's Future, 2019
The Greenland ice sheet is expected lose at least 90% of its current volume if ice sheet summer temperatures warm by around 1.8 °C above pre‐industrial. Geoengineering by stratospheric sulfate aerosol injection might slow Greenland ice sheet melting and ...

Unusual Radar Echoes from the Greenland Ice Sheet [PDF]

Science, 1993
Airborne radar images of part of the Greenland ice sheet reveal icy terrain whose radar properties are unique among radar-studied terrestrial surfaces but resemble those of Jupiter's icy Galilean satellites. The 5.6- and 24-centimeter-wavelength echoes from the Greenland percolation zone, like the 3.5- and 13-centimeter-wavelength echoes from the icy ...

A high resolution record of Greenland mass balance [PDF]

, 2016
We map recent Greenland Ice Sheet elevation change at high spatial (5-km) and temporal (monthly) resolution using CryoSat-2 altimetry. After correcting for the impact of changing snowpack properties associated with unprecedented surface melting in 2012 ...

Radiostratigraphy Reflects the Present-Day, Internal Ice Flow Field in the Ablation Zone of Western Greenland

Frontiers in Earth Science, 2018
Englacial radar reflectors in the ablation zone of the Greenland Ice Sheet are derived from layering deposited in the accumulation zone over past millennia. The original layer structure is distorted by ice flow toward the margin.

Impact of ocean stratification on submarine melting of a major Greenland outlet glacier [PDF]

, 2011
Submarine melting is an important balance term for tidewater glaciers1,2 and recent observations point to a change in the submarine melt rate as a potential trigger for the widespread acceleration of outlet glaciers in Greenland3-5.

A last glacial ice sheet on the Pacific Russian coast and catastrophic change arising from coupled ice–volcanic interaction [PDF]

, 2008
Controversy exists over the extent of glaciation in Eastern Asia at the Last Glacial Maximum: complete ice sheet cover vs. restricted mountain icefields (an area discrepancy equivalent to 3.7 Greenland Ice Sheets).

Rates of Sea‐Level Rise Are Highly Sensitive to Ice Viscosity Parameters in Model Benchmarks

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Glacier flow plays a major role in current and future rates of globally averaged sea‐level rise. The viscosity of glacial ice, controlling the rate of flow, decreases as stress increases and is highly sensitive to the value of the stress exponent, n $n$, in the constitutive equation for viscous flow.

Jökulhlaup Observed at Greenland Ice Sheet

Eos, Transactions American Geophysical Union, 2008
On 31 August 2007, about 35 kilometers upstream from the town of Kangerlussuaq, in western Greenland, a roughly 0.5‐square‐kilometer permanently ice‐dammed lake on the northern flank of the Russell Glacier—an outlet glacier of the Greenland Ice Sheet—suddenly broke free and drained into the Watson River (Figure 1).

Improved retrieval of land ice topography from CryoSat-2 data and its impact for volume-change estimation of the Greenland Ice Sheet [PDF]

, 2016
A new methodology for retrieval of glacier and ice sheet elevations and elevation changes from CryoSat-2 data is presented. Surface elevations and elevation changes determined using this approach show significant improvements over ESA's publicly ...
