Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

New Phytologist, EarlyView.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Recent Ice-Sheet Growth in the Interior of Greenland [PDF]

Science, 2005
A continuous data set of Greenland Ice Sheet altimeter height from European Remote Sensing satellites (ERS-1 and ERS-2), 1992 to 2003, has been analyzed. An increase of 6.4 ± 0.2 centimeters per year (cm/year) is found in the vast interior areas above 1500 meters, in contrast to previous reports of high-elevation balance.

Monitoring of the Greenland ice sheet using a broadband seismometer network: the GLISN project

Antarctic Record, 2014
Global climate change is currently causing melting of the Greenland ice sheet. Recently, a new type of seismic event, referred to as a "glacial earthquake", has been recognized.

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.

Changes in the Velocity Structure of the Greenland Ice Sheet [PDF]

Science, 2006
Using satellite radar interferometry observations of Greenland, we detected widespread glacier acceleration below 66° north between 1996 and 2000, which rapidly expanded to 70° north in 2005. Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year.

Heterogeneous impacts of ocean thermal forcing on ice discharge from Greenland's peripheral tidewater glaciers over 2000–2021

Scientific Reports
The Greenland Ice Sheet is losing mass at increasing rates. Substantial amounts of this mass loss occur by ice discharge which is influenced by ocean thermal forcing. The ice sheet is surrounded by thousands of peripheral, dynamically decoupled glaciers.

Recent Progress in Greenland Ice Sheet Modelling [PDF]

Current Climate Change Reports, 2017
This paper reviews the recent literature on numerical modelling of the dynamics of the Greenland ice sheet with the goal of providing an overview of advancements and to highlight important directions of future research. In particular, the review is focused on large-scale modelling of the ice sheet, including future projections, model parameterisations,

Quantification of the Greenland ice sheet contribution to Last Interglacial sea level rise [PDF]

Climate of the Past, 2013
During the Last Interglacial period (~ 130–115 thousand years ago) the Arctic climate was warmer than today, and global mean sea level was probably more than 6.6 m higher.

Refreezing on the Greenland ice sheet: a comparison of parameterizations [PDF]

The Cryosphere, 2012
Abstract. Retention and refreezing of meltwater are acknowledged to be important processes for the mass budget of polar glaciers and ice sheets. Several parameterizations of these processes exist for use in energy and mass balance models. Due to a lack of direct observations, validation of these parameterizations is difficult.

Deployment Strategy Shapes the Polar Climate Response to Marine Cloud Brightening

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Marine cloud brightening (MCB) is a proposed solar climate intervention strategy that increases marine cloud reflectivity to cool Earth's surface. While previous studies have largely examined its global temperature and precipitation effects, little is known about how MCB deployment strategies influence polar climate and sea ice.
