The Greenland Ice Sheet contributed 6.9 ± 0.4 mm to sea-level from April 2011 to April 2020

Satellite altimetry suggests a peak annual ice loss of 498 ± 45 Gt from April 2019 to April 2020

The terminus of Jakobshavn Isbræ is once again dynamically thinning, following a period of dynamic thickening during 2016–2018

The presented permafrost thermal record is the second northernmost in the Arctic and reveals the warmest known permafrost north of 80°N

The warming rate at 20 m depth was 0.07°C/year and 0.05°C/year at the two sites from 2014 to 2021 despite thick and long-lasting snow cover

Epigenetic permafrost grew into sands and gravels deposited during deglaciation and isostatic emergence of the Prinsesse Ingeborg Halvø

We detect tiny spatiotemporal moisture variations below a hyper-arid mobile dune with a new capacitance instrument

We predict moisture profiles, internal waves and wind-driven pore advection. Grain evaporation is a kinetic-limited, activated process

The moisture surface flux is weaker than expected, and not always proportional to the mass fraction difference between surface and ambient

We report updated winter velocity and surface elevation change estimates for four major basins on the Prince of Wales Icefield

Flow for Trinity, Wykeham, Cadogan, and Ekblaw glaciers is strongly influenced by bed topography

Velocity changes, surface thinning, and terminus buoyancy resulted in instability and near flotation of the termini of Trinity and Wykeham glaciers

Propagation rates of morphologic features determined by nuclide concentration gradients along a horizontal transect

Uplift rate of the Florida panhandle estimated between 0.027 and 0.038 mm/y from a nuclide depth profile

Changes in climate over the Quaternary likely drove variable growth rates of seepage valleys along the Apalachicola River

Mar Chiquita, the largest South American shrinking saline lake, has emitted ∼0.5 Tg of dust in August plus September of each year since 2004

Despite a marked dust enrichment in soluble sodium, dust inputs are low compared to agricultural soil sodium stocks at most studied sites

While short-term soil sodification risk is low, potential long-term effects and projected stronger dust emissions merit soil monitoring

Cosmogenic ¹⁰Be, ¹⁴C, and ³He is used to determine erosion rates, erosion styles, and bedrock temperatures in cold regions

¹⁴C/¹⁰Be ratios of surface samples reflect the depth at which material was previously eroded, allowing for determination of erosion style

¹⁴C/¹⁰Be ratios combined with ¹⁰Be-derived erosion rates improve erosion rate estimates in stochastically eroding environments

We monitored subsurface pore pressures and micrometer scale strain in a rock slope during strong glacial retreat caused by climate warming

We identified thermo-hydro-mechanical drivers for reversible deformation and irreversible rock mass damage acting at various timescales

Slope damage intensity can be related to landslide spatial and temporal distribution

A strategic plan for JGR Earth Surface is presented, in alignment with AGU's goals and objectives

The editors thank the 2021 peer reviewers

Co-reviewing protocols are explained and encouraged

Erosion frequency and surface damage modulate the spatial variability in mechanical properties of bedrock channels

Grain size and mineralogy control damage by weathering and abrasion, which influence the slope, width, and roughness of bedrock channels

The relation between rock damage and rock-erodibility is unique for different lithologies

The glaciers of the Olympus Peninsula are shrinking rapidly, losing half of its ice-covered area since 1900

Warming air temperatures are causing glacier loss; warming winter temperatures change the phase of the precipitation from snow to rain

Modeling suggests the glaciers will largely disappear by 2070

Sediment flux in deforming till varies non-monotonically with effective stress

The relationship between sediment flux and the speed of basal ice is nearly linear

Coupling between ice and till causes the grain velocity profile of the bed to scale with slip speed
