The observed annual maximum landfast ice (LFI) thickness off Zhongshan (Davis) was 1.59±0.17?m (1.64±0.08?m). Larger interannual and local spatial variabilities for the seasonality of LFI were identified at Zhongshan, with the dominant influencing factors of air temperature anomaly, snow atop, local topography and wind regime, and oceanic heat flux. The variability of LFI properties across the study domain prevailed at interannual timescales, over any trend during the recent decades.

How glaciers have responded to climate change over the last 20 years is well-known, but earlier data are much more scarce. The authors change this in Switzerland by using 22,000 photographs taken from mountain tops between the world wars and find a halving of Swiss glacier volume since 1931. This was done through new automated processing techniques that the authors created. The data are interesting for more than just glaciers, such as mapping forest changes, landslides, and human impacts on the terrain.

For the first time, a dramatic retreat of the grounding line of Petermann Glacier, a major glacier of the Greenland Ice Sheet, was detected. Using satellite data, also a speedup of the glacier and a fracturing of the ice shelf was observed. This sequence of events is coherent with ocean warming in this region and suggests that Petermann Glacier has initiated a phase of destabilization, which is of prime importance for the stability and future contribution of the Greenland Ice Sheet to sea level rise

Snow depth data are essential to monitor the impacts of climate change on sea ice volume variations and their impacts on the climate system. For that purpose, the authors present and assess the altimetric snow depth product, computed in both hemispheres from CryoSat-2 and SARAL satellite data.

In April 2021 the EGU Publications Committee launched the first author survey to routinely ask authors about their publishing experience in EGU journals, in order to learn more about how EGU and Copernicus can serve the scientific community with their publications. Over the last 6 months, 160 contact authors answered the survey representing about 10% of the papers published during this time. We are delighted about the positive feedback and thank all authors. Please read the full report.

The journal metrics were updated and the current numbers are available from the journal metrics overview.

Summer sea ice thickness observations based on electromagnetic induction measurements north of Fram Strait show a 20 % reduction in mean and modal ice thickness from 2001–2020. The observed variability is caused by changes in drift speeds and consequential variations in sea ice age and number of freezing-degree days.

Recently, discussions have focused on the difference in limiting the increase in global average temperatures to below 1.0, 1.5, or 2.0 °C compared to preindustrial levels. Here, the authors assess the impacts that such different scenarios would have on both the future evolution of glaciers in the European Alps and the water resources they provide.

The authors re-estimate pan-Arctic sea ice thickness (SIT) values by combining data from the Envisat and CryoSat-2 missions with data from a new, reanalysis-driven snow model.

The authors study the creep and fracture behavior of 3 m × 6 m floating edge-cracked rectangular plates of warm columnar freshwater S2 ice under creep/cyclic-recovery loading and monotonic loading to fracture.

The unexpected September 2019 calving event from the Amery Ice Shelf, the largest since 1963 and which occurred almost a decade earlier than expected, was triggered by atmospheric extremes.

The surface of the Greenland Ice Sheet contains thousands of surface lakes. These lakes can deliver water through cracks to the ice sheet base and influence the speed of ice flow. Here the authors look at instances of lakes draining in the middle of winter using the Sentinel-1 radar satellites.

The first Alpine-wide assessment of station snow depth has been enabled by a collaborative effort of the research community which involves more than 30 partners, 6 countries, and more than 2000 stations.

Ice shelves are thick floating layers of glacier ice extending from the glaciers on land that buttress much of the Antarctic Ice Sheet and help to protect it from losing ice to the ocean. However, the stability of ice shelves is vulnerable to meltwater lakes that form on their surfaces during the summer.

Satellite observations are the best method for tracking ice loss, because the cryosphere is vast and remote. Using these, and some numerical models, the authors show that Earth has lost 28 trillion tonnes (Tt) of ice since 1994.

The authors present radiative forcing (RF) estimates by snow algae in the Antarctic Peninsula (AP) region from multi-year measurements of solar radiation and ground-based hyperspectral characterization of red and green snow algae collected during a brief field expedition in austral summer 2018.

In this paper the authors show that plutonium is an effective tracer to identify ice originating from the early 1960s at the surface of a mountain glacier after a long time within the ice flow, giving unique information on the long-term former ice motion. Combined with ice flow modelling, the dating can be extended to the entire glacier, and the authors show that an airplane which crash-landed on the Gauligletscher in 1946 will likely soon be released from the ice close to the place where pieces have emerged in recent years.

In summer 2018, northwestern Alaska was affected by widespread lake drainage which strongly exceeded previous observations. The authors of this paper analyzed the spatial and temporal patterns with remote sensing observations, weather data and lake-ice simulations. The preceding fall and winter season was the second warmest and wettest on record, causing the destabilization of permafrost and elevated water levels which likely led to widespread and rapid lake drainage during or right after ice breakup.

The topography of the rock below the Greenland ice sheet is not well known. One long valley appears as a line of dips because of incomplete data. So the authors use ice model simulations that unblock this valley, and these create a watercourse that may represent a form of river over 1000 km long under the ice.

An international effort that brought together more than 60 ice, oceanic and atmospheric scientists from 3 dozen international institutions has generated new estimates of how much of an impact Earth's melting ice sheets could have on global sea levels by 2100. If greenhouse gas emissions continue apace, Greenland and Antarctica's ice sheets could together contribute more than 38 centimetres (15 inches) of global sea level rise – and that's beyond the amount that has already been set in motion by Earth's warming climate. These new results, published this week in a special issue of TC, come from the Ice Sheet Model Intercomparison Project (ISMIP6) led by NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Newly discovered deep seabed channels beneath Thwaites Glacier in West Antarctica may be the pathway for warm ocean water to melt the underside of the ice. Data from two research missions, using aircraft and ship, are helping scientists to understand the contribution this huge and remote glacier is likely to make to future global sea level rise. Two research papers published today in TC describe the discovery.

The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed in December 2018 off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia. Please read the study that MOSAiC experts have published now in The Cryosphere, and which will provide the basis for numerous upcoming scientific assessments.

New research on how glaciers in the European Alps will fare under a warming climate has come up with concerning results. Under a limited warming scenario, glaciers would lose about two-thirds of their present-day ice volume, while under strong warming, the Alps would be mostly ice free by 2100. The results, now published in The Cryosphere, are presented today (9 April) at the EGU General Assembly 2019 in Vienna, Austria.

Targeted engineering projects to hold off glacier melting could slow down the collapse of ice sheets and limit sea-level rise, according to a new study published in TC. While an intervention similar in size to existing large civil engineering projects could only have a 30% chance of success, a larger project would have better odds of holding off ice-sheet collapse. But study authors Michael Wolovick and John Moore caution that reducing emissions still remains key to stopping climate change and its dramatic effects.

An international team of scientists has shown how much sea level would rise if Larsen C and George VI, two Antarctic ice shelves at risk of collapse, were to break up. The research is published today in TC.
