Revisiting the 10th‐Century Eldgjá Eruption: Modeling the Climatic and Environmental Impacts by Herman F. Fuglestvedt, Imogen Gabriel, Michael Sigl, Thorvaldur Thordarson, Kirstin Krüger

“…Earth system modeling of this scenario under pre‐industrial conditions reveals a compound event with maximum northern extratropics surface cooling of ∼2°C in summer‐autumn of 939 and 940 CE, prolonged Arctic sea ice growth, and large‐scale precipitation changes, concurrent with stratospheric ozone depletion and elevated pollution. …”

Amplification of Northern Hemisphere winter stationary waves in a warming world by Jueun Lee, S.-Y. Simon Wang, Seok-Woo Son, Daehyun Kim, Jee-Hoon Jeong, Hyungjun Kim, Jin-Ho Yoon

“…We further show that ocean warming is the primary driver of changes in westerly winds and stationary waves in the Northern Hemisphere. Sea ice losses exert a considerable effect through a different mechanism, complementing the dominant influence of ocean warming on these atmospheric changes. …”

Case studies of different types of precipitation at Ny-Ålesund, Arctic by Lekhraj Saini, Saurabh Das, Nuncio Murukesh

“…Abstract Arctic precipitation plays a crucial role in shaping the surface mass balance of Arctic sea ice and has wide-ranging impacts on local climate, ecosystems, and global sea level dynamics. …”

Migratory behaviour of humpback whales in the southeastern Pacific under climate change by Virginie Millien, Nicole Stafiej, Fernando Félix, Hector M. Guzman

“…We show that whales partly rely on cues they perceive in their immediate environment to initiate their southward migration, but also on their memory of oceanic conditions on their feeding grounds, timing their arrival with the complete melting of sea ice which triggers a bloom of krill in the Antarctic Ocean. …”

The very-high-resolution configuration of the EC-Earth global model for HighResMIP by E. Moreno-Chamarro, E. Moreno-Chamarro, E. Moreno-Chamarro, T. Arsouze, T. Arsouze, M. Acosta, P.-A. Bretonnière, M. Castrillo, E. Ferrer, A. Frigola, D. Kuznetsova, E. Martin-Martinez, P. Ortega, S. Palomas

“…Other biases persist or worsen with increased resolution from LR to VHR, such as the warm bias over the tropical upwelling region and the associated cloud cover underestimation, a precipitation excess over the tropical South Atlantic and North Pacific, and overly thick sea ice and an excess in oceanic mixing in the Arctic. …”

Plausible Last Interglacial Antarctic Ice Sheet Changes Do Not Fully Explain Antarctic Ice Core Water Isotope Records by Huiling Zou, Louise C. Sime, Nancy A. N. Bertler, Elizabeth D. Keller, Eric W. Wolff

“…The remaining discrepancies between the simulated and observed core‐mean water isotope changes suggest that LIG simulations also need to include the influences of reduced Antarctic sea ice, a warmer Southern Ocean, and resultant shifts in vapor source regions to produce a more satisfactory match to δ18O observed at ice core sites.…”

Recent Levels of Technetium-99 in Seawater at the West Coast of Svalbard by Sebastian Gerland, Bjørn Lind, Mark Dowdall, Anne Kathrine Kolstad

Dominant inflation of the Arctic Ocean’s Beaufort Gyre in a warming climate by Qiang Wang, Qi Shu, Shizhu Wang, Xinyue Li, Sergey Danilov, Fangli Qiao, Zhenya Song, Fan Wang, Thomas Jung

“…The inflation is driven by increased surface freshwater fluxes and intensified surface stress from wind strengthening and sea ice decline. Current climate models tend to underestimate this inflation, which could be alleviated by high-resolution ocean models and improved atmospheric circulation simulations. …”

Rapid Emulation of Spatially Resolved Temperature Response to Effective Radiative Forcing by Christopher B. Womack, Paolo Giani, Sebastian D. Eastham, Noelle E. Selin

“…These errors are likely driven by state‐dependent climate feedbacks, such as the non‐linear effects of Arctic sea ice melt. We additionally show an illustrative example of our emulator for policy evaluation and impact analysis, emulating spatially resolved temperature change for a 1,000 member scenario ensemble in less than a second.…”

Loss of pelagic fish and zooplankton density associated with subglacial upwelling in high Arctic estuaries may be mitigated by benthic habitat expansion following tidewater glacier... by Victor Gonzalez Triginer, Arunima Sen, Maxime Geoffroy, Børge Damsgård

“…In shallow fjords and areas with hard bottom substrate, it is expected that sea-ice and glacial retreat will promote macroalgal settlement, and we suggest that macroalgal expansion may compensate the loss of tidewater glacier-associated density of fish and zooplankton by the increase of benthic-driven density. …”

“…This study uses a set of high-resolution preindustrial control, historical and transient simulations with the Community Earth System Model (CESM) with a nominal horizontal resolution of 0.1° for the ocean and sea ice and 0.25° for the atmosphere and land. At these resolutions, the model represents the necessary scales to investigate Agulhas Leakage transport variability and its relation to the AMOC. …”
