Interpreting Air Temperature Trends Across the Antarctic Peninsula Between 1979 and 2025

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The near‐surface temperature of the Antarctic Peninsula is marked by strong spatio‐temporal variability. In situ observations are scarce and therefore have limited spatial coverage. Furthermore, ERA‐5 reanalysis does not have a sufficient spatial resolution to capture the steep topography and other climate gradients of the peninsula.

Shipborne Measurements of Mineral Dust and Black Carbon Aerosols Over the Southern Ocean in the Austral Summer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric mineral dust and black carbon (BC) aerosols play important roles in the Earth's climate system, yet direct observations over the Southern Ocean (SO) are scarce. In this study, we present the characteristics of airborne water‐insoluble particles (WIPs) collected during a cruise of the R/V Shirase in the Australian and Indian sectors

Super Warm Early Eocene Simulations With HadGEM3‐GC31‐LL

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract The early Eocene Climatic Optimum (EECO; 53.3–49.1 million years ago) represents the period of greatest sustained warmth in the Cenozoic (last 66 million years), with proxy‐data indicating global‐mean temperatures 10–16°C above preindustrial and atmospheric CO2 ${\text{CO}}_{2}$ concentrations of 1,200–2,500 ppmv.

Antarctic sea ice : a seasonal perspective

Saisonnalité de la banquise antarctique La banquise antarctique a subi une réduction brutale en 2016, après plus de quatre décennies d'une lente augmentation. Une telle évolution pourrait avoir de larges conséquences, compte tenu de l'importance de la banquise antarctique pour le climat, l'océan et l'écosystème marin polaire local ...

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Nonlinear Release of Subinertial Diurnal Internal Tides Forms Spiral Internal Solitary Waves

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Earth's rotation imposes a dynamical barrier on the free propagation of internal tides at high latitudes, raising questions about the fate of tidal energy poleward of the critical latitude. Satellite observations reveal spiral internal solitary waves (ISWs) along the continental slope of the South Orkney Plateau.

Diminished Radiative Cooling With Northward Wildfire Advance in the East Siberian Boreal Region

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Intensification of the Siberian wildfire regime is characterized by large increases in burned area above the Arctic Circle. Wildfire in boreal forests typically reduces albedo in the decades following fire, resulting in a net cooling effect. Here we quantified changes in albedo and the accompanying radiative forcing associated with a northward
