Record‐Breaking Warm Late‐Winter Over Antarctica in 2024: The Role of Western Pacific Warm Pool and Pacific Decadal Oscillation

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Antarctic warm extremes in winter have been one of major concerns because they are sometimes associated with anomalous snowfall and thus increase surface mass balance. Station observations and ERA5 showed that East Antarctic Ice Sheet (EAIS) experienced an unprecedented warm late‐winter (July‐August) in 2024 since the late 1950s.

Regime Shift in Arctic Ocean Sea‐Ice Extent

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract A regime shift is an abrupt, substantial, and persistent change in the state of a system. We show that a regime shift in the September Arctic sea‐ice extent (SIE) occurred in 2007. Before 2007, September SIE was declining approximately linearly.

The Impacts of an AMOC Slowdown on Southern Hemisphere and Australian Climates at 8.2 ka in ACCESS‐ESM1.5 Model

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.
Abstract Greenland ice cores reveal an abrupt cooling of up to 3.3°C 8.2 kyr ago (8.2 ka), lasting for roughly 160 years. The event was likely caused by a weakening of the Atlantic Meridional Overturning Circulation (AMOC) due to freshwater drainage into the North Atlantic.

Patterns of Snow Drought Under Climate Change: From Dry to Warm Dominance

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Global warming may trigger more frequent snow droughts (SD). SD can result from low total precipitation (dry‐SD), high temperatures leading to less solid precipitation (warm‐SD), or a combination of both (dry‐warm compound SD). Those three SD types threaten ecosystems differently. Nevertheless, the regions dominated by SD types, the transition

Constraints on the Projected Tropical SST Response to Greenhouse Warming by the Observed Antarctic Sea Ice Concentration

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The future tropical sea surface temperature (SST) changes profoundly impact global and regional climate. Under greenhouse warming, the reduction of Antarctic sea ice concentration (SIC) acts as an extratropical energy perturbation, exerting a substantial influence on the spatial distribution of tropical SST change.
