A 400‐Year Antarctic Ice‐Core Perchlorate Record Reveals Variability in Stratospheric Chlorine Chemistry

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Perchlorate (ClO4−) in polar ice preserves past chlorine oxidation chemistry; however, multi‐centennial Antarctic ClO4− records and the mechanisms controlling their variability remain poorly constrained. Here, we present the first 400‐year (1616−2016) ClO4− record from an Antarctic ice core, revealing two regimes separated around 1980.

Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Thermodynamic Control of Global Seasonal Snow Decline

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Seasonal snowfall is declining globally, yet the relative roles of precipitation variability versus warming‐induced phase transitions remain poorly quantified. We develop a physically based attribution framework that decomposes snowfall trends (1983–2023) into hydrological (precipitation‐driven) and thermodynamic (phase‐driven) components ...

Role of Shortwave Feedback in Non‐Linear Response to CO2 Forcing in GFDL CM4.0

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Effective climate sensitivity (EffCS) is a key metric for quantifying climate change, yet its uncertainty remains large, primarily due to intermodel differences in cloud feedback. Here, we assess EffCS and climate feedback to an abrupt doubling (2xCO2) and quadrupling (4xCO2) of CO2 over 450 years in GFDL CM4.0. Both runs have comparable EffCS
