Atmospheric and Deposition Responses of 10Be to Volcanic Eruptions Inferred From the Aerosol‐Climate Model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract 10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state‐of‐the‐art aerosol‐climate model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance

Change in Tropical Cyclone Efficiency Under Different ENSO Conditions in the Western North Pacific Ocean

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Tropical cyclones (TCs) can be considered as Carnot heat engines, where thermodynamic efficiency depends on the sea surface temperature (SST) and TC outflow temperature (To) in the upper atmosphere. This study investigates how TC efficiency in the western North Pacific (WNP) Ocean varies under different El Niño‐Southern Oscillation (ENSO ...

Independent Short‐ and Longwave Pathways for a Zonally Asymmetric Northern Hemisphere Temperature Response to Tropical Volcanic Eruptions

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Stratospheric sulfate aerosols from tropical volcanic eruptions alter surface air temperatures. Fundamentally, this is due to two different properties of the aerosols: Their ability to reflect incoming solar shortwave radiation, and their ability to absorb terrestrial longwave radiation.

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

The Depositional Record, Volume 11, Issue 5, Page 1376-1398, November 2025.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Lidar measurements of stratospheric aerosol content and depolarization ratios after the eruption of El Chichón volcano: measurements at Nagoya, Japan

Geofísica Internacional, 1984
Después de la erupción de "El Chichón", se observó un enorme aumento en la dispersión de fondo de la luz desde la capa de aerosol estratosférico, utilizando un lidar de rubí en Nagoya, Japón (35ºN, 137ºW).En la parte inferior de la capa principal de ...

Detection of Satellite Sea Surface Temperature Extremes: Low Frequency Variability and Climate Change

Journal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract The occurrence of sea surface temperature (SST) extremes may provoke profound impacts on ocean health. In the last decade, much effort has been dedicated to understanding and systematically describing marine heatwaves (MHWs) and cold spells (MCSs), defined as prolonged periods of anomalously warm or cold SSTs at a given location, respectively.

Eruption Column Modeling of Explosive Volcanism on Venus

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Volcanism on Venus has never been directly observed, but several measurements indicate present‐day activity. Volcanism could potentially play a role in climatic processes on Venus, especially in the sulfur cycle like on Earth. Observation of volcanic activity is the primary objective of future Venus spacecraft. However, there are many unknowns

Social vulnerability of Esquipulas Guayabal town in regard to hazards from El Chichón volcano, México

Natural Hazards Research
El Chichón, the most active volcano in the Chiapaneco Volcanic Arc of southeastern Mexico, erupted explosively in March–April 1982. The eruption caused extensive environmental destruction, significant loss of life, and profound social upheaval.
