Historical Volcanic Eruptions Mitigated the Expected Rapid Arctic Sea Ice Decline Prior to 2000

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Arctic sea ice has declined at sharply contrasting rates over the past four decades—modest before 2000 and rapid thereafter. Using observational and model evidence, we show that large tropical volcanic eruptions can trigger decade‐long Arctic sea ice recoveries, and that without the 1982 El Chichón and 1991 Pinatubo eruptions, Arctic sea ice ...

Uptake of stratospheric species on minerals proposed for stratospheric aerosol injection

Solid mineral-based particles have been proposed as alternatives to sulfates for climate intervention by stratospheric aerosol injection, as a means for improving optical or chemical characteristics and thereby minimize risks and uncertainties. However, the heterogeneous reactivity of solid particles with stratospheric trace gases, and possible ...

Microphysical Simulation of the 2022 Hunga Volcano Eruption Using a Sectional Aerosol Model

Geophysical Research Letters
Approximately 150 Tg of water vapor and 0.42 Tg of sulfur dioxide were injected directly into the stratosphere by the January 2022 Hunga volcanic eruption, which represents the largest water vapor injection in the satellite era. A comparison of numerical

Solar Geoengineering Effects on Malaria Transmission Risk in South Asia Under G6sulfur Scenario

International Journal of Climatology, Volume 46, Issue 7, 15 June 2026.
Comparison of EIR (unit: No of infected bites per person per day) for each considered country in South Asia, under the considered scenarios, averaged over the period 2020–2090. A regression equation is shown for each country (for Bhutan EIRG = 0.1690 × 10−10 EIRS + 0.5968 × 10−12) to illustrate the projected trend.

The impact of stratospheric aerosol injection: a regional case study

Frontiers in Climate
Stratospheric aerosol injection (SAI) is a form of climate intervention that has been proposed to limit future warming and mitigate some of the adverse impacts of climate change while humanity continues efforts to reduce emissions and atmospheric concentrations of greenhouse gases.

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

Investigating the zero transmission problem in satellite solar occultation measurements in the context of possible stratospheric aerosol injections [PDF]

Atmospheric Measurement Techniques
Stratospheric aerosol injections have been proposed to mitigate the effects of global warming. The injection of sulphur dioxide into the stratosphere is one possible idea.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Stratospheric circulation response to stratospheric aerosol injections remains uncertain.

Abstract Mitigating global warming through stratospheric aerosol injection (SAI), which aims to reproduce the cooling effects of tropical volcanoes on surface climate, is emerging as a potential strategy for limiting near–surface global warming to around 1.5–2◦C above pre–industrial levels.
