Highland Pathways Shape Global Dust Vertical Transport and Its Climate Effects

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Highlands govern global dust vertical transport, yet their region‐specific pathways and climatic impacts remain unclear. We found that although dust emissions from highlands are minimal, the dust content in the middle and upper atmosphere over highlands is high, identifying highlands as key dust conduits.

Geoengineering as an alternative to mitigation: specification and dynamic implications [PDF]

Geoengineering, i.e. the use of artificial techniques aiming at cooling the planet, is increasingly considered as a realistic alternative to emission mitigation.

Assessing terrestrial biogeochemical feedbacks in a strategically geoengineered climate

Environmental Research Letters, 2020
Geoengineering by injecting sulfur dioxide (SO _2 ) into the lower stratosphere has been suggested to reduce anthropogenically induced warming. While impacts of such geoengineering on climate have been investigated in recent decades, few modeling studies

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.

Northern Hemisphere Wintertime Stratospheric Circulation Response to Smoke Injection From a Regional Nuclear Conflict

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Tropical stratospheric aerosol injections are known to strengthen the wintertime Stratospheric Polar Vortex (SPV). Here, we revisit the circulation response to aerosol perturbations during the first month following injection using chemistry‐climate model simulations of regional nuclear war scenarios.

The Influence of Stratospheric Sulphate Aerosol Deployment on the Surface Air Temperature and the Risk of an Abrupt Global Warming

Atmosphere, 2010
We used the ‘Radiative-Convective Model of the Earth-atmosphere system’ (OGIM) to investigate the cooling effects induced by sulphur injections into the stratosphere.

Radiative Forcing and Ozone Depletion of a Decade of Satellite Megaconstellation Missions

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Satellite megaconstellations (SMCs) are driving rapid increases in rocket launch and re‐entry rates, emitting pollutants throughout the atmosphere. The environmental impact of SMCs lacks characterization to determine the need for regulation. We utilize a global 3D emission inventory of recent (2020–2022) space activity that distinguishes SMC ...

Past Field Experiments of Solar Radiation Modification: A Review of the Scientific and Technical Aspects for Governance

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract As global warming intensifies, Solar Radiation Modification (SRM) has drawn increasing scientific and policy interest as a potential means to temporarily offset climate impacts. This review examines past SRM (or SRM‐like) field experiments, categorized into three primary techniques: Tropospheric and Stratospheric Aerosol Injection (SAI ...

Correction to “Sulfuric acid deposition from stratospheric geoengineering with sulfate aerosols” [PDF]

Journal of Geophysical Research: Atmospheres, 2010
[1] In the paper “Sulfuric acid deposition from stratospheric geoengineering with sulfate aerosols” (Journal of Geophysical Research, 114, D14109, doi:10.1029/2009JD011918, 2009), there are two errors that wewould like to correct. The first is an arithmetic error.

Differentiating Solar Radiation Modification Field Experiments: Scale, Technical Characteristics, and Governance Implications

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Proposed solar radiation modification (SRM) field experiments are receiving growing scientific and policy attention, with several localized experiments having occurred or under development. While they may be critical for improving technical understanding and reducing uncertainties, SRM field experiments remain controversial and inadequately ...
