AGU Advances, 2023 Studies of the impacts of solar geoengineering have mostly ignored tropospheric chemistry. By decreasing the sunlight reaching Earth's surface, geoengineering may help mitigate anthropogenic climate change, but changing sunlight also alters the rates of ...

Arctic Sea Ice Decline and Geoengineering Solutions: Cascading Security and Ethical Considerations
Challenges, 2022 Climate change is generating sufficient risk for nation-states and citizens throughout the Arctic to warrant potentially radical geoengineering solutions.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Dry‐wet whiplash events profoundly impact society and the environment, yet their attribution remain poorly understood. This study reveals that the unprecedented interannual wet‐to‐dry transition (return period: 979.2 years) in South China's 1962–1963 pre‐flood season is co‐driven by internal variability and volcanic forcing.

Implications of geoengineering under the 1.5 °C target: Analysis and policy suggestions
Advances in Climate Change Research, 2017 The Paris Agreement introduced a 1.5 °C target to control the rise in global temperature, but clear arrangements for feasible implementation pathways were not made.

Halving warming with stratospheric aerosol geoengineering moderates policy-relevant climate hazards
Environmental Research Letters, 2020 Stratospheric aerosol geoengineering is a proposal to artificially thicken the layer of reflective aerosols in the stratosphere and it is hoped that this may offer a means of reducing average climate changes.

Maximum Lifetime of the Vegetative Biosphere
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.Abstract We use a three‐dimensional model to calculate steady‐state climates at various intervals in Earth's future, across a parameter space of increasing insolation and decreasing CO2 ${\text{CO}}_{2}$ mixing ratio. Comparison with prior results shows an overestimation of warming by one‐dimensional models when solar constant is increased and CO2 ...

Sulfur Exposure for Airplane Passengers From Stratospheric Aerosol Injection
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Injection of sulfur dioxide to create a stratospheric sulfate aerosol cloud is the most studied method of climate intervention. It has been suggested that airplanes be used at high latitudes to create such a cloud at lower altitudes. Commercial airplanes routinely fly at altitudes of 11 km in the Arctic, and therefore passengers could be ...

Heliotropic dust rings for Earth climate engineering
, 2013 This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth's J(2) oblateness ...

Geoengineering: Symmetric precaution [PDF]
Science, 2021 As alarm about climate change and calls for action intensify, solar geoengineering (SG) is seeing increased attention and controversy. Views on whether it should or will ever be used diverge, but the evidentiary basis for these views is thin. On such a high-stakes, knowledge-limited issue, one might expect strong support for research, but even research

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.
