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.

Youth co-authorship as public engagement with geoengineering [PDF]

, 2022
Large-scale intervention in the Earth’s climate system (‘geoengineering’ or ‘climate engineering’) is increasingly present in discussions about possible responses to climate change.

Quantifying the Effectiveness of Multiple SAI Strategies Across Different Dimensions

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Stratospheric aerosol injection (SAI) modeling experiments are often designed to keep global mean surface air temperature (GMSAT) close to a reference target, such as early‐century SSP2‐4.5. However, meeting this target does not necessarily restore regional climates or the seasonal and spatial patterns of key variables.

The Morals of Model-Making [PDF]

, 2013
I address questions about values in model-making in engineering, specifically: Might the role of values be attributable solely to interests involved in specifying and using the model? Selected examples illustrate the surprisingly wide variety of things

Reductions in Climate Zone Changes Under Stratospheric Aerosol Injection Compared to Unabated Warming

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract As the goals of the Paris Agreement struggle to be met, interest in stratospheric aerosol injection (SAI) has increased due to its potential to reduce the impacts of anthropogenic warming. SAI would aim to cool the Earth by injecting sulfate aerosols or their precursors into the stratosphere, reflecting incoming sunlight back to space ...

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

Land Radiative Management Increases Heat Stress in Some Humid Regions

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Heat stress may exceed human physiological limits this century in hot and humid regions. Land radiative management (LRM), a geoengineering strategy that increases surface albedo, aims to reduce heat stress. However, previous work has shown that LRM suppresses rainfall in surrounding regions, drying soils and increasing temperatures.

Distributive Justice, Geoengineering and Risks [PDF]

, 2014
It is generally recognised that the potential positive and negative impacts of geoengineering will be distributed unevenly both geographically and temporally.

Wind‐Driven Circulation Feedbacks Offset Tropical Geoengineered Sea Salt Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Using a NOAA Geophysical Fluid Dynamics Laboratory coupled atmosphere–ocean (CM4) comprehensive model, we employ simulations of enhanced, geoengineered sea salt aerosol (SSA) emissions in the tropics to examine the circulation response to idealized marine cloud brightening. Increased tropical SSA emissions cool the deployment region and weaken

Impacts of hemispheric solar geoengineering on tropical cyclone frequency [PDF]

, 2017
Solar geoengineering refers to a range of proposed methods for counteracting global warming by artificially reducing sunlight at Earth’s surface. The most widely known SG proposal is stratospheric aerosol injection (SAI) which has impacts analogous to ...
