Geoengineering to save the Arctic?

2026

Abstract

Geoengineering efforts often target the Arctic due to its crucial role in the global climate system. However, geoengineering is highly controversial in scientific communities and society. Here we offer a crossdisciplinary perspective focused on science, governance, ethics, and the inclusion of rights-holders in the Arctic, collected in the context of an International Arctic Science Committee cross-cutting activity. The purpose of this article is to alert the science community to the urgency of the issue and provide suggestions on ways forward to make Arctic geoengineering research robust and ready to support policymaking.

Climate engineering

Climate engineering (also called geoengineering) is a term used for both carbon dioxide removal and solar radiation management, also called solar geoengineering, when applied at a planetary scale. However, they have very different geophysical characteristics which is why the Intergovernmental Panel on Climate Change no longer uses this overarching term. Carbon dioxide removal approaches are part of climate change mitigation. Solar geoengineering involves reflecting some sunlight (solar radiation) back to space.

Climate change

In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane.

Solar geoengineering

Solar geoengineering, or solar radiation modification (SRM), is a type of climate engineering in which sunlight (solar radiation) would be reflected back to outer space to limit or offset human-caused climate change. There are multiple potential approaches, with stratospheric aerosol injection (SAI) being the most-studied method, followed by marine cloud brightening (MCB). Other methods have been proposed, including a variety of space-based approaches, but they are generally considered less viable, and are not taken seriously by the Intergovernmental Panel on Climate Change.
