Carbon dioxide removal is rapidly becoming a key focus in climate research and politics.
This is raising concerns of “moral hazard” or “mitigation deterrence,” that is, the risk that …

Current mitigation efforts and existing future commitments are inadequate to accomplish the
Paris Agreement temperature goals. In light of this, research and debate are intensifying on …

The impacts of global climate change on international security and geopolitics could be of
historic proportion, challenging those of previous global threats such as nuclear weapons …

Solar geoengineering refers to deliberately reducing net radiative forcing by reflecting some
sunlight back to space, in order to reduce anthropogenic climate changes; a possible such …

Solar geoengineering is receiving increased policy attention as a potential tool to offset
climate warming. While climate responses to geoengineering have been studied in detail …

Although solar geoengineering (alternatively 'solar radiation management'or 'solar radiation
modification') appears to offer a potentially effective, inexpensive and technologically …

Geoengineering options such as negative emissions technologies (NETs) or greenhouse
gas removal (GGR) may need to contribute towards decarbonization, by removing CO 2 from …

Injecting particles into atmosphere to reflect sunlight, stratospheric aerosol injection (SAI),
represents a potential technological solution to the threat of climate change. But could the …

The scientific literature on the co-impacts of low-carbon energy systems—positive and
negative side effects—has focused intently on climate mitigation, or climate adaptation. It …

Geoengineering technologies aim to make large-scale and deliberate interventions in the
climate system possible. A typical framing is that researchers are exploring a 'Plan B'in case …
