Abstract english
Solar Radiation Modification (SRM) can neither conserve the current nor restore the pre-industrial climate. It would create an unpredictable new global climate with significant regional impacts. This brochure explains the risks of SRM for food security, justice and actual climate action. It explains the various SRM approaches and how they are supposed to work. It also describes the state of regulation and formulates conditions for responsible governance, including a non-use agreement.

Durch Solar Radiation Modification (SRM) kann weder das bisherige Klima konserviert, noch das vorindustrielle Klima wiederhergestellt werden. Es würde ein unvorhersagbares, neues Klima mit erheblichen regionalen Auswirkungen entstehen. In dieser Broschüre werden die Risiken von SRM für Ernährungssicherheit, Gerechtigkeit und echten Klimaschutz erläutert. Die verschiedenen Ansätze und deren Wirkweise werden erklärt. Zudem wird die rechtliche Ausgangslage beschrieben und Bedingungen für eine verantwortliche Governance, einschließlich eines Nicht-Nutzungs-Abkommens, formuliert.

Poster: Risks of Solar Radiation Modification (SRM)
(2024)
SRM is supposed to mask global warming by enhancing the earth’s albedo, for example by stratospheric aerosol injection. Thus altering the whole climate system, SRM would impact most areas of life. The risks for geopolitics, mitigation deterrence, ecosystems, justice, food security and water availability are illustrated in this graphic.
