‘It’s just a Band-Aid!’: Public engagement with geoengineering and the politics of the climate crisis

Geoengineering consists of a set of techniques whose aim is to avoid the disastrous consequences of global warming, such as solar radiation management and carbon dioxide removal. Due to its controversial nature, over the past decade various exercises of public participation with geoengineering have been put in place, particularly in the Global North. This article draws on empirical data stemming from six online focus groups on public engagement with geoengineering conducted in Portugal. In contrast to previous research, we included situated publics to emphasize the political implications of geoengineering, bringing to the debate those with a potential stake in the matter – environmentalists, activists, university students, science communicators and promoters of holistic practices. We suggest that the elusive and uncertain character of geoengineering moves the discussion away from its technological specificity, bringing to the fore some of the socio-political, economic and ethical tensions underpinning the climate crisis.
