Climate geographies and geographies of knowledge

Abstract Focusing on ‘Geographies of Knowledge’, this Commentary explores interactions between knowledge about climate change and the evolving multi‐level governance of climate. Three vignettes illustrate the complexity of this relationship. The first shows how expert advice, combined with other factors, persuaded the UK government to adopt an ambitious, long‐term emissions reduction target in the early 2000s. The second considers the ‘2°C target’ (latterly 1.5°C) to limit rises in global mean temperature, variously seen as essential, unachievable or symbolic. The third turns to geoengineering and its governance. All three demonstrate the significance of epistemic, political and discursive factors, as these intertwine and play out across different sites, scales and levels of governance.
