The value of unrealistic targets: why some climate activists are unwilling to abandon the 1.5 °C target

Abstract

Evidence is mounting that the 1.5 °C goal of the Paris Agreement is unrealistic. But, contrary to many in the scientific community, major NGOs have remained steadfast in their support for this target. We argue that this is because “unrealistic” or aspirational targets can serve important political objectives, including becoming focal points for coalition-building and broad-based mobilization and allowing for effective naming and shaming.
