May 2025 spell climate hope after a super-warm 2024

Let's harness the negativity bias that humans are predisposed to for measures aimed at faster climate action

As 2024 came to an end, a number of alarming articles were published in various global and national media outlets about 2024 being the hottest year on record, the disastrous impact of extreme weather events due to climate change, the need to enhance climate action in the face of contentious climate negotiations in Azerbaijan and an American election that did not bode well for the climate agenda, among others.

All these concerns are valid and need immediate attention. However, several other articles highlighted positive developments related to the groundwork being laid for a potential transition away from fossil fuels, notably the explosion of affordable and accessible renewable energy, the rapid growth of electric vehicles, the falling costs of battery storage, big moves away from coal, etc. But these articles provided little solace. The sense of foreboding around climate change was palpable, primarily because of the contrast between widely published real-time data and the highly visible impact of extreme events across the world and the perceptibly slow evolution of a subset of solutions that may take years to reach a take-off point.

The human mind is predisposed to a negativity bias—a cognitive bias that recognizes and responds to negative events with greater sensitivity than when positive or neutral things of equal intensity occur—which has been well established for at least half a century. This bias is abundantly visible in discussions on climate change and its impacts, fed by the same dread visible in some news reportage and on social media. This bias, however, must be positively harnessed.
