Climate change is a politically polarized subject, and changing peoples’ beliefs is challenging. This study shows that participation in a climate prediction market by betting on future climate outcomes may be an effective way to change both attitudes and behaviour around climate change.

Economists often dominate public climate policy discussions, such as those on the proper social discount rate and optimal climate pathways. This Article shows that philosophers, experts in underlying ethical matters, generally agree with economists but put more weight on various normative considerations.

The authors show that estuarine and coastal vegetation are collectively a greenhouse gas (GHG) sink for the atmosphere, but methane and nitrous oxide emissions counteract the carbon dioxide uptake. Critical coastal GHG sink hotspots are identified in Southeast Asia, North America and Africa.

Achieving global carbon neutrality will lead to a low-warming future and impact renewable energy production. This study demonstrates that deep mitigation pathways can bring positive feedback that enhances and stabilizes solar and wind energy production.

The drivers of uncertainties in hydrological sensitivity, the global-mean precipitation response to warming, are currently not well understood. Here the authors show that the spatial pattern of sea surface temperature warming explains much of this uncertainty and could allow to constrain projections.

In contrast to the overall recovery of stratospheric ozone, ozone depletion in the tropical lower stratosphere has been ongoing over recent years. Here the authors show that currently unregulated halogenated ozone-depleting very short-lived substances play a key role in this ongoing depletion.

Antarctic bottom water (AABW), a key component of ocean circulation, provides oxygen to the deep ocean. This work shows that AABW transport reduced over the past decades in the Australian Antarctic Basin, weakening the abyssal overturning circulation and decreasing deep ocean oxygen.

Large language models offer an opportunity to advance climate and sustainability research. We believe that a focus on regulation and validation of generative artificial intelligence models would provide more benefits to society than a halt in development.
