Shallowing Southern Ocean aragonite

The aragonite saturation horizon depth is an indicator of ocean acidification. Model projections show the emergence of a shallow horizon in the near future in the Southern Ocean, reducing the suitable habitat for surface-dwelling aragonitic organisms, such as the pteropod illustrated on the cover.

    Men and women differ in their perceptions of environmental risk, vulnerability to climate change impacts and adaptation behaviour. Effective policies must address the diversity of gender roles and identities, and the underlying drivers of inequality.

Research Highlights

    Women have typically been excluded from forest conservation programs due to traditional decision-making structures in their villages and local governments. Research now shows that greater representation of women in forest-user groups leads to more equitable sharing of program benefits and increases conservation outcomes.

    The Arctic climate is changing rapidly, but quantifying outcomes for Inuit has been elusive. Now, research starts with trail-use instead of models, and finds that the effects from climate change are modest compared with the role of skill and risk-tolerance of the travellers.

    Emergent constraints can be an evaluation tool for Earth System Models. This Perspective discusses emergent constraints, how they should be assessed, and when these statistical relationships can be confirmed and used to improve understanding of the changing climate system.

Review Articles

    Cities around the world are at the forefront of enacting climate mitigation policies, but effective action requires a better understanding of potential solutions. This Review offers a systematic exploration of the urban case study literature and discusses ways to best make use of the growing body of cases.

    Decision-making structures in forest-user communities often exclude women. This lab-in-field experiment shows that groups in which at least 50% of members were women conserved more trees, and distributed benefits more equally, in a payment for ecosystem services intervention.

    Climate change has the potential to profoundly affect Arctic transportation systems. Here, Indigenous knowledge and climate data are integrated to model changing trail access for Canada’s Inuit communities over the past 30 years
