In a Review, Tiffany Morrison and colleagues discuss the risks associated with rapidly emerging marine-climate intervention approaches. Because current governance systems are ill-suited to the scale and novelty of these new interventions, the authors argue, new regulatory frameworks are urgently needed to balance risk and reward, avoid harm, and ensure that ocean-based climate solutions are safe, equitable, and effective. Rapid climate-driven changes are occurring in marine ecosystems worldwide. As a result, a range of new marine-climate interventions have been proposed, ranging from anthropogenically enhancing ocean alkalinity, to removing carbon dioxide from the atmosphere, to using assisted gene flow to breed heat-resistant corals. However, while many of these strategies inspire optimism, they are largely untested and pose unprecedented governance challenges. Here, Morrison et al. argue that the pace of new interventions is eclipsing the capacity of current governance systems and without careful oversight, these strategies may instead lead to unintended or irreversible harm. According to the authors, governance of marine-climate interventions must go beyond technical plans and public approval and should consider environmental, ethical, and political impacts, especially when projects are carried out on a large scale. While some early-stage guidelines exist, they have yet to be fully integrated into broader governance frameworks. The authors note that this lack of coordination slows progress toward achieving global marine and climate goals. To move forward, Morrison et al. advocate for dynamic governance principles that support “responsible marine transformation.” “There is mounting evidence that responsible transformation principles, if applied, can improve social, equity, and biodiversity outcomes and generate more durable ocean solutions,” write Morrison et al.

 

Arid and Semi-Arid Zones of Mexico: A Comprehensive Exploration of Biodiversity, Ecology, and Conservation is a multidisciplinary reference from Bentham Science Publishers that examines biodiversity, ecology, and conservation strategies across Mexico’s deserts.

The ongoing decline in ocean oxygen levels is intensifying due to climate change, significantly impacting marine ecosystems, including mesopelagic fish populations. This could disrupt marine food webs, fisheries, ocean health, and the ocean’s capacity to store carbon. 

A record six UNH faculty members have received prestigious Faculty Early Development, or CAREER, awards from the National Science Foundation. CAREER grants are the NSF’s premier awards in support of “early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organizations.”
