Large animal conservation and rewilding are increasingly considered to be viable climate mitigation strategies. We argue that overstating animal roles in carbon capture may hinder, rather than facilitate, effective climate mitigation and conservation efforts.
US healthcare contributes 8.5% of national greenhouse gas emissions, but its policies to guide mitigation and waste reduction are underdeveloped. We recommend national policies to streamline the adoption of best practices, address implementation challenges to achieve net-zero goals and serve as useful exemplars for other nations.
From a scientific standpoint, the causes of current ongoing climate change are well established. But in the context of rapid change, and real-world consequences, there is still room — and need — for scientific discussion in climate change fields.
Climate impacts are triggering a host of novel bio- and geoengineering interventions to save coral reefs. This Comment challenges heroic scientific assumptions and advocates for a more systemic, evidence-based approach to caring for coral reefs.
Reef-building corals are declining globally, putting important ecosystem services at risk. Here we discuss the potential risks and benefits of coral ecological replacement, in which new species are introduced to replace the functional roles of species that have declined or disappeared.
Coral reefs are at risk from ongoing climate change. We can best serve the reefs by invoking realistic scenarios, empiricism, artificial intelligence and falsification to self-correct the current scientific limits that hinder climate science predictions, communication and policies.
Currently, no comprehensive scientific methodology of corporate risk quantification, in response to new disclosure regulations, has been proposed in the literature. Here we develop fundamental principles that are important for the appropriate use of climate scenario science in transition risk assessments.
Projections of the future climate of small island states and territories are currently limited by the coarse resolution of models. We call for rapid global and regional cooperation to develop projections compatible with small island scales, providing relevant local information and decision-making tools.
Small island states and territories have been leading climate action in many ways. In this issue, we highlight climate change research conducted on large ocean islands and how science can improve to help them adapt to changing environments.
Adaptation evidence and knowledge are diverse and unequally represented in global adaptation discourse. The Adaptation Futures 2023 conference sought to bring this diversity together to advance more inclusive and impactful adaptation science, and confronted both the benefits and the trade-offs that this effort entails.
To accept carbon pricing, citizens desire viable alternatives to fossil fuel-based options. As inflation and higher interest rates have exacerbated access barriers for capital-intensive green substitutes, the political success of carbon pricing will be measured by how well policy design enables consumers to switch.
