Visitors are increasingly drawn to disappearing glacier landscapes for their beauty and scientific value. This Comment examines the paradoxes reshaping relationships among glaciers, people and communities, and highlights research needed to avoid maladaptation harming local communities.

Climate change drives displacement and migration across the Americas, particularly exposing Latin American and Caribbean children to compounded health risks. We explore these health impacts, identify gaps in related US healthcare and health policy, and propose recommendations for how they can respond.

Transforming school environments into nature-based climate shelters not only promotes cooling and greening under extreme heat, but also fosters quality education, ecological restoration, empowerment and reconnection with nature, and provides children with healthier, safer, more playful, equitable and climate-proof spaces.

Mountains, with their sharp climatic contrasts, are emblematic of climate-driven species movement and, ultimately, loss. Here, we argue that these same contrasts make mountains powerful natural laboratories for discovering the mechanisms that underlie biological change.

Mountains and their ecosystems have been important to religious beliefs in many regions around the world. In this Viewpoint, researchers describe how climate change in mountain regions is interpreted by local communities and how they transform their spiritual practice in response to it.

It is essential to understand the best way to frame a persuasive message aimed at increasing concern about climate change and support for pro-environmental action. Now a Registered Report presents a large-scale study that tests and compares the effectiveness of ten widely cited messaging strategies.

A spatial assessment of global decarbonization scenarios reveals that land allocated for carbon dioxide removal substantially overlaps with areas of high biodiversity importance. The implications of such overlap depend on location and mode of implementation and demonstrate that careful assessment will be required when implementing decarbonization pathways to safeguard biodiversity.

A Europe-wide probabilistic assessment of coastal flood risk to road and rail infrastructure, at different levels of global warming, shows that each increment of warming amplifies flood damage. Smaller economies face the greatest relative economic impacts, and several countries will need to increase and potentially realign transport investments towards climate resilience.

Mountains are hotspots of climate change, with melting glaciers, changing water flows and moving ecosystems. Here the authors discuss how these different changes in mountain regions affect downstream regions.

Many mountain glaciers will disappear with warming. Here the authors assess how many glaciers will disappear per year under different warming scenarios, finding that a peak in glacier loss will happen during the mid-twenty-first century.

The El Niño–Southern Oscillation threatens human health, and its impacts are likely to intensify under climate change. This research examines how historical El Niño–Southern Oscillation events have caused life expectancy and economic losses across the Pacific Rim and projects future impacts and vulnerable groups.

Carbon dioxide removal (CDR) plays an important role in decarbonization pathways to meet climate goals, but some methods are land-intensive. Multimodel analysis reveals conflicts between biodiversity and CDR that are distributed unevenly, and shows that synergies are crucial to meet climate and conservation goals.

Reducing the embodied carbon emissions of building material stock is essential for mitigation. Using a high-resolution multiyear dataset in China, researchers show the historically massive contributions of these emissions during past decades of rapid urbanization and the potential risks for future climate goals.

Transport networks in coastal zones are critical for human activities and are faced with increasing flooding risk. Using a detailed risk analysis in Europe, the authors show that the affected networks and expected annual damage will increase considerably with global warming.

The Atlantic Ocean is having an increasing influence on the Arctic but the drivers of this are unclear. By combining ocean modelling and deep learning methods, the authors show that the increased flow through the Barents Sea Opening is driven by spectral changes of atmospheric variability.

More frequent fires in the North American boreal are causing shifts from conifer to deciduous forests. This study finds that when deciduous forests burn, their carbon losses are driven by weather, but are lower than in conifer forests, potentially dampening climate–fire feedbacks.

The authors quantify long-term (2003–2024) changes in Northern Hemisphere mountain aspect asymmetry—the difference in vegetation density between polar-facing and equatorial-facing slopes. They show a weakening trend, linked to changing hydrothermal conditions.

The authors consider the changing sensitivity of the leaf-onset date to temperature (S_T) for boreal deciduous broadleaf forests. S_T increased between 1982–1996 and 1998–2012—potentially linked to enhanced chilling accumulation—but this increase is underestimated in phenology models.

In addition to affecting general economic indicators, climate change could worsen poverty and inequality across and within countries. With a global subnational dataset, researchers confirm that temperature rise leads to increases in headcount poverty and the Gini index, with poorer countries being particularly vulnerable.

How to effectively communicate climate change to the public has long been studied and debated. Through a registered report megastudy, researchers tested the ten most-cited climate change messaging strategies published, finding that many had significant, but small, effects on climate change attitudes.
