Reviews & Analysis

This Perspective evaluates efforts using machine learning to track global progress on adaptation, focusing on recent efforts in text analysis. It discusses practical and theoretical challenges, lessons learned and ways forward. It urges the adaptation community to prepare for a paradigm shift.

Both warming and precipitation changes are affecting the global carbon cycle, although the impact of the frequency and intensity of climate extremes on carbon cycling is unclear. Now, research suggests that most extreme events enhance soil organic carbon losses under warming globally.

The shale gas revolution has provided a cheap and relatively clean alternative for coal, but it also threatens the future market for renewables. Recent projections indicate that without tightening climate policy, shale gas will indefinitely delay the transition to net zero.

The Madden–Julian Oscillation (MJO), a large storm system over the Indian Ocean and Western Pacific, plays a crucial role in our ability to forecast Earth’s weather 2–4 weeks in advance. Now, research suggests that the predictability of the MJO itself is increasing and will continue to increase with global warming.

Underlying net-zero GHG accounting approaches is the assumption that emissions can be balanced by removals such that their net climate effect is zero. However, CO₂ removals may not be equal and opposite to CO₂ emissions in their climate impact, indicating the need to consider non-CO₂ effects.

Fire severity is expected to increase as a result of warming. This will potentially amplify climate change due to its impact on the carbon cycle. This Review discusses ecosystem carbon loss and recovery following wildfire, and highlights where further work is needed to inform model predictions.

Funding large-scale negative emissions through a carbon market designed for traditional emission reduction strategies risks exacerbating long-term economic inequality. We suggest exploring alternative financing mechanisms that address this concern and that still ensure decarbonization at reasonable costs.

Neuroscience can help combat climate change by studying its impact on the human brain, adaptation strategies, decision-making processes and communication strategies. This Perspective outlines a roadmap towards these targets and calls on neuroscientists to join the fight against this global threat.

Aerial photographs collected during mapping expeditions of Greenland’s coastline represent the only robust, widespread observations of twentieth-century glacier change for this vast island. We use this unique dataset to document the response of Greenland’s peripheral glaciers to climate change over approximately 130 years, providing enhanced confidence that recent changes are exceptional on a century timescale.

The global loss and damage fund is essential to provide support for climate-impacted groups and help their local initiatives for adaptation. Now, research focusing on the Vanuatu population highlights the necessity to put human rights as a central consideration for loss and damage fund agendas.

Concrete analysis of job impacts is needed to inform efforts for a just transition. Now, a study finds that decarbonizing US electricity generation will create jobs, but with uneven distribution among states, industrial sectors and skill needs.

The remaining carbon budget for 1.5 °C has been a highly discussed tool to communicate the urgency of efforts needed to meet the Paris Agreement. Now, research reassesses IPCC estimates, suggesting that ongoing near-flat emissions and methodological choices can make big relative differences to the tiny remaining 1.5 °C budget.

Global warming and overfishing are impacting fish species distribution, total catch and aquaculture viability, limiting our ability to harvest vital micronutrients that support human health.

Nature-based solutions are essential to avoid climate crisis, yet how best to estimate their long-run effects is unclear. Here the authors propose a new dynamic accounting method that captures the impermanence of these carbon impacts, allowing investors to make robust comparisons across projects.

The collapse of the West Antarctic Ice Sheet is a worrying climate tipping point, with the potential to raise global sea level by up to 5.3 metres. Now, an assessment of future climate scenarios suggests that accelerated melting of ice shelves in West Antarctica is locked in, even for the most ambitious emissions reduction scenarios.

Assessing progress and gaps in climate adaptation is a key policy concern, and also raises scientific challenges around which metrics should be used and who should assess progress. A structured expert judgement using local case studies shows that, for coastal areas, today’s global adaptation is halfway to achieving the full adaptation potential.

Over the past years, countries in Latin America and the Caribbean have seen a range of developments around climate mitigation and environmental policy. Nature Climate Change asked a selection of scientists from the region to share their thoughts on research questions and responses to climate change in their area of study.

In this Perspective, the authors highlight agroforestry as a natural climate solution, discussing definitional refinements, controls on mitigation potential and remote sensing innovations. They assess the status of agroforestry in the context of climate ambitions, identifying key areas and opportunities.

Establishment of the loss and damage fund is a major step in climate negotiations for Global South countries, yet resource allocation remains unsettled. This Review shows how vulnerability-based approaches are variable and complex, with the adoption of quantitative measures likely to bring division.
