The 28th Conference of the Parties (COP) taking place in Dubai from 30 November to 12 December 2023 will focus heavily on the first of the Global Stocktakes that were agreed upon in the Paris Agreement. In this infographic, we explain what the Global Stocktake is, how it works and the different interests and sticking points that are expected to shape the debate at COP28.

Climate emotions permeate student learning and research activities, but their influence is poorly understood and often ignored in higher education. We develop recommendations for instructors, research mentors and institutional leaders to enhance educational and research outcomes for students grappling with challenging climate emotions.

Climate change education is crucial to countries in the Global South due to their contribution and vulnerability to the climate crisis. However, institutionalizing and implementing climate change education is particularly challenging in developing nations, given inadequate motivation and limited capacity.

Climate education is seen as a key driver for behavioural change, yet it is usually not continued universally to higher-education level. With the increasing demand from both students and employers, we propose methods that incorporate climate education from multiple disciplines into current curriculums.

Climate models have evolved from research tools to underpin decision-making across the globe. To provide optimal value for society in the future, the models need to be made operational.

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 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.

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.

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.

A multi-model analysis shows that the incorporation of advances in damage functions — namely growth effects — substantially increases the social cost estimates of methane and nitrous oxide, although uncertainty remains.

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.

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.

Protest plays an essential role in promoting climate actions, yet individual participation decisions are influenced by expectations about other people’s attendance. This study displays evidence on strategic substitutability, that is, respondents are less motivated if they expect high turnout.

The low-carbon transition would bring both challenges and opportunities for the labour market, which have important implications for a just transition. In the US power system, the lowest-skilled workers in fossil fuel-dependent states will face more uncertain employment and job training will be necessary.

Assessing adaptation progress is key to reducing risk associated with climate change, yet the status of adaptation in most sectors is unclear. This study assesses the state of coastal adaptation globally and finds that current efforts fulfil about half of the total potential.

The authors use a regional ocean model to project ocean-driven ice-shelf melt in the Amundsen Sea. Already committed rapid ocean warming drives increased melt, regardless of emission scenario, suggesting extensive ice loss from West Antarctica.

Projections of ocean heat transport show a decrease which is driven by a decline in overturning circulation. Such a decrease in ocean heat transport can dampen the global warming signal in Northwest Europe.

Changes in air temperature are usually considered for quantifying changes in temperature extremes such as heatwaves. This study shows that the incidence of heat extremes in soils is increasing faster than air temperature in some regions, with implications for hydrological and biogeochemical processes.

The authors use fisheries databases and predictive models to understand past and future changes in the availability of iron, calcium omega-3 and protein from seafood. They show disproportional loss of nutrients in tropical low-income countries, which will be exacerbated by higher levels of global warming.

For global adaptation effort, it is essential to understand which actors are participating and what their roles are. This Analysis, based on comparative case studies, displays the dominant actors in adaptation, and how the actor–role patterns vary across regions.

Non-CO₂ emissions, including methane and nitrous oxide, are non-negligible contributors to global warming. A multimodel analysis incorporating recent advances in damage functions shows that the social cost of these greenhouse gases would increase substantially, although uncertainty remains.

To test the reproducibility of ocean acidification research, the authors conducted a meta-analysis of 373 studies on calcification of marine calcifiers across 24 years. While the size of negative effects declined over time, the results remained reproducible and their limitations were then explored.
