Climate change can have profound impacts on mental health, yet few therapists receive training on how to talk to their clients about this issue. This Comment explores strategies for therapists to best support clients in climate distress.

Recent policy progress in the United States shows how populism can help advance climate goals, but at a steep cost. Avoiding setbacks will require curbing protectionist reflexes and harnessing opportunities for global cooperation.

Last December saw the inaugural Health Day at a Climate Conference of the Parties (COP) and the announcement of the COP28 UAE Declaration on Climate and Health, marking a substantial step in global recognition of the intersecting crises of climate change and health. Nature Climate Change speaks to Maria Neira, director of the Department of Environment, Climate Change and Health at the World Health Organization, about successes and next steps.

Climate change is a health emergency, impacting multiple facets of human well-being via direct and indirect pathways. Nature Climate Change asked experts from different health fields to share their thoughts on the urgent issues and possible paths forward.

Scientists and health professionals acknowledge that climate change is also a health emergency, but responses have been slow. Now, citizens and experts are turning to the courts as a path towards accountability, action and adaptation.

Residents of informal settlements suffer from extreme weather due to their precarious living environment. Now, findings show that extreme weather event thresholds do not fully capture the negative impacts experienced by women in Nairobi, Kenya.

International cooperation is essential to mitigate climate change, yet it comes with challenges that often hinder countries from achieving their climate targets. Now, a study shows that timely monitoring and review of national climate mitigation efforts are essential for the Paris Agreement to accomplish its targets.

As climate change redirects migration patterns of marine species towards the extremes of their geographic range, sharks find themselves stunned by rising cold upwelling currents.

Current model-based financial regulations favour carbon-intensive investments. This is likely to disincentivize banks from investing in new low-carbon assets, impairing the transition to net zero. Financial regulators and policymakers should consider how this bias may impact financial system stability and broader societal objectives.

In this Perspective, the authors develop an integrated framework to understand and predict the joint impacts of climate change and urbanization on biodiversity and ecosystems. They review examples of interacting impacts and present opportunities for future research.

In this Perspective, the authors develop a risk assessment framework for forest microbiomes under climate change that unites microbial and forest ecology. They define processes that amplify or buffer microbial sensitivity and exposure risk and feedbacks that mediate impacts on microbial communities.

Defining thresholds for extreme weather events is important for adaptation but often ignores impacts on climate-vulnerable communities. This research finds current practices do not capture experiences of women in informal settlements and self-reported impact data could help to address the issue.

The 15th Conference of the Parties (COP15) in Copenhagen marked an important step in global climate action with parties submitting 2020 mitigation targets. However, this retrospective study shows that many countries either have failed to meet their targets or have reduced their emissions through carbon leakage.

As the financial system is increasingly important in catalysing the green transition, it is critical to assess the impediments it may face. This study shows that existing financial regulations may impair the shift of financial resources from high-carbon to low-carbon assets.

Climate change will affect the adoption of residential rooftop solar photovoltaics by changing the patterns of both electricity generation and demand. This research projects that climate change will increase the future value and optimal capacity of household rooftop solar across the United States.

Rapid population ageing is challenging for climate adaptation. Considering ageing demographics and green infrastructure development in 26,885 Southeast Asian communities, the authors find a reduction in green space in ageing communities, especially in socio-economically disadvantaged areas, with implications for vulnerability.

How the climate system changes under negative emissions is not well known. Here the authors show that the mid-latitude storm tracks change in an asymmetric way, leading to stronger Northern Hemisphere and weaker Southern Hemisphere storm tracks after recovery to present-day CO₂ concentrations.

The degree to which changes in marine organisms due to warming can influence tropical cyclones is not well known. Here the authors show that changing chlorophyll patterns can lead to more landfalling tropical cyclones in East Asia.

Using a global meta-analysis approach, the authors show that elevated CO₂ alone can increase primary productivity and leaf C/N ratio and stimulate nitrogen fixation and nitrogen use efficiency. They project increasing carbon sink and decreasing reactive nitrogen loss under climate change.

The authors use resurrected strains of a diatom species to compare temperature optima, cell size and gene expression across 60 years. Modern samples have a 1 °C higher temperature optima and probably support increased nutrient uptake, highlighting the adaptation potential of diatoms to global change.

The authors link intensification of cold upwelling in two western boundary currents to the observed death of marine organisms, and upwelling avoidance behaviour in bull sharks. They raise concerns of increased risk of cold-mortality events for climate migrants at their poleward distribution limits.

The authors perform a meta-analysis to assess current and future capacities of healthcare systems under climate change. They summarize the key focus points of current literature and highlight the need for effective policies, trained workforces and redesigned infrastructure to meet future burdens.
