Non-technical summary We summarize what we assess as the past year's most important findings within climate change research: limits to adaptation, vulnerability hotspots, new threats coming from the climate–health nexus, climate (im)mobility and security, sustainable practices for land use and finance, losses and damages, inclusive societal climate decisions and ways to overcome structural barriers to accelerate mitigation and limit global warming to below 2°C. Technical summary We synthesize 10 topics within climate research where there have been significant advances or emerging scientific consensus since January 2021. The selection of these insights was based on input from an international open call with broad disciplinary scope. Findings concern: (1) new aspects of soft and hard limits to adaptation; (2) the emergence of regional vulnerability hotspots from climate impacts and human vulnerability; (3) new threats on the climate–health horizon – some involving plants and animals; (4) climate (im)mobility and the need for anticipatory action; (5) security and climate; (6) sustainable land management as a prerequisite to land-based solutions; (7) sustainable finance practices in the private sector and the need for political guidance; (8) the urgent planetary imperative for addressing losses and damages; (9) inclusive societal choices for climate-resilient development and (10) how to overcome barriers to accelerate mitigation and limit global warming to below 2°C. Social media summary Science has evidence on barriers to mitigation and how to overcome them to avoid limits to adaptation across multiple fields.

“…From an obstetric point of view, it is also very important to underline that climate change will directly influence not only pregnancy outcomes but also fertility itself. An elevated ambient temperature may lead to more pre-term births, a low birth weight, stillbirth, and gestational diabetes in mothers [ 45 ]. Heat shock may affect reproductive tissues mostly by oxidative stress and unregulated production of free radicals, reactive oxygen species, and reactive nitrogen species.…”

Antinatalism is an umbrella term for numerous moral dilemmas associated with procreation. In the past few years, the deterioration of environmental conditions, social difficulties, global worsening of people’s mental health, and pandemics have induced discussion about antinatalism. Therefore, we aimed to characterize antinatalists in the Polish population in terms of the frequency and description of the main reasons behind this phenomenon. The cross-sectional study was performed in the Polish population. An online, four-part survey was performed between 19 and 25 January 2022. The study group comprised 1240 respondents. Antinatalists (n = 472, 38%) were defined as people who do not have children and want to be childless in the future, whereas pronatalists (n = 768, 62%) consisted of people who want to have offspring in the future and/or already have children. The opinion that climate change is a significant reason not to have a child appeared twice as often among antinatalists. Additionally, the performed binary logistic regression model highlighted the importance of the fear of climate change as an independent factor facilitating an antinatalistic attitude. Regarding females, the following factors discouraging them from having a child were observed: fear of child’s congenital diseases, pregnancy complications, dissatisfaction with medical services, and fear of exacerbation of maternal chronic diseases. Anxiety, depression, and stress were not found to be statistically different between pro- and antinatalist groups. However, further analysis revealed that female antinatalists were significantly more depressive and anxious. Our study helps us to understand why, as mentioned beforehand, around 38% of respondents prefer to stay childless. In conclusion, antinatalism views have become relatively prevalent in society, and its reasons include environmental antinatalism and medical factors, including depression and anxiety. However, better access to medical services and changes in climate politics were not found to be significant factors in encouraging society to decide to have offspring.

“…In addition, maternal stress can lead to changes in placental gene expression and modifications in the fetus's endocrine and immune environment, affecting the child's asthma development [15]. In the case of elevated ambient temperatures, the changes in placental perfusion, nutrient exchange, and oxygen delivery, added to increased oxidative stress, cytokines, and other inflammatory markers released during heat exposure, can affect fetal growth and impair weight gain [16,17]. A recent meta-analysis reported a 16% higher risk of PTB and a 9% higher risk of LBW with increased exposure to elevated temperature [18].…”

Purpose of reviewTo date, there is no evidence that humanity will implement appropriate mitigation measures to avoid the catastrophic impact of climate change on the planet and human health. Vulnerable populations such as pregnant women and children will be the most affected. This review highlights epidemiologic data on climate change-related prenatal environmental exposures affecting the fetus and children's respiratory health.Recent findingsResearch on outcomes of prenatal exposure to climate change-related environmental changes and pediatric pulmonary health is limited. In addition to adverse pregnancy outcomes known to affect lung development, changes in lung function, increased prevalence of wheezing, atopy, and respiratory infections have been associated with prenatal exposure to increased temperatures, air pollution, and maternal stress. The mechanisms behind these changes are ill-defined, although oxidative stress, impaired placental functioning, and epigenetic modifications have been observed. However, the long-term impact of these changes remains unknown.SummaryThe detrimental impact of the climate crisis on pediatric respiratory health begins before birth, highlighting the inherent vulnerability of pregnant women and children. Research and advocacy, along with mitigation and adaptation measures, must be implemented to protect pregnant women and children, the most affected but the least responsible for the climate crisis.
