Article Synopsis
- The City of Cape Town has a plan for 2022-2027 to help the city deal with climate change and make it a better place to live.
- This plan includes priorities that aim to make sure everyone benefits from the city's developments, creating fair opportunities for all.
- By learning from this plan, other cities can also find ways to adapt to climate change and improve their communities.
The Southern Polar Region (Antarctica and the Southern Ocean) is threatened by climate change, and ocean warming and acidification. Reducing climate risks through direct human interventions in the region or through biological adaptation is not possible. Resilience of the region to global warming needs the establishment of climate refugia and science-based, climate-informed, ecosystem-based management, but long-term conservation will only be assured by global reduction in greenhouse gas emissions.

Materials And Methods: We utilised cross-sectional data from the Physical Activity and Nutrition in Children study (n = 230 to 396; 112 to 203 girls). Fat mass and BMC were assessed with dual-energy X-ray absorptiometry.
Article Synopsis
- * The study discusses two potential scenarios for 2030: a "business-as-usual" path continuing current trends, and a more hopeful future achieved through informed action towards the UN SDGs.
- * Key drivers for these futures include the eagerness for climate action, response to extreme events, and implementation of climate interventions, with various proactive measures suggested to promote a sustainable future such as enhancing economic incentives and supporting local initiatives.
Article Synopsis
- The study explored the impact of moderate-to-vigorous physical activity (MVPA) on bone mineral content (BMC) in prepubertal children, specifically looking at whether this relationship is influenced by free leptin index.
- The analysis involved 401 children, measuring MVPA through accelerometers and BMC using dual-energy X-ray absorptiometry, finding a positive direct effect of MVPA on BMC in both genders.
- Results indicated no significant mediation or interaction involving free leptin index, suggesting that the beneficial effects of MVPA on BMC occur through other factors, possibly related to mechanical loading, rather than leptin levels.
