Exposure to cold and heat could affect adolescents' mental health

Exposure to cold and heat could affect adolescents' mental health, according to a study published in JAMA Network Open. The research, led by the Barcelona Institute for Global Health (ISGlobal), was conducted with nearly 5,000 adolescents from the Netherlands (3,934) and Spain (885). The results showed how exposure to environmental temperatures influences psychiatric symptoms such as anxiety, depression, and attention problems.

Temperature-related deaths could rise by 50% in Europe by the end of the century

An international team has analysed temperature and mortality data from 854 urban areas in Europe, and estimated that temperature-related deaths could increase by 50 % by the end of the century - which would mean up to 2.3 million more deaths - if no climate change mitigation measures are taken. This percentage is even higher in southern parts of the continent, such as Spain. The results are published in the journal Nature Medicine.

Change in building materials could store billions of tonnes of carbon

US researchers have estimated that replacing conventional building materials in new infrastructure with CO2 capturing alternatives - such as mixing carbon aggregates into concrete or using bio-based materials in bricks - could store billions of tonnes of carbon dioxide per year. According to the study, published in the journal Science, the move could help meet greenhouse gas emission reduction targets.

Two IPBES reports propose global changes to tackle current environmental crises

Meeting in the city of Windoek (Namibia), the plenary of the IPBES - Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services - has ratified two new reports: the Nexus Assessment and the Transformative Change Assessment. Three of their authors explained the main findings and the changes they propose at a briefing organised by SMC Spain.

Population in drylands could double by 2100 under worst-case climate change scenario

More than three-quarters of the earth's land surface experienced drier climates between 1990 and 2020 compared to the previous three decades, according to a new report by the United Nations Convention to Combat Desertification. Over the past 30 years, 40.6 percent of the global landmass, excluding Antarctica, is classified as drylands, three percentage points more than the previous three decades. The report, which is being presented at the COP16 on desertification being held in Riyadh, Saudi Arabia, also shows that 2.3 billion people were living in drylands in 2020, a population that could rise to 5 billion by 2100 under a worst-case climate change scenario.

First Arctic ice-free day could happen before 2030

In three to six years, the first ice-free day in the Arctic could occur if a series of extreme weather events - such as an unusually warm autumn, winter and spring in the region - occur, according to a study comparing various models and scenarios in Nature Communications. An ice-free day refers to a day with Arctic Ocean ice coverage of less than 1 million square kilometres; the average coverage was 6.85 million square kilometres between 1979 and 1992.

From COP29 to the Heidelberg Accord: the role of research funders in the fight against climate change

Funding has been one of the major obstacles to agreement at the Baku Climate Summit. More sustainable science also depends on how research is funded. It is imperative that research institutions also develop strategies to incorporate more sustainable practices and contribute to climate neutrality.
