A study by a team from the ClimaMeter project claims that the intensification of rainfall from the DANA that devastated Valencia and other regions on 29 October is mainly attributed to human-induced climate change. Natural climate variability, on the other hand, probably played a modest role. According to the analysis, this DANA was driven by very exceptional weather conditions. The work also shows that the DANA-like depressions that cause flooding in the southeastern peninsular are up to 15 % wetter than they were in the past. In addition, temperatures are up to 3°C warmer, which favours storm formation in these events over the Mediterranean basin.
An international team with Spanish participation has analysed which day of the week has the highest risk of suicide mortality, and it is Monday. The research, published in The BMJ, includes more than 1,700,000 suicide cases registered in 26 countries - including Spain - from 1971 to 2019. The data also show a sharp increase in the risk of suicide on New Year's Day in most of the countries analysed. Taking these results into account, the authors propose that they should be used to define plans and awareness-raising campaigns.
An international report by the Global Commission on the Economics of Water says the water crisis puts more than half of the world's food production at risk by 2050. It also claims that it threatens an average loss of 8% of GDP in countries around the world by 2050, with losses of up to 15% in the lowest income countries.
Lithium, a material widely used for battery production, is typically extracted from rocks and concentrated brines, but these reserves are expected to run out by 2080. The alternative is to evaporate more diluted brines (such as seawater), but the traditional process is inefficient, polluting, and consumes large amounts of water. Two new studies published in Science propose two more viable and environmentally friendly alternative methods: the first uses a membrane that filters lithium through a transpiration system similar to that of plants, requiring only solar energy. The second combines electrodes to mimic a battery and move lithium from the brine (cathode) to fresh water (anode).
E-cigarettes, vapes, pods, mods... The popularity of these devices continues to grow, especially among young people. According to a Spanish survey, more than half of the adolescents aged 14 to 18 have used them at some point. Vaping control varies from country to country: in Spain, vaping products have been regulated since 2017 and the new anti-smoking plan aims to equate their legislation to that of tobacco, while the United States imposes fewer restrictions. In this brief guide, we explain what is known and not known on controversial issues such as the safety of electronic cigarettes, their risks or whether they are useful to quit tobacco.
In 2022, 62 million tonnes of e-waste were generated worldwide, a figure 82% higher than the 34 million tonnes recorded in 2010, according to a United Nations report. The 2022 figure represents an average of 7.8 kilograms per capita per year worldwide, compared to 19.6 kg in Spain. Only 22.3% of this amount of global e-waste was documented as properly collected and recycled, says the Global E-waste Monitor 2024.
In 2010, nearly 1,000 sub-basins around the world were facing water shortages. But when considering not only water quantity, but also water quality, this figure rises to more than 2,500, according to a study published in Nature Communications. By 2050, the authors estimate that up to a third of sub-basins will face severe shortages of clean water, which could affect 3 billion people. Southern China, Europe, North America and Africa will be the most affected regions.
Las lluvias torrenciales caídas en Libia hace dos semanas fueron 50 veces más probables por el calentamiento global provocado por la acción humana. Algo similar ocurría con las lluvias caídas en Grecia, Bulgaria y Turquía, que fueron 10 veces más probables por el cambio climático, según concluye un estudio de atribución rápido de la Word Weather Attribution (WWA). La investigación apunta a que la tragedia en Libia se agravó por otros factores humanos, como construcciones en llanuras inundables y presas en mal estado. Los autores también analizaron las inundaciones registradas en España a principios de septiembre y concluyeron que precipitaciones tan intensas se esperan una vez cada 40 años.
On Tuesday, Russian President Vladimir Putin announced that he is suspending Russia's participation in the New START treaty, a bilateral agreement signed with the United States that has been in force since 2011 and that limits and controls the nuclear armament of both powers.
Procrastination in a sample of more than 3,500 students was associated with the development of both mental and physical health problems nine months later, according to a study conducted at several universities in Sweden. The results are published in the journal JAMA Network Open.
