With just days to go before COP28 kicks off in Dubai -a major city in the oil-rich United Arab Emirates- climate experts are torn between mistrust and hope that world leaders will reach ambitious agreements to combat the climate crisis.
Living as a private renter is associated with faster biological ageing than owning a home, according to a study using a UK database with data available on 1,420 people. The team, whose research is published in the Journal of Epidemiology and Community Health, used DNA methylation data - chemical modifications - to measure people's biological age, and says this correlation is stronger than the association between biological ageing and unemployment, or having been a smoker. Apart from blood samples from the database, the research also used historical data from a national survey.
Capping the consumption of European households who consume most energy - those with the highest incomes and education levels - could achieve "considerable emissions reductions", according to a UK research team. This benefit could also be achieved by simultaneously increasing the consumption of the poorest and most vulnerable users. The analysis, published in Nature Energy, estimates that limiting the energy use of the top 20 % of consumers in 27 countries in Europe would reduce emissions from domestic energy consumption by 11.4 %, 16.8 % from transport, and 9.7 % from total energy consumption. The article states that the association between high income and high energy consumption is particularly strong in countries such as Spain, where income inequality is relatively high.
