Most research on “forever chemicals” focuses on how best to remove them from the environment. But solutions to tricky problems often emerge from the most unexpected of places—as demonstrated by a new study that instead redirects the pollutants into becoming tools for extracting precious lithium. In a recent Nature Water study, a team led by Rice University researchers describes a novel way to use spent perfluoroalkyl and polyfluoroalkyl substances, or PFAS, to recover lithium from high-salinity brine pools. The team tapped into the fluorine content inside PFAS leftovers, using it to attract lithium from briny water. Remarkably, the team was able to collect lithium fluoride at 99% purity and confirmed that the sample was pure enough to boost the stability and performance of lithium-ion batteries.

This paper analyses General Social Survey (United States) data and provides evidence that the advent of Facebook and other social media platforms has widened the gap in scepticism towards science between low-educated Americans and their more highly educated counterparts. The same trend holds true when considering distrust in medicine, the press and television. Overall, the results suggest that education may serve as a protective factor against the influence of fake news, disinformation and misinformation. Additionally, a heterogeneity analysis shows that the increase in distrust is particularly pronounced among young people. Further analyses reveal that political affiliation plays a role in shaping attitudes towards science and that the likelihood of voting for the Republican Party has increased among low-educated individuals. A comprehensive set of robustness and placebo tests supports the reliability of these findings.

Predictably, soon, most young people will reject extremist views. This will be none too soon because it is the essential step leading to global political leadership that appreciates the threat posed by climate’s delayed response to human-made changes of Earth’s atmosphere. Then the annual fraud of goals for future “net zero” emissions announced at United Nations COP (Conference of Parties) meetings might be replaced by realistic climate policies. It is important, by that time, that we have better knowledge of the degree and rate at which human-made forcing of the climate system must be decreased to avoid irreversible, unacceptable consequences.

This year elections are taking place across the globe, covering almost half of the world’s population. It is also likely to be, yet again, the hottest year recorded as the climate crisis intensifies. The Guardian asked young climate activists around the world what they want from the elections and whether politics is working in the fight to halt global heating.

Quelles conséquences peut-on déplorer en France à cause du changement climatique ? Quelle trajectoire d'émissions sommes-nous en train d'emprunter ? Quand est-il de nos politiques publiques pour répondre au problème ? Et enfin, un aparté sur la trajectoire des émissions mondiale. Je réponds succinctement à ces 4 parties dans la vidéo en utilisant le dernier rapport du HCC. Le Haut conseil pour le climat est un organisme neutre et indépendant qui évalue l'action publique en matière de climat. Vous retrouverez plusieurs chiffrés clés extrêmement importants à retenir.

Climate change has important implications for the health and futures of children and young people, yet they have little power to limit its harm, making them vulnerable to climate anxiety. This is the first large-scale investigation of climate anxiety in children and young people globally and its relationship with perceived government response.

More than half of young people think "humanity is doomed" due to climate change. We need to reframe the narrative from doom and sacrifice, to one of opportunity.
