2026 n’arrive pas plus tôt qu’envisagé! L’analyse👇 à partir d'un grd ensemble de simulations montre qu’un été type 2026, certes extrême, est bien présent dans la gamme des étés possibles attendus pour cette décennie 2020-2029. L’impréparation est un choix politique, pas une défaillance scientifique.

🍃 The stability of trait–herbivory relationships across environmental gradients suggests that growth–defence trade-offs are conserved across biological scales, suggesting that accounting for within-species trait variation could improve predictions of future ecosystem processes. 👉️ buff.ly/rjSdUuE

From love songs to lullabies, songs spanning the globe—despite their diversity—exhibit universal patterns, according to the first comprehensive scientific analysis of the similarities and differences of music across societies around the world. Learn more on #WorldMusicDay: scim.ag/43Ct5Ib
Density plots for each society show the distributions of musical performances on each of the three principal components (Formality, Arousal, Religiosity). Distributions are based on posterior samples aggregated from corresponding ethnographic observations. Societies are ordered by the number of available documents in the NHS Ethnography (the number of documents per society is displayed in parentheses). Distributions are color-coded according to their mean distance from the global mean (in z-scores; redder distributions are farther from 0). Although some societies’ means differ significantly from the global mean, the mean of each society’s distribution is within 1.96 standard deviations of the global mean of 0. One society (Tzeltal) is not plotted because it has insufficient observations for a density plot. Asterisks denote society-level mean differences from the global mean. *P < 0.05, **P < 0.01, ***P < 0.001.
