🍁 Trees in Europe are increasingly dying prematurely. A new WSL study on French #forests now shows that it is not only extremely dry summers but #climate anomalies in general that are driving tree mortality – particularly warm and wet springs: www.wsl.ch/en/news/why-... @lsce-ipsl.bsky.social 🌍

Why Europe’s trees are dying

Deviations from the usual climate are causing trees to die prematurely. Even favourable growing conditions can have a negative impact.

"Die Vorstellung eines Klebers, der den Berg zusammenhält, ist für grosse Hanginstabilitäten [...] unpassend", sagt #SLF Forscher Robert Kenner über die gängige Meinung, #Permafrost sei wie ein Kleber. Details: www.slf.ch/de/news/perm... 📷️ 1: Marcello Negrini / 2: Stefan Suhner #CERC

Weathered rock layers beneath the soil influence how groundwater moves during storms. The findings of a new study, led by ETH Zurich researcher Seulgi Moon (formerly UCLA), help explain when and where shallow landslides occur and could improve hazard prediction.

🌄 New #MeteoSwiss research: Swiss lowlands heat up faster in autumn & winter as fog declines, while mid-elevations warm more in spring due to snow loss. ➡️ Some popular #climate datasets miss these elevation-specific signals entirely. Time-consistent, high-resolution observations matter. 🌍❄️

The catastrophic collapse of the Birch Glacier that wiped out the Swiss mountain village of Blatten in May has triggered an unprecedented scientific effort to understand how a mountainside could break up so violently – and what might come next.
