As Cop17 kicks off, records since 1921 show more bee species declining than increasing in all parts of Europe except the Alps

Most of Europe’s wild bee species and about half of its hover fly species have declined over the last century, a study has found, as a UN biodiversity summit begins in Armenia.

Records since 1921 show more bee species are declining than increasing in all parts of Europe except the Alpine region. The richness of bee and hover fly species suffered a persistent drop in the Atlantic and Continental regions, the study found, though trends in other regions were mixed or even positive.

Peak of French mountain now 4,807 metres high and fluctuates year by year due to changes in Alpine climate

Western Europe’s highest mountain shrank by more than a metre last year. The peak of Mont Blanc in France now stands 4,807.47 metres above sea level, a team of surveyors said on Wednesday, putting “the roof of Europe” 1.29 metres lower than in 2025.

The mountain is about 4,792 metres tall but the summit constantly shifts as heat, wind and precipitation change the thickness of snow and ice on top. The height scientists recorded during an expedition last month was 1.88 metres greater than it was in 2023, when it reached the lowest levels in recent memory.
