It was so hard to get close to Ptarmigans last winter in #Varanger explorewilder.com/en/photo/240 I had more luck in summer time on my hike through #Abisko National Park explorewilder.com/en/photo/230 but I managed to take sharper photos this time in #Svalbard thanks to a rented super zoom lens. explorewilder.com/en/photo/250 explorewilder.com/en/photo/250

Svalbard, Chios, El Hierro: How these European islands have successfully avoided overtourism.

Mass tourism is once again testing the limits of Europe's most visited places - and with limited land and fragile infrastructure, islands are some of the destinations worst affected by mass tourism.

'Cryosphere meltdown' will impact Arctic marine carbon cycles and ecosystems, new study warns

A new study led by Jochen Knies from the iC3 Polar Research Hub has found worrying signs that climate change may be undermining the capacity of #Arctic #fjords to serve as effective #carbon sinks. The findings suggest that the capacity of polar #oceans to remove carbon from the #atmosphere may be reduced as the world continues to heat up.

Knies and his collaborators discovered that rapid changes in the Arctic are transforming vibrant fjord ecosystems like Kongsfjorden in #Svalbard. Published in Communications Earth & Environment, their findings document not only a shift in phytoplankton communities due to melting ice but also a worrying decline in the capacity of these fjords to sequester carbon.

Warmer waters can enhance #phytoplankton growth during sunlit summers, presenting an initial opportunity for increased productivity. However, as the waters become stratified, essential nutrients become harder to access, leading to a double-edged sword: while we may see a rise in phytoplankton #biomass, the efficiency of CarbonCapture could decline.

Continued thread

Det er jo egentlig slående at USA legger Krim på bordet uten å ha avklart med #Ukraina først, særlig i og med at å forhandle om land er i strid med Ukrainas #grunnlov. Det ligger heller ingen #sikkerhetsgarantier i forslaget.
Forslaget må være motiverende for Putin, siden forbruket av soldater og materiell gir avkastning.

Dette handler jo også om #Grønland og #Taiwan, men potensielt også #Svalbard
