The situation keeps deteriorating
In "The cracks area" , more cracks are appearing and a new massive iceberg is shaping up

@tietoukka.bsky.social"Canada's only remaining epishelf lake [...] is gone, along with the unique ecosystem it supported, scientists confirmed in a new study."
"the irreversible loss "marks a regime shift and the end of a 4000-year era.""

@earthwave.bsky.socialEarth Observation measurements can reveal melt rates beneath Antarctic Ice Shelves - a key driver of ice loss. We’ve been sharing this research this week at the ESA Polar Science Cluster Collocation Meeting in Innsbruck!
