‘Glaciers melting at a faster rate’

WASHINGTON: Nearly all of the world’s glaciers are losing mass – and at an accelerated pace, according to a new study that experts said painted an “alarming picture”, foreign media reported.
The research published on Wednesday in the science journal Nature provides one of the most wide-ranging overviews yet of ice mass loss from about 220,000 glaciers around the world, a major source of sea-level rise.
Using high-resolution imagery from NASA’s Terra satellite from 2000-2019, a group of international scientists found that glaciers, with the exception of the Greenland and Antarctic ice sheets which were excluded from the study, lost an average of 267 gigatonnes of ice per year.

Nearly all of the world s glaciers are losing mass - and at an accelerated pace, according to a new study published Wednesday that could impact future projections for ice loss.

Orfanou said that by analyzing both tools and finished objects the team were able to better understand how metalwork processes developed in Ribe over time. The plethora of crucibles (clay cups) that were discovered stand testimony to the vast amount of metal that was smelted over fires at this settlement. The authors found that early Viking craftspeople in the 9th century adopted a different and “more heat-resistant clay for their crucibles, which would last longer,” according to the research paper.
Mapping Metals Across the Viking Age
A series of “rapid technological advances” were noted at the beginning of the Viking Age and the researchers wrote that this was because craftspeople were exposed to new skills. The findings published in
