Muscat: The Arctic tundra, long considered one of the planet’s most fragile ecosystems, is experiencing rapid and unexpected changes due to climate warming.

According to Oman News Agency, Over 40 years, 54 scientists tracked more than 2,000 plant communities across 45 sites from Canada to Scandinavia. contrary to expectations, there were no clear winners or losers-some areas saw an increase in shrubs and grasses, while flowering plants declined.

The shifts are driven by rising temperatures and longer growing seasons, with shrubs outcompeting slow-growing mosses and lichens, which caribou and other species rely on. Lead author Mariana García Criado of the University of Edinburgh called the findings an ‘early warning sign’ of deeper ecological disruptions.

While plant diversity is increasing in some regions, experts warn the changes could destabilize food chains and threaten Indigenous communities dependent on traditional ecosystems. Scientists stress the need to prepare for cascading effects, as the Arctic’
s transformation signals global repercussions.
