Rapid climate change is upending established plant diversity and growth patterns in the Arctic, with species blooming in some areas and declining in others, suggests a study published today in the journal Nature.

The decades-long study of more than 2,000 plant communities across 45 areas in the Arctic tundra found that many locations saw vegetation change in type, abundance and growth, between 1981 and 2022.
