Arctic spring's 'rapid advance'

Spring in the Arctic is arriving "weeks earlier" than a decade ago, a team of Danish researchers have reported.
Ice in north-east Greenland is melting an average of 14.6 days earlier than in the mid-1990s, bringing forward the date plants flower and birds lay eggs.
The team warned that the observed changes could disrupt the region's ecosystems and food chain, affecting the long-term survival of some species.
