Arctic sea ice reached its lowest extent of the year on 12 September, marking the end of the summer melt season. The figure, reported with reference to the EU's Copernicus monitoring service, is being watched by climate observers as a key indicator of long-term warming in the polar north.
Why now: The annual sea ice minimum is a closely tracked climate indicator, and its yearly extent fuels debate about Arctic warming trends.
