Satellites record second lowest Arctic sea ice extent since 1979


"The polar oceans are among the most rapidly changing oceans in the world. The yearly cycle of the build-up and melting of Arctic sea ice is one of the earth’s vital signs and a key climate variable monitored by scientists.

While they may be far from the world’s major population centres, changes in the polar regions have global implications: they affect the world’s climate through carbon storage and/or release, heat balance, and other environmental and ecological impacts.

One of the most visible indicators of this change is the reduction in the extent of Arctic sea ice by the end of September each year." ～ press release @UNEnvironment
