Arctic sea ice minima – September 17ᵗʰ

The 2019 summer melt of Arctic sea ice bottomed out on September 17th, with an estimated sea ice extent of 4.1 million square kilometres. This was 34.8% below the 1981-2010 long-term average, and made the 2019 minimum the second lowest since 1979, with only the minimum of 3.34 million square kilometres that occurred in 2012 lower, and obviously not a healthy state of affairs to say the least.
