RAPIDLY disappearing Arctic sea ice is about to set a record after an "absurdly warm" winter at the top of the world.
For the second year running, it will cover less of the Arctic Ocean than ever before.
The revelation comes as scientists are increasingly worried that the heating of the region could escalate out of control.
Most attention on the melting sea ice so far has been focused on the increasingly low minimum levels it reaches each September.
Its nine smallest coverages have all occurred in the past nine years, with the record being reached in 2012, 3.41 million sq km - 44% less than the average of the previous three decades, and a full 16% lower than the previous record, in 2007.
