Summer Arctic Ice loss accelerating way faster than predicted

When I wrote Arctic Rising, 2050 for ice-free sounded science fictional. Now some scientists are saying it’s 2040:

“Looking at not just the area, but also the age and thickness of sea ice is a key aspect of understanding why an ice-free Arctic summer could occur in far less time than previously thought – perhaps less than a decade from now. It is also a level of complexity often ignored by the media.”
