With ice extent above the 21st century average and little trend for seventeen years, experts have pushed their predictions of an ice-free Arctic out a few years.

“the earliest ice-free conditions (the first single occurrence of an ice-free Arctic) could occur in 2020–2030s under all emission trajectories and are likely to occur by 2050. However, daily September ice-free conditions are expected approximately 4 years earlier on average, with the possibility of preceding monthly metrics by 10 years. Consistently ice-free September conditions (frequent occurrences of an ice-free Arctic) are anticipated by mid-century (by 2035–2067)”

Perhaps a more reasonable forecast would be 3550.
