What is happening in the Arctic?
2309 ppb I can assure you that the satellite did not miss any of its orbits.
They could easily change their color scale so that we could have readings of 2000, 2100, 2200 and so on, but they refuse to, because that would be disclosing too much information to the public. They do not want you to know how bad is now is.
Arctic sea ice #'s
Annual volume: 12,898 km³ (*record* low)
Year–to–date average volume: 14,938 km³ (3rd lowest)
Annual extent: 9,951,944 km² (2nd lowest)
Year–to–date average extent: 12,121,879 km² (*record* low)
Annual volume (or 365–day average) is +3.7 km³/day, +25/week, +116/month, –633/year, –588/5year (–4.4%)
Annual extent is –0.25k km²/day, –3k/week, +7k/month, +238k/year, ±0k/5year (±0%)
Arctic sea ice extent has been lowest on record for the date for 13 consecutive days.

Statistical 1–3–year linear decline trends suggest a 6–month ice–free Arctic Ocean by 2020–21.
ESAS and other peripheral seas receive stronger sunshine for longer, and are also more exposed to waves and other strong oceanic feedbacks, like loss of Arctic inversion and stratification, so likely to go ice–free for the ½ year by 2019–20.
Methane is already escaping from the ESAS seabed in massive amounts, yet the volume of these releases is likely to pick up dramatically once sunshine and ocean heat are no longer spent melting local sea ice.
