JAXA Antarctic Extent as at 11 Feb 2018 2,340,990 km2.
The last four days have seen extent loss slowing to a crawl, and is now 104k above the 2017 extent on that date.
There are on average (last 10 years) just 8 days (ranging from 5 to 18), 0.21 million km2, 1.3% of extent loss to go. Average loss would result in a minimum of 2.13 million Km2 , just .02 million km2 below 2017's record low. The range of results from the last 10 years remaining extent losses is from 1,824,585 to 2,280,585 km2.
These are observations, not predictions. What will the weather and the ocean currents do? Will 2018 match the very low 2017 extent gains after the minimum ?
Looking beyond the minimum, note from the graph how extent gain in 2017 was very much below average. To stay at record lows, 2018 will have to do the same.
