If it has less than that, it is considered ice free. Defining "ice-free Arctic" is less precise. It is not likely that every last bit of ice will disappear from the Arctic Ocean any time soon. Even at the end of the summer melt season, there will likely be some remnant ice in some locations. According to the NSIDC website, many climate scientists use the term "ice-free' Arctic as a shorthand way of saying that there will be very little reflective surface at the end of the summer melt season. @rach4775

There seem to be various opinions on what constitutes ice free, with some scientists holding that ice free is <10% sea ice coverage of the Arctic for 30 consecutive days and others holding to no sea ice for two months. I'm in a Polar Oceanography course and doing a research project on the various predictions for Arctic sea ice levels. How would you define “an ice free Arctic”?
