According to the results of a research study conducted by NASA the ice in the Arctic is melting faster than before during the warm season, yet growing faster than before during the Winter. The December 2018 summary of the NASA research states that the rate of melting exceeds the rate of growth and thus the overall ice extent is going down.
These are very interesting findings. I personally wonder if it is reasonable to expect the processes to even out at one point as more open water during the Summer should translate into more evaporation, higher humidity and higher rate of precipitation all year round, including more snowfall during the cold months. Snow being reflective, we may get lower temperatures and thus more effective ice formation which will eventually catch up to, or even overtake, the ice melting process of the warm season.
Not sure what to make of it all - but I think the above may be a hypothesis worth some consideration.
