Look at this dip during the last week !

Could it be an anomaly with satellite imaging, a random statistical blip, or is something huge just about to start ?
this is showing the history of area (quantity) of sea covered by ice around Antarctica (South), with each curve being a different year.
In this context, less sea ice is bad news. It is winter there, so the overall ice is still strong. Summer is what matters most (you can see the months on the chart.) Although, leaving winter with less sea ice can make the summer ice situation worse.
