Polar snow and ice cover rarely cooperates, no matter what side of the warming issue you may be on; it changes so fast.
When ice cover climbs, skeptics like to claim that it shows global warming isn’t what it is often hyped up to be. And when ice cover drops to satellite era record lows, the alarmists start screaming and hollering, forgetting that low ice levels were not uncommon in the past 100 years.
They freaked out just some months ago when the yearly autumn Arctic sea ice recovery faltered and fell to “record” lows. Immediately they began predicting near ice-free conditions for the coming summer.
Just as the weather does, polar ice and snow cover also acts unpredictably, and now just a few months later Northern Hemisphere snow and ice cover is back within the normal range.
Winter snow and ice cover trend for the Northern Hemisphere has in fact been trending upwards since statistics started.

And when one applies the 30-year weather mean used to define climate, the winter trend since 1987 is strongly upwards. So is the autumn trend. This 2017 winter was well above average, ranking in the top 10.
The Greenland snow and ice surface mass balance is currently also near record levels:
As meteorologist Joe Bastardi said, it’s going to take a fair amount of warmth to make the added ice go away again.
