Data from the University of Rutgers show that northern hemisphere snow cover in the fall and winter have trended upwards since data recording began in 1967.

The following chart shows northern hemisphere snow cover for fall, where we see a formidable upward trend:

Next we see the chart for wintertime northern hemisphere snow cover. Though the trend is not as pronounced as it is in the fall, the trend has been modestly upward.

Finally we look at the latest Arctic ice volume data from PIOMASS:

As we can observe, Arctic ice mass has in fact stabilized over the recent decade after having shrunk during the previous 2001-2010 decade.

It should be noted that data going back to 1900 show that Arctic sea ice AREA had been low as well during the 1930 to 1960 period before reaching a peak in the 1970s and 1980s.

In summary, nothing to worry about up in the Arctic.

    My thanks for a timely,sensible summary.

    Thanks to the authors for their hard work and persistance.

    I noticed from the Rutgers graphs that the Autumn and Winter snow was increasing, but the spring snow was declining rapidly, so something is shifting. I don’t know what, though.

      It’s a dynamical system, it would be amazing is nothing would shift.

    The great variations from year to year are most interesting. has anybody any suggestions?

    The large year to year variations in snow extent are very interesting. has anybody any suggestions why this is the case?
