N. Hemisphere Snow Cover Trend Has In Fact Been Upward Over Past Quarter Century

-

USA’s National Oceanic and Atmospheric Administration (NOAA) providesdata here on snow cover.

Because global warming is supposed to be leading to less snow, one would think that snow cover in terms of area would be trending downwards over the past 50 or so years. However, the data tell us a very different story.

Surprisingly wintertime snow cover area has actually been trending upwards over the past 50 years and all-year snow cover in the northern hemisphere has been pretty much steady, and even of the rise over the past 25 years!.

The following NOAA chart shows us the northern hemisphere show cover for November:

snow-nov

Clearly the November trend is solidly upwards, with especially great area extents over 5 of the last 6 Novembers. The next chart is for December:

snow-dec

In December as well we see especially vast snow cover over many of the past 15 years – even higher than the winters of the 1970s, when we were being bombarded with warnings of global cooling.

Next we present the data for January, where see no change over the past 48 years:

snow-jan

However in January, over the past 25 years we can make out a rising trend as well. Claims that snow is becoming a thing of the past are very false.

February’s trend tell us the same story: greater snow cover:

snow-feb

Again here as well the powerfully upward trend is clearly visible since 1990.

The same is true for the autumn months of September and October.
