Look at the "whole picture", Paul.

True, there is more extensive snow cover in 2014, but that proves nothing other than that there was heavy snow that year. Even here in UK we have isolated years in which we have a lot more snow than usual. Often, these do not co-inside with years of lowest temperatures.

Balance against the extra snow the fact that the areas of lowest temperature are smaller in 2014. Either side could find supportive evidence.

There never was nothing.
