I'm really interested in what evidence the people "weenieing" this statement of fact have in rebuttal. Because over my lifetime, this has clearly been the case. Here is the last 35 years of data from a diverse assortment of locations. Snowfall has plummeted, especially in lake effect and upslope areas, where a simple linear trend implies snowfall has been cut in half since 1990 (see, e.g., Cleveland and Elkins, W. Va.). I'm sure they'll complain about the start date - but the 1990s were considered mild at the time, with people pining for the snowier/colder 60s and 70s and comparing it to the so-called "cyclical warming" of the 1930s and 40s. This period also covers the bulk of my lifetime and with consistent procedures for snow measurements.
