♦ IPCC TAR (2001): “Milder winter temperatures will decrease heavy snowstorms”
♦ Kunkel et al., 2002: “Surface conditions favorable for heavy lake-effect snow decreased in frequency by 50% and 90% for the HadCM2 and CGCM1 [models], respectively, by the late 21st Century. This reduction [according to models] was due almost entirely to … an increase in average winter air temperatures.”
♦ IPCC AR4 (2007): “Snow season length and snow depth are very likely to decrease in most of North America”
♦ Kapnick and Delworth, 2013: “In response to idealized radiative forcing changes, both models produce similar global-scale responses in which global-mean temperature and total precipitation increase while snowfall decreases. … By using a simple multivariate model, temperature is shown to drive these trends by decreasing snowfall almost everywhere” (press release) “In North America, the greatest reductions in snowfall will occur along the northeast coast, in the mountainous west, and in the Pacific Northwest. Coastal regions from Virginia to Maine … will get less than half the amount of snow currently received.”
The reality: Blizzard activity jumps fourfold
For example a paper by Coleman and Schwartz, 2017 revealed 713 blizzards over the 55 years with 57 federal disaster declarations resulting. Of these 57 declared disasters, more than a half have occurred since the year 2000.
Finally, a study conducted by Hatchett et al., 2017 found a “winter snow level rise in the northern Sierra Nevada from 2008 to 2017”. Sea surface temperatures offshore California were observed to be related to snow cover.
