As temperatures in the Northwest continue to rise this century, scientists expect snowpack to keep declining.2 In the Cascades, scientists project a reduction of as much as 40
percent in the amount of
snow on April 1 by the 2040s,
under a business - as - usual emissions path.11, 12
Percent snow depth changes in March (only calculated where climatological
snow amounts exceed 5 mm of water equivalent), as projected by the Canadian Regional Climate Model (CRCM; Plummer et al., 2006), driven by the Canadian General Circulation Model (CGCM), for 2041 to 2070
under SRES A2 compared to 1961 to 1990.
