Here’s the alarming amount of ice California’s longest glacier just lost in the heat wave
Mount Shasta, the widely recognizable face of California’s far north, has lost almost all its defining snow cover for a second straight year. Another summer of scorching temperatures, punctuated by the recent heat wave, has melted most of the mountain’s lofty white crown, typically a year-round symbol of the north state’s enduring wilds. … While the seven named ice sheets have been retreating for years, if not decades, the diminishing snow, which helps insulate the glaciers and keep them from thawing, has caused an unprecedented melt-off: About 20% of the glaciers’ ice, and possibly more, is expected to have vanished over the past two summers.
