Global warming is causing most glaciers worldwide to melt; however Mount Shasta’s glaciers are an exception. Shasta’s glaciers have about doubled in size since the 1950s. Scientists think this is due to the warmer Pacific ocean releasing more water vapor, which then moves inland to drop more snow on Mount Shasta. This increase in snow is large enough to offset increased rates of snowmelt from warmer air temperatures.
Most climatologists agree that global warming is happening. One question for outdoors people: “How do we adjust our outdoors activities around the changing climate?” What about you? How is the changing climate affecting your recreation outdoors? How do you plan to cope with it?
We had a very dry spring in far Northern California, and this meant the main hiking route to the summit of Mount Shasta up Avalanche Gulch via Lake Helen lost most of its snow by late June, making climbing far more difficult.
