According to a Science Daily article, two glaciers in Northern California's Trinity Alps seem to be holding their own. Snippets:
"First of all, it's surprising that these glaciers still exist because they are located below 9,000 feet," said Heermance [author of the study Richard Heermance]. "Most California glaciers are located above 10,000 feet. And the glaciers in the Sierra Nevada have clearly receded over the past 50 years."
Yet the Trinity glaciers and those on Mt. Shasta show minimal shrinkage. The hypothesis of Heermance and his colleague Richard Briggs, a post-doctoral fellow at Caltech, is that these glaciers are being sustained due to higher precipitation. The increase in temperature attributed to global warming, say the geologists, is offset by the increased precipitation. Globally temperature has increased 1 to 2 degrees Farenheit since 1970.
