Glacier Growth Caused by Climate Change?

As we already know, most of the world's ice is melting fast. Not so on California's Mt. Shasta, where glaciers are actually growing because of global warming.

Here's how it works: The Pacific Ocean is warmer now than in years past. Warmer temperatures mean more moisture, which in turn means more snowfall on Mt. Shasta.

This is not the case for other nearby mountain ranges. The Sierra Nevada range, which is just 500 miles south of Mt. Shasta, is losing ice—in fact, it has lost about half its ice over the past 100 years.

Like Antarctica's increasing sea ice, the Mt. Shasta glaciers are another piece of evidence that global warming is a little more complicated than most of us think.
