Some glaciers are growing...

Here's one that is growing rapidly...but there are many others...

MOUNT SHASTA The debate over global warming has taken a pretty odd twist in Northern California. Up on Mount Shasta, the glaciers are not behaving like you'd expect.

Big mountains often produce their own weather patterns. Mount Shasta, at 14,162 feet seems to have a mind of its own these days. Shasta has seven glaciers. The biggest is the one on the middle, Whitney Glacier. What has surprised scientists about the glacier is that if the theories about global warming are true, the glacier ought to be shrinking, but it's not.

“Unlike most areas around the world, these glaciers are advancing, they are growing. Thirty percent in the last fifty years,” says scientist Erik White.

White and mountain climber Chris Carr are Shasta experts.

"Every year it's a little bit different. But the glacier changes dramatically, year to year," says Carr.

So why are the glaciers larger today than they were a century or more ago?

"Mount Shasta is right at the very northern end of areas influenced by El Nino and were at the southern end of areas affected by La Nina. So between the two we get to see the benefits of that which means more snow and rain in this area," says White.
