PORTLAND, Ore. The seven largest of Mount Hood's 11 glaciers have shrunk by an average of more than 30 percent since the beginning of the last century, according to calculations by a Portland State University graduate student.
Keith Jackson, who is part of a glacier research team financed by the National Science Foundation and NASA, estimates that Sandy Glacier, on Mount Hood's west slopes facing Portland, covers about 60 percent less ground than it did a century ago and Eliot Glacier has lost at least half of its ice in the last 100 years.
And scientists think glaciers might recede faster in the coming century because of warmer temperatures. Average low temperatures at Eliot Glacier have been above freezing during at least six of the last 12 years, more than any such period in the last 110 years, according to Oregon Climate Service calculations.
Scientists in the University of Washington's Climate Impacts Group predict the Northwest will warm nearly as much in the next 20 years as it has in the last 100, about a degree Fahrenheit.
It's almost universal that all glaciers are retreating, said Peter Clark, an Oregon State University professor who's an authority on glaciers. The signs of retreat are dramatic and accelerating.
It signals that the cause of that change is overwhelming other factors, he said. The fingerprint of global warming is increasing on a global scale.
Studies that show the glaciers receding do not surprise climbers of Mount Hood, who say they now skip certain routes to the summit because rocks and ice once locked solidly in place now break loose.
Warming and the receding glaciers are very much affecting the recreation potential and the dangerousness of it on all sides of the mountain, said Vera Dafoe, who has long led hikes on the mountain for the Mazamas. It has changed enormously.
Well, I didn't get in the first "Bush's Fault" but I am the first to say:
We're DOOOOOOOOOOOOOOOOOOMED!
DOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMMMMMMMEEEEDDDDDDDDDDDDDDDDDD!
Oh, yeah--Hood is a volcano, one of those things that spew out "greenhouse gases".
Keith Jackson?. . .FUM BLLLLLLLLLEEEEEEEEE!!
That's required bathroom reading in my house ;)
I loved oregon though.
The Columbia river valley is amazing.

Find it interesting that all these measurements involving melting that started about 100 year ago. I assume that's a trend from before the massive production of greenhouse gases.
It's a lot warmer in OR than WA.
Americas youngest glacier is also its fastest growing glacier. Scientists estimate that the thickness of the glacier has increased by nearly 50 feet per year. Not only is it growing thicker, it has been advancing as much as 135 feet per year.
Shows you how fast glaciers can grow.
Oh, how I miss him calling the great Big Ten games on ABC, blimp overhead. "Ohio State about to lose to Michigan..."
He can't be replaced in our lifetimes. Although he is 'retired' nothing makes a game like Mr. Jackson.
LOL!
Now, if I had been enjoying a beverage, then you would owe a new screen to me.
Actually, it's from landfills with an excess of decomposing organic materials, mostly buggy whips I'm told. /sarc/humor
Remember, all this and we have NO SALES TAX here. Great for fixed incomes. I am hoping more conservatives will retire here, and we can take BACK our state!
I was thinking that Mt. Hood was losing ice because Texans were having a cocktail party near it.

Don't worry. When Mt. Hood blows, there won't be any glaciers left. Just like Mt. St. Helens doesn't have glaciers anymore.
