Alaskan Glaciers Growing
I know, it's shocking, isn't it? Simply so contrary to what Global Warming Alarmists like Albert Gore, Junior and Will Steger have been saying.
It's unlikely we'll see either of them reporting on this story.
From Anchorage Daily News:
Unusually large amounts of winter snow were followed by unusually chill temperatures in June, July and August.
"In mid-June, I was surprised to see snow still at sea level in Prince William Sound," said U.S. Geological Survey glaciologist Bruce Molnia. "On the Juneau Icefield, there was still 20 feet of new snow on the surface of the Taku Glacier in late July. At Bering Glacier, a landslide I am studying, located at about 1,500 feet elevation, did not become snow free until early August.
"In general, the weather this summer was the worst I have seen in at least 20 years."
Never before in the history of a research project dating back to 1946 had the Juneau Icefield witnessed the kind of snow buildup that came this year. It was similar on a lot of other glaciers too.
"It's been a long time on most glaciers where they've actually had positive mass balance," Molnia said.
That's the way a scientist says the glaciers got thicker in the middle.
[...]
"All it takes is a warm summer to have a really dramatic effect on the melting.''
Or a cool summer to shift that mass balance the other way.
One cool summer that leaves 20 feet of new snow still sitting atop glaciers come the start of the next winter is no big deal, Molnia said.
Ten summers like that?
Well, that might mark the start of something like the Little Ice Age.

Climate is constantly shifting. And even if the past year was a signal of a changing future, Molnia said, it would still take decades to make itself noticeable in Alaska's glaciers.
Rivers of ice flow slowly. Hundreds of feet of snow would have to accumulate at higher elevations to create enough pressure to stall the current glacial retreat and start a new advance. Even if the glaciers started growing today, Molnia said, it might take up to 100 years for them to start steadily rolling back down into the valleys they've abandoned.
"It's different time scales," he said. "We're just starting to understand."
As strange it might seem, Alaska's glaciers could appear to be shrinking for some time while secretly growing. Molnia said there are a few glaciers in the state now where constant snow accumulations at higher elevations are causing them to thicken even as their lower reaches follow the pattern of retreat fueled by the global warming of recent decades.

Hey, did you know that Al Gore was born something like 9 months almost to the day after the Rozwell New Mexico suppose "alien crash landing" in 1947, if you could July (the date of the crash being the 8th) as one of the 9 months of gestation ? Gore was born March 31 in 1949.
