Alaska's retreating glaciers seen as evidence Earth is warming


We are fooling ourselves if we assume that increased surface heating of parts of the Earth from "global" warming can not increase severe weather of all kinds including tornadoes (2004 shattered previous record), blizzards, frosts and freezes (year-round) and EXTENDED cold spells and, "paradoxically," the differential heating and cooling imbalance can quite plausibly help iniatiate the transition from interglacial to glacial periods, if the soils of the Gaiasphere are seriously demineralized/acidified, as at present (typical late-interglacial ecological conditions, yet further depleted by 6 billion "takers").

Are any of you still not aware of the free books by John Hamaker and myself at http://www.remineralize.org You may go there and read the synopses and decide if you'd like to download the books. At the least I think you will find they can help us all think more holistically...

Don't be fooled by this weekend's cold spell (in the Midwest). Global warming is still alive and growing stronger.

SCIENCE: Photos prove that glaciers are dwindling



(Published: January 9, 2005)

SAN FRANCISCO -- People picked up their newspapers on thousands of doorsteps in this city recently and saw two pictures of Glacier Bay on the front page, under the headline "Alaska's retreating glaciers seen as evidence Earth is warming."

One photo provided by glaciologist Bruce Molnia showed Muir Glacier in 1941. Molnia compared it to a photo he took in 2004 that shows Muir Glacier's retreat out of the picture in 60 years.

About 15 national reporters attended a press conference on the disappearing glaciers and other changes in Alaska's landscape at the American Geophysical Union's annual meeting in San Francisco, which this year attracted more than 11,000 scientists. Joining Molnia as a speaker were Matt Nolan of UAF's Water and Environmental Research Center and Ken Tape of the Geophysical Institute. Nolan showed his photos of shrinking McCall Glacier in the Brooks Range and Tape showed photos of how the Arctic has gotten shrubbier from the 1940s to the present.

Reporters scribbled notes as they looked at the images, which show how quickly the North has warmed in the last century, especially the last 50 years.

"When you put pictures in front of somebody, you don't have to say anything," said Molnia, who works for USGS in Reston, Va., but has a home in Fairbanks. Molnia spent the summer of 2004 traveling to Glacier Bay and Kenai Fjords, trying to find the exact spots where earlier photographers captured glaciers on film. Sometimes finding the cairns (rock piles) of glaciologists who took photographs from the spots decades earlier, Molnia snapped new photos, including the color one of Muir and Riggs glaciers that appeared on the front page of the Dec. 17, 2004, San Francisco Chronicle and accompanied a story about Alaska's melting glaciers by David Perlman.

Nolan showed his comparison of McCall Glacier, featuring a photo taken by glaciologist Austin Post in 1958 along with a photo Nolan snapped with his pocket-size digital camera in 2003.

"All the glaciers in the Arctic National Wildlife Refuge are retreating from their most extended positions thousands of years ago, and the only scientific explanation is climate change," said Nolan, as quoted by Perlman in the Chronicle article.

Tape took the laser pointer and displayed several pairs of photos of Alaska's North Slope that show the encroachment of shrubs. A government photographer took the huge-negative, Ansel-Adams style black and white originals in the 1940s, and Tape duplicated them with a digital camera in recent years. He explained how shrubs make the North Slope warmer by absorbing more sunlight and how shrubs along riverbanks have restricted river channels and perhaps attracted more moose north over the Brooks Range. The changes he has detailed along with Matt Sturm and Charles Racine of the Cold Regions Research and Engineering Laboratory have all happened in about 60 years, "a blink of an eye in geological time," Tape said.

The use of photographs to document change in the North is a technique more scientists are using, enough that it merited a poster session on the subject at the conference. Molnia said his future work includes revisiting about 100 of the places in Denali National Park that mountaineer and photographer Brad Washburn photographed in the 1930s and 1940s to compare changes from then until now. Molnia tried to duplicate them in the summer of 2004, but the air was too smoky. Along with documenting changes in Alaska Range glaciers, Molnia will also benefit from changes in technology since Washburn climbed the peaks.

"Brad used 60-pound cameras for his work," Molnia said. "We'll do a lot of our stuff with digital cameras."
