(Credit: Image courtesy of University at Buffalo)ScienceDaily (Feb. 12, 2008) — A comprehensive new study authored by University at Buffalo scientists and their colleagues for the first time documents in detail the dynamics of parts of Greenland's ice sheet, important data that have long been missing from the ice sheet models on which projections about sea level rise and global warming are based.

The research also demonstrates how remote sensing and digital imaging techniques can produce rich datasets without field data in some cases.

Traditionally, ice sheet models are very simplified, according to Beata Csatho, Ph.D., assistant professor of geology in the UB College of Arts and Sciences and lead author of the paper.*

"Ice sheet models usually don't include all the complexity of ice dynamics that can happen in nature," said Csatho. "This research will give ice sheet modelers more precise, more detailed data."

The implications of these richer datasets may be dramatic, Csatho said, especially as they impact climate projections and sea-level rise estimates, such as those made by the United Nations Intergovernmental Panel on Climate Change (IPCC).

"If current climate models from the IPCC included data from ice dynamics in Greenland, the sea level rise estimated during this century could be twice as high as what they are currently projecting," she said.

The paper focuses on Jakobshavn Isbrae, Greenland's fastest moving glacier and its largest, measuring four miles wide.

During the past decade, Jakobshavn Isbrae has begun to experience rapid thinning and doubling of the amount of ice it discharges into Disko Bay.

"Although the thinning started as early as the end of the 18th century, the changes we are seeing now are bigger than can be accounted for by normal, annual perturbations in climate," Csatho said.

In order to document the most comprehensive story possible of the behavior of Jakobshavn Isbrae since the Little Ice Age in the late 1800s, Csatho and her colleagues at Ohio State University, the University of Kansas and NASA used a combination of techniques.

These included field mapping, remote sensing, satellite imaging and the application of digital techniques in order to glean "hidden" data from historic aerial photographs as many as 60 years after they were taken.

By themselves, Csatho explained, the two-dimensional pictures were of limited value.

"But now we can digitize them, removing the boundaries between them and turning several pictures into a single 'mosaic' that will produce one data set that can be viewed in three-dimensions," she said.

"By reprocessing old data contained in these old photographs and records, we have been able to construct a long-term record of the behavior of the glacier," said Csatho. "This was the first time that the data from the '40s could be reused in a coherent way."

The data from the historic photos were combined with data from historical records, ground surveys, field mapping and measurements taken from the air to document important signs of change in the glacier's geometry.

Csatho explained that conventional methods of assessing change in glaciers have depended on documenting "iceberg calving," in which large pieces at the front of the glacier break off.

"But we found that you can get significant changes in the ice sheet without seeing a change in front," she said.

Other key findings of the paper are that two different parts of the same glacier may behave quite differently and that a glacier does not necessarily react to climate change as a single, monolithic entity.

"Climate forces are complex," Csatho said. "For example, we found that the northern part of Jakobshavn was still thinning while the climate was colder between the 1960s and the 1990s."

Csatho, who is a geophysicist, added that the research is the result of a strong interdisciplinary team involving experts in glaciology, ice sheet modeling and photogrammetry, the science of making measurements based on photographs.

This research was published online in February 2008 in the Journal of Glaciology. Csatho's co-authors on the paper are Tony Schenk of the Ohio State University Department of Civil and Environmental Engineering and Geodetic Science; Kees van der Veen of the Center for Remote Sensing of Ice Sheets at the University of Kansas, and William B. Krabill of the National Aeronautics and Space Administration's Cryospheric Sciences Branch.

“Larsen B, the B sector of the Larsen Ice Shelf, which collapsed in Antarctica during February of 2002 was estimated to be 220 metres thick and 3250 kilometres square (weighing 720 billion tonnes)… that is…. 722 ft thick, 1255 square miles (a square over 35 miles on a side), weighing 793,664,143,900 tons.

From 1997 through 2002, the shelf lost a total of 5700 square kilometers (2200 square miles), and was about 40 percent the size of its previous minimum stable extent.

Overall in the Antarctic Peninsula, the seven ice shelves declined by a total of about 13500 square kilometers (43800 square miles) from 1974 to 2002.

“Okay so you go to a doctor who gets some test and tells you "You are dying unless you spend exhorbitant amounts of money to save yourself."

So after a few years of being told you are dying and making radical changes you find the original test was inaccurate....you would and should sue his ass off.

Feb. 20 (Bloomberg) -- A glitch in satellite sensors caused scientists to underestimate the extent of Arctic sea ice by 500,000 square kilometers (193,000 square miles), a California- size area, the U.S. National Snow and Ice Data Center said.

The error, due to a problem called “sensor drift,” began in early January and caused a slowly growing underestimation of sea ice extent until mid-February. That’s when “puzzled readers” alerted the NSIDC about data showing ice-covered areas as stretches of open ocean, the Boulder, Colorado-based group said on its Web site.

Granted they back this by saying it really doesn't change the "overall estimate" but you combine this with other reports of screwed up estimates......”

“Is it MAN or normal occurrences? The truth is Rosey there is NOTHING that proves we have had one wit of impact on the world envrionment (that is scientifically reproducible) there are normal "cycles" of nature.

There was a Little Ice Age that ended in the 1880s or something meaning...(like when winter ends) it will get WARMER. BUT its like the doctor telling you to make radical lifestyle changes becuase he read tea leaves.”

“Lets keep the GW going so we don't make the mistake of thinking about the polution in our own homes and gardens, not to mention the work place.”

“Then give solutions to fight pollution. The recommended solutions for fighting global warming do not fight pollution. Carbon credits will just move industrial strength pollution to 3rd world countries. They will wipe out wetlands and rainforest in order to build these industries and to provide crops for biofuels. Most people who oppose these solutions aren't for dirty air and more pollution, we just don't think they will work the way proponents think they will.”

“My point is that GW has taken a simple problem to almost religious status and the carbon credit crap wouldn't have a chance if solutions became local instead of getting the federal government involved with it's troops of lobbyist from every international corps that exist.”

“More reasons not to believe in global warming
Genesis 9
11 I am making my promise to you. Never again will all life be killed by floodwaters. Never again will there be a flood that destroys the earth." 12 God said, "This is the sign of the promise I am giving to you and every living being that is with you for generations to come. 13 I will put my rainbow in the clouds to be a sign of my promise to the earth. 14 Whenever I form clouds over the earth, a rainbow will appear in the clouds. 15 Then I will remember my promise to you and every living animal. Never again will water become a flood to destroy all life. 16 Whenever the rainbow appears in the clouds, I will see it and remember my everlasting promise to every living animal on earth." 17 So God said to Noah, "This is the sign of the promise I am making to all life on earth."”
