In Alaska, 35 percent forest, climate change is causing irreversible changes including droughts, forest fires, and infestations of tree-killing insects like spruce beetles and spruce budworm moths. In the last 15 years, the spruce beetles, which thrive in warmer climates, have destroyed a total of about 3 million acres (1.21 million hectares) of spruce forest in south-central Alaska.
Large wildfires that began in July continued to burn in interior Alaska in the first week of August 2009. These images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite on August 2 show some of the state’s largest blazes and the thick pall of smoke they were creating. The top image is a natural-color (photo-like) view of the area, while the lower image combines visible, shortwave-, and near-infrared light to make burned areas (brick red) stand out better from unburned vegetation (bright green). In this kind of false-color image, the bright pink areas along the perimeters of the fires are often a sign of open flame.
According to the August 3 report from the Alaska Interagency Coordination Center, 483 fires were burning across the state, affecting about 2.4 million acres. The Railbelt Complex was the largest at an estimated 462,298 acres. The Tanana River appears to be creating a natural firebreak at the northern edge of the fire, which is spreading to the south. To the east, the smaller Wood River Fire (107,634 acres) has bright pink spots along both its northern and southern perimeters. Both these fires, as well as the Big Creek Fire (145,652 acres) and Little Black One Fire (292,907 acres) along the Yukon River, were triggered by lightning.

Alaska has experienced an average warming of 3 degrees Celsius (5.4 °F) and about 4.5 °C (8°F) in the inner regions in winter months since the 1960s, the largest regional warming of anywhere in the U.S., according to records.
The warmer temperature means Alaska’s peat bogs, which are nearly 14,000 years old, are drying up. Ed Berg, an ecologist for the U.S. Fish and Wildlife Service, has discovered that shrubs and other plants have been rooting in areas of peat big normally too soggy for woody plants to grow during the last three decades.
As the areas of beetle-infested forest grow, more land is clear-cut and land speculation frenzy grows.
Wetlands are a natural defense mechanism retarding forest fires. The warmer weather and drier forest therefore could lead to more forest fires.
Drying or burning peat bogs, which comprise 50-60 percent carbon, would release additional carbon dioxide, the principal greenhouse gas, to the atmosphere.

Several types of rocks that are abundant in the U.S. may one day be charmed to absorb carbon dioxide at such phenomenal rates that could retard climate change, global warming retardation experts say.
But don’t we all know that? Rocks naturally absorb carbon dioxide, but the binding process takes thousands of years to form minerals like calcium carbonate.
Oh, but the process can be accelerated in the laboratory using a catalyst like sodium citrate.
“One day this could be an incredibly useful tool to help fight global warming,” said Sam Krevor, the lead author of a new study by scientists at Columbia University’s Earth Institute and the U.S. Geological Survey that maps such rocks in the United States, Reuters reported.
But that process occurs on too small a scale naturally and requires too much energy and other inputs to tackle the vast volumes of carbon dioxide responsible for the greenhouse effect that is causing global warming.
What are we waiting for? Errr … the rocks must first be crushed to a powder to absorb larger amounts carbon dioxide!
And to repeat the laboratory process on any scale larger than the contents of test tube, you would need tremendous amount of energy to reduce the carbon dioxide in the atmosphere.
At about $45-dollar-a-barrel (crude oil April delivery NYME ), doesn’t it make sense to buy all the energy needed to absorb all the CO2 possible, right now?
About 15,540 sq km (6,000 square miles) of rocks that are rich in carbon dioxide absorbing minerals, namely olivine and serpentine, could be supercharged to absorb carbon dioxide in California, Oregon and Washington, “and along the entire Appalachian belt of eastern North America from Alabama to Newfoundland,” the study suggests.
What about more research on this exciting new [sic] possibility?
The experts need more money.
Isn’t this a good time to get more money, with the stimulus package …?
Krevor believes the U.S. rocks could potentially absorb the equivalent of 500 years’ of the nation’s CO2 emissions. The United States is the world’s second-largest carbon dioxide emitter after China.
“The problem is not going to be a lack of rocks, it’s getting them to do the job,” Krevor said.
Well said, Dr. Haven’t they yet issued you with a magic wand, or a copy of Essenian Dead Sea scroll for the spells?

Our regular readers probably remember Thought for the Day: A 2009 Forecast AND
The first of the ‘surprises’ in 2009 is a BIG one!
Global Warming is occurring at a faster rate than scientists had predicted, according to a climate scientist.
“The consequence of that is we are basically looking now at a future climate that is beyond anything that we’ve considered seriously,” Chris Field, a climate scientist and a member of the Intergovernmental Panel on Climate Change, or IPCC, said on saturday.
Smoke billows from an iron and steel plant in Hefei, Anhui province December 9, 2007. All nations must do more to fight climate change, and rich countries must make deep cuts in greenhouse gas emissions to avoid the worst impacts, a draft proposal at United Nations talks said on Saturday. REUTERS/Jianan Yu (CHINA). Image may be subject to copyright.
Field reported that “the actual trajectory of climate change is more serious” than any previously predicted in the IPCC’s fourth assessment report named “Climate Change 2007.”
“He said recent climate studies suggested the continued warming of the planet from greenhouse gas emissions could touch off large, destructive wildfires in tropical rain forests and melt permafrost in the Arctic tundra, releasing billions of tons of greenhouse gasses that could raise global temperatures even more.” Reuters reported.
“There is a real risk that human-caused climate change will accelerate the release of carbon dioxide from forest and tundra ecosystems, which have been storing a lot of carbon for thousands of years,” Field said.
“We now have data showing that from 2000 to 2007, greenhouse gas emissions increased far more rapidly than we expected, primarily because developing countries, like China and India, saw a huge surge in electric power generation, almost all of it based on coal,” Field added.

1. Researchers from the U.S. and Canada say prolonged droughts and warmer temperatures, which help pine beetles and other organisms to destroy trees, seem to be quickening the pace of the forests death.
2. “Average temperature in the West rose by more than 1 degree F [1.8ºF=1ºC] over the last few decades,” said Phillip van Mantgem of the U.S. Geological Survey, who participated in the study.
Gray, needleless limber pine, the likely victims of drought, interspersed with orange, dead limber and ponderosa pine killed by Rocky Mountain pine beetles in Colorado’s Rocky Mountain National Park are seen in this undated photo. REUTERS/Jeremy Smith/University of Colorado handout.
3. “While this may not sound like much, it has been enough to reduce winter snowpack, cause earlier snowmelt, and lengthen the summer drought.”
4. The study, which was published in the journal Science reports that different species of trees of varying ages and sizes are dying quicker, regardless of forest elevation.
5. The reports findings are consistent with other research and observation, including the destruction of about 1.5 million hectares of pine forest by mountain pine bark beetles in northwestern Colorado, Reuters reported.
6. “We need to consider developing land-use policies that reduce the vulnerability of people and resources to wildfires,” Thomas Veblen of the University of Colorado said.
7. “Activities include reducing residential development in or near wildland areas that are naturally fire-prone and where we expect fire risk to increase with continued warming.”
8. “We may only be talking about an annual tree mortality rate changing from 1 percent a year to 2 percent a year, an extra tree here and there,” Mark Harmon, a professor of forest ecology at Oregon State University said.
9. “Forest fires or major insect epidemics that kill a lot of trees all at once tend to get most of the headlines. What we’re studying here are changes that are much slower and difficult to identify, but in the long run extremely important.”

WILKINS ICE SHELF, Antarctica (Reuters) – A huge Antarctic ice shelf is on the brink of collapse with just a sliver of ice holding it in place, the latest victim of global warming that is altering maps of the frozen continent.
Between 1981 and 2007, most of Antarctica warmed. Portions of West Antarctica experienced an especially rapid rise in temperature. (NASA image by Robert Simmon, based on data from Joey Comiso, GSFC.)
“We’ve come to the Wilkins Ice Shelf to see its final death throes,” David Vaughan, a glaciologist at the British Antarctic Survey (BAS), told Reuters after the first — and probably last — plane landed near the narrowest part of the ice.
The flat-topped shelf has an area of thousands of square kilometers, jutting 20 meters (65 ft) out of the sea off the Antarctic Peninsula.
But it is held together only by an ever-thinning 40-km (25-mile) strip of ice that has eroded to an hour-glass shape just 500 meters wide at its narrowest.
In 1950, the strip was almost 100 km wide.
“It really could go at any minute,” Vaughan said on slushy snow in bright sunshine beside a red Twin Otter plane that landed on skis. He added that the ice bridge could linger weeks or months.
The Wilkins once covered 16,000 sq km (6,000 sq miles). It has lost a third of its area but is still about the size of Jamaica or the U.S. state of Connecticut. Once the strip breaks up, the sea is likely to sweep away much of the remaining ice.
Icebergs the shape and size of shopping malls already dot the sea around the shelf as it disintegrates. Seals bask in the southern hemisphere summer sunshine on icebergs by expanses of open water.
High-resolution satellite data show the Wilkins Ice Shelf collapse in detail, including blocks of ice that have tipped over and blocks of ice that have remained upright. (Formosat image © 2008 Dr. Cheng-Chien Liu, National Cheng-Kung University and Dr. An-Ming Wu, National Space Organization, Taiwan.)
A year ago, BAS said the Wilkins was “hanging by a thread” after an aerial survey. “Miraculously we’ve come back a summer later and it’s still here. If it was hanging by a thread last year, it’s hanging by a filament this year,” Vaughan said.
Nine other shelves have receded or collapsed around the Antarctic peninsula in the past 50 years, often abruptly like the Larsen A in 1995 or the Larsen B in 2002. The trend is widely blamed on climate change caused by heat-trapping gases from burning fossil fuels.
WARMING TO BLAME
“This ice shelf and the nine other shelves that we have seen with a similar trajectory are a consequence of warming,” Vaughan said.
In total, about 25,000 sq km of ice shelves have been lost, changing maps of Antarctica. Ocean sediments indicate that some shelves had been in place for at least 10,000 years.
Early in the day on February 28, 2008, the Wilkins Ice Shelf remained intact. By March 17, 2008, the ice shelf had retreated significantly from its original extent. As the Antarctic summer drew to a close, sea ice began to freeze around the ice fragments. (NASA images by Jesse Allen and Robert Simmon, based on MODIS data.)
Vaughan stuck a GPS monitoring station on a long metal pole into the Wilkins ice on behalf of Dutch scientists. It will track ice movements via satellite.
The shelf is named after Australian George Hubert Wilkins, an early Antarctic aviator who is set to join an exclusive club of people who have a part of the globe named after them that later vanishes.
Loss of ice shelves does not raise sea levels significantly because the ice is floating and already mostly submerged by the ocean. But the big worry is that their loss will allow ice sheets on land to move faster, adding extra water to the seas.
Large blocks of ice, recently broken off the Wilkins Ice Shelf, float on the ocean in this aerial photograph. In between the large blocks of ice float much smaller pieces of ice with a rough surface. (Photograph © 2008 British Antarctic Survey.)
Wilkins has almost no pent-up glaciers behind it. But ice shelves further south hold back vast volumes of ice. “When those are removed the glaciers will flow faster,” Vaughan said.
Temperatures on the Antarctic Peninsula have warmed by about 3 Celsius (5.4 Fahrenheit) since 1950, the fastest rise in the southern hemisphere. There is little sign of warming elsewhere in Antarctica.
BAS scientists and two Reuters reporters stayed about an hour on the shelf at a point about 2 km wide.
“It’s very unlikely that our presence here is enough to initiate any cracks,” Vaughan said. “But it is likely to happen fairly soon, weeks to months, and I don’t want to be here when it does.”
The U.N. Climate Panel, of which Vaughan is a senior member, projected in 2007 that world sea levels were likely to rise by between 18 and 59 cm (7 and 23 inches) this century.
But it did not factor in any possible acceleration of ice loss from Antarctica. Even a small change in the rate could affect sea levels, and Antarctica’s ice sheets contain enough water in total to raise world sea levels by 57 meters.
About 190 nations have agreed to work out a new U.N. treaty by the end of 2009 to slow global warming, reining in emissions from burning fossil fuels in power plants, cars and factories.
Following are facts about ice shelves.

From NASA with Love!
December 5, 2008
The Internet is full of references to global warming. The Union of Concerned Scientists [aka, the snakeoil merchants] website on climate change is titled “Global Warming,” just one of many examples. But we don’t use global warming much on this website. We use the less appealing “climate change.” Why?
By any other name … Whether referred to as “global warming” or “climate change,” the consequences of the widescale changes currently being observed in Earth’s climate system could be considerable.
To a scientist, global warming describes the average global surface temperature increase from human emissions of greenhouse gases. Its first use was in a 1975 Science article by geochemist Wallace Broecker of Columbia University’s Lamont-Doherty Geological Observatory: “Climatic Change: Are We on the Brink of a Pronounced Global Warming?”
Broecker’s term was a break with tradition. Earlier studies of human impact on climate had called it “inadvertent climate modification.” This was because while many scientists accepted that human activities could cause climate change, they did not know what the direction of change might be. Industrial emissions of tiny airborne particles called aerosols might cause cooling, while greenhouse gas emissions would cause warming. Which effect would dominate?
For most of the 1970s, nobody knew. So “inadvertent climate modification,” while clunky and dull, was an accurate reflection of the state of knowledge.
The first decisive National Academy of Science study of carbon dioxide’s impact on climate, published in 1979, abandoned “inadvertent climate modification.” Often called the Charney Report for its chairman, Jule Charney of the Massachusetts Institute of Technology in Cambridge, declared: “if carbon dioxide continues to increase, [we find] no reason to doubt that climate changes will result and no reason to believe that these changes will be negligible.”
In place of inadvertent climate modification, Charney adopted Broecker’s usage. When referring to surface temperature change, Charney used “global warming.” When discussing the many other changes that would be induced by increasing carbon dioxide, Charney used “climate change.”
Within scientific journals, this is still how the two terms are used. Global warming refers to surface temperature increases, while climate change includes global warming and everything else that increasing greenhouse gas amounts will affect.
Definitions:
Global warming: the increase in Earth’s average surface temperature due to rising levels of greenhouse gases.
Climate change: a long-term change in the Earth’s climate, or of a region on Earth.
During the late 1980s one more term entered the lexicon, “global change.” This term encompassed many other kinds of change in addition to climate change. When it was approved in 1989, the U.S. climate research program was embedded as a theme area within the U.S. Global Change Research Program.
But global warming became the dominant popular term in June 1988, when NASA scientist James E. Hansen had testified to Congress about climate, specifically referring to global warming. He said: “global warming has reached a level such that we can ascribe with a high degree of confidence a cause and effect relationship between the greenhouse effect and the observed warming.” Hansen’s testimony was very widely reported in popular and business media, and after that popular use of the term global warming exploded. Global change never gained traction in either the scientific literature or the popular media.
But temperature change itself isn’t the most severe effect of changing climate. Changes to precipitation patterns and sea level are likely to have much greater human impact than the higher temperatures alone. For this reason, scientific research on climate change encompasses far more than surface temperature change. So “global climate change” is the more scientifically accurate term. Like the Intergovernmental Panel on Climate Change, we’ve chosen to emphasize global climate change on this website, and not global warming.
