What Is The Temperature, Is It Time?



Atmosphere and Al Gore's interview on Channel 9 KQED local television gave me an idea.  This is not a theory or a fact, it is only an idea that may bring more understanding to scientists and environmentalists while establishing a conversation with every person around the world.  Keep in mind your footprint, this discussion will only form a subject, the subject of atmosphere.



Mood lighting is a back to basis for the surrounding or pervading influence of any environment as the emotional tone will effect art and definitely increase or decrease the tone.  Distinct to such is the open ended definition to the word atmosphere thus creating more to rather than less than, simple mathematics.  Shape that as water in the glass yet a glass will contain the pitcher?  There is ample study on ice.

Attitude is the problem.  A problem is a figure known notoriously to the subject of Einstein's works whereas problems also are introduced to us here in the United States of America at an early age, i.e., 2 + 2 = 4.  Reminding my note to more on this is the bar of music that expresses the song, melody, verses that opera has taken to stage staggering it's audience with tears, laughter and deep emotional tone.

Swing these parts of this conversation while comprehending what the world has been doing since 'global warming' has been brought to our attention.  War foremost would inevitably be the easy blame however technology has caused many more negative reations as the instant message has brought to our everyday neighborhoods to much shock and defining horror.  Television would be also considered as the messaging of commercials or the dynamics (basic message) of every show remembering that the media stations would be separated and have to be considered per hour of information processed.

Now inviting the attention to each person that is walking, speaking, communicating the climate could be effecting the glacier, could be raising the temperature, could be the reason, it could be that simple, or, it could have been the collective as that provision would have missed this establishment of thought.


Picture Climate: What Can We Learn from Ice?

What’s the first thing that comes to mind when you hear Antarctica or Greenland? If you’re like most people, the answer is probably ice and lots of it. And it is ice that draws paleoclimatologists literally to the ends of the Earth in the quest for knowledge about where our planet has been, where it is, and where it might be going.
Ice cores provide a unique contribution to our view of past climate because the bubbles within the ice capture the gas concentration of our well-mixed atmosphere while the ice itself records other properties. At the Earth’s highest latitudes and altitudes, ice is typically the only environmental data available for scientists to reconstruct the climate hundreds to thousands of years ago.
Scientists obtain this information by traveling to ice sheets, like Antarctica or Greenland, and using a special drill that bores down into the ice and removes a cylindrical tube called an ice core. Drilling thousands of meters into ice is a feat of technology, endurance, and persistence in extreme environments, exemplified by the joint Russian, U.S., and French team that worked together to recover the iconic record of atmospheric carbon dioxide from the ice at the Russian Vostok Station in Antarctica in 1987. In 2012, Russian scientists extended the ice core to an incredible 3,768 meters, reaching Lake Vostok underneath the East Antarctic Ice Sheet.
After scientists procure the cores, they slice them up into various portions each allotted to a specific analytical or archival purpose. As the scientists are dividing the cores for analysis, they don special clean suits to prevent the core samples from becoming contaminated. Once the samples have been prepared, the scientists run a variety of physical and chemical analyses on the cores. Some of these ice procedures are consumptive, meaning their analysis requires destruction of the ice, while others have no effect on the ice. Scientists study the gas composition of the bubbles in the ice by crushing a sample of the core in a vacuum. Overall, most of the core is reserved for archival purposes, preserving a long record of Earth history for future research.
These cores have distinct layers in them that form throughout the years. With each passing year, snow falls over the ice sheets and each layer of snow has a different texture and a different chemistry, with winter snow differing from summer snow as well. During the summer, when the sun is up for 24 hours many days, the top layer of the snow changes in texture. As winter arrives and it turns cold and dark again, new snow falls on top of the summer snow forming distinct layers. Each of these layers provides scientists with a vast amount of information about the climate each year.
Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns. The thickness of each layer allows scientists to determine how much snow fell in the area during a particular year. When several cores are taken from nearby locations, scientists can also determine wind patterns based on where the snow drifted, which can be interpolated from the thickness of the layers in the cores. And, the chemical composition of the snow itself can tell scientists about the temperatures in the area as colder temperatures lead to a higher concentration of a particular oxygen isotope in the snow.
Depending on atmospheric conditions, dust from nearby locations can also accumulate in the layers of the ice cores. In addition to seasonal dust, gigantic volcanic eruptions anywhere on the globe can spew enormous quantities of dust into the atmosphere that can accumulate in the ice. All of the dust layers, combined with the chemical composition of the ice and a flow model that assesses how the ice accumulates over time allow scientists to date the age of the ice cores.
Scientists tie all of these different threads of information provided by the ice cores together and weave them into a single continuous picture of the Earth’s past climate. Visit the Ice Core page to access these data from NCDC’s Paleoclimatology Program.

Climate at the core: how scientists study ice cores to reveal Earth’s climate history

 Like a prehistoric fly trapped in amber during dinosaurs' days, airborne relics of Earth's earlier climate—including dust, air bubbles, sea salts, volcanic ash, and soot from forest fires—can end up trapped in glacial ice for eons. To climate scientists, those relics tell a story about how our planet's climate and atmosphere have changed over thousands of years.

What they find out could have an impact on worldwide civilization within a few generations—especially in coastal regions. Ice cores may reveal whether Antarctica's western ice sheet melted fully the last time Earth's climate warmed to the temperatures the planet is predicted to reach in the next two centuries. If it did, it's likely to again, which would raise sea levels significantly enough to threaten many seaside cities.
"We have some evidence that may have happened, but we aren't sure," says Erich Osterberg, who studies ice cores as an assistant professor in the Department of Earth Science at Dartmouth College.

Unlocking ice cores' secrets

To unlock the information inside an ice core, researchers in the lab may melt or crush the sample bit by bit; each deeper layer represents a slightly earlier time in the Earth's climate history. The ice arrives in small strips, about 1-by-1 inch apiece, which are smaller slices of the roughly three-foot-long, coffee-can-wide pieces a drill pulls out of a glacier.
Sometimes researchers are studying actual bubbles of the early atmosphere, trapped in the ice as it formed. To collect them, they crush the sample under a vacuum hood, which keeps other air out while they pull the newly released air into vials.
Scientists run melted samples through various instruments—mass spectrometers, scanning electron microscopes, gas chromatographs—to find tiny pieces of pollution, like sulfates, traces of metals, or radioactive fallout, or natural aerosols like dust or volcanic ash.

Because every clue in the ice, whether a grain of sea salt or an air bubble, is so miniscule and the measurements must be incredibly precise, any analysis must be done in a "clean room" setting. The researchers wear body suits and multiple layers of gloves; the room must have ultraclean filters and vents to keep the air pristine.
"Even just a fingerprint from a scientist holding the core can ruin the sample," Osterberg says.

Mystery in the melt

After analyzing enough ice core slices, which may each represent anywhere from a week to a year of time, a researcher can look for patterns to track changes in the atmosphere's composition and temperature, and what activity on Earth shaped it.
The ratio of "light" oxygen-16 to "heavy" oxygen-18 in a sample, for instance, reveals the global temperature when the ice formed; it takes colder temperatures for water vapor containing the lighter oxygen isotope to turn into precipitation. Examining the gasses trapped in ice cores is how scientists first learned that the amount of carbon dioxide and the global temperature have been linked at least the last million years of Earth's history.
Osterberg even thinks ice cores will help figure out whether Antarctica's western ice sheet melted 125,000 years ago, the last time Earth's climate warmed to the temperatures the planet is predicted to reach in the next two centuries.
Scientists hope to collect a new ice core from the eastern side of the Trans-Antarctic Mountains, which today separate the East and West Antarctic Ice Sheets. Much of the land under the West Antarctic Ice Sheet is below sea level. If the ice sheet did disintegrate, then the proposed ice core drilling location—presently in the middle of the frozen continent—would have been coastal real estate 125,000 years ago.

The West Antarctic Ice Sheet includes two massive ice shelves that extend over the Southern Ocean. If the ice west of the Trans-Antarctic Mountains melted completely 125,000 years ago, ice that today is hundreds of miles inland would have been close to sea. The right-hand part of the image is a close-up of the area around Berkner Island. Image by the NASA/GSFC Scientific Visualization Studio, based on Landsat Image Mosaic of Antarctica data.
"We would see much warmer temperatures and higher levels of sea salt reflected in the ice core chemistry if this location was hundreds of miles closer to the ocean in the past," Osterberg said.

Ice core trekkers

Before the climate fossils can tell their stories, however, they must be retrieved. Rugged researchers like Osterberg and his colleagues may spend multiple summers scoping never-before-explored areas on glaciers before trekking out to collect a core. To pick the spot, they check the ice's thickness and layers (the flatter the better) and put out GPS markers to track how quickly the ice is flowing and deforming (the slower the better).
Setting up base camp and drilling into the ice may take six to eight weeks for two cores that are each 700 feet long, Osterberg says. Some researchers, particularly in Antarctica, may drill two miles and take much longer.

"Something always goes awry," Osterberg says. "You're doing this in one of the most extreme environments you can imagine—far from help, remote, with not a lot of spare parts."
And that's before dealing with weather and wildlife.
When drilling an ice core at a remote site in Greenland in 2012, his team found out that a hurricane-strength storm was headed their way. Because their tents and equipment were high up on an unprotected, rocky ridge, the best defense would have been to move down into the valley. But they'd camped up high for a reason—warming temperatures in the region had been melting sea ice, which was driving many polar bears onto the land. The ridge was the best place to avoid them.

"We had to chose between storm and polar bear," Osterberg says. They chose storm—and lost most of their tents as a result, though help reached them in a few days.

The difficulties don't end when the core is drilled. Moving ice cores from a drilling site to the various laboratories worldwide that want a piece is a whole other challenge. The cores are usually airlifted off the top of the mountain, then shipped by air or truck in refrigerated crates, racing against the clock before they start to degrade. Precautions include paying customs officials to babysit crates on airport tarmacs and hiring a second truck to follow the first in case it breaks down.
"There's no insurance dollar you can put on it: they're priceless," Osterberg says.

The Paleoclimatology Branch at NOAA's National Climatic Data Center doesn't warehouse actual ice cores, but it is the world's largest archive of climate and paleoclimatology data. By providing a long-term, permanent home for data collected by researchers across the world, the group ensures that ice core and other ancient climate data is available to all scientists who are trying to understand and model climate and environmental changes that occur over hundreds or thousands of years.
