All over Alaska, heat from roadways and buildings is causing the ice in unstable permafrost formations to melt, creating serious issues for the safety and longevity of Alaskan infrastructure. Lying beneath as much as 85% of Alaska, the majority of structures across the state are built on top of the permafrost layer, which has grown increasingly unstable with the advent of global warming. Ed Yarmak, the president of Arctic Foundations, states, “If you’re going to put a building on permafrost, unless the permafrost is thaw stable, which most of it isn’t, your building is going to settle.” This settling and destabilization of the earth is projected to raise the cost of maintaining affected public infrastructure by 10-20 percent ($4-6 billion) by 2030 and another 10-20 percent ($5.6-7.6 billion) by 2080 …show more content…
Passive thermosiphons operate without external power, utilizing the vaporization of a pressurized gas in its liquid phase at the lower, buried end of the tube, which rises through an adiabatic middle- section and condenses on the walls of the top. This liquid, then releases its latent heat to the wall (and thus the outside air), cools and runs back down to the bottom of the tube by gravity. Passive thermosiphons are the most common in Alaska, but are limited by their inability to withdrawal heat from the ground when it is cooler than the air temperature. While this may be a serious limitation in warmer climates, the temperature during the winter in central Alaska typically hovers around -15 to -25 °F (-26 to -32 °C), so ground temperature can be greatly reduced during the winter. Additionally, during summer nights, temperatures can get cold enough for thermosiphons to function, aiding in the refreezing of permafrost. Hybrid and active thermosiphons use a heat pump to cool the ground during times when the air is warmer than it, increasing their effectiveness, but also requiring an energy
The Blizzard of 1978 was a disaster because it caused so many issues for more than 3 states. Illinois, Indiana, Kentucky, Michigan, Ohio, and Southwest Wisconsin were all affected by the high winds of 100 miles per hour and 40-60 inches of snow. Also, some homes’ roofs were torn apart and fell in the home. This killed more than 400 people, buried in 27 feet of snow or more. Weather stations had to readjust their weather chart due to pressures falling below the chart scale. This nearly caused a hurricane to happen. Other regions only saw over a foot of snow from the storm.
The Alaskan climate means that it has hundreds of miles of permafrost areas, which are areas of frozen soil that stay at temperatures below the freezing point of 32 degrees Fahrenheit or zero degrees Celsius all year long.
Imagine a place where where around 300,000 people live in the future, in a moderate to intense climate. Frost Forest, Alaska would be the perfect place to live.The city makes up 47% of the Alaska's employment. It has so much to offer, we have many green open spaces to run, jog, play, and to sightsee in. Frost forest has all sorts of greenery there are 1,700 types of them. Lichen, bearberries, and Forget-me-not are just a few examples!
Farge has been tracking glaciers in Glacier National Park for 25 years. The degrading ice fields are measured and photographed often. A once famous Boulder Glacier has been left to slush, with the same still happening to many Glaciers. In the park 50 glaciers existed in the mid nineteen fifties, now only 25 are left. In 1977 Gore made a speech on Grinnell Glacier about climate change. With the once 15-20 foot drop they were worried about falling ice. Today, the drop isn’t even to your kneecap. Cloud Glacier Peak is predicted to die in 2035. The decline has led to a loss of homes for many species. Animals that live near glacier edges enjoyed the conditioned temperatures, are now losing that. With the loss of these Glacier sea levels are rising
Why should we care is a question that many people end up asking. Earth’s average temperature has increased by at least 2 degrees Fahrenheit in the past century and scientists expect it to go up to about 12 degrees Fahrenheit in the next. To us, those numbers seem quite small, but the average temperature a couple centuries ago was 4 degrees lower than it is today, allowing ice caps to stay ice caps. As the temperature increases, ice caps start to melt resulting in the rising of sea levels. With the sea rising, storms are becoming more and more frequent and stronger. High sea levels also cause torrential rains and flooding which threatens us as humans, wildlife and nature.
The Rocky Mountains, on the border of the provinces of Alberta and British Columbia, has many attractions for tourists. One attraction is the Columbia Icefield. This huge field of ancient ice cover 125 square kilometers. The Athabasca, Stutfield and Dome glaciers make up the ice field. As the ice melts, the water flow into four major river systems. These systems is the Columbia, Fraser, Mackenzie and Saskatchewan. The meltwater flows down these rivers into three different oceans, the Pacific, Arctic and Atlantic. This high point in a continent's water system is called a"hydrological apex", and the Columbia Icefield is one of only two such apexes in the world. Tourists visit the icefield from April to October each year. Walking
Ice Mountain is a place of beauty and rarity. All four of the systems of the earth, the geosphere, hydrosphere, atmosphere, and biosphere, helped to contribute to make Ice Mountain the rare astounding piece of our collective geoheritage that it has become. Ice Mountain’s creation and uses helps make it one of the most interesting and important mountains in West Virginia that has been impacted by many earth systems throughout history. Ice Mountain is very important to the biosphere. It provides habitats for breeding warblers, thrushers, vireos, as well as several other important types of birds. It also carries several species of arboreal plants from starflowers to hemlocks. Eastern hemlocks help to cool the ice vents, which help to cool the mountain and give it its name of Ice Mountain.
This report focuses on an event that occurred a long time ago, known as the Little Ice Age. A description of what it is, how it began, how long it lasted, whether it was instantaneous or consistent over time, and how it is related to climate change are included in this paper. What the cause for the Little Ice Age and its effects and impact on society in the past, present, and future are discussed. Furthermore, the positive and negative feedback loops part of the Little Ice Age are addressed, and any future projections of an event similar to this are also talked about. Finally, a drawing of the various interactions between the event and each sphere of the Earth- the Hydrosphere, Biosphere, Lith¬osphere, Atmosphere- is included towards the end of the report. There are two interactions for each sphere. A conclusion wrapping all that was discussed in the report is encompassed within this paper. The Little Ice Age and its relation and impact on the climate and the Earth System are the major focus of this report.
The Ice Age was the mark of the extinction of life in that time. What was the end result would lead to many discoveries by man that is still to this day yielding more data, information on what happened in that time. Living organisms being trapped in the asphalt for 11,000 to 50,000 years being perfectly preserved in rocks. The oldest of the fossils according to La Brea Tar Pits museum, that dire wolves, saber-toothed cat from Pit 91 each dated back to 44,000 years old. An coyote from Pit A is dated 46,000 years these dates estimated based on carbon-14 remains of specimens [Tarpits.org]. The whole museum ( and Los Angeles) was a crucial discovery point, the underground reveals hundreds of thousands of fossils perfectly in an protective shell from the Ice Age. In the 19th century a lake was mined at Rancho La Brea in Los Angeles the museum has a vast examples of what transpired with the fossils as the blueprint to history.
I am doing my Current Events in Science about ice caves and on last February 11,000 people went to Wisconsin to see the ice caves. These caves were big enough to fit at least 50 people inside! The caves are in the Apostle Islands National Lakeshore in Wisconsin. They get a lot of people’s attention each year. The Apostle Islands have a least 21 islands and some are big and some are small.
The ice age has covered most of north America and has carved out numerous lakes. The glacier was a 100-foot high flow of ice and snow. Remnants of these large sheets of ice can still be seen today in the form of numerous lakes and the most brilliant of them are the Great Lakes. Other, larger ones, such as Lake Winnipeg, Reindeer, Athabaska, Great Slave, and Great Bear in Canada, existed at one time but have since drained off and have disappeared. Glaciers reached as far south as the locations now of the Ohio and Missouri Rivers. Sea levels fell approximately 425 feet with so much water diverted from the natural cycle to form the ice on the glacier. It uncovered the flat continental shelves as dry land. It had the same
i like this album a lot it’s very dark and morbid it has this “yeah i’m going to die but…. im cool with it” aesthetic surrounding the whole project the vocals can be very soothing yet very haunting and intense it sounds like it’s in the middle of the process of dieing like you’re reaching for the light!!! but you can’t quite reach it no matter how far you extend your arms so much to the point you start wiggling your fingers kinda like when you drop something just outta your reach you try and you hardest just to tap it in hopes of bringing it closer to you now apply that to the subject of life,death,love and happiness that’s what you have here it’s a really dope beautiful work of art
Looking for a Calgary Snow Removal NE Service? Well, now is the time to start your search for the right snow removal service. Time and time again, most people wait till they are in the middle of a big snowstorm or blizzard before they even think about hiring a snow removal company. Well, it is just a part of human nature to wait until the last minute to do the right thing. The fact is that hiring a snow removal crew under tremendous pressure due to an impending storm leads to making vital mistakes. Therefore, it is important to think ahead, before storm warnings approach.
Glaciers is familiar to most people, thinking as a big rigid piece of ice. However, under pressure, glaciers act like a soft plastic. They can bend and flow downhill like slow-motion river of ice. However, ice caps, ice sheets and really any masses of ice which remain year round are also considered glaciers. For typical glacier, snowfall builds up on its surface. Overtime, all the layers of snow press down on the layers beneath compacting the snow crystals into ice. This ice form the main body of the glaciers. Glaciers gain ice from snowfall. They lose ice through surface melting, melting from beneath and in some cases, by gradually flowing into lakes or oceans and breaking off into icebergs. In winter, new snow weighs down of the glacier pushing
What is dry ice? Dry ice is the solid form of carbon dioxide, and it is sometimes called "cardice". Dry ice is extremely cold ranging from temperatures like -109.3°F or -78.5°C. At this temperature, it sublimates from a solid state into a gaseous state and/or undergoes deposition from a gas to a solid form. In order for dry ice to form liquid carbon dioxide, it needs to be placed in a high-pressure area or environment. The first published observation of dry ice was in 1835 by French chemist by the name of, Charles Thilorier. He noted the formation of dry ice when a container of liquid carbon dioxide was opened, and released into the air. Dry ice resembles snow or water ice. It's usually sold as chunks or pellets, which appear white because
