Chasing Ice is a documentary on melting glacier and letting the people know what is going on. This documentary was produced in 2012 directed by Jeff Orlowski. This documentary is very good on their facts. They had experts that backed up every statistic and facts they had to say. They also, had good emotional appeals, that include pictures and music. This caught people's attention as soon as James Balog showed his pictures and the reduction on the glaciers in Greenland and Iceland. James did not do much talking like he said "let my pictures do the talking" (1:02:00). The author surprises the viewers with pictures he showed but he could have used a little more fact. He had good experts but he could have used a little of experts.
We are seeing glacier from millions of year ago melt and the public not knowing what's happening. According to Dr. Martin Sharp and expert

According to James Balog he stated, "From 1902 to 2001 the glacier reduced 8 miles, but from 2001 to 2010 it doubled. It's melting faster and quicker by time" (Balog 1:08:30). The biggest glacier, the mother of all, is the glacier that people say sunk the Titanic. The assistants in the documentary witness the biggest caving event ever recorded. The size of the caving was the size of lower Manhattan, but was up to 2-3 times higher than the building in the lower part. Also, Ice land is being affected drastically due to the rapid melting of the ice sheets. According to James Balog, he stated that "The south edges of ice land are melting closer and closer to the center, which is higher into the ice sheet." (Balog40:33). This is happening when there are pools in the ice glaciers and the go through canals under the ice sheet then it gets weak and just starts to slide off the side and this is called caving. This is from the snow melting and creating these pools. It's when the Co2 is higher than the o2 in our

At first the author paints a picture of a small village or town that is getting hit by a ice storm. The narrator shows how cold it is by commenting, “But the freezing rain kept coming. Tree branches glistened like glass. Then broke like glass. Ice thickened the windows until everything outside blurred” (Heynen 1). From this the reader can tell this isn't a regular snow day. Tree branches are freezing so much that they are just breaking like glass. Also the windows have become translucent from how thick the frozen ice is on them. The narrator also states, “Some farmers went ice-skating down gravel roads” (Heynen 1). The gravel road is so frozen that a person can ice skate on it. That itself shows how cold it is outside in this story. The reader should be able to tell
Watching Miracle on Ice is a childhood memory I have a lot. The movie opens in Colorado. When watching I always felt the need to point this out. I always understood the underdog story, but it was only recently that I could clearly see the underlying themes of anti-communism.
It is predicted that the effect of permafrost melting will be that the ocean levels will rise and will significantly increase the temperature and accelerate the rate at which global warming occurs. Permafrost covers 24% of the land in the Northern Hemisphere (Insert Citation), if this was to melt 1700 gigatonnes of methane and carbon dioxide (Insert Citation), powerful heat trapping gases, would be released into the atmosphere increasing the amount of greenhouse gases by 200%.
In the story,”What Happened During the Ice Storm,” the author, Jim Heynen, utilizes imagery to develop the theme of: be a leader of kindness, not a follower of violence. “Tree branches glistened like glass. Then broke like glass.” shows the contrast between the beauty that the cold rains brought, as well as the violence that came with it. This compares to, “went ice-skating…with clubs to harvest the "pheasants…” because both begin with an innocence, and end with contrasting violence. “...looking at each other, each expecting the other to do something. To pounce on a pheasant, or to yell Bang!” Exhibits how the boys were just waiting to follow whoever acted first, whether in violence or compassion, by describing their actions of uncertainty.
The glaciers have been through a minimum of four glacial periods. They’ve been through the Little Ice age, which commenced around 4,000 years ago. Marks of retreating glacier ice are seen in the rock-strewn and sculpted peaks valleys. The land and bodies of water that the retreating ice has created a new display of animal and plant communities.
Glaciers have drastically changed over time because on average, “glaciers worldwide have been losing mass since at least the 1970s”. The melting of glaciers has been contributing to the rise in sea level because the glaciers have been shrinking faster in the last decade. Three of the major glaciers in the us have shown an overall drop in mass since the 1950s and 1960s and an accelerated rate of decline in recent years. An ice cap covered Mt. Hood during the Ice Age, from about 1.8 million years ago to about 10,000 years ago. These ice caps covered the Oregon Cascades, a series of mountains in Oregon, with glaciers going down on the east and west sides of the range. These glaciers melted into smaller glaciers as the weather proceeded to get warmer...
People are responsible for higher carbon dioxide atmosphere emissions, while the Earth is now into the Little Ice Age, or just behind it. These factors together cause many years discussions of the main sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences; even if its lead to the global warming, or to the Earth’s cooling. In their articles, “Global Warming Is Eroding Glacial Ice” by Andrew C. Revkin and “Global Warming Is Not a Threat to Polar Ice” by Philip Stott, both authors discuss these two theories (Revkin 340; Stott 344). Revkin is right that global warming is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation – all together they lead to climate changes and temperatures rising. At the same time, other factors such as deforestation contribute to environmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes.
The photographs in the book make the viewer feel as if they are witnessing the glaciers firsthand, due to the quality of the cameras that were used for the project. The woodprints showcase the minute details of the glaciers that may otherwise go unnoticed. The three artists that collaborated for this project are attempting to communicate the large impact that humans have has on glaciers, specifically those found in Glacier National Park. When the park was originally founded, in 1910, it had over one hundred and fifty glaciers. Presently, there are less than twenty-five glaciers present in the entire park.
Also I learned this information and problem from two different reliable sources and the more sources you look at the greater the chance of the information being right. I had one main reaction to what I learn about the glaciers at the park and that was I didn’t really believe it at first, because how can a big mountain of ice shrink so much that the glacier will be gone for future generations. One of the main questions that I had was “how”. After reading the article I got a better understanding of the problem and actually agree to what the article has to say.
Climate Change Reality In 1850, Glacier National Park had 150 glaciers. Now there are only 25 that remain large enough (at least 25 acres in area) to be considered functional glaciers. The park's glacially fed streams provide a constant flow of cold water throughout the summer season, maintaining necessary water levels and regulating stream temperature for fish and other species.
Not only is the loss of habitat a large problem with the melting but the issue of where does that entire melted glacier water go, is still a concern. It goes back in to the water where it started. It is important to remember that even though there was a large part of the glacier above the water, it has now melted to become part of pool below. This melting and returning to the water is causing the water levels to rise all over the world. The extra water has caused mass flooding from the rising lakes and rivers, which have drowned out homes, habitats and other areas during heavy rain.
Glaciers have disappeared due to increasing in global temperatures because of which the water level had drastically increased and its causing flood all over the world
