The article that I read was called “Is climate change shrinking glaciers? Likelihood is 99 percent”. The author of the article was Mindy Weisberger and the article was written on December 14, 2016. The article first talked about how glaciers are very dynamic, however they change their shape and volume at a very sluggish pace. Over the last century there are studies that shown that the glaciers are actually getting smaller in size and not reaching their farfest recorded boundaries ( where they attach to land ). One of the recent studies showed that with the glaciers getting smaller there is an 99 percent that climate is the reason. The scientists researched 37 glaciers from Europe, Scandinavia, Asia, North America, and the Southern …show more content…
I think one of those reasons was that I could understand what the article had to say because this information was not all new to me. When I went to Glacier National Park the Park Rangers were saying how the glaciers were getting smaller and how the glaciers may not there for the future generations to see. This was when I first heard and really understand the problem with the glaciers. Since I learn about the problem and I had some background information about the glaciers, I feel I had a better understanding of the article and could say whether I agree or disagree with what the article has to say. I would agree to the article because the article gave good reasons and the article showed what steps the scientist did to research. 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. The article answered my question some to how the glaciers can shrink so much that they are gone for future generations to

Scientists believe that the ice in Glacier bay during the first ice age could have been nearly 1000 feet thick! And as the original glacier has diminished in size from that time, it has left 20 separate glaciers, of which two are tidewater glaciers that calve into the bay. And as recently as 200 years ago, in almost all of Glacier Bay, a fjord was covered by the Grand Pacific Glacier; since then the ice has been retreating and Glacier Bay, now 65 miles long, has taken it’s present form. When Captain Lester A. Berdslee of the U.S. Navy was in it in 1980, its beauty took him away. He gave it the name “Glacier Bay” because of it’s striking locality. This was also the same year when it was declared an national park and preserve. Though years earlier it was proclaimed a national monument in 1925. And then in 1992 it was designed a UNESCO World Heritage site. Today, the park’s headquarters are at Gustavuas, near the mouth of the bay. The bay, which is studded with many largely treeless islands that are used a rookeries by thousands of seabirds, has fjord like inlets that terminate at ice cliffs or sheer faces of the glaciers. It contains at 16 active glaciers that descend from the St. Elias Mountains to the east and Fair-weather Rage to the west. The park and reserve cover an area of 5,129 square miles and includes Glacier Bay itself, the northern, southern, and western slopes of Mount Fairweather, and the U.S. portion of the Alsek

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...
Glacier melting has become very rapid in the European Alps since 1980, and 10 to 20% of the ice in the Alps was gone in less than two years. Half the amount of Europe's Alpine glaciers has vanished since 1850. Within the next hundred years, 50 % of those left, will as
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.
Currently, scientists believe that once an ice age has been triggered, oceanic circulation currents can change and the mixing of the oceans cools the southern hemisphere. As glaciers begin to accumulate in the northern hemisphere, solar heat is reflected off the snow which leads to further cooling.

Climate changes originating from changes in Earth's orbit and changes of its axial tilt are proposed causes of glaciations according to Esmark, in a paper published in 1824. There are three important types of affirmation for ice ages namely; chemical, geological, and paleontological.
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
