The Pros And Cons Of Glaciers

There is a lot of vegetation for them to make a good shelter. The shrubs would be good for making fires for next to your shelter. The people could dig a hole to use it a shelter year round. You could use it in the warmer, but still cold months to keep you out of the sun. With the little, but a lot of it, shrubs, they could make weapons like a spear or arrowhead to kill animals. And with the animals that they kill they could turn those into clothing year round. With it being cold all of the time there would be a lot of snow that they could use as water. You could do the same thing with the ice if you melted it. And one last positive is with the younger kids or the adults maby they could have snow fights.

The global mean surface temperature is projected to increase by around 0.3 to 4.8 degrees Celsius above the pre-industrial values by the end of the 21th century. Therefore, if we continue to not check the anthropogenic emissions, the increase may be around 8 to 10 degrees Celsius, which is incredibly damaging to various ecosystems internationally. It is difficult to determine the possible aftereffects of the ice sheets melting because the equilibrium-response timescales of them is longer than both the atmosphere and ocean. The ice-sheet/ice-shelf model shows that if the atmospheric warming increases 1.5 to 2 degrees Celsius above the present temperatures, the Antarctic ice shelves will collapse and trigger a centennial scale response –a never-ending

Collaborating on an international level remains important for conducting ice patch research due to the rapid melting of alpine ice and decay of valuable artifacts. The work conducted for this thesis included cooperation from Parks Canada. Ice patch research was conducted not only on the U.S. side of the international border, but also on the Canadian side of Chilkoot Pass. Parks Canada allowed me and KLGO archaeologists to use the Canadian warden cabin at the summit of Chilkoot Pass as a basecamp for the ice patch study (Figure 1.4). Working between two sovereign countries emphasizes the matter of climate change as a global issue and the importance in maintaining international relations. Maintaining international relations benefits the scientific community on a global scale and provides significant research opportunities.

Glacier National Park, located in Montana, is known for its impressive glaciers. Due to climate change, these glaciers have begun retreating at an alarming speed. The melting of glaciers impacts the whole ecosystem, biotic and abiotic factors alike. Signs of change can be seen in the rivers, meadows, and animals.

Mauri Pelto, a glaciologist, studied a glacier on Mount Baker, in Washington State. The glaciers are melting, as the planet becomes warmer. “At the rate it is losing mass, it won’t make it 50 years,” said Pelto. Glaciers from Mount Baker and the North Cascades are getting smaller. Over the past thirty years, seven glaciers have melted. An estimate was made that the 116 glaciers that they studied in Alaska have lost a total of 75 billion metric tons of ice. There were 150 glaciers in Glacier National Park in 1850. Now, there are only 25."They are losing volume at a faster rate than ever before," Pelto said. "If you cannot sustain a glacier at a place like this in the Lower 48 states, there is no hope."

In Greenland and in the Arctic I was astonished to see that ancient glaciers are rapidly disappearing well ahead of scientific predictions. All that I have seen and learned on this journey has terrified me. For decades, scientists have struggled to get the same basic message across: global

A glacier is a large body of ice that moves slowly across land and are formed by there being a higher snow gain rather than a snow melt. Glaciers move by a small amount of ice melting and the glacier sliding. Glaciers can help and destroy the landscape in front of them but they can also shape the land into something amazing. Glaciers were once present in Minnesota thousands of years ago and played a massive role on the landscape we live on today, and as they melted they left behind large amounts of water and formations.

Did you know that mountaintop removal coal provides around three percent of our countries electricity? That does not seem like much, especially considering all the damage it causes. Large areas of wildlife habitat have been destroyed so these mountaintop removal companies can gain and make a profit. These companies do not care about the people in the communities they are hurting. Companies also do not understand that animals can become exterminated from this, and they have been.

One of nature's most powerful and influential forces is also one of nature's coldest and slowest processes. These great icy rivers are called glaciers and have formed some of the most beautiful scenery on this planet. These enormous frozen bodies of water are often thousands of feet wide and deep and many miles long. They cover millions of acres of land and drastically change the land into beautiful mountains with many amazing features. One of the areas where glaciers have been most influential is in Yosemite National Park in California. Here almost every glacial feature is shown. However, before this information about glaciers in Yosemite was clear, there was the Yosemite Controversy with

One of the most controversial topics I know of is oil drilling in the Arctic National Wildlife Refuge. It seems whenever oil prices increase so do the debates on drilling for oil. Everyone feels the pressure, but what is the bottom line, who will suffer and who will gain. We should always consider short-term and long-term as well as the pros and cons. It always makes my blood boil, when there is a change in the oil prices and people jump to the conclusion we should start drilling for oil everywhere.

As we slowly approach the end of summer, and the beach days and neighborhood BBQ’s are slowly coming to an end, it is no surprise that looking into what family fun events this fall await us.

On August 25, 1916, President Woodrow Wilson signed the act creating the National Park Service to conserve natural land from being destroyed or messed with. This enabled it to be preserved for many generations to see rather than it be torn down and made into some lame houses or buildings.

Have you heard what is happening to the environment? Like how Greenland loses is 286 Gigatonnes of ice per year! And as of January 22, 2017, it has lost 3778.7 Gigatonnes since 2002! Why you ask? It’s due to Climate change. Climate change is a serious problem in our world, It can either end it or make it prosper that is why I chose to research it. Climate change won’t just effect on a country or continent, it will affect the whole world, and we are a part of that world. So, I decided to research it to see what we as humanity can do about climate change. To help I asked myself more questions such as “What will happen if we don’t intervene?”, “What is the source of the problem?”, “What are our choices as humanity?” After my research, I believe that there is a way to stop climate change and to do that we as humanity need to work together.

Along with the deep seas, there are signs of rising sea levels. This is being contributed to the melting of Glaciers. According to National Geographic’s “The famed snows of Kilimanjaro have melted more than 80 percent since 1912. Glaciers in the Garhwal Himalaya in India are retreating so fast that researchers believe that most central and eastern Himalayan glaciers could virtually disappear

Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world.
