Being born and raised in Juneau‚ Alaska I have sadly seen over a dozen glaciers recede at a rapid rate‚ each year being a record-breaking year. Years where snow fall has been minimal because the difference of a few degrees. Unfortunately‚ these unusual years are become the standard. The farther north you travel the larger the

Reading Assignment: Chronicles of Ice Summary: In Chronicles of Ice‚ Gretel Ehrlich sets out to “learn whatever lessons a glacier has to teach”‚ and to share what she has learned with us‚ as readers. The lesson the author relays to us is that the fate of the glacier is inextricably linked to that of the biological health of the Earth itself. Ehrlich uses the glacier as a device to show both cause and effect of the declining health of the Earth’s climate. The gases and particulate trapped in the ice

It is generally agreed with the direction of the drumlin long axis reflects local direction of ice movement with the stoss end usually pointing up-glacier. The ice moulded or streamlined form appears to be produced by variations in stress levels at the base of the ice‚ although the precise mode of formation of the features is far from clear.

Alaska’s glaciers. I found this essay to be touching and nostalgic. The author shows throughout the essay how his relationship has changed with Stickeen and how inspiring Stickeen was to him through their journey. Toward the end of the story the author and the dog are both changed. They are forever bonded at the end of their expedition. At the beginning of this essay what captured my attention was how the men were going to take such a small dog on the expedition to the Alaskan glaciers with them

the Earth‚ but not really wanting to poison the Earth. Gretel Ehrlich writes her essay‚ “Chronicles of Ice‚” a little differently. She uses personal experiences of visiting a glacier and the way that it is falling apart to explain climate change. She uses detailed‚ sensory description to explain what is happening to the glaciers that are so important to us. However‚ in Atul Gawande’s essay‚ “The Cancer Cluster Myth‚” he uses a different approach. He uses the physical health of the people in our nation

Paleoclimate is the climates of previous years of the earth’s history. The first way paleocimatologists study the earth’s past climates is by pollen. Pollen is sometimes trapped in lakes and bogs preserving it for many years. So when the scientist’s exstract the pollen they can see what type of plant it comes from. For example if they got the pollen from a silk tree they would know that that previous climate was a warmer one. Because silk trees need warm weather to grow. Then they count the number
