Answer questions for Earth the Biography: Ice
Please answer the following questions 1. According to Dr. Stewart, are we currently in an ice age? 2. How many times has the ice advanced in the last billion years? 3. Why is the face of El Capitan so smooth? 4. How does the ice affect the climate of an area, even the world?

ASSIGNMENT 2
——————————————————————
For this week find a glacier (use the USGS page, or other resources) and talk about how it has been affected (if at all) by recent climate change. Why did you pick this particular glacier? Where is it? How has it been changing? How long has it been studied? What evidence is there for the changes that are occurring? Is there an estimate on how much ice is being lost per year? What impacts are anticipated?What is the source of your information? Try to use glacier vocabulary: surging, calving, melt-water lakes, snow accumulation…
Also post a response to another person’s glacier description. Do you agree with their evidence? Are there any similarities or differences between your glacier and theirs? Do you have any questions about their glacier?
Instructor’s post:
I had the privilege of visiting a glacier in Iceland on my birthday in February 2017. There were really cheap flights to Iceland so my husband surprised me with a long weekend to Iceland, which is a geologist’s paradise! On my actual birthday we joined a class, put on crampons (those spiky things that keep you from slipping on the ice), learned how to use an ice axe, and then went for a hike on the glacier. We skirted around crevasses (deep cracks in the ice) and stood on the edge of a moulin (a deep hole where glacier melt-water drains down into the glacier). I even drank directly from a stream flowing on the surface of the glacier! And this was February, but it was the warmest they had ever had on record (which was fortunate since we Californians are not used to severely cold weather). The most amazing thing about the glacier, was the color of the ice, which was a deep teal blue. As snow compresses into glacial ice, the air bubbles which make snow white, are squeezed out and the ice becomes even more blue. The black material I am standing on in the photo is glacial flour (pulverized rock, in this case ground up basaltic lava). It is left on the surface as the ice melts rapidly our from underneath it.
The Eyjafjallajokull Glacier has been melting at an accelerated rate in recent years, along with all of the other glaciers in Iceland. It has been estimated that 11 billion tons of glacial ice are melting per year. One result is that the island is rebounding (rising) as the weight of the ice is lost, by about 3.5 cm per year. According to a study published in Geophysical Research Letters, there is also a connection between the island rising and increased volcanic activity. In 2010 the volcano underneath Eyjafjallajokull Glacier erupted, shutting down airports across England and parts of Europe. Could more eruptions occur in the near future?
