Glacier

the world, such as the Vanuatu (M 7.1 on 10/21/2015), and the Chile earthquake (M7.8 on 9/16/2015). Within the year, my research interest changed to glaciology, based on a glaciology lecture in my geophysics course. Accordingly, I began researching glaciers in Antarctica with Sridhar…

Australia was originally in the Antarctic circle as part of Gondwana, a supercontinent that consisted of Australia, Antarctica, Africa, and South America. It was part of the land and then broke off and slowly moved up to where it is now. New Zealand and the other surrounding islands also came from this same land, but, they broke off to form islands of their own. Because of the greenhouse conditions on the planet at the time of Gondwana, the area, despite being in the Antarctic circle, had no…

Have you ever seen a polar bear? Not many people have. The population now is around 20 to 25 thousand. In the 70’s the population hit the all-time low, the ice they live on is melting due to global warming. The population will continue to drop so long as we don’t do anything about it, and soon, no one will get to see the snow white bear. In 2012, about 1.32 million square miles, which is right around 24%, of the Arctic Ocean was froze over. That is low considering that it dropped about 3% since…

(Gain attention) President Barack Obama once said “There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate.” (Reveal Topic) This statement by President Obama on climate change conveys how important the fight against climate change is. (Establish Credibility) I became interested in this topic after getting into a disagreement regarding climate change with my grandfather and how he doesn’t “buy into that…

Place In Barry Lopez’s “Losing Sense of Place” he talks about how Americans basically take our landmarks and geological features for granted. Lopez says, “In 40,000 years of human history, it has only been in the last few hundred years or so that a people could afford to ignore their local geographies as completely as we do and still survive.” This is very true over time the ideal of place is less meaningful; when America was discovered explores could not wait to map it out and now no one even…

more of bottled water is really just tap water in a bottle—sometimes further treated, sometimes not” (Natural, 2014). Bottled water can also have false advertisement; it was alleged that in one case: “A brand of bottled water, advertised as “pure, glacier water,” was found to be taken from a municipal water supply while another brand, flaunted as “spring water,” was pumped from a water source next to a hazardous waste dumping site. While “purified tap water” is arguably safer and purer than…

scientist know that it is an earth cycle is because it is actually getting colder. Scientist have found that the ocean is getting colder. “...rates of change in ocean heat content are ‘preponderantly negative’” (Hiserodt 13). Evidence of ice and glaciers have also been found. Scientist at Boulder, Colo say that the arctic ice is making a comeback and might even get larger over the next few decades (International). Ice being expanding is a sign that global warming could be a hoax after all. …

located in the Sierra Nevada mountain region is that most of the tourists have gone home. The crowds have dispersed enough by late fall that visitors can get a glimpse of beloved and timeless Yosemite points of interest including Bridalveil Fall, Glacier Point, Half Dome and Mariposa…

covered about ten woolly mammoths, and 300 American mastodon bones. Chris Widga, paleontologist at the Illinois State Museum, supposes mammoths can’t have been very common in Michigan, because there would have been a lot of waxing and waning of glaciers at the time the beasts walked the land. Michigan was under ice at the time of the mammoth, and by the time the ice had melted, mastodons outnumbered the mammoth, which makes this specific find a very rare one. New Mammoth Finds Are Always…

Never have humans had such abundance of information, easily accessible at the touch of a finger. Philosophers, doctors and scientists throughout history have labored their entire lives to study the science of earth, space and life on our planet. Now, with the amazing technological advances we’ve experienced in the last several decades, so many monumental discoveries have shed light on these fields, answering many questions and creating many more. The question now facing many of us in our quest…
