The Cause And Effects Of The Little Ice Age

We all know that atmosphere is continually evolving. We have had ice ages and hotter periods when gators were found in Spitzbergen. Ice ages have happened in a hundred thousand year cycles for the last 700 thousand years. There also have been time periods that seemed to have been hotter than the present in spite of CO2 levels being lower than they are currently. Overall what I am saying is that we have had the medieval warm period and the little ice age. Because of these evolutions there has been different effects on the earth.

Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997). Indeed, glaciers present sensitive indicators of climate change and global warming and by estimating and monitoring the dynamic evolution of these ice masses, several

It was during the Pleistocene period when the most recent episodes of global cooling from the last Ice Age took place. During this time much of the World's temperate zones were alternately covered by glaciers during cool periods and then uncovered during the warmer interglacial periods when the glaciers retreated.[110]

In 1827 Louis Agassiz was the first to scientifically propose that the Earth had experienced a past ice age, which he said could explain previous observations that erratic blocks of alpine rocks scattered over the slopes and summits of the Alps, had been moved there by glaciers. He presented the theory that ancient glaciers had traveled throughout the entire northern hemisphere and deposited these rock formations along the way. Though many before him had theorized moving glaciers, he was the first to label this period of time as the Ice Age.

The passage declares numerus reasons in hope of justifying the real causes of Little Ice Age existence during 1350 till 1900 CE. On the contrary, the lecture challenges all the aforementioned theories by passage and believes inasmuch as the outdated information used by passage all those clarifications are merely sheer implausible misconceptions. In what follows, three major hypotheses and their critics will be delved into nut briefly.

Global warming is the warmth of Earth’s temperature by the sunlight as a main cause. 30 percent of the sunlight reflected back into space by clouds, and the remaining 70 percent is absorbed by land, air and ocean. Solar energy does not stay bound up on Earth’s environment perpetually. Global warming is a phenomenon, it has started from the last century. It impacts on Earth and that can lead to climate change in the world. A lot of scientists have approved that global warming is a fact and have approved natural changes and they discovered the reason behind that is global warming. “Understanding the cause of the Pleistocene ice ages has been a significant question in climate dynamics since they were discovered in the mid-nineteenth century. The identification of orbital frequencies in the marine record, a proxy for global ice volume, in the 1970s demonstrated that glacial cycle are ultimately paced by astronomical forcing” (Jeremy. D. 1). Therefore, we should save our planet by preventing global warming from happening.

In the essay, “Global Warming is Eroding Glacial Ice,” Andrew C. Revkin argues that global warming is the primary cause for many of the world’s natural disasters; including flash floods, climate change, and the melting of the polar ice caps. He includes multiple accounts of expert testimony as well as a multitude amount of facts and statistics to support his theory that global warming is a threat to the world. However, in the essay “Cold Comfort for ‘Global Warming’,” Phillip Stott makes the complete opposite argument. He argues that global warming is nothing to be worried about and the melting of the polar icecaps is caused by the interglacial period we are currently in. After reading both of these essays and doing

A glacier occurs when the climate of an area is so cold that new snow does not completely melt each summer and more snow is added in the winter. After many winters the accumulation of this snow becomes compact and re-crystallizes, thus forming a glacier. Currently, glaciers cover about ten percent of the Earth's surface. Yet, in the past, glaciers covered much more land and were thousands of meters thick. (Tierney)

The world warmed by about 0.7°C in the 20th century. Every year in this century has been warmer than all but one in the last century (1998). If carbon-dioxide levels were magically to stabilize where they are now (almost 390 parts per million, 40% more than before the industrial revolution) the world would probably warm by a further half a degree or so as the ocean, which is slow to change its temperature, caught up. But CO2 levels continue to rise. All this affect the ice pack in the Arctic. As temperature rises, ice melts. This causes many problems.

Europe had experienced a general cooling of the climate between years 1150 and 1460 and a very cold climate between 1560 and 1850. This event came to be known as the “Little Ice Age.” This cold weather had impact on agriculture, health, economics, emigration, and art and literature . The term “Little Ice Age” was named by Francois Matthes in 1939 to describe the most destructive climate drop in Europe. This ice age was consisted of mountain glaciers which brought temperatures as low as 2 degrees Fahrenheit. Numerous people got sick and some were even killed and starved to death because of a famine. Farms and villages were lost due to the cold weather. It is unknown on what caused this “Little Ice Age.” We do know that this event impacted

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.

Before humans and human inventions developed, climate changes were a result of natural causes. Climate changes since the Industrial revolution in the 1700s can be explained by natural causes. Today in 2016, it seems that the only explanation to sudden changes is our own human population. Our population has been burning fossil fuels such as coal, oil, natural gas, and other non-renewable items. These items have been found to be the main cause of global warming or climate change in our world today.

First, the passage talks about the causing may have been caused because of the oceans currents disruption. Although, the professor refutes this and mentions the disruption that have been happened only affected Europe and North America. Even though, there is no explanation why the little ice age has been reached the Newzeland, and Africa. Eventually, as far as no explanation for that so this is not the cause.

In the summer, the amount of sunshine received in the Northern Hemisphere can control the advance and retreat of ice sheets because of changes in Earth’s orbit. This has been the cause of ice ages in the past, when Earth has experienced long periods of cold temperatures (NRC, 2010).

One of the effects of global warming is the polar ice caps’ melting. Scientists have been researching and examining the polar ice caps for a long time and they have come to the conclusion that the thin ice sheets are slowly wasting away. They have also found out that Greenland’s glaciers are getting smaller and smaller. Places around the globe that use to be covered in ice and snow are now showing more green terrain as the years go on and as the winter months grow warmer. The polar ice caps are melting more and more due to higher global temperatures. This is really bad because the ice caps “reflect and help regulate the Earth’s temperatures.”
