The Little Ice Age : A Period Of Cooling

It is a beautiful day outside. The sun is shining brightly down on the earth. The temperatures are warm, and you are outside enjoying the beauties of nature. Then suddenly the temperature begins to drop. It is now cold and brutal outside. You would probably be wondering what just happened to the weather. What could have caused this? With what Mr. Calvin has said in his story The Great Climate Flip Flop this may and will happen soon if we do not choose to act.

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.

There have been at least five major ice ages in the pass one billion years. The most recent was called the Pleistocene Ice Age, which began about two million years ago. Interglacial periods occurred where temperatures increased slightly and the glaciers would melt and retreat.

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

Roughly 2.4 million years ago, the Ice Age began on Earth. Over time, the thick snowpack that had accumulated in the Sierra Nevada due to cooled temperatures compacted into giant sheets of ice. These ice sheets became glaciers when they were set into motion due to the pressure of their own weight. The glaciers cleared everything that came in their path including boulders, soil, and trees; everything but the bedrock, which was instead smoothed out, was completely stripped. As global temperatures fluctuated over the years, the glaciers have advanced and retreated multiple

Throughout the Pleistocene ice ages, large areas of the earth were covered by vast ice sheets. Global sea levels dropped up to 120 metres below present-day coastlines, exposing large areas of land that were once flooded by shallow seas. These lands became colonised by vegetation, animals, birds and insects over time. During the Ice Age, the island continent to the south-east of Asia comprised New Guinea, Australia and Tasmania as a single land mass. Separating this continent from Asia was a narrow sea about one hundred kilometres wide, over which the first ocean crossings were made sometime before 60,000 years ago.

The true impact of “The Little Ice Age” began around 1600 and lasted until the 1800’s. During that time in Europe is when it was at its height. It was considered to be the most significant climate event of the last millennium. Only until recently have climatologist discovered research of climate conditions in historical times. As stated before, no one is quite sure how “The Little Ice Age” evolved. Climatologist and historians have had many discussions on what they think was the main cause of the ice age. Today they are able to determine the yearly average temperatures, rainfalls, volcanic activity, and the effect of the sun during that period . What we know is that the sun experienced a “quiet” period, meaning its intensity was not that strong. Therefore, a cooling occurred. Sunspots which determine the suns strength were noted to be in decline. Volcanic activity is to be another known source of the cause. As the volcanoes erupted they shot out particles and gases into the air. With these gases floating in the

Every family needs time together before children grow up and are off being involved in the world. Ice Age 4: Continental Drift is the fourth movie in the Ice Age movie series and in my opinion is the funniest for families with small children. This movie is perfect for nights with nothing going on. This comedy has voices of Ray Romano, Queen Latifah, and Keke Palmer as the main characters along with the hilarious voices of many other actors and actresses. Ice Age 4: Continental Drift is a comedy for the whole family, full of action, suspense, and will keep you entertained until the end.

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.

     Sunspots, where most solar flares occur, are dark patches on the surface of the sun. This is where the gas of the sun is not so hot and causes it to take on a different color. A typical sunspot is about 22,000 miles in diameter and the number visible sunspots from satellites are about 5 to 100, it varies.
