The Little Ice Age And Its Impact On Society

Scientists have found that the Earth was formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. As gravity slowly gathered this gas and dust together into clumps, it became asteroids and small early planets called planetesimals. These objects collided repeatedly and gradually got bigger, building up the planets in the Solar System. Although scientists are very close to answering the question, they still continue to search for the exact answer to how the Earth was created. With all the evidence presented, it is hard to refute from scientific theories. This becomes cumbersome to many religions because in their eyes God has always been the creator of the Earth.

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

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.

Ice ages are well documented in Earth’s history, and they are proven to be relatively frequent. But what if that ice age persisted over not just regions near the poles, but around the equator as well? The term “snowball Earth” refers to a condition where Earth is completely covered by ice. Evidence indicates that snowball Earth may have been around in the Neoproterozoic. In fact, evidence points to the conclusion that these conditions happened three separate times in the Neoproterozoic. A snowball Earth condition is hard to prove, but this theory may explain several different phenomena. However, it is not accepted by all, there is evidence against a snowball Earth as well. Some believe that a snowball Earth would not have been possible in past climate conditions while there are views that defend the idea of more of a ‘slushball’ Earth rather than a planet entirely frozen on the surface.

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

The evolution of that formation created the world we live in today. The earth has been in existence for a little over four point five billion years to be exact. The earth shares a story that we are still exploring. From its colorful coral reefs in bright and vibrant

The over loaded carbon dioxide trapped in the atmosphere like a warm blanket held the heat from lease to the space. Climate change is a part of the Earth's history. There have been dramatic fluctuations in overall average temperature

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.

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

Over 35 years ago, climatologist Wally Broecker coined the term global warming in a paper outlining the trends that he was noticing with temperature and C02 levels (Stefan). Ever since then, the debate has heated up on the controversy of global warming. Politicians have even used the issue to boost their campaigns. Some question whether the earth’s temperature is rising at an unusual rate. Scientists perform experiments from glacial ice to observe the correlation between carbon dioxide levels and temperature. Scientists have changed the debate over the years from debating whether global warming was actually happening to the current debate about what is causing global warming. Therefore, the term global warming in this paper refers to

The statement regarding the Little Ice Age (LIA) and its relation to modern warming is incorrect at multiple points and contains poor logical reasoning in arriving at its conclusions.

Due to recent increases in the Earths average temperature Climate Change has become a highly discussed topic in society. This has caused individuals to solely focus on the increasing temperatures of today and completely neglect temperatures that the planet has experienced in the past. When looking at paleoclimate data one can clearly see the fluxuations in the ice age cycles (periods of cooling and warming). Ice age cycles are amplified by positive feedback systems that make the earth cooler or warmer depending upon the physical process that is being altered. In his response Bruce Parker, a physical oceanographer, discussed the impact that these positive feedback loops have on Earths overall temperature and how scientists have yet to figure out what causes the amplifying mechanisms to switch from warming to cooling.

“The Ice Age”. Hearing these three words, you might think about the delightful animated kids movies that our modern culture has come to love. You might think about how old the ice cubes are that you put in your freezer a while ago. But by the end of this section, in which you will learn about glacial forces, your appreciation for “The Ice Age” will surpass boundaries that you never dreamt were possible. While the average human being’s understanding of the ice age may remain limited, you may find yourself becoming what some may call “an expert” on how glacial forces shaped the Howe Sound - Whistler region.
