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

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 On the contrary, the lecture challenges all the aforementioned theories by passage and believes inasmuch as the outdated information used by passage all those clarifications are merely sheer implausible misconceptions.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

Beginning with Mark Hendrickson’s argument, he recognizes that the climate is changing. He wrote in his article “Climate Change-Hoax or Crime of the Century” that the Earth has emerged from a Little Ice Age not that long ago, and it would be worrisome if the climate around the globe was not warming

I have read three articles titled, “Digging out a lost city’s secrets”, “Skeleton dating back to the ice age sheds light on Native American origins”, and “Traditional turns into trendy in Guatemala’s finest clothing shops”. “Digging out a lost city’s secrets” is about a group of mexican scientists that discovered three chambers at the end of a tunnel beneath the “ancient mountain city of Teotihuacan.” “Skeleton dating back to the ice age sheds light on Native American origins” is about the skeleton of a teenage girl found by divers, underwater along with some extinct animal skeletons. “Traditional turns into trendy in Guatemala’s finest clothing shops” is about various types of clothing traditionally worn in Guatemala gaining popularity worldwide. I recommend reading “Skeleton dating back to the ice age sheds light on

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.

Media propaganda is abound with the announcements of a “Mini Ice Age” in our mist. We are constantly inundated with Hollywood movies depicting global destruction with an onslaught of rapid global climate changes. Is all this news media accurate and depicting true and accurate events covering our planet and solar activity? As a reader begins to look deep into the rhetoric, they will notice that there is very little – if any – scientific data to support the coming of a “Mini Ice Age” (Mann) as indicated by the multiple media corporations. As many scientists have pointed out, we are experiencing global climate change – they just have not confirmed that is a “Mini Ice Age.”

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.

11,700 years ago the geological epoch the Holocene was thought to of began following the Pleistocene epoch, together these time periods make up the Quaternary period. The Holocene has been described as being relatively warm and with a fairly stable climate. Not only this, but it is thought to coincide with the start of agriculture as human populations rose throughout the Holocene technology became more sophisticated aiding the rise of agriculture (Holden, 2012). The early anthropogenic hypothesis was published in 2003 by Professor W.F. Ruddiman, this was a three part hypothesis in which Ruddiman proposed humans reversed natural decreases in CO2 values within the atmosphere by deforestation. That they reversed natural methane decreases after 5,000 years by irrigating rice, they also caused a warming sufficient to prevent a new glaciation within the last several thousand years and during the Holocene (Ruddiman 2005). This hypothesis has attracted a lot of attention with many people both supporting it and criticising it. Throughout this essay I will be exploring the many arguments for and against the early anthropogenic hypothesis and stating whether or not human kind could have prevented the start of an ice age during the Holocene.

The case for attributing the recent global warming to human activities rests on the following undisputed scientific facts:

“When taking the heating of the entire climate system into account, our planet has warmed at a rate equivalent to 4 Hiroshima atomic bomb detonations per second over the past 15 years” (Cook). Our planet is becoming warmer. When scientists add up all the heat warming the land, oceans, atmosphere, ice melting, earth is accumulating heat equivalent to four Hiroshima bombs worth of heat per second. Global warming is a serious issue faced by our world as there has been a significant increase in temperature over the years. But the article published by Dr. Mark Sircus on “Global Warming -largest science scandal in the history” refutes the theory of global warming. Dr. Sircus states that there is no linkage between carbon dioxide and temperature leading to global warming, the sea level is not rising, arctic sea ice extent is now higher and climate change is due to solar activity. Dr. Sircus also points out that that the recent weather changes are not in line with global warming and “we are in the beginning of a deep freeze” (Global Warming - Largest Science Scandal in US History). NASA and the scientific community states that global warming is not a hoax and there is a rapid increase in Earth’s average surface temperature due to greenhouse gases released as people burn fossils. NASA states that the “key indicators of global warming are based on surface, satellite, and ocean temperature measurements, satellite measurements of energy imbalance and of receding glaciers, sea ice, and
