World history climates essay

Holocene From ancient times, people suspected that the climate of a region could change over the course of centuries. For example, Theophrastusa pupil of Aristotletold how the draining of marshes had made a particular locality more susceptible to freezing, and speculated that lands became warmer when the clearing of forests exposed them to sunlight.

Renaissance and later scholars saw that deforestation, irrigation, and grazing had altered the lands around the Mediterranean since ancient times; they thought it plausible that these human interventions had affected the local weather.

When farmers, called "sodbusters" took over the Great Plains they were told that "rain follows the plough. Some experts reported that deforestation not only caused rainwater to run World history climates essay rapidly in useless floods, but reduced rainfall itself. European professors, alert to any proof that their nations were wiser than others, claimed that the Orientals of the Ancient Near East had heedlessly converted their once lush lands into impoverished deserts.

When the figures were analyzed they showed many rises and dips, but no steady long-term change. By the end of the 19th century, scientific opinion had turned decisively against any belief in a human influence on climate. And whatever the regional effects, few imagined that humans could affect the climate of the planet as a whole.

By the late 18th century, geologists found evidence of a succession of geological ages with changes in climate. There were various competing theories about these changes, and James Huttonwhose ideas of cyclic change over huge periods of time were later dubbed uniformitarianismwas among those who found signs of past glacial activity in places too warm for World history climates essay in modern times.

As he hiked in the Val de Bagneshe noticed giant granite rocks that were scattered around the narrow valley. He knew that it would take an exceptional force to move such large rocks. He also noticed how glaciers left stripes on the land, and concluded that it was the ice that had carried the boulders down into the valleys.

You can learn about how civilizations have grown and interacted with one another from the time of B.C.E. to the present day%(21). Climates can be classified according to the average and the typical An oceanic climate is typically found along the west coasts at the middle latitudes of all the world's continents, and in Paleoclimatology is the study of past climate over a great period of the Earth's history. It uses evidence from ice sheets, tree rings, sediments.

Jean de Charpentier wrote, "I found his hypothesis so extraordinary and even so extravagant that I considered it as not worth examining or even considering. Venetz convinced Charpentier, who in turn convinced the influential scientist Louis Agassiz that the glacial theory had merit.

In Agassiz was the first to scientifically propose that the Earth had been subject to a past ice age. A field trip to the Alps with Agassiz in October convinced Buckland that features in Britain had been caused by glaciation, and both he and Lyell strongly supported the ice age theory which became widely accepted by the s.

The earth then absorbed visible light and emitted infrared radiation in response, but the atmosphere did not transmit infrared efficiently, which therefore increased surface temperatures.

He also suspected that human activities could influence climate, although he focused primarily on land use changes.

In an paper Fourier stated, "The establishment and progress of human societies, the action of natural forces, can notably change, and in vast regions, the state of the surface, the distribution of water and the great movements of the air.

Such effects are able to make to vary, in the course of many centuries, the average degree of heat; because the analytic expressions contain coefficients relating to the state of the surface and which greatly influence the temperature.

Her work was presented by Prof. Joseph Henry at the American Association for the Advancement of Science meeting in August and published as a brief note, but scientists failed to take notice. An atmosphere of that gas would give to our earth a high temperature; and if, as some suppose, at one period of its history, the air had mixed with it a larger proportion than at present, an increased temperature from its own action, as well as from increased weight, must have necessarily resulted.

He found that water vapor, hydrocarbons like methane CH4and carbon dioxide CO2 strongly block the radiation. But that was only one of many possible causes.

Another obvious possibility was solar variation.

Shifts in ocean currents also might explain many climate changes. For changes over millions of years, the raising and lowering of mountain ranges would change patterns of both winds and ocean currents.

Or perhaps the climate of a continent had not changed at all, but it had grown warmer or cooler because of polar wander the North Pole shifting to where the Equator had been or the like. There were dozens of theories. During some periods the Northern Hemisphere would get slightly less sunlight during the winter than it would get during other centuries.

Snow would accumulate, reflecting sunlight and leading to a self-sustaining ice age. InPeter Kropotkin wrote about his observations that since the Industrial Revolution, Siberian glaciers were melting.

Chamberlin By the late s, American scientist Samuel Pierpoint Langley had attempted to determine the surface temperature of the Moon by measuring infrared radiation leaving the Moon and reaching the Earth. This result was unsurprising given that scientists had known about infrared radiation absorption for decades.

He realized that the cooler atmosphere would hold less water vapor another greenhouse gas and calculated the additional cooling effect.

He also realized the cooling would increase snow and ice cover at high latitudes, making the planet reflect more sunlight and thus further cool down, as James Croll had hypothesized.

Overall Arrhenius calculated that cutting CO2 in half would suffice to produce an ice age.Vanessa Cotterill Writing Assignment #1 There are many ways that the world’s changing climates had influenced the settlements of Oceania and the Americas.
