Introduction
Climate change has been constant for centuries, ever since the beginning of earth. Over thousands of years the earth has been shaped and re-shaped, due to weather and changing climates. A major factor that causes climate change is rain fall, related to cyclone and anti cyclone patterns in the area. Research into climate change will provide information to predict the change that a certain area may undergo, allowing for humans to adapt accordingly, agriculture and architecture can benefit from this; improving farming methods and crop selection also helping in the sustainability of buildings allowing for the dependence on heating or cooling to be taken into account. The following project is an investigation into how climate change …show more content…

Over the past 104 years, all the recordings and journals have been compiled into a spreadsheet by the current family members still residing on the farm. This data was collected to help the farmer determine what the previous rainfall was and how it was affecting his crops. The data complied will be used to extract a conclusion to this investigation. The data is arranged into a excel spread sheet, and will be analyzed accordingly by creating graphs and tables with relevant rainfall data and comparing the data to the available aerial photographs.
The data used for the following investigation does not include the years 1916 – 1917 (no data recorded) and 1920 during which only 5 months’ data were recorded. It is said that the person who recorded the data was a WW1 soldier during those years. There are a few years during which no values are available for certain months. However, these are much less than for 1920 and are consequently included in the calculations. All the data used is recorded in the appendix.
Data Analysis
The maximum and minimum monthly rainfall and year recorded are shown in the table below. During April, June, July, August and September no rainfall was recorded for a varying number of years. The total numbers of these occurrences are shown in the figure below.

This could be due to several reasons; during both years 1271.6mm and 1051 mm of rain fell respectively.

Figure 2: Aerial photograph taken of Trafalgar, year 1937.

Figure 3: Aerial photograph taken of Trafalgar, year 1948.
When comparing the two photographs taken 9 years apart, it is apparent that there is more vegetation and a greater density of vegetation in 1937. This could be due to a number of factors such as: Decrease in rainfall average over 9 years. Increase in human population over 9 years, greater population will result in vegetation destruction to make way for buildings and residency.
1950 to 1997
During this phase annual rainfall fluctuated considerably around the long term average. It was also during this phase that the absolute maximum annual rainfall (1791.1 mm) was recorded during 1978. As a simplification one could term this phase the “unsettled

Freshwater is also looked at as floodplain management is observed. The patterns of environmental quality are also examined. My hypothesis is that pH levels and drainage account for the significant differences in vegetation between the areas. This is because both drainage and pH levels play a role in what type of soil is available. The pH level determines the types of plants that grow and the drainage effects the type of soil present, which influences the

In the years following World War I the increase in farmland only continued, but while farming stayed on an upward trend the average amount of rainfall per year was on a downward trend. As they reached the depression in the mid 1930’s the Great Plains states were in a drought falling from an average of 33.4 inches of rain a year to as low as 9.7 inches, while anything lower than 20 inches being considered catastrophic (Document E). This drought on its own would not have been problematic if not for the ever increasing amounts of topsoil that was left vulnerable by the farming methods of the time. All the loose topsoil due to farming methods hit by a nearly decade long drought and hard winds completely lifted the topsoil off of the ground and blew it away. Topsoil that originated in Texas was blown as far away as New

The drought’s direct effect is most often remembered as agricultural, many crops were damaged by deficient rainfall, high temperatures, and high winds, as well as insect infestations and dust storms that accompanied these conditions. This caused many migrant workers to not be feed, as the food source was very limited. In conclusion these three events play a huge role in

The Dust Bowl, also known as the Dirty Thirties, lasted for about a decade and was a period in time in which dirt clouds billowed over the Great Plains that afflicted over 75% of the country (Riney-Kehrberg 32). The Dust Bowl affected a section of the Great Plains that extended over to Colorado, Kansas, Texas, Oklahoma and Northeastern New Mexico. The Dust Bowl was both a manmade and natural disaster that received its name from the "bowl-shaped" area it covered. In the 1930 's the United States suffered severe dust storms as high winds and asphyxiated dust swept the region until the early 1930 's. The Dust Bowl was the inevitable result of people intentionally exploiting the grasslands to its fullest extent (Richardson).

The flooding also brought up thick loess on either side of the river. The glacial floods created most of the familiar land forms that have come to define this river, the "dry" falls, mystifying basalt formations, giant ripple marks and unusual gravel bars. Also seen are shoreline and glacial features and processes in my vicinity. The climate in Riverside State Park has an Average Annual Precipitation of 17.62 inches.

DeekshithKumar Thadishetti Professor mankerian LS 690 July 31 2015 Climate change is one of the global issue that requires multiperspective approach. One of the key cause of climate change is air pollution. Air pollution occurs as a result of release of greenhouse gases to the atmosphere. There are two key sources of air pollution that should be targeted if the air pollution is to be reduced. The first source is the industrial stationay sources, which include electric power facilities.

The Dust Bowl of the 1930 's caused devastation for the mid-west at the time. It went on in Oklahoma,Texas,New Mexico, Colorado, and Kansas; however, slimmer areas were actually affected by the Dust Bowl like the Oklahoma panhandle, the Texas panhandle, the Northeast of New Mexico, the Southeast of Colorado, and the western third of Kansas. The drought that caused the Dust Bowl affected about 27 states and covered about 75% of the country. It was in April of 1934 that Black Sunday, the worst storm of the Dust Bowl, occurred. Shortly after President Franklin D. Roosevelt passed the Conservation Act.

In the 1930’s, many dust storms formed in the Great Plains. These storms traveled all across america, destroying lives by way of dust pneumonia, destruction of homes, and death in the process. Because of these very poor living conditions, one third of the affected population was forced to leave. The ones crazy enough to stay, we’re forced to endure through many days of suffering. But what is responsible for the terrible events of the 1930?

As most of the time Haitian coffee exports very stable, the impact of hurricane caused by climate change do influenced economic very much. There is one more example to show the impact of climate change (drought) to economic. The crop cycle, agriculture labor, and many other activities center around the wet and dry seasons, normally April to October, and November and March. However, because of the mountains, prevailing winds, and other factors, the amount of annual rainfall can vary considerably within Haiti: The Central Plateau and other windward regions receive 56 inches (1,400

Climate change is an irreversible consequence of the damage we do to our Earth. If we do not change our ways, the global temperature will swell, causing an unchangeable series of events, consecrating detriments onto all the existence upon Earth. In only about 140 years, the average global temperature has increased 0.8 degrees celsius, and the ramification is the irreparable destruction of the place where we and millions of other species live. The most important consequence of climate change is the global increase in temperature and how that is affecting various animal species all over the Earth, the health of humans, and the rapid rise of sea level.
