How Human Activity Pollutes Climate Environmental Sciences Essay

Role of human activity on climate change is very important, because we live in this Earth and all things that we are making are affecting on all of us. Nowadays it is commonly discussed question for scientist and meteorologists how to avoid global warming, how to reduce acid rains and a toxic waste which is related to human activity on climate change. Human activity on climate change is affecting in a bad way, it changes weather and climate. We are facing it everywhere and everyday, because manufactures, toxic waste, greenhouse gases, cars and airplanes all of them affects on climate in different ways. Therefore, this essay will explain climate in general, how greenhouse gases affect on climate change, what greenhouse gases is and how human activity pollutes climate.

Climate is the average weather, which includes temperature, humidity, atmospheric pressure, wind and rainfall. It can be changed in different place in a different ways, in some places it might change very rapidly from day to day or from year to year. The climate of a location can be affected by terrain, altitude, ice or snow cover and water bodies which are nearby. Climate and weather is linked with each other, but the difference between climate and weather is usefully summarized by the popular phrase "Climate is what you expect, weather is what you get." (National Weather Service Office Tucson, Arizona. Main page, Retrieved on 2007-06-01). There are some instruments for measurement weather such as thermometers, barometers, and anemometers. The instruments used to study weather conditions over the modern time scale, their known error, their immediate environment, and their exposure have changed over the years, which must be considered when studying the climate of centuries past (Spencer Weart. The Modern Temperature Trend. Retrieved on 2007-06-01)

Greenhouse gases, it is gases which accumulate in the atmosphere, by causing concentrations to increase with time. Greenhouse gases include different types of gases such as, carbon dioxide, methane, nitrous oxide, ozone, water vapor and the halocarbons. The atmospheric amounts of gases are increasing, especially carbon dioxide, which has increased on 30% over the last 200 years (English for academic study “Reading and Writing” source book; Authors, John Slaght). Carbon dioxide gases has increased because of huge amount of fossil fuel use in transportation, heating and cooling buildings and the manufacture of cement and other goods. Water vapor is the gas phase of water, it can be produced from evaporation, melting of ice or boiling of liquid water. Water vapor is a greenhouse gas along with carbon dioxide and methane. Methane is a natural gas, it has no color, and this gas is flammable. Methane is high relatively potent greenhouse gas with a high global warming potential. Nitrous oxide is colorless and non-flammable gas, and it is also major greenhouse gas and air pollutant. Ozone is a blue gas, it is dangerous to warm up this gas because it can detonate. Ozone has ground level and the upper layer. Ground level ozone is an air pollutant with harmful effects on the respiratory systems of animals. The ozone layer in the upper atmosphere filters potentially damaging ultraviolet light from reaching the Earth's surface. It is present in low concentrations throughout the Earth's atmosphere. It has many industrial and consumer applications.( Rubin, Mordecai B. (2001). (PDF). Bull. Hist. Chem. 26 . Retrieved 2008-02-28.) It might increase global warming which will cause global problems for whole Earth and for everyone. The temperature has increased form middle of 20th century and it increased because of greenhouse gases resulting from human activity such as fossil fuel (IPCC (2007-05-04) "Summary for Policymakers"). If the temperature will keep increasing it will cause problems such as ice melting, which will increase amount of water in oceans and it will be non reversible global problem.

Consequently, pollution plays very important role in climate change which is also related with human activities. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited, but with the development of civilization man’s interference in nature began to increase large cities with thousands of smoky industrial enterprises appear all over the world. The products of their activity pollute the air we breathe, the water we drink, the land we grow grain and vegetables on. As we all know nowadays the amount of manufactures are increasing, so it means that pollution increasing also. Manufacture factories throwing huge amount of toxic waste in oceans, rivers and seas which is affecting not only at the climate change but also on the animals, trees and plants which is around with these toxic waste. Pollution of the toxic wastes affects on climate change by evaporation, when vapor goes to the atmosphere they form clouds which is returning back as acid rains. As a result, the pollution of air and the world’s ocean are causes of climate change.

As a conclusion, we are using cars, airplanes, we are producing goods by using machines which pollute climate. Human activity plays important role on climate change because we are using nature and not taking care of it and while we are doing such things it affects on us and our Earth. If we will continue causing damage on climate change without taking care of it we will increase damage that human activity does on climate change.
