The increasing demand to make human lives easier has pushed man to create chemicals which can help create products, heat and cool enclosed environment, and innovate technology. Unfortunately, such chemicals bring environmental consequences such as increased atmospheric temperature which lead to unfavorable weather changes, disruption of habitats of living things, and global warming.
As such, the U.S. and international governments are establishing regulations to limit the usage of manmade chemical substances that deplete the ozone layer, have a high global warming potential, or increase the fugitive emissions related to Greenhouse Gases (GHGs).
Refrigerant gas used to run commercial refrigeration units, as well as air-conditioning systems and heating, ventilation and air conditioning systems, is a chief cause of climate change because it is made up of hydrochlorofluorocarbons and chlorofluorocarbons. These gases contribute to global warming and also deteriorate the ozone layer. Because of the great harm refrigerant gas can cause to the Earth, the United States and many international countries are phasing out its usage, with complete removal by 2015.
Fossil fuels are a major cause of climate change because they lead to an increase in greenhouse gases in the atmosphere. Natural gas, oil and coal used to operate vehicles and generate electricity emit high levels of carbon dioxide, identified as a chief contributor to global warming. Fossil fuels also produce carbon monoxide, methane emissions, nitrous oxide and nitrogen oxides, all substances that impact air quality and global warming.
Scientists have found that methane is a significant cause of climate change. This greenhouse gas is discharged by cows, pigs, horses, sheep and other domesticated animals. Methane gas is also discharged from garbage in landfills, fertilizers, oil drilling and coal mining. In addition, when a gas leak occurs, a high volume of the dangerous chemical is discharged at one time.
Climate change is largely caused by the destruction of the ozone layer. It occurs from things we use every day. Commercial refrigerators, freezers, air conditioners, and heating, ventilation and air conditioning systems all contain harmful gases that continue to destroy the ozone layer. Damaging gases used in the operation of refrigeration and cooling equipment include hydrochlorofluorocarbons, chlorofluorocarbons, fluorine, chlorine, bromine, hydroxyl, nitric oxide and atomic chlorine.
There are several factors that are considered a cause of climate change. Such include animal agriculture, land use, deforestation, cement manufacturing and aerosols. To pinpoint measures which can help minimize impacts on global warming, such areas are being studied.
Many types of pollutants are a cause of climate change. Common pollutants are carbon dioxide, methane, black carbon and nitrous oxide. As these chemical pollutants increase, the ozone layer gets depleted, which results to global warming. Scientists warn that global warming can destroy the planet if no action is taken.
Simply put, too much heat stored in the atmosphere is the cause of climate change. The amount of greenhouse gases in the air contributes to atmospheric heat. Overwhelming heat can create significant changes in the Earth's climate, affecting both land and ocean. As a result, human, animal, plant and marine life will be severely impacted.
