Greenhouse gas Greenhouse effect schematic showing energy flows between space‚ the atmosphere‚ and Earth’s surface. Energy exchanges are expressed in watts per square meter (W/m2). A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth’s atmosphere are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚

First of all‚ what is sulfur hexafluoride (SF6)? SF6 is a non-toxic‚ nonflammable and noncorrosive gas. SF6 has almost the same chemical properties of a noble gas and it does not react with other materials. Under standard conditions‚ SF6 is colorless and odorless gas in high electrical components. Furthermore‚ SF6 also inhibits surface erosion and oxidation. It has high partial vapor pressure at both normal and low temperatures. SF6 also has an excellent heat transfer. Its high molecular weight and

Explain how globalization has strengthened the failure of environmental policies to keep us with the problem of global warming and has strengthen industries in developing nations Globalization has been defined as the process in which societies‚ cultures‚ national and regional economies have combined through global trade‚ communication and transportation. The recent term for globalization focuses on more broader activities such as media‚ culture‚ technology‚ political and environmental factors

is happening and there are numerous facts to support its occurrence. Global warming is “the increase in Earth’s average surface temperature due to rising levels of greenhouse gases” (Conway). According the United States Environmental Protection Agency‚ “Gases that trap heat in the atmosphere are called greenhouse gases.” Greenhouse gases are broken down into four categories: carbon dioxide‚ methane‚ nitrous oxide‚ and fluorinated gases. Each category will be later looked at in further depth along

Defining climate change For most people‚ the expression “climate change” means the alteration of the world’s climate that we humans are causing‚ through fossil fuel burning‚ clearing forests and other practices that increase the concentration of greenhouse gases (GHG)1 in the atmosphere. This is in line with the official definition by the United Nations Framework Convention on Climate Change (UNFCCC) that climate change is the change that can be attributed “directly or indirectly to human activity

policies; they all are the signs of a developed country. All these significant words are subjected to one single term called stable climate condition. The science is fairly definite that climate conditions have been changing very rapidly due to rise in carbon pollution‚ greenhouse gas emission‚ and unlimited use of natural resources. One of the most significant challenges facing humankind and planet earth is to manage the environment in a sustainable manner. People start blame governments and corporations’ negligence which causes harm to the environment

warming and can it be prevented We have to face the fact that global warming is now a part of the planet‚ and may be due to the actions of humans making it human-caused. One of the causes of global warming is greenhouse-gas effect. It will continue for centuries even if and when greenhouse-gas emissions are stabilized in the future. Humans are helping to cause global warming by "Fossil fuel use‚ agriculture‚ and land-use change are fundamentally affecting the systems on our planet‚" (Science News

Factors that can shape climate are called climate forcings or "forcing mechanisms".[5] These include processes such as variations in solar radiation‚ variations in the Earth’s orbit‚mountain-building and continental drift and changes in greenhouse gas concentrations.
