Greenhouse gases Carbon dioxide is a colourless‚ odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials‚ by animals when they respire‚ and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all‚ we exhale it with every breath and use it to make our drinks fizzy. However‚ carbon dioxide is considered a pollutant because‚ as a greenhouse (heat-trapping) gas‚ it’s a significant contributor to global warming. In the last 150

Greenhouses allow for greater control over the growing environment of plants. Depending upon the technical specification of a greenhouse‚ key factors which may be controlled include temperature‚ levels of light and shade‚ irrigation‚ fertilizer application‚ and atmospheric humidity. Greenhouses may be used to overcome shortcomings in the growing qualities of a piece of land‚ such as a short growing season or poor light levels‚ and they can thereby improve food production in marginal environments

absorbs more energy than it emits back into space. Thus‚ energy absorbed by the surface and re-radiated back into space is captured by the atmosphere and remains there. This is known as the Greenhouse Effect‚ and there are other feedbacks that occur that exacerbate

What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and

opposing perspectives on climate change. Greenhouse Effect Because of the transparency of the atmospheric gasses to visible light‚ sunlight is able to largely penetrate the earth’s atmosphere and reach the ground‚ where it is absorbed heated up‚ and then re-emitted in the arrangement of infrared radiation. In this

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‚

Greenhouse effects and global warming are an uprising environmental issue. The greenhouse effect is the process by which absorption and emission of infrared radiation by gases are released in the atmosphere. The major greenhouse gases are water vapor (36 -70%)‚ carbon dioxide CO2 (9-26%)‚ methane CH4 (4-9%)‚ and ozone O3 (3-7%). Since the industrial revolution‚ human activity has increased the amount of greenhouse gases‚ leading to increased levels of CO2‚ methane and troposphere ozone. Fossil fuels

Introduction – This paper contains a general overview of the greenhouse effect and a deep understanding about the global warming phenomena. It includes general background knowledge about greenhouse as well as how does human action contribute and influence its effect. This paper also highlights on the nature and fundamental causes of greenhouse gases. The term of Greenhouse: A greenhouse which is also known as a glasshouse is an architectural building with roof and walls made from glass or

Greenhouse gases are the cause of global climate change. The main greenhouse gasses are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and chlorofluorocarbons. Although most of these gases are natural‚ they are all being put into the air at a much more dangerous rate than normal. Water vapor‚ the greatest natural contributor to global warming‚ and lasts about nine days in the atmosphere. Water vapor is in the atmosphere more recently‚ because there has been more water that has evaporated because

recognizing and understanding about the Greenhouse Effect revolves around the issue of climate change and global warming. It is essential to research and distinguish between the Enhanced Greenhouse Effect and Greenhouse Effect. It is also important to gather and collect from all aspects of the topic that requires fathoming the importance‚ effective things that could be done to improve the composition of the atmosphere and the impact of Enhanced Greenhouse Effect.
