Refrigerants that Cause Ozone Layer Depletion written by:
Both CO2 and CH 4 vary between glacial and interglacial phases, and concentrations of these gases correlate strongly with temperature. However, various proxies and modeling suggests larger variations in past epochs; million years ago CO2 levels were likely 10 times higher than now.
No volcanic carbon dioxide emission of comparable scale has occurred since. In the modern era, emissions to the atmosphere from volcanoes are approximately 0. Major greenhouse gas trends. Since the beginning of the Industrial Revolutionthe concentrations of most of the greenhouse gases have increased.
Many observations are available online in a variety of Atmospheric Chemistry Observational Databases. Anthropogenic greenhouse gases[ edit ] See also: Climate change and ecosystems This graph shows changes in the annual greenhouse gas index AGGI between and Since about human activity has increased the concentration of carbon dioxide and other greenhouse gases.
As a result of this balance, the atmospheric mole fraction of carbon dioxide remained between and parts per million for the 10, years between the end of the last glacial maximum and the start of the industrial era.increasing use of chlorofluorocarbons which can break down and destroy ozone molecules into other elements.
Other pollutants such as halons, chlorine gas and Documents Similar To The Green House Effect.
Water Based Pain t For most home projects, this is your go-to paint. Also called latex paint, it has a binder that is dissolved in water. In general, water-based paints are less toxic and contain fewer volatile organic compounds (VOCs) than solvent-based (also called oil-based or alkyd) paints. The Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone rutadeltambor.com was agreed on 26 August , and entered into force on 26 August , followed by a first. Chlorofluorocarbons (CFCs) are to blame for global warming since the s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal.

. (ii) poor in dissolved oxygen. (iii) highly polluted. (iv) not suitable for aquatic life.
5. Which of the following statements is wrong? (i) Ozone is not responsible for green house effect.
Chlorofluorocarbons (CFCs) are fully halogenated paraffin hydrocarbons that contain only carbon are two factors that contribute to CFCs' "super" greenhouse effect. Another such factor is the low concentration of the compound.
Because CO 2 is close to saturation with high concentrations. Sep 08, · Ghg and carbon accounting effect of chlorofluorocarbons other trace gases. Gov monitoring references faq greenhouse gases. What is Green house effect and how is it associated with Global. Air conditioning and refrigeration systems require refrigerants to produce their cooling effect.
Chlorofluorocarbon refrigerants or CFC refrigerants are being used in many refrigeration since the last five or six decades and have been since found to cause ozone layer depletion, which damages the atmosphere's ability to protect the earth from the .
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. If a planet's atmosphere contains radiatively active gases (i.e., greenhouse gases) they will radiate energy in all directions.
