Green House Effect biography, Green House Effect discography
Greenhouses are used to grow plants, especially in the winter.Greenhouses work by trapping heat from the sun.Besides the heating of an automobile by sunlight through the windshield and the namesake example of heating the greenhouse by sunlight passing through sealed, transparent windows,
the greenhouse effect has been
widely used to describe the
trapping of excess heat by the
rising concentration of
carbon dioxide in the
atmosphere.The carbon dioxide
strongly absorbs infrared and does
not allow as much of it to escape
into space.Greenhouse Effect Example
Bright sunlight will effectively warm your car on a cold, clear day by the greenhouse effect.Short wavelengths of visible light are readily transmitted through the transparent windshield.Shorter wavelengths of ultraviolet light are largely blocked by glass since they have greater quantum energies which have absorption mechanisms in the glass.Even though you may be uncomfortably warm with bright sunlight streaming through, you will not be sunburned.Increase in Greenhouse Gases
The increase in the concentration of carbon dioxide, one of the three major atmospheric contributers to the greenhouse effect has been carefully documented at the Mauna Loa Observatory in Hawaii.The 1990 rate of increase was about 0.The interesting cyclic variations represent the reduction in carbon dioxide by photosynthesis during the growing season in the northern hemisphere.Measurements of air bubbles trapped in the Greenland ice sheet indicate concentrations of 270 ppm in preindustrial times.These are sketches of the graphs produced in the IPCC 2007 report of the increase in key greenhouse gases.Contributers to Greenhouse Effect
Those gas molecules in the Earth's atmosphere with three or more atoms are called "greenhouse gases" because they can capture outgoing infrared energy from the Earth, thereby warming the planet.The greenhouse gases include water vapor with three atoms (H2O), ozone (O3), carbon dioxide (CO2), and methane (CH4).CFC's) can have a disproportionately large effect.To attempt to quantify the effects of greenhouse gases on the global temperature, climatologists use the "radiative forcing" of the current atmospheric content of these gases.Global Warming
An issue of major concern is the possible effect of the burning of fossil fuels and other contributers to the increase of carbon dioxide in the atmosphere.The action of carbon dioxide and other greenhouse gases in trapping infrared radiation is called the greenhouse effect.It may measurably increase the overall average temperature of the Earth, which could have disastrous consequences.Sometimes the effects of the greenhouse effect are stated in terms of the albedo of the Earth, the overall average reflection coefficient.The key reference used was Brohan, et al.Another depiction of the mean temperatures in the northern hemisphere was drawn from NOAA.Essentially any kind of tabulation you access will tell the same story.The temperature has gradually risen over the last 150 years.The large potential impact combined with the ambiguities of the science has given rise to many passionate extremes.Stephen Schneider of Stanford seems to me to be one of the more balanced voices.His website is a good source for relevant data.Greenhouses are structures designed to retain heat.Mars is too cold, and Earth is just right.What is a greenhouse and how does it work?How is the earth's atmosphere similar to a greenhouse?What are the limitations in comparing the earth's atmosphere to a greenhouse?Activity 12: What is a Greenhouse?Activity 13: What Factors Impact a Greenhouse?Sun's radiation reaches the surface.However, only a small portion
of this energy actually makes it back to space.Artificially created chlorofluorocarbons are
the strongest greenhouse gas per molecule.Termites also release methane through similar processes.If this assumption is correct, the
contribution from these insects may be important.Methane is also released
from landfills, coal mines, and gas and oil drilling.Coal, oil, and natural gas deposits
release methane to the atmosphere when these deposits are excavated or drilled.The use of nitrate and ammonium fertilizers
to enhance plant growth is another source of nitrous oxide.Greenhouse Effect: past and present concentration
and sources.This is an equatorial
band because that is where the atmosphere has the most water vapor.The earth has a natural greenhouse effect due to trace amounts of
H20 and CO2 that naturally occur.The
enhanced greenhouse effect refers to the
augmentation of these
natural gases by human activities.All the data on
greenhouse gas concentrations!This is
technically known as an Albedo .This, of course, exacerbates
the problem.This is not a real
significant energy loss.The earth has an equilibrium temperature
of about 300
Kelvins .This heat
is later released through condensation.This process is called
latent heat.In principle, CFCS are very bad and will dominate the
greenhouse gases in our atmosphere if their terrestrial usage
remains high.This
is far more serious that people realize or has been reported.The Greenhouse Effect Ltd is a specialist
