@High Seas,
HS, Thanks for the online friendship; that means a lot to me.
As with most topics on a2k, my opinions are based on my many readings, and not from any scientific background. I was one of the first posters on a2k to question the effects of CO2 on our environment, but have since then changed my opinion based on climate scientists who say that CO2 have caused global warming.
Their latest findings by inspecting the ice in antarctica show the growth of CO2 since the industrial revolution, and the current ice melts there seems to support that conclusion.
Yes, I've heard of Galileo; who hasn't?
You call my opinions "baseless," but as I've said, I arrive at my conclusions from much reading on this subject. If my opinions are baseless, than the many scientist who agree with me are also baseless in their findings.
From pa.msu.edu:
Quote:How does carbon dioxide cause global warming?
(Lansing State Journal, August 31, 1994)
Fossil fuels such as gasoline, methane and propane contain mostly carbon. When these fuels are burned, they react with oxygen and produce carbon dioxide.
Because of our heavy use of fossil fuels, the amount of carbon dioxide in the atmosphere has been increasing since the industrial revolution. The destruction of forests which use carbon dioxide also contributes to the increase in carbon dioxide.
Most of the light energy from the sun is emitted in wavelengths shorter than 4,000 nanometers (.000004 meters). The heat energy released from the earth, however, is released in wavelengths longer than 4,000 nanometers. Carbon dioxide doesn't absorb the energy from the sun, but it does absorb some of the heat energy released from the earth. When a molecule of carbon dioxide absorbs heat energy, it goes into an excited unstable state. It can become stable again by releasing the energy it absorbed. Some of the released energy will go back to the earth and some will go out into space.
So in effect, carbon dioxide lets the light energy in, but doesn't let all of the heat energy out, similar to a greenhouse.
Currently, the amount of carbon dioxide in the atmosphere is increasing at the rate of about one part per million per year. If this continues, some meteorologists expect that the average temperature of the earth will increase by about 2.5 degrees Celsius. This doesn't sound like much, but it could be enough to cause glaciers to melt, which would cause coastal flooding.
