On the Subject program an explanation was given for why the "greenhouse ffect" causes global warming. The explanation was that Sun's infra-red is reflected back but by some unexplained process trapped in the atmosphere. Wrong. The reason for warming is based on "The Greenhouse" principle. But first you have to understand how a Greenhouse works.
The glass in a greenhouse is transparent to the infra rays of the Sun so the rays pass through and are absorbed by the inside which starts to warm up. When a body warmes up by absorbed energy it will in turn start to radiate heat. However the re-radiated heat has less energy than the infra red that warmed the body up.For infra-red that means that the re-radiated infra-red has a longer wave length. The glass is transparent to the shorter wave length from the Sun but it ir opaque to the longer wave length inside the greenhouse. So it is trapped and the insde warms up

Thus the earth warms up because the CO2 is transparent to the Sun's short wave infra-red but opaque to the long wave infra red radiated from the heat absorbed by the earth. If the suns rays were reflected back to space and we had no CO2 to trap the heat, our Planet would be too cold for Life.

Big business and Government control of the environmental movement has ruined the economy, and does very little good for the environment. This is because it allows the worse polluters to decide what is good and what is bad for the environment. There are hundreds of things that could be done other than Western bashing to solve the problem, Instead of dumping wast water into our rivers ,lakes our drinking water, every drop should be used to grow more trees Scientists have looked carefully at each of these factors. The only one where the data matches up is greenhouse gases -- levels of these gases have risen sharply as we burn more fossil fuels. If liberals were really interested in solving the problem, and not interested only in bashing industrialized nations, They would look for real solutions, The most logical solution is to increase oxygen in the atmosphere, rather than slow industrialization. One average size tree produces enough oxygen for breathing of 25 people. The average new home built would add 5 new trees to the world's best oxygen producers A simple solution in the US Is to force the US Government to release some of the millions an millions of acres, they are holding away from the people to control demographers for political reasons. GB advocates have already starved 100 millions Africans to death with their Western bashing agenda. Trees not only pump oxygen into the atmosphere they also pump moisture into the air. It doesn't rain much any more in Africa because most of the trees have been cut down in Africa and the Mid east.
