Two theories - a big difference

Environment and weather experts have noticed a gradual increase in temperature over the entire earth over the last century and the last two decades in particular.One theory I have called the hydrocarbon theory;it posits that industrial processes that require  combustion release more and more hydrocarbons into the atmosphere.These hydrocarbons combine with the water vapour in clouds to form more and more dense clouds.These clouds have particulate matter and new gases that are more dense than ordinary clouds.These clouds allow the sun's rays to hit the earth's surface and after losing much of it's energy(largely photons) they do not have enough energy to bounce back and escape the magnetic belts and the new dense clouds.So the sun's rays remain in the atmosphere and warm up the earth's temperature as much as 3 to 4 degrees over the last century.
The second theory (the orbit theory) believes that the earth is largely contained by centrifugal forces to stay in a tight band rotating around the sun.This tight band is compromised by the movement outwards of the earth at a faster rate than the sun is moving.This process moves the earth closer to the sun as this tight band is stretched but not broken.In fact, as the earth's movement outwards starts to slow down the normal orbit will gradually take shape again.This theory believes that the earth may warm up another 1 or 2 degrees and then start to cool.
The difference is that the earth is not warming up because of  industrial processes and for example the combustion used to create heavy oil in the Alberta Tar Sands does not affect "global warming"
