Condensation trails

[Woodsy]

Can anyone give me information about the effect that con' trails have with regard to starting hazy conditions. I was playing golf this morning and notice at least twenty contrails in varying degrees of formation and dispertion. This was at 0800 hours and the sun was bright and there was no haze. However within an hour it appeared that the con' trails had cause a high level haze which reduced the sunlight perceptibly. Has there been any research into this aspect of aviation?:confused:

Thread has had a number of Off-Topic posts deleted and now remains patiently waiting for further input.

Hopefully back on track, there has been some talk of global dimming over the past few decades due to particulates in the air, and there was a programme (probably Horizon) about it. The main empirical evidence was after 11th September 2010 when there were almost no flights in the US for a few days and the tempreature difference between night and day changed by about 1 degree.
