Ecologic urgency : Air traffic excess

Gah. For pete's sake stop this utter nonsense. These photographs are not evidence of anything, they are laughable, really, really laughable. The first is taken directly into the sun using a digital camera - the light has saturated the CCD sensor ("over exposed" in old terminology) which means that any colour information has been lost - from that photogrpah it is impossible to tell the colour of the sun. The second picture is of a tin-roofed building in what is obviously a high altitude location with snow covering the ground - Because tin is a good conductor it will be uniformly very cold and covered with microscopic ice crystals (frost) - it is those ice crystals that are reflecting the sunlight (or moonlight?) not the "dark surface".

Let's come back to the first pic: it's a photographic artefact, according to you. So the sun was yellow and the picture made it
white and star-shaped whereas it was yellow and round.
Do you often see yellow sun during the day in your area (or anywhere else)?

...were my comments really reported?

Mine had to be hidden even though it seems like his comment was the one that caused you to hide them?

If that is the case, I'm going to post my picture again.

"Children use yellow becaue they are "conditioned" to use yellow from kindergarten, all depictions of the sun in children's books are yellow - they are copying those, not the sun itself."


And why the sun was pictured as yellow in children books?

I explained that in the following paragraph: "The sun looks yellow at the only times when it is (relatively) safe to look at it, which is at sunrise and sunset. Since the sun looks yellow then it is implicit that the sun is always yellow even when it is too bright (dangerous) to look directly at it. "  

Certainly solar activity has an impact on us but probably not on the sun colour which is only due to the atmosphere composition IMO.

BTW Sean, we installed several luminotherapy bulbs at home last winter (because the sun has became so rare that we needed compensation) and it's the "spring light", white light.

What lead us back to the topic issue: usually the sunlight is white in Spring and yellow mellow in Autumn. Now it's white and blazing
all the time, whatever the season but i understand that it's too subtle for many.
