Global dimming is a gradual reduction in the amount of sunlight reaching the Earth's surface since the 1950s.
The results showed that in the three days after 9/11 that Global Dimming suddenly dropped. This proves that aeroplane contrails contribute greatly to Global Dimming.
Well it could be just the weather, but one hour since I took that photo the Sky has been replaced with thick heavy clouds.
Why is it always the same people saying the same thing over and over in chemtrail thread?
Don't you guys ever have anything better to do? Go outside once in awhile.
The average number of wet days (days 1mm or more of rain) ranges from about 150 days a year along the east and south east coasts, to about 225 days a year in parts of the west.
You do try so awfully, awfully hard, birdman!

I expect this was directed a'me.....com'on.....ye HAVE to speak in an Irish brogue......yah?
Look.....I'm of Irish stock....even if me borne in the States...I still ken me beginnings.......when I was in Shannon....I felt a presence, I must say.....in Shannon.....I think my ken are from there......I haven not felt so at 'ome an'where else.....
SO....look.....I grew up in the USA>...I speak "American English"....I type in "American" because that is what my keyboard offers. I SPEAK with an 'American' accent...though, I have an ear for other accents....I'm just not that good at it...
....POINT is......I have traveled 'round the World.....I am NOT a "typical American"......so, please don't sell me short. (Yeah.....it's an "Americanism"....."sell me short"....an idiom.....just do an Internet search on the phrase, and translate to your Iirish "English" for equivalents. I am not privy to ALL your slang....yet.....)
I am Irish....on me fathers' side....by me last name.......canna say more, just ken ye........

Yes, it is weather.
The conditions that make it possible for prevalent contrails to form usually mean that weather conditions are on the change.
Here....this may be a bit confusing at first, but with some study it becomes easier to interpret. It is just one example of a "North Atlantic Planning Chart", and it shows the sorts of "anchor points" that are used to define the North Atlantic Track (NAT) Routes, for the majority of air traffic between Europe and North America:
As you see, off the West coast of Ireland, there are many such "anchor" points (we refer to them as intersections.....in the old days...."waypoints" today, as they are primarily GPS-defined, now).
You see that whole slew of black triangles, that lie on the 15W meridian? All are identified by a five-letter name...this is how they are defined in aviation databases.
Anyway, not shown on that Aviation Chart are all the other various Airways....the routings that are assigned, and used, to get to those "anchor" points, to/from the various arrival/departure cites, per the airplane's flight plan.
For the UK and Ireland, there are Aeronautical Charts that show the layout of the High Altitude route system....called, ironically, "ATS" in Europe!
Not sure if I can find free online Aeronautical Charts further west of the British Isles as illustration....you can get them for free if you ask airline pilots, as they are discarded periodically because of revision cycles that replace older, outdated ones.
You may also purchase, online, any as well....if willing to shell out a few Pounds, Punts, or Euros .....:

The radiative forcing due to a distinct pattern of persistent contrails that form into contrail-induced cirrus near and over the UK is investigated in detail for a single case study during March 2009.
The development of the contrail-induced cirrus is tracked using a number of high-resolution polar orbiting and lower-resolution geostationary satellite instruments and is found to persist for a period of around 18 h, and at its peak, it covers over 50,000 km2.
A single aircraft operating in conditions favorable for persistent contrail formation appears to exert a contrail-induced radiative forcing some 5000 times greater (in W m2 km1) than recent estimates of the average persistent contrail radiative forcing from the entire civil aviation fleet.
This study emphasizes the need to establish whether similar events are common or highly unusual for a confident assessment of the total climate effect of aviation to be made.
Vapour trails caused by jet aircraft over Britain can cause clouds covering 20,000 square miles, according to Met Office research, reducing sunshine by up to 10 per cent.
Analysis of contrails from one large military aircraft circling over the North Sea showed the creation of a thin layer of cloud that, at its peak, covered an area of more than 20,000 square miles.
Researchers had expected high-level winds to disperse its contrails but instead they appeared to attract more clouds that continued to grow as they were blown southwards until eventually they formed a hazy high-level blanket of cirrus cloud across southeast England.

So the effects of artificial clouds caused by jet emissions were grossly underestimated. And it's just one plane that did this. Global dimming is a real concern and I would think it would particularly concern those living in areas that see fewer clear days than cloudy days to begin with.

It does not matter if the conspiracy is proven by now it is well over twelve years into the program and they have probably accomplished what they have intended.
However, what does that have to do with the the chemtrailers claim that the trails we see are NOT contrails at all, but rather the deliberate spraying of chemicals from secret aircraft for nefarious purposes?
Do YOU live in Ireland? Have you ever BEEN to Ireland?
Try to get a bit of travel under your belt, then come on back to ATS.....mK?

If only we could ALL have an "Antie Mame"!!!:

The effect that you're talking about from the jet emissions wherein they wind up covering the entire sky could be 'global dimming.' Jet emissions are postulated to make a significant contribution to 'global dimming.'
