Do aircraft vapour trails form clouds? I ask this, as this evening ,the sky out to towards Wales had lots of vapour trails,that looked to be expanding to form small clouds,if this is so surely they must be effecting our weather.
they weren't very clear over northern Europe,After the eruption of the Eyjafjallajokull volcano and the subsequent grounding of aircraft, the skies over Dorset were the clearest I've seen before or since. It would be interesting to see the increase in solar radiation figures from solar farms around that time.
sorry they were not vapor trails i was trying to start a David brownDo aircraft vapour trails form clouds? I ask this, as this evening ,the sky out to towards Wales had lots of vapour trails,that looked to be expanding to form small clouds,if this is so surely they must be effecting our weather.
Nah they simply release moisture,which in itself the atmosphere is full of anyway.
Try the cockpit view.

Please tell us more.Aha! The old chestnut.
One of my students a few years back led a research programme and found that contrails do have an impact on global temperatures.
It's a fascinating area.

The beginning of the end of the great global warming lie:

I thought nasa had done many studies over many years and concluded that there was increased cirrus cloud coverage over high air traffic routes, and as that increases it becomes globaly significant.Please tell us more.
yes...except it says nothing about ocean heat energy accumulation and the 15 years taken is cherry picked data.
Thought we were talking climate not weather. Yes the rise in global land temperature has levelled off but thats because the oceans are accumulating heat instead... .
So what's suddenly made that happen - the great sweeping hand of Almighty God perhaps? If you ask me these 'scientists' will invent any old barmy theory to perpetuate the global warming myth no matter how much contradictory evidence lands on their doorstep.
Sorry for calling it Global Warming, I see that as they have discovered that there's no such thing the scientists have re-named it 'Climate Change.' Did anyone notice how the scientists and politicians swapped from calling it global warming to climate change overnight? That must have been the result of many emails flying around
Sorry this is wrongA climate change programme - so time ago - noted that after 9/11 the temperature around USA rose slightly. The arguement was that as most aircraft were grounded there was no shading from the vapour trails. Maybe not big enough to form clouds but they must be blocking the sun. Somewhat ironic that burning fossil fuels should cool the planet?
