CONTRAIL FORMATION: SOOT REDUCTION MAY BE A RED HERRING
New research shows that lowering soot emissions by 1,000 times does not reduce contrail formation. Learn how this impacts aviation climate goals.

Recent flight tests show that lean-burn engines with 1,000 times less soot still create the same amount of warming contrails. This suggests current aviation climate plans need a major update.

On Super Bowl Sunday there were interesting contrails in the sky above San Jose.

✈️ 🌡️ How do contrails affect the climate? 🤔
Professor Dr. Susanne Crewell from the Institute of Geophysics and Meteorology at the University of Cologne gives us the answers.
Fact: Contrails from aircraft contribute to global warming. How exactly they contribute is shown in a study which is explained in our new issue of the #unimagazin ▶️ https://uni.koeln/KEV9B#uniköln #unicologne #unimagazin #climatechange #contrails #aircraft #climate

from an aerospace engineer:
"...If aircraft had variable camber systems (The A350 already has this), this should be literally free, the reason it increases fuel burn is because changing altitude can throw you off your design lift coefficient (CL), but variable camber effectively redesigns the wing in real time to re-optimise the wing for the new CL point. The potential performance recovery is insane. ..." -

from a comment:
"...warming effect comes only from PERSISTENT contrails. In certain conditions, over certain parts of the planet, contrails will form, and stick around, gradually spreading out and forming high altitude cirrus clouds. it is THESE which cause that warming effect. [...]We (military air forces) have been monitoring where such regions of the atmosphere are [...]so that fast jets are harder to pick out," -

#idw Study: “Hidden” #contrails in #cirrus clouds contribute to #climatewarming
Researchers at the Institute for #Meteorology at Leipzig University have, for the first time, determined the climatic impact of contrails that form within natural cirrus clouds. Contrails account for the largest share of aviation’s climate impact beyond carbon dioxide emissions. https://idw-online.de/en/news863338

(I KNEW it! The culprit are chemtrails!!1!11!!) (😁 sry, had to ^.^)
Not a bad idea, and also feasible, let's do that!

Long-lived contrails usually form in natural ice clouds: Research team identifies common environmental conditions for the formation of #contrails and provides initial insights into their impact on the #climate 👉 https://www.blogs.uni-mainz.de/fb08-pmc/long-lived-contrails-usually-form-in-natural-ice-clouds/

Using extensive observational data, the researchers were able, for the first time, to systematically determine the #atmospheric conditions under which long-lasting #contrails form – whether in cloudless skies, in very thin and barely visible ice clouds, or in more clearly visible ice clouds, known as #cirrus clouds.

It's been a great day for #contrails. I've been watching the flight paths and thinking, the #cookers will be in meltdown mode 🤔

This evening's contrails over my small town in the southeast of England must have really got the tinfoil hatters clacking! I don't know, but I can't bring myself to like them. One bonus of lockdown was the weeks without them! #Contrails #Skyscapes | #Kent #England
